How does an engine contribute to a car's powertrain?

The powertrain in a vehicle is the system responsible for generating power and delivering it to the wheels to propel the vehicle forward. The operation of a powertrain can vary depending on whether the vehicle is powered by an internal combustion engine (ICE) or an electric motor (in the case of electric vehicles). Here's a general overview of how a powertrain works in both types of vehicles:

Internal Combustion Engine (ICE) Vehicle - Combustion Process: In an ICE vehicle, the powertrain starts with the combustion process in the engine. Fuel (gasoline or diesel) mixes with air in the combustion chamber and is ignited by spark plugs (in gasoline engines) or compression (in diesel engines).

Power Generation: The combustion process generates energy in the form of mechanical power, causing pistons to move up and down within the cylinders of the engine. This motion drives the crankshaft, converting linear motion into rotational motion.

Transmission: The rotational motion from the crankshaft is transmitted to the transmission, which consists of gears that allow the driver to select different ratios (speeds). This enables the engine to operate efficiently across a range of vehicle speeds.

Drivetrain: The transmission sends power to the drivetrain components, including the driveshaft, differential, and axles, which transfer power to the wheels. The differential allows the wheels to rotate at different speeds, enabling smooth turns.

Wheel Movement: The power transmitted through the drivetrain causes the wheels to rotate, propelling the vehicle forward or backward depending on the gear selection and throttle input from the driver.

Electric Vehicle (EV) -

Battery Pack: The primary source of power for the EV, storing electricity in chemical form.Powers the electric motor and provides electricity for all electronic devices within the EV.

Battery Management System (BMS): Monitors battery cell conditions, including voltage, current, temperature, and state of charge (SoC).It protects the battery against overcharging, deep discharging, and overheating and helps balance the charge across cells. Ensures optimal performance and longevity of the battery by regulating its environment.

Inverter: Converts DC from the battery pack into AC to drive the electric motor.Adjusts the frequency and amplitude of the AC output to control the motor’s speed and torque. Critical for translating electrical energy into mechanical energy efficiently.

Onboard Charger: Facilitates the conversion of external AC (from the grid) to DC to charge the battery pack. Integrated within the vehicle, allowing for charging from standard electrical outlets or specialized EV charging stations. Manages charging rate based on battery status to ensure safe and efficient charging.

DC-DC Converter: Steps down the high-voltage DC from the battery pack to the lower-voltage DC needed for the vehicle's auxiliary systems, such as lighting, infotainment, and climate control. Ensures compatibility between the high-voltage battery system and low-voltage electronic components.

Electric Motor: Converts electrical energy into mechanical energy to propel the vehicle. It can be of various types, such as induction motors or permanent magnet synchronous motors, each offering different efficiencies and characteristics. Typically provides instant torque, resulting in rapid acceleration.

Vehicle Control Unit (VCU): The central computer or electronic control unit (ECU) that governs the EV's systems. Processes inputs from the vehicle’s sensors and driver inputs to manage power delivery, regenerative braking, and vehicle dynamics. Ensures optimal performance, energy efficiency, and safety.

Power Distribution Unit (PDU): Manages electrical power distribution from the battery to the EV’s various systems. Ensures that components such as the electric motor, onboard charger, and DC-DC converter receive the power they need to operate efficiently. Protects the vehicle's electrical systems by regulating current flow and preventing electrical faults.

In both ICE vehicles and EVs, the powertrain's components work together to convert energy into motion, enabling the vehicle to move efficiently and effectively. However, the specific technologies and processes involved differ significantly between the two propulsion systems.

Fell in love with that Razr =w=; (except that shitty fingerprint sensor)

DISHONORABLE MENTIONS

Curved displays are a FUCKING MISTAKE

Look up my beautiful baby girl the Nexus 4. Curved glass edges, but not, the SCREEN. (also the glass back is so thin that bitch bent so far with a spicy pillow in it and didn't shatter. Didn't understand the hate for glass backs till I got an OP6 and it fell like idk 2 feet from couch to not a hard floor)

We will be LAYING in fucking bed and because of how we have to support it so that, ya know, it doesn't hit our face. Stupid fucking shit be getting activated on the sides ALL THE TIME

Removal of RGB notification LEDs.

