Exploring the World of Arduino Boards: From Basics to Powerhouses

Whether you’re a beginner or a seasoned engineer planning your next major design project, Arduino has you covered with a development board that’s right for you.   The Arduino Platform has long been the go-to location for amateurs and engineers, including myself, for rapid prototyping and design validation.   However, most of us do not venture beyond the popular Arduino development boards such as…

What's the thing that's probably wrong with this very cheap robot arm? I know the good ones start at like $10k so presumably it's something. https://www.amazon.com/LewanSoul-Robotic-Arduino-Software-Tutorial/dp/B074T6DPKX?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A1K1UK7O5KP6WQ&gQT=1

(clickable link) looks like your average cheap servo arm -- lots of pinch points and low weight capacity, but the real problem is the precision, or lack thereof. there's gonna be a lot of slop and backlash, which makes the already tricky project of manipulation basically impossible for anything more difficult than Brightly Colored Foam Cubes. fortunately the natural habitat of this type of arm is, like, "learn to robotics!" school projects where Brightly Colored Foam Cubes are the only kind of object in existence. (but keep in mind that i'm no big city mechanical engineer or anything.)

I'm gonna admit like, for a long time I've been pretty skeptical of MakerSpaces because there is that question of "Okay but is this a library's job?" And because so many makerspaces kind of end up as dead zones because only one librarian will actually know how to work the equipment in there and they'll end up leaving without training backup or a replacement. Like, they're lovely in concept, but in terms of execution my experience with them has been pretty rough because it would always be like:

Patron: How do I use the 3D printer?

Me, a Library Assistant who is on the Tech Desk because I am a warm body who knows the Dewey Decimal System and can help patrons with very basic tech questions: You leave a USB drive here and then it's not my problem! [Disclaimer: Not my actual words but pretty much the protocol]

But god, today I got to help work a makerspace where I actually knew 60% of what I was doing and I got to walk patrons through it and god, the sensation of talking someone through the basic functions of a machine, and then watching them help another patron with it is fucking euphoric. I get it now. I'm converted. I still don't know what the fuck is going on with Arduino but I'm into it, man. I feel like an artificer's apprentice in some kind of fantasy world.

Monty Jaggers McGraw:

I am writing new BASIC programs to demo at my VCF Southwest 2025 exhibit of my 1979 Tektronix 4054A color vector graphics computer.

One of the programs I am writing is a 1978-1979 Battlestar Galactica TV demo. That TV show had $500,000 of Tektronix vector graphics computers and test equipment and many screenshots of their green vector storage CRT displays - some stills - some animated. These computer graphics were generated on both 1975 4051 and 1976 4081 vector graphics computers - predecessors to my 4052 and 4054A computers (see first photo attached).

Miami Herald TV 1978 magazine interview with the Battlestar Galactica set designer indicated extras on the set stationed in front of the 4051 computers were playing games during filming to increase realism and were so absorbed they kept playing after the cut! (article page attached).

The 4051 and second generation 4052 were the same physical size and used the same CRT and same Display board, but the 4052 and 4054 computers replaced the 800KHz Motorola 6800 CPU with a custom four AMD2901 bit-slice CPU to create a 16-bit address and data bus ALU which emulated the 6800 opcodes and added hardware floating point opcodes to speed up these computers 10x over the Motorola 6800, doubled the BASIC ROM space to 64KB and doubled the RAM space to 64KB!

I created these vector bitmap graphics using a "3D CAD" picture I found on the web of the Battlestar Galactica (last attachment).

As far as I know - there was never any 4050 BASIC program to view bitmap pictures on any of the 4050 computers. The 1979 4014 vector graphics terminal had a grayscale bitmap mode in the Extended Graphics option board, but I have only found a couple of bitmap 4014 images on a single Tektronix demo tape cartridge.

My 4050 BASIC program to display bitmaps works on all 4050 series computers - with an optional Tektronix 4050R12 Fast Graphics/Graphics Enhancement ROM Pack. This ROM Pack speeds up displaying vector images (including vector dot images) 10x over using BASIC MOVE and DRAW commands.

The Battlestar Galactica bitmap image in R12 binary format is 332234 bytes - slightly larger than would fit on a DC300 quarter-inch tape cartridge in the internal tape drive of all three 4050 computers, but would have fit on a 3M DC600 tape cartridge with a capacity of 600KB - it would have been very slow to load.

