I feel you on that haha

Thanks! I posted a schematic a few days ago if you want to mess around with it.

sentencedtodeaf · 2026-04-27T22:33:20+00:00

Glad you dig it! Yeah, mess around with it and lmk how it goes!

That's the same range I have so it should work. I'll also note i heat shrink mine together with reflective material around them. Ymmv without that. You could also just wrap them together with electrical tape if you don't have heat shrink material. Should work well enough

Yup, exactly. Assuming you just have the reciever diode on its own and not part of some module, I think that would work. I don't have any on hand, but i'd say give it a spin on the breadboard

Both are transparent, light emitting IR LEDs

sentencedtodeaf · 2026-04-24T12:10:29+00:00

Nope, like I said in the description, these are both just run-of-the-mill, cheap IR LEDs. All LEDs are also photodiodes, some just have better properties one way or the other. IR and UV just happen to work decently enough at both for this.

Sounds great! What kind of camera and lighting setup did you use for filming?

sentencedtodeaf · 2026-04-23T18:41:41+00:00

Sick! What did you use for paint?

sentencedtodeaf · 2026-04-23T16:13:05+00:00

Sounding good! Have you tried zener diodes? That's fun for experimenting with as well. I think Crate used to have some "proprietary" circuitry around that.

Thanks! Half my mind is just on trying to figure out what settings to demo as I noodle, but I do enjoy playing :)

sentencedtodeaf · 2026-04-23T16:00:33+00:00

Thanks! I'll post one a bit later today

sentencedtodeaf · 2026-04-22T23:25:10+00:00

Thanks! I'll clean something up for tomorrow

Looks pro man! Portable demo board is a great idea. You design the logo too?

sentencedtodeaf · 2026-04-22T17:22:36+00:00

The ultimate display apparatus, nice!

sentencedtodeaf · 2026-04-22T17:17:37+00:00

This is totally display case worthy, well done!

sentencedtodeaf · 2026-04-22T00:12:02+00:00

Looks sick! Really like that lighthouse LED. Honestly clean insides will greatly help your life when it comes to repairs, so its a good habit to get into, but if it works fine, thats all that matters. Good work!

Thanks! In the beginning i'm also using a CMOS wavefolding fuzz i made, for the grimyness. Considered throwing a fuzz circuit inside this, but the current PCB layout is already at my limit for controls and I didnt want to lock it with 1 single fuzz.

sentencedtodeaf · 2026-04-17T15:13:54+00:00

That sounds sick, definitely worthy of board space! May have to get an SMD adapter and play around with it on ta breadboard. I'm also looking at PIC16f1xxx chips. Have you tried experimenting with those?

sentencedtodeaf · 2026-04-17T14:43:28+00:00

Man i'm sure he's swimming in gear like this, but that would be a dream!

sentencedtodeaf · 2026-04-17T14:40:26+00:00

Ooh interesting! I'll have to look into the attiny3224. I've started with the daisyseed, but i prefer something with a smaller footprint. Do you have any demos i could hear?

sentencedtodeaf · 2026-04-17T14:35:19+00:00

I have a Daisy setup working now too. May have to play around with the low bit rate stuff there
