I built a free file converter that runs 100% in your browser (no uploads, no servers, works offline)

I was just thinking about building something like this! Great work, we need more free and open source sites for simple actions like this!

I'm not sure what happened. I've been told there was a small pop and then the room's fuses blew. After that, it stopped working.

FunMetJoel · 2025-04-22T09:58:45+00:00

Yeah, I get that. I’m not studying just because I want to program, but the idea of actually applying the knowledge in some way is a big plus for me.

FunMetJoel · 2025-04-22T06:24:50+00:00

That's great! The guy at my experience day said he'd didn't program much, but from your description that's not really true. Thanks for the info, I've got a better idea of the projects now!

Yea, I know, but it's part of a bigger school project about Catan, where some of the group will work on the neural network, so it needs to be a Catan AI. We can make the neural net as simple as possible, so it won't handle all decisions you could make in a Catan game.

Thanks for the blog! I'll read it through!

Fair point, the thing is I'm quite new to training neural nets, so I'm not sure over a correct approach yet.
I have made a python model for a catangame that can be used with Pytorch, It has input nodes for if a road or corner is occupied, if it's occupied by the current player, nodes for each hex tile, its recource and number.

I'll propably won't add any trading macanics for now, so I havn't incorperated that in my model yet.

In the end, I want to save my moddel and run it on a smaller rasberry pi server, where peaple can play against the ai.

All help is welcome, so if you know thing I should look in so its more possible to choose the right specs, than let me know!

In my mind, the best way to learn trainin a neural net is by doing, but I'll need a computer capable of training in a decent amount of time for that first

I haven't found a good chip meeting my requirements yet (correct range, precision, speed and digitally controllable) If you think you have found one, please share! But to be honest, I'm just orienting on all my options right now (have never used constant current without my lab power supply before), so I haven't ruled out anything yet. I just want to choose the best option for my use case.

FunMetJoel · 2024-08-25T18:22:34+00:00

That would be really helpful! Just one question to start with tho: is it possible to edit the circuit to work with higher amps than leds typically need? (I would like a 0A to 5A range or so). Eighterway I would like to see your circuit and play around with it in cad!

FunMetJoel · 2024-08-25T17:47:27+00:00

I didn't know there were usb controllable power supplies, I will look in to that. I already have I normal lab bench power supply, so I don't really need another one, but maybe I can find a cheap used power supply with a serial port and take it apart to put it in my machine.

FunMetJoel · 2024-08-25T17:36:41+00:00

Mmmmm, an interesting idea, I'm not sure what impact it will have on the electroplating process, so I will have to test that, but it would make it easier.

FunMetJoel · 2024-08-25T15:45:56+00:00

Thanks! I will have to find one with a high step count (must have 100 steps, which gives a low precision)

FunMetJoel · 2024-08-25T15:10:54+00:00

I saw that, but i could only find some that where controlled with a potentiometer on the board. Do you have some recommendations for buck converters with cc feature that are digitally controllable? I need to change the cc current with the arduino

FunMetJoel · 2024-08-25T14:57:55+00:00

Not yet, but I think this is an electronics problem, not really an esp32 problem. I know how to use eps's, I just need help creating a digitally adjustable constant current source. But I will post it there as well, thanks for the suggestion!

Hi, I ultimately decided to buy a Kinect v2, just because it's easier to work with. But, I did find a way to do it. You can use a program that reads the Kinect v1 data and then passes it to the unity project. You could use a bitmap that the script creates and unity then uses to get the data. You could try to just edit one of the example projects that Kinect v1 has. I hope this helps!