I designed an Arduino board to emulate the Tektronix 4924 GPIB tape drive - with the help of my software developer. My GPIB Flash Drive board contains a MicroSD card with gigabytes of storage and the Flash Drive emulates a GPIB tape changer, storing all the files of a "tape" in a single directory. I have also attached to this post a photo of my GPIB Flash Drive.

I have recovered almost 100 Tektronix 4050 Tapes and posted the ones I think are the most interesting at this time on my github repository for Tektronix 4051/4052/4054 computers: https://github.com/mmcgraw74/Tektronix-4051-4052-4054-Program-Files I included Tektronix published MATH volumes 1, 2, and 3 and Electrical Engineering, but I don't think they have a lot of use today. I have in my collection but not recovered tapes on Project Management, Statistics, and over 100 more tapes from the very active user group, which Tektronix made collections and published abstracts in their newsletter and the newletter customer got the tape for free. Commercial software like CAD programs were likely encrypted to eliminate copying - since Tektronix 4050 BASIC included a SECRET command which would then encrypt the program file as it was recorded to tape and add a SECRET flag in the tape header that would signal to BASIC ROM when that file was accessed to decrypt the program when it was loaded into memory. One big limiter to the size of the program was RAM in the 4051 was limited to 32KB and the 4052 and 4054 were limited to 64KB of RAM, although Tek BASIC did include commands to allow program "chunks" to be overlayed as necessary. Tektronix used those commands in their 4050 System Tape which was shipped with every system and included a tutorial on many of their BASIC commands. The tutorial ran on the original 4051 with 8KB of memory, and if the program detected 16KB of memory it would APPEND larger program files to speed up the tutorial.

Hi Cats Tumblr People,

So I heard you like pics.

Please bear with me (AND TEACH ME) how Tumblr works/if I'm doing it wrong! I'm literally the "How do you do, fellow young people?" meme. Our Etsy is linked (unless I messed that up!) Right now it's bare (LOT of work and VERY old photos in the banner) but we'll be posting some cossies soon that are ready to retire. Some of our prices sadly will have to rise (we undercharge honestly for the amount of time put into them... we just LOVE making them). Anyway...

These are our original designs. We have taken inspiration from different productions, from the US tour to Gothenburg to Australia to Japan, less UK because it gets the most attention and we like COLOR! but this is all us. Our goal is to a) have characters be recognizable and b) make swing unitards in palates that could pass as at least 3 characters for emergency. When our rentals go out, swing unitards go with them, and ultimately it's the director who decides what makes the final cut (so a less yellow Demeter for example--but we LOVE that one).

If we ever do a production of Cats with Chaz, you'll notice one in Red, White, and some Black (but mostly Red and White, with fan ears, that is a design David created and is Chaz's FAVORITE design of all time. Any time he does a show, if we're hired, that costume goes. Usually Electra, but any ensemble/swing kitty and can cover for Sillabub or in a pinch Bombalurina. Yuka wore it at Interlakes before she did Victoria on the last US Tour! You might notice an Admetus in tans and GREEN undertones--that was my design he loved. We also did the purple twins (which was vetoed and I said, "Okay" then did it anyway because I knew he'd love it, which he did!), and REBA Gumbie Tap Suit was completely mine (everyone thought I was out of my MIND when I started making it! Even David! Then the shoulder pads came, and the belt, and tail, and BEDAZZLING!!! SO MANY RHINESTONES!!!!) Our Misto coat lights up but we still have a lot to learn about arduino since we'd eventually like to make it blink to music. The Misto coat is also created to fit a multitude of sizes, basically the theatre using their department for alterations since we make use of stretch fabric. I've known Bronson for almost as long as Chaz (he even designed my author website!!!) so when I saw him cast, I showed him his costume (a much, much browner/redder Gus than most see--I was serious about liking color) and let him choose between two coats. He said he wanted pants and we went, "NO! PANTLESS PRODUCTION!" because we thought he was joking! We didn't realize... HE REALLY WANTED PANTS!!!! SORRY BRONSON! So shout out to Wichita for making him pants! LOL!

There is a HUGE joke about Tumble thirsting for Tugger more than the girls so you'll notice that with the Tugger ABOUUUOUOUOUOUOUOUUUUUUUUUT THAT.

Hope that's of interest! And no, I'm not procrastinating on edits when my agent deadline is Sunday. Haha... ha... ha... ha... ha... Sera, if you're reading this I PROMISE I'M WORKING OKAY??? I DIDN'T KNOW WE GOT ON BROADWAYWORLD!!!

