Cactus fascinates me, does it run on code similar to an existing instruction set or is it completely original on that front?

What can you do with it? What's it's storage?

Both the Cactus (the original wooden prototype from years ago) and the new PCB Cactus(es) are essentially derived from a minimal 6502 computer design by Grant Searle for their core logic. Here's what that would look like on a breadboard:

There isn't much to it, it's 32K of RAM, 16K of ROM containing Ohio Scientific's version of Microsoft BASIC, a 6850 ACIA for serial interaction, some logic gates, and of course a 6502 microprocessor (NMOS or CMOS, doesn't matter which). You hook it into a terminal and away you go.

Grant's design in turn can be best described as a distilled, modernized version of the OSI Challenger series of computers. Here's an OSI-400 and a Challenger 4P respectively:

The left one is a replica of the 400 circa 1976, also called the Superboard. It was affordable, endlessly reconfigurable and hackable, but ultimately very limited in capabilities. No BASIC, minimal monitor ROM you talk to over serial, but you could connect it to a bus to augment its features and turn it into a more powerful computer.

Whereas the OSI C4P on the right from about 1979 has more RAM, a video card, keyboard, BASIC built in, serial interface, cassette tape storage, and that's just the standard configuration. There was more room to expand and augment it to your needs inside the chassis (alot changed in 3 years for home computer users).

Grant's minimal 6502 design running OSI BASIC is a good starter project for hobbyists. I learned about the 6502's memory map decoding from his design. I modified and implemented his design on a separate cards that could connect to a larger backplane.

Here are the serial, ROM, RAM, and CPU cards respectively:

Each one is 100% custom, containing many modifications and fixes as I developed the design. However, that's only half of the computer.

I really wanted a 6502 machine with a front panel. People told me "nobody did that", or couldn't think of examples from the 1970s but that seemed really strange to me. Especially since I had evidence to the contrary in the form of the OSI-300:

This one I saw at VCF West back in 2018 illustrates just how limited of a design it is. 128 bytes of RAM, no ROM, no serial -- just you, the CPU, and toggle switches and LEDs to learn the CPU. I was inspired the first time I saw one in 2015 at VCF East, which is probably when this whole project got set in motion.

Later that year I bought a kit for a miniature replica OSI-300 made by Christopher Bachman, and learned really quickly how limited the design philosophy for this particular front panel was. It was a major pain in the ass to use (to be clear, that's by OSI's choice, not any fault of Christopher in his implementation)

So... I designed my own. Took awhile, but that's the core of what the Cactus is: my attempt at experiencing the 1970s homebrew scene by building the computer I would have wanted at the time. Over half of the logic in the Cactus is just to run the front panel's state machine, so you can examine and modify the contents of memory without bothering the 6502. I added in all of the things I liked from more advanced front panels I had encountered, and designed it to my liking.

Here's the original front panel, accompanying logic, and backplane connected to the modern single board computer (SBC) version of the machine:

And here's the new Cactus SBC working with the new front panel PCB, which combines the logic, physical switch mountings, and cabling harnesses into a single printed circuit board.

So, what can you do with it? Pretty much the same things I do already with other contemporary 1970s computers: play around in BASIC, fire up the occasional game, and tinker with it.

I've got no permanent storage designed for the Cactus as yet, it's been one of those "eventually" things. The good news is that a variety of software can be ported to the hardware without too much trouble for an experienced hobbyist. A friend of mine wrote a game called ZNEK in 6502 assembly which runs from a terminal:

Right now, you have to either toggle in machine programs from the front panel from scratch, burn a custom ROM, or connect it to a serial terminal to gain access to its more advanced features:

Here's it booted into OSI BASIC, but I have also added in a modern descendant of Steve Wozniak's WOZMON software for when I need to do lower level debugging.

I've also got a video card now, based on the OSI-440. I have yet to implement a keyboard, or modify BASIC to use the video board instead of the serial connection. Even if I did, screen resolution is pretty limited at 24x24 characters on screen at once. Still, I'm working on that...

Anyway, I hope that answers your question. Check the tags below to see the whole process stretching back to 2017 if you're curious to learn more of the project's history. I'm also happy to answer any more questions you might have about the project.

A controller with a scroll wheel, you say?