'nuff said. This could actually be replicated on AMOLED's. We found an app but its so jank compared to just a tiny fuckin' DOT we stopped using it.

Hate rounded corner screens. And non rounded screenshots MAKE IT MATCH AT LEAST. But also just give me back angles gfdi

Tablets and some phones should take a full size SD card and not have the slot combined into the fucking SIM slot that's fucking stupid

I'm not very fond of most gimmicks or changes that have come to 'modern' smart phones.

I don't think the punch-hole style of selfie cameras or in-screen fingerprint readers have been necessary nor beneficial additions. (and let's not forget the culling of headphone and μSD slots from all but Sony phones)

But I will say, it's not taken long for a folding phone to win me over. The necessary mechanical and material additions over a normal phone give it a nicer tactile feeling than the slim, featureless, glass or metal of more recent phones.

It feels very much like 'an gadget' - which has surprised me a lot. Both in the way it looks - especially with a chunky case - and in tactility. A very welcome feeling.

The front screen is handy for 'at a glance' stuff I'd lost since ditching a smart watch, and isn't completely pointless feeling.

Now if only we could get physical keyboards back in phones....

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.

Prowler by David Buckley, in Sinclair Projects, Aug/Sep & Dec/Jan 1983. Prowler is a low-cost, expandable micro robot vehicle, controlled by a host computer. "So far the available robotic add-ons have needed either complex software to interface them to a home computer or have been too costly, or too big. The BBC Buggy costs more than £100 and even Zeaker, the latest of the add-ons, costs slightly more than £50. Projects Prowler in its first stage of development should cost about £20. Prowler consists of a converted remote-controlled s-scale tank kit, with a circuit board holding some electronics to control the motors, lights, horn and later some bump sensors." – Prowler control adds movement to the ZX81, Sinclair Projects

🎄💾🗓️ Day 7: Retrocomputing Advent Calendar - Altair 8800🎄💾🗓️

The Altair 8800 was one of the first commercially successful personal computers, introduced in 1975 by MITS, and also one of the most memorable devices in computing history. Powered by the Intel 8080 CPU, an 8-bit processor running at 2 MHz, and initially came with 256 bytes of RAM, expandable via its S-100 bus architecture. Users would mainly interact with the Altair through its front panel-mounted toggle switches for input and LEDs for output.

The Altair 8800 was popularized through a Popular Electronics magazine article, as a kit for hobbyists to build.

It was inexpensive and could be expanded, creating a following of enthusiasts that launched the personal computer market. Specifically, it motivated software development, such as Microsoft's first product, Altair BASIC.

The Altair moved from hobbyist kits to consumer-ready personal computers because of its modular design, reliance on the S-100 bus that eventually became an industry standard, and the rise of user groups like the Homebrew Computer Club.

Many of ya'll out there mentioned the Altair 8800, be sure to share your stories! And check out more history of the Altair on its Wikipedia page -

Behind the Fortress Walls Chapter 4

We've finally got chapter 4 of my bang fic out! Only one more to go, holy shit.

Fic Summary:

Jazz is in love with Dick. He’s kind, considerate, and caring. Far and away the nicest person she’s ever dated. But she’s lying to him. About so, so much. And he’ll hate her once he learns the truth. Assuming he doesn't get tired of her canceling all their dates first. When Danny and Ellie go missing, the latest in a series of ghostly disappearances, she's forced to cancel another date. Going to Elmerton to meet up with Tucker and Sam, she will get Danny and Ellie back from the GIW no matter what it takes. Only...they aren't the only ones breaking in.

Chapter word count: 8.1k

There's an entire comic included with this chapter. Or you can find it on tumblr here.

The scene from the comic:

-----

The hallway ended in a thick metal door that had both electric and manual locks. Before Dick could even offer to take care of it, Tucker shrugged off his own backpack and pulled out a tool kit. Within moments, he had the casing off the keypad and was plugging his own PDA into the system.

Starfire hovered over his shoulder, looking down. “What is the purpose of the device you are using?”

Jazz could hear the smile in Tucker’s voice as he caressed his PDA. “Bethany here is my pride and joy, my child. She’s capable of anything.”

Sam snorted. “It’s a PDA. Not our kid, T— Pharaoh.”

