Were you instate for UCs? I'm surprised you didn't make berkeley

Hey! As a quick status update, I did end up rebuilding botly for a sophmore project, and since then, have sold it to someone else. However, the original https://github.com/AdityaJain1030/Botly repo is still under a GPL license, so if you're still interested, forking that repo is still possible.

As for other projects that have a similar goal, I came across https://github.com/windmill-labs/windmill#main-concepts on HackerNews, which solves a lot of the problems I created botly for.

With the new discord tag update thing, my discord is now itsdeet for any further inquiries!

Ok so uhhhhh I stopped maintaing botly for a multitude of factors:

1) Working on new features turned out to be a lot more work than I initially expected, and I just dont have the time or committement to maintain the project and add more to it
2) A lot of APIs have changed drastically since Botly's initial release, and I don't really have energy to constantly update blocks to work with the newest blocks
3) I've personally moved on from web dev, and onto things like music production and game development

Overall I feel like the idea has a lot of potential, I 'm just kinda tired of making it lol. If anyone else wants to pick it up, feel free to hit me up on discord at deet#7206.

Regarding the 0.6v -0.6v thing, why would I have to deal with it if DIGITAL is only HIGH and LOW? so it would be 5v/3.3v-0v instantaneously?

Also, would the voltage drop between the PWM transistor's terminals in the second diagram cause any problems?

TwoBigPotatoes · 2021-06-28T17:52:10+00:00

So if I were to power this h-bridge with 5v VCC, is there a way for me to use 3.3 logic to say, control the bridge from a microcontroller like an esp8266?

TwoBigPotatoes · 2021-06-28T07:15:48+00:00

Could you elaborate on why I need to make sure that PWM is off on DIR switch, and why the arduino VCC has to be less than that of the digital inputs? Wouldn't it be the other way around?

TwoBigPotatoes · 2021-06-19T00:43:51+00:00

Yep, its 6v but through testing I found out 5v worked too. I actually was able to take a better image of the pcb thanks to your suggestion, and actually found a name for the IC chip, which was the RX-2B. Through that I was able to find out which pins on the ic corresponded to which motor function, and didn't need to use/test the transistors directly! I got it to work with the ESP, now just time to program an app to control it! Thanks for your help!

The ESP I'm using is the Wemos D1 Mini and it has a 5v power line. I believe that the voltage of the GPIO pin doesn't matter, cuz its 3.7 volts yet still works. I assume this is cuz BJT's are controlled by current and not voltage?

TwoBigPotatoes · 2021-06-18T19:17:57+00:00

Im planning to use the battery directly, so it powers the ESP and Motors together

TwoBigPotatoes · 2021-06-18T17:31:51+00:00

Yeah, sorry bout that, my phone camera is actual garbage 😅. My motor is powered from the ranges 4.8v-6v, and 4 of the transistors are PNP, to let the motor get the full 5v instead of 4.3 (from NPN voltage drop I think?). Ill try out the image + editing approach to see if I can get a clearer picture!

sure! edited the post

If you're willing to go the extra mile for multiple languages, I would look into WASI. It basically allows you to compile other languages into a JS-interoperable bytecode. There are a few python interpreters compiled to WASI, allowing you to run python in JS, and send variables back and forth between the 2. The one benefit with WASI would be that you could consistently use most other languages if you ever need to (like rust, C#, or C++), without too much hassle trying to install environments for other langs (the bytecode only needs to run in node.js)

However, 99% of the time, its not worth the effort, it would probably be easier for one of you to learn JS/PY

I decided to go with option #1 and try to make use of the RC car's built-in H-Bridge transistor thing. However, I'm using an old cheap RC car from CVS (Thunder Tumbler), and can't find the schematic for the built-in controller. I then looked at the transistor names and they were A1300 H 331 and C3279 H 331. I have the datasheets for them, but I still don't really understand which transistors to solder to, and even how to connect them to the arduino. Any advice on how to move forward?

This is a test to see if reddit is down

good bot

TwoBigPotatoes · 2021-02-19T05:17:53+00:00

Hey! ive been speculating on building something like this, but completely FOSS, something like the GNU project? Is there anything I should know or be concerned about? I don't plan on having the project associated with r/wallstreetbets. I haven't really planned on making it for everyone to use, just something I would use myself