Well this is a little funny. Yesterday I posted the first part of a series of post on the fine details of how computers work, mentioning how I've been looking into this as part of a personal project I've been working on, and today I wake up to see Masahiro Sakurai posting a youtube video lamenting the lack of... this exact thing I'm working on.

Apologies for how much cat hair is in this photo, that's a bit of an occupational hazard, but this here is a photo I took back in September when most of the parts I had to order were in for the prototyping of this thing:

That's a really bad MS Paint mockup, but yeah. I'm designing my own game console, and one of the key features is a big ol' scroll wheel right in the center of the controller. Another is that I'm planning to just put all the designs of the circuit boards and 3D printer files for the casing/buttons up online for free, making it this totally open DIY thing where anyone who's a big enough nerd can just make a couple downloads, order some dirt cheap components, and build their own copy of the system (or people with better setups than me can build and sell them, whatever). So I'm not super worried about anyone stealing my ideas or whatever, but I WOULD like to establish a standard and all that, and figured it was worth noting that this is something I've been slowly working towards for like a year or two now, and didn't just get the idea from this video:

But yeah, now that the idea's out in the public consciousness, here's the plan for the controller (that I was planning to keep under my hat until I had a working prototype and some demo software sometime next year).

First off, the plan is that this is to be the standard controller for a whole console I'm also plucking away at designing, which is a bit more ambitious of a project, so I figure I might as well make it compatible with something that's already out there. So specifically, I'm designing this so that you can take one, plug it right into an SNES (or with a different connector at the end, an NES, because turns out they use the exact same input handling standard and it's just the shape of the plastic on the end that differs), and have it just work. Or mostly work anyway. I'm hoping I can process a signal out of the scroll wheel in a way that it either just needs the 3 extra bits of the input signal I don't have buttons for in my design (more on that later) or failing that, I can get it to output the same sort of signal as one wheel in the SNES mouse, which just rides along the second data line very few things use. I think that plan might break multitap compatibility and require an extra chip on the controller PCB, but it would leave this slightly more compatible with existing games on the same hardware. I might also do something weird with the button mapping to be sure NES select is on a shoulder and it works right out of the box with that whole library.

Working out exactly how to handle signals from the scroll wheel happens to be the point I'm currently stuck on by the way. I got this baggie full of rotary encoders for just a few cents which... almost fit in my first draft 3D printed wheel housing, but I have NO documentation on them, not even a part number/manufacturer besides "H-9," the pins don't fit a breadboard, and I've kinda been scrambling for rent so I can't afford a nice multimeter or oscilloscope to poke around with. Plus again I need to redesign this wheel print to even get it to spin right, and... this was a gift from a friend with a printer who is Not Local. Solvable problem, just needs more time and/or outside expertise.

But yeah, once I have those kinks worked out, it should be easy enough to get a custom board design made, replicas of end-cap of the controller cord are another problem easily solved by ordering a 1 dollar part or 3D printing something. The actual cord might be tricky since I don't know where you actually order something like that from, but it should be easy enough for anyone who doesn't mind a little assembly work to put one of these together and have it good to go for any software made with it in mind, or retrogames where you don't mind a weird button count. So... what's the pitch on this scroll wheel anyway?

Well for starters, there's the stuff Sakurai got into this morning. Any sort of RPG or text heavy game can use it to quickly scroll through menu options, or stuff in a text-heavy game. You could also pan the screen with it, something a lot of early 16-bit games assigned to the shoulder buttons or holding up and down while getting used to the new options the hardware was giving them.

Past that, you'll notice in my design it's at a 45 degree angle. I might have to tweak it a little, but my thinking is for a game that uses it heavily, one thumb or the other can slide over easily enough (I'm going for a pretty compact overall design) so we can have some games where you take your thumb off the D-pad, and have this nice analogue steering wheel. Nice for fine control in a racing game, or if you want some little radio-tuning/safe-cracking sorta deal.

Alternatively, move your right thumb over, use the D-pad to steer, shoot and dodge or whatever with shoulder buttons, and use the wheel to rotate a turret for a twin-stick sort of game maybe.

