And it finally works, after much head-scrstching,.many (many!) dry joints, a few broken wires and having to switch GPIOs because #tinyusb seemed to want to hold on to gpio1+2 despite my best efforts, my #MGT #SamCoupe USB-HID mouse adaptor prototype (based loosely on the #RP2040Mouse project) is working

#ReteoComputing #RP2040 #RaspberryPiPico

Couldn't understand why the rp2040-based usb mouse interface I was building for the #SamCoupe was outputting random keypresses. Figured there had to be some issue with the RDMSel line because the way I've designed the interface there should be no way keypresses could happen other than cursors.

After much head scratching and adding filtering caps etc I went back to basics and did continuity testing. Far simpler than I thought.

#breaking from the BBC...

In other news, Andrew Mountbatten says "I could never work in a women's refuge" and Warwick Davis says "I could never enter the World's Tallest Man competition"

Think someone didn't pay enough attention in Chemistry.

Could be potentially fatal...

Beaters on our #Shark upright decided to give up the ghost while I was vacuuming today. I thought maybe the belt had slipped so took it all to bits, only to find the motor had pretty-much burnt itself out. Realised it was still within the 5-year warranty (by 3 months lol!) so rang their support line, incredibly helpful guy asked me to show him the part that wasn't working on a video call, I think he was a bit taken aback when I showed him this 😂😂

They're sending a new base nozzle section tho.

Wow. Just wow. I've been staring at a layout of this on a screen for 2 hours a day for about 2 months. I had absolutely no handle on quite how tiny it is.

Now I'm just scared to plug it in.

Who reckons this cabin filter was checked at my wife's car's last full service in December?

Bear in mind it's probably only done about 500 miles since then.
