Mainly making things that make music.

Laying out any project featuring a USART serial port.

@DemmonShadowp @DavidBGrys The Germany one having already slapped CE marking down, specifically lol.

[Tom Fleet @tomfleet]

@DemmonShadowp @DavidBGrys I think these are satire.

Good satire, but nonetheless.

@icanc4 You've got a VCSEL dot pattern projector for under 3 bucks?!

Everyone is a DJ until there's one of these in front of them.

次のDJの人、機材の中にIHコンロあってワクワクしてる

[Tom Fleet @tomfleet]

The XDJ sitting visible in the background is top tier trolling.

Well done, ha.

@QVHenkel @davideasnaghi Looks a good match to me lol

[Tom Fleet @tomfleet]

don't shout at me, I just have a large pile of such boards, and am spendthrift.

[Tom Fleet @tomfleet]

so, for reasons I can't quite recall (I think I was bored), it turns out you can take something like the esp-idf build process, and split the build out across say, a set of arm rockchip nodes with pretty little effort.

practical? maybe not for esp-idf stuff, but it's a fun toy!

[Tom Fleet @tomfleet]

Very fun - I had a similar idea, but stopped at lightscribe discs (for some reason)

this project using stock writable CDR media is a huge huge advantage over the pricier LS discs!

AKAI goes Open Source?! 👀

AKAI claps back to Behringer announcement of their open source firmware in their Kick Product.

[Tom Fleet @tomfleet]

@MikeStillAwake Funny you should say that!

They say imitation is the most sincere form of flattery.

(I mean that's not what legal are saying but lol, fair play Behringer. Fair play)

[Tom Fleet @tomfleet]

@hansfbaier Oh it's all getting very interesting!

[Tom Fleet @tomfleet]

@MakeAugusta You know, that's the first time I've heard the full statement.

[Tom Fleet @tomfleet]

@MattGialich I've been saying this for many years!

Gotta love Kapton tape. It's rare, but sometimes hot-melt glue *isn't* the answer! #led #wearable #not-the-day-job(yet)

[Tom Fleet @tomfleet]

@_MG_ no i can see how that would be possible.

i'm actually very curious, can you see your potting compounds outgassing (moreso their breakdown products) over time?

or did you have to spring for non acetic RTVs/compounds?

that's if you are using them anywhere 👀

[Tom Fleet @tomfleet]

Interesting timing, because, see, this is maybe the only really viable option for a universal "tamper detection" system.

1/16 You can see inside a circuit board without cutting it open.

Send a fast step into a USB port and listen for the echoes. Every bump is a spot where the layout changes, and its delay says where.

That's TDR, radar for PCBs. I simulated it on a real Raspberry Pi board 🧵

[Tom Fleet @tomfleet]

@_MG_ that's a very good point actually, the entire premise of cap sensing on gpio is down to being able to sense this sort of effect - I imagine this actually could be whipped up as a PIO blob on something like the RP23xx right, ideally as some input to the secure bootloader process?

[Tom Fleet @tomfleet]

@_MG_ I saw a paper that was experimenting with doing it at the board level, I cant recall how but I imagine you can characterize some elements with a small FPGA sitting on the relevant wires right.

do a bit of "analog boundary scan" on boot, check all your freq's still match?

[Tom Fleet @tomfleet]

@MakeAugusta is this not copper defined? i misread it perhaps.