Or just use it for the sort of stuff mouse based games stick on the scrollwheel. Changing weapons, changing powerups... I'm planning to officially label the directions "hot" and "cold" to encourage weird gimmicky things like... I dunno, a platformer where you have a thermostat in your controller you can always mess with, freeze water coming out of pipes, crank up flame jets? Have a shot charging mechanic where you just really crank it to get to max strength? Weird minigame stuff. There's some fun space to explore with it.

Then we have the rest of the design here... which basically comes down to me being just plain sick of how every controller made by anyone in the past... 20 years give or take has kind of the exact same layout? 4 good face buttons, a D-pad, 4 shoulder buttons, 2 sticks, and 1-4 annoying to reach tiny awkward middle buttons, and we're just kind of overdue for a change-up?

Like first of all, hey, this is just too many buttons. There's a ton of games that really only need a D-pad, and maybe 3 buttons (attack jump pause) and the two things that aren't fully standardized is how awkwardly placed the D-pad is and how awful and awkwardly placed the pause button is. Shoulder buttons can be nice, but I've never really felt like 4 of them awkwardly crammed on the rim has been really useful or ergonomic, and that's coming from someone who's been playing a ton of FF14, which gets more use out of them than anything else I could name. And really, aside from games doing fake twin-stick stuff and using the whole grid like a second D-pad, I'm having a really hard time thinking of any game I've ever played that really makes good use of 4 good face buttons? Like people will use them if they've got'em sure, but unless you do that keyboard style thing where you lay the controller on a table and use all your fingers, you can really only comfortably hit 2 face buttons without sliding your thumb away from them, maybe comfortably make a quick pivot to a third.

Also, really, a lot of designers just sort of feel compelled to map SOMETHING to every button, even if it's clear the design didn't really need them. So basically I figure I'll try kinda just taking a "less is more" approach here. Here's the buttons that it's comfortable to rest your thumbs and fingers on, here's a dedicated pause/menu button where people often stick a kind of redundant menu button, here's my gimmicky scrollwheel. That's it, work around that.

I'm also going a little Gamecube inspired (literally using replacement membranes for one in my prototype design, even). Gonna make a great big primary button and use different shapes for the other two. Trying to label these in a less arbitrary fashion than most. If shooting a gun is a thing you do in this game, and there isn't a real good reason not to, default it to this nice right trigger you can hold down all the time. If we're advancing through menus or jumping or holding down gas in a car, here's the big GO button. Need brakes, need to break stuff with a melee attack? Go back in a menu system? There's your other face button. Have a quick dash move or a run you hold down, let's just use the other shoulder.

So yeah. That's my controller. Need to work out the kinks on the scroll wheel, source a cord, and hopefully I can slap things together and this will be something you can just order bits for piecemeal and put together for like, $5-10 after shipping? Maybe less? The parts are shockingly cheap so far.

But yeah if anyone has any insight to the scroll wheel or cord issues, let me know. Also the whole thing is presently a tad back-burnered because I am in a serious financial crisis and I don't want to have electronics spread all over my table if I have to abruptly find a new place to live if I can't scrape next month's rent together. So as usual, donations are incredibly welcome.

Let me introduce my current main WIP. It's not fandom related, it's for my model railroad, and it's not yet finished.

This is a rendering of a circuit board that I'm designing at the moment. It will be a DCC command station. My model railroad is run digitally, which means the tracks carry digital signals that tell each locomotive and switch individually how to run, which lights to turn and so on. The command station is the device that generates that. I have a number of different layouts, one of which has a good command station, one of which has a crappy old one, and the final one isn't even digital yet. So this will be the one that solves all issues for me, hopefully.

The design above isn't finished yet, and even the parts that are are not yet fully representative. The different capacitors are just there as options; some screen print overlaps; and some components (in particular all plugs and the relays that control the programming track) don't have 3D models so they don't show up.

Planned features:

Four layer board

10-25 V DC output, software controllable

Up to 5A output power, limited mainly by the main switching regulator.

Input 15-25V either AC or DC with polarity protection, selectable with some solder bridges (not yet in there). Optionally you can also bypass the main power regulator with another solder bridge (that I haven't added yet); useful in case you use e.g. a laptop power supply with a switchable voltage and don't need any regulation after that.

Railcom support

USB connection; not yet sure what for, but the main chip I'm using has USB support and I have some spare USB connectors here, so in it goes.

