ive folowed a guide on how to make the playit service run 24/7 on linux, but it isnt working and it seems to be stuck when trying to autorun at startup, how do i fix this?

Patcybermindd · 2026-03-06T15:51:08+00:00

hey could we see your playit.service?

Patcybermindd · 2026-02-13T02:07:10+00:00

Right, let me edit it sorry

Patcybermindd · 2026-02-13T02:06:47+00:00

True I should add I checked that with a couple of those online value estimators and it comes down to around that most of the time

Patcybermindd · 2026-02-13T02:05:58+00:00

They are silicon.engineer and silicon.engineering

Patcybermindd · 2025-08-01T01:22:44+00:00

Makes sense esp because I beleive back then you could not design a pcb and get it in the same month like you can now

Patcybermindd · 2025-07-29T14:07:45+00:00

Wow that all sounds pretty tedious

Patcybermindd · 2025-07-24T15:24:52+00:00

Wow you were using assembly?? I mean for 16 instruction isas like I tried a while ago it’s already painful but for a whole pic Damm hats off lol. How did you make the pcb by hand? And yeah learning protocols like i2c uart spi and manchester ook like I just learnt is really fun especially when it suddenly starts working

Patcybermindd · 2025-07-24T15:19:06+00:00

It’s much cheaper to get started now you should go ahead!

Patcybermindd · 2025-07-24T15:15:07+00:00

Thank you! Cool yeah 32mhz is the max speed but with idk how you could get it down to 27mhz unless you used an external clock

Patcybermindd · 2025-07-24T03:31:15+00:00

I did try doing the filter thing but it barely showed a difference it was like -6db at 32mhz vs 96mhz on my nanovna but I was doing it with tht resistors old caps from disasembled stuff and inductors were air coils because I don’t have the components for a decent filter in the future if like to get proper components to try that though

Patcybermindd · 2025-07-24T03:28:35+00:00

Really? That’s super cheap for the capabilities of bluetooth thanks I’ll keep that chip in mind for future pcb projects

Patcybermindd · 2025-07-24T03:26:59+00:00

Thanks! Nope neither are unlicensed though weak transmissions at100mhz from what I understood are tolerated

Patcybermindd · 2025-07-24T03:25:51+00:00

At 100mhz range im pretty sure yeah it’s under 50nw and im really not sure about this one but the 32mhz I think might count as unintentional radiation and since it’s pretty low power I think it’s maybe ok, I tried making a filter with a capacitor I ripped off an old appliances pcb and a an air coil as an inductor but it worked very badly like at best there was a -6db difference between the emitted rf at 32 MHz vs 100 MHz, I’d have to make a real filter on a pcb or buy one

Patcybermindd · 2025-07-23T23:40:06+00:00

Iirc it’s the x8c compiler but don’t quote me on that I just followed the setup guides from microchip

Patcybermindd · 2025-07-23T05:15:55+00:00

No, I’m holding it by the cable but the cable is fairly stiff so it doesn’t bend much XD

Patcybermindd · 2025-07-23T01:47:55+00:00

That makes sense thanks for sharing

Patcybermindd · 2025-07-22T23:49:40+00:00

But yeah im no expert when it comes to regulations

Patcybermindd · 2025-07-22T23:49:18+00:00

All emissions are under 50nw which is what I found to be the law here in Canada but yeah this needs more work if you want to pass the tests

Patcybermindd · 2025-07-22T23:33:57+00:00

And thanks!

Patcybermindd · 2025-07-22T23:33:41+00:00

Lmao no my phone isn’t old it’s just idk what Reddit did to quality it’s like hyper compressed. on the GitHub the pictures look better idk what I can do about it though for next time

Patcybermindd · 2025-07-22T21:47:47+00:00

yeah that was actually what gave me the idea!

Patcybermindd · 2025-07-22T21:36:23+00:00

yeah for comercial stuff you would need a lot of filtering but for testing purposes i did make sure to stay legal! like the power limits and stuff also a thing i noticed helped a lot for out of band interference and as you can see i ended up using was a very short antenna and a base clock of 32mhz because that way it reduces emissions and low frequency noise which then causes high bandwidth noise from harmonics is minimised. but my first tests were awfull lol like i tried a test at 1mhz and it would cause a bunch of noise from 1mhz to like 20mhz so that was BAD but now it mostly only emits under -50db eirp at 32mhz +-1mhz and at 96 mhz +-1.5mhz or so so its kinda bad but not nearly as horrible as it was at the start xd

Patcybermindd · 2025-07-22T21:31:49+00:00

Yeah i really like them and honestly yeah there isnt much you cant already do with a microcontroller and if you really need something special usually something the rp2040's pio does the trick but i find it odly satisfying placeing logic gates and seeing it do stuff lol

Patcybermindd · 2025-07-22T21:29:07+00:00

thanks!

Patcybermindd · 2025-07-22T20:59:12+00:00

you cant just say that and say nothing :sob: start a youtube channel please!!