We also saw some comments about casting in general and some confusion/questions about different dancers doing different parts (Alonzo vs Plato). Would anyone be interested in learning more about the casting process in general and things that directors/choreographers need to take into consideration? Please note, I will not discuss ANY performers we work with. Ever. All are extraordinary and these are tough calls that aren't easy to make and based on other factors, including the ensemble at large, and sometimes huge changes are made.

Not that good though- still a beginner!

Type of cg:

I’m looking for more of a amab , if you are afab tho I won’t complain, I just have daddy issues 🤩 pls never sexualise me. I want someone comforting and someone WHO HAS A NICE NIGHTY NIGHT STORY VOICE WHY CANT I FIND ANYONE WITH A GOOD STORY READING VOICE?! As in you have to read stories well, not just ur voice sound (so like expressions in vocals) [guys that last part was /hj] Anyways also someone who supports me through thick and thin no matter what, dealing with my meltdowns because I will have them guaranteed, also someone who makes sure I do basic human things? I swear no one checks up like “hey! You’ve drunken water yet?” When I ask them to in the ppl ik

Please respect me and know I am NOT LOOKING FOR ANYTHING ROMANTIC I HAVE A GIRLFRIEND IRL

I've been doing something cool lately.

It's called Pokemon Automation and it's where I do nothing and let a program + arduino run Dynamax adventures for me the entire day. Basically Shiny hunting the max lair for me Automatically.

The bot has better luck than I do.

…hand over your knowledge. PRONTO.

[taviluvsu]

Say Hi to TAVI!

Tavi (they/xe) is a robot oc I made a while back. I want to have more interaction with others and develop them as a character.

Some basic information:

they/xe

inspired by Macintosh and Arduino softtware

selective mutism, mostly speaks in “mrrows..”

mostly uses hand gestures to communicate

LED screen head hows a lot of emotions

Feel free to ask Tavi anything! I wanna doodle em more and make friends with similar interests as well!

[myfootyrthroat]

We're looking at making/buying a non-cloud doorbell camera for the house. I'm not afraid of working with an Arduino/Rasp Pi, etc if necessary, but obviously if I could just buy something affordably, I'd rather do that. Basically something where someone could ring it and it would ping people on the local wifi (or maybe through an API like Adafruit IO, but not Amazon, etc). Anyone have any recs?

(@robustcornhusk this seems especially up your alley)

[ziekkfreak2-0]

On one hand, I hate my robotics teacher for teaching us the same lesson on python loops we've been learning for half the damn school year, then expecting us to make an innovative robot in 3 weeks when arduino is based on C++.

I was gonna counter that with something else, but as I wrote it I realized just how stupid it actually is. Fuck it. Venting time.

NO CUZ I CAN'T UNDERSTAND THIS GUY. WDYM "Programming's easy! You learn the basics, and from there you make your own solutions." ??? That's not verbatim but. STILL.

I'll give him a bit of credit, he taught us the basics of arduino. The proper syntax, loops, variables, functions, motor control, sensors, etc. But for god's sake, that limited pool of knowledge can only get you enough to make a mini car! It would've been nice to learn about fading LEDs, integer overflow, pointers vs the actual value in a variable, OR EVEN WHAT DOCUMENTATION IS. YEAH. DOCUMENTATION. THE LITERAL OFFICIAL EXPLANATION FOR KEY FEATURES IN PROGRAMMING LANGUAGES.

But suddenly its OUR fault our code doesn't work because "I taught you the basics. If you don't understand, that means you're not listening during my classes." MAYBE IF YOU STOPPED TEACHING US WHAT A FUCKING FOR LOOP IS, WE'D HAVE A REASON TO LISTEN. Majority of my understanding of robotics are a product of self study and receiving help from my family and their long list of IT contacts.

Not only that, HE is the one that approves of our robotics projects. If YOUR students can't complete the project YOU personally approved of, isn't that an error on your part? You should know what your students are capable of making. You should know because they should only know WHAT YOU TEACH THEM. So surprise surprise when your students feel like they're forced to hire people to do their projects, all because of your failure to teach them the skills they needed to do it themselves.

The only people getting a passing grade in this class are gonna be those that are either rich or have a lot of contacts. What a fucking joke.

And don't be mistaken, this is NOT the complaint of someone who doesn't understand programming. I consistently get 90% and above on his exams and do coding for fun. I'm complaining on behalf of my classmates who weren't as lucky as me, in that I have way more people to ask help from.

"100% working by this week" my ass. Actually teach us something relevant for once.