Speaking: The chip is an STM32L433RCT6P, chosen because I found it in stock at an electronics distributor. 64 kB RAM, 256 kB EEPROM, with support for an additional up to 256 MB externally (there's a spot for that on the board) and lots of fun extras that I don't technically need. It has an FPU! I don't need an FPU, but I will definitely do some floating point math computation on it just for fun.

Main external connection is WLAN using an ESP32 WROOM U module. I haven't decided on the housing, but I may go for extruded aluminum, so it's the U version that allows and requires an external antenna

It supports XBUS/XpressNet connections for old throttles from Lenz and Roco that I should probably throw away, but I paid good money for them, dang it.

It supports CAN for LCC / OpenLCB. I may not populate this part on all boards that I'm building, because I haven't actually decided whether I am interested. But the chip has CAN functionality built in, so why not.

There's an I2C connection to connect a cheap tiny OLED display for status messages.

Test points for all important signals (in particular the different internal voltage levels; yes, there is 3.3V, A3.3V and -3.3V and I need all of them).

Stuff still to add:

I will add pin headers (or space for pin headers anyway) for all the remaining pins on the STM32, and perhaps some on the ESP32, for future expansions.

Status LED and stop/go button on the front

Wire it all up, maybe move some stuff (mostly the STM32 around), which will cause all sorts of fun new routing issues.

Adjustments to make the jacks line up with the front panel once I've decided on a housing.

Features I'm not considering adding:

s88. I vaguely know what it is but I don't have any devices like that, and if that ever changed I could probably build (or perhaps buy) a converter that connects them via CAN.

Other buses like LocoNet.

Ethernet. I don't need it and it's actually more expensive than WLAN in this day and age.

In terms of software, I'm planning to use DCC-Ex on it. The whole project actually started out as a DCC-Ex shield, but once I realised that this wouldn't fit, I decided to make it standalone. Now, DCC-Ex is designed for Arduino, not STM32, and it doesn't support XpressNet, nor OpenLCB, nor Railcom, and their Wifi protocol is pretty weird and annoying which will be an issue (I'm planning to write my own control app for iPhone for it), so I'll probably change that or just replace it with the z21 one… so really, the software will not look a lot like DCC-Ex once I'm done with it.

Will this all work? I have honestly no idea. I mean, I'm fairly confident, I'd have given up on this long ago otherwise, but I have no guarantees either way until I've spent a lot of money on components and circuit boards and start soldering. Turns out doing it this way is not really cheaper than just buying a half-way decent one. That's what makes it exciting, though!

If it does work, obviously this will be released as open source. But it's still going to be a few days (more realistically weeks) before it's even ready to order the parts, and then a lot of soldering (current BOM stands at 194 actual components), and then a lot of software development before it's ready for that.

Printed Circuit Board (PCB): The Backbone of Modern Electronics

A Printed Circuit Board (PCB) is an essential component in nearly all electronic devices. These boards are designed to mechanically support and electrically connect various electronic components using conductive pathways. The significance of PCBs in today’s technological landscape cannot be overstated, as they form the foundation upon which most modern electronics are built. Whether it's a smartphone, computer, or even complex industrial equipment, the PCB plays a crucial role in their functionality.

Structure and Components of a PCB

At its core, a PCB is made up of a non-conductive substrate material, typically fiberglass or composite epoxy, with conductive copper traces embedded on it. These traces form electrical circuits that allow components such as resistors, capacitors, transistors, and integrated circuits to communicate and work together. The components are mounted onto the board through a process called soldering, where a metallic substance binds them to the copper pads, ensuring strong electrical connections.

There are several layers in a typical PCB:

1. Substrate Layer: The base material, often fiberglass, provides rigidity and insulation.

2. Copper Layer: A thin copper foil is laminated onto the substrate, forming the conductive pathways.

3. Solder Mask Layer: This is a protective layer that covers the copper traces, preventing short circuits and oxidation.

4. Silkscreen Layer: Used for printing labels and markings, this layer helps technicians and engineers identify components on the board.

PCBs can range from simple single-layer boards to more complex multi-layer boards. In advanced applications, multi-layer boards are used, where multiple copper layers are sandwiched together with insulating layers between them. This allows for higher component density and more complex circuitry in a compact form factor.