Tucker made hushing noises and clutched Bethany to his chest. “Shhh, you didn’t hear that. Mommy loves you.”

“Just get the door open,” sighed Sam.

“Not until you apologize to our daughter!”

Sam took a deep breath to respond, but Danny interrupted before she could. “Just do it, Regrowth. Pharaoh and I put a lot of work into Bethany.”

Sam’s shoulders slumped. “I’m sorry, Bethany. I love you very much.”

Starfire grinned. “The machine is alive? It is nice to meet you, Bethany!”

Next to her, Jazz felt Dick shake with barely suppressed laughter. When she looked out of the corner of her eyes, she could tell he was biting back a smile.

Sam sighed. “She’s not alive. But Pharaoh and Phantom have been developing and upgrading her over the last several years. They’ve custom built half her parts and replaced the other half.”

Dick hummed in interest. “It looks like an old PDA case. Why didn’t you go for something more modern?”

For the first time that night, Danny grinned at Dick and Jazz felt something inside her relax. “PDAs were what we could afford as teenagers without real jobs. Plus they have bigger casings than modern smart phones; more room to fit more hardware. Beth’s battery lasts weeks.”

Starfire laughed. “Cyborg wishes to know if you would agree to the sharing of specs.”

Tucker practically squeaked at the question and Jazz bit back her own laugh. “Uh, yeah. Sure. Absolutely. He really wants to see?”

“Pharaoh,” said Dick, “if you allow it, he wants to spend at least a week with you figuring out how the tech these guys use works.”

Tucker looked down at Bethany and began typing. “I mean, sure. I’d love to. But if that’s what he wants, D would really be better. He’s the hardware guy, I’m the software guy.”

A moment later, the keypad beeped and they heard a click.

“All right, electronic locks are open. Nightwing, mind getting the rest of them?”

Dick grinned as he sauntered up to the door and pulled out his lock picks again. This door took longer than the first, but even so, it was open in just a minute or two. Dick bowed as he pulled the door open and gestured them through.

He revealed a fairly small room, in the center of which sat what looked like a large boiler with a monitor affixed to it. The glowing green wires spread out of the machine and disappeared into the walls, ceiling, and floor.

Hope you enjoy the chapter!

So it’s weird to come back a couple years after you leave a place and see how it’s changed, right?

In my first year of college, a group of friends and I were the first iteration of our college’s Makers Club. The tech teachers helped us get set up, taught us to apply for funding, got us a room for meetings

And, y’know, for most of the year what we in the club had access to was the room, a projector, and the xbox one of the members brought in for our weekly Smash Bros tournament

(Before the xbox came in the Makers Club did vitally important and scientific activities like taping a member to a chair with painter’s tape to see how easily he could break out)

And as we did the budget request, we all made jokes about stupid things we could buy, because we needed to have an itinerary of everything we wanted to submit with the budget, and the teachers advised us to ask at least double what we actually wanted

(So, 10’ diamond coated charger cables, better tape, a 3D printer to print a trophy for the winner of the tournament each week, etc.)

It was basically a lunch club, almost entirely of people from our software development classes, where we all hung out and dicked around

I graduated a couple years later, and the year after that snuck back to the Maker’s Club because we’d finally gotten a 3D printer the year I graduated and I wanted to get a sneaky print cuz we charged for the filament and not much else

And gang

I saw this club when we had A Room

We didn’t even claim it full time for two years there were still other classes in it

I saw it when we had one printer, when the coolest thing we could buy was a programmable robot kit for one of those cute lil guys you can program to move his cube around and we all had to share one

The goddamn budget request must have gone through as we all fucking left, because the next year they had not just the room permanently set aside, but the closet next door set up with TWO 3D printers and a laser cutter

I booped in and out over the next year too, mostly for curiosity (and to use the printers cuz the people now running the club were members when I’d been a founder and so long as none of us admitted I wasn’t paying tuition anymore it was fair game)

The last time I saw it, they had FOUR 3D printers, two laser cutters, three more craft machines I didn’t recognize, a working fume hood, and one guy had used club resources to build a working robot hand and was teaching it to pick locks

It was. It was amazing. It was a proper, actual piece of school infrastructure, providing benefits to the whole student body

And I was there when we just played Smash and helped each other with our homework