Types of Printed Circuit Boards

PCBs come in several different types based on the complexity of the design and the needs of the application:

1. Single-Sided PCB: The simplest form, with components and copper traces on one side of the substrate.

2. Double-Sided PCB: These boards have components and copper traces on both sides of the substrate, offering more flexibility for routing electrical connections.

3. Multi-Layer PCB: As the name suggests, these boards have multiple layers of copper traces, making them ideal for complex and high-performance applications.

4. Rigid PCB: These are made from solid, inflexible materials, commonly used in devices where the board must maintain a specific shape.

5. Flexible PCB: These boards are made from flexible materials and can bend, fold, or twist. They are often used in compact devices where space is limited.

6. Rigid-Flex PCB: A hybrid of rigid and flexible PCBs, these are used in complex devices that require both flexibility and stability in specific areas.

Manufacturing Process

The manufacturing of a PCB involves several precise steps to ensure quality and reliability:

1. Design: The process begins with creating a design using PCB design software. This includes defining the layout, trace routing, and component placement.

2. Printing the Design: Once the design is finalized, it is printed onto the copper-clad substrate using a photomask or a direct laser printing method.

3. Etching: Any excess copper is removed from the board, leaving only the desired copper traces.

4. Drilling and Plating: Holes are drilled where components will be placed, and conductive materials are plated inside these holes to establish connections between layers in multi-layer boards.

5. Solder Mask Application: A solder mask is applied to protect the copper traces and prevent short circuits.

6. Silkscreen Printing: Component labels and identification markers are printed onto the board.

7. Testing and Quality Control: The finished PCB undergoes rigorous testing to ensure there are no defects in the circuitry or connections.

Applications of PCBs

PCBs are found in a vast array of electronic devices and systems. Some of the key application areas include:

Consumer Electronics: Smartphones, tablets, computers, and home appliances rely heavily on PCBs for their operation.

Automotive Industry: Modern vehicles contain numerous electronic systems, from engine control units to infotainment systems, all powered by PCBs.

 Medical Devices: Precision medical equipment like diagnostic machines and wearable health devices depend on reliable PCBs for accurate functionality.

Telecommunications: Communication devices, including routers, switches, and mobile towers, are equipped with PCBs that handle data processing and signal transmission.

Aerospace and Defense: In high-stakes industries like aerospace and defense, robust PCBs are required for mission-critical systems, including avionics and radar equipment.

Future Trends in PCB Technology

As technology continues to evolve, so too does the development of PCBs. Advances in materials science, miniaturization, and automation are paving the way for even smaller and more powerful PCBs. Innovations such as flexible hybrid electronics (FHE), 3D-printed circuits, and high-speed PCB designs are expected to revolutionize industries by enabling more compact, lightweight, and efficient electronic devices.

Moreover, with the rise of the Internet of Things (IoT) and 5G technology, the demand for high-performance PCBs capable of handling greater data transmission speeds and power efficiency is surging. This trend will likely lead to more widespread use of multi-layer and flexible PCBs in upcoming technological advancements.

Conclusion

The printed circuit board is undeniably one of the most vital components in modern electronics. Its evolution has allowed for remarkable advancements in technology, from the devices we use daily to the complex systems that run industries.

How to Choose the Best PCB Design Tool for Your Project

Printed Circuit Board (PCB) design tools are crucial for electronic engineers and designers. They facilitate the creation, modification, and validation of circuit boards, making the design process efficient and error-free. However, selecting the right PCB design tools is challenging, given the wide variety of options available in the market. This article will guide you through the factors to consider when choosing the best PCB design tool for your project, ensuring you make an informed decision that meets your needs. Choosing The Best PCB Design Tool for Your Project Understand Your Project Requirements The first step in selecting a PCB design tool is to evaluate the specific needs of your project. Not all tools offer the same features, so understanding your project's demands is crucial. - Complexity: Is your design simple with a single-layer PCB, or does it involve multiple layers with complex circuits? - Type of Components: Are you working with analogue, digital, or mixed-signal designs? Some tools specialize in one or the other. - Size of the Project: How many components are involved, and how large will your PCB be? If you are working on large-scale projects, you’ll need software that supports complex designs. Ease of Use The learning curve of PCB design software can vary significantly. If you are a beginner, look for user-friendly tools with intuitive interfaces.
