Needed a little PWM controller at 2am and instead of slapping in an attiny i chose to deadbug up a 555 timer :>
works great from 5% to 95%

My ‘is this atmega2560 pre-programmed’ question has been answered by a blank screen on power up. Quick! Break out the attiny programmer and let’s blow some fuses.

Oh yeah, about that pause detection.
The full Arduino is overkill but the attiny doesn't have hardware serial which is needed for snappy pause response from the Bluetooth module.
Luckily there's a gpio pin on the module that pauses if you short it to ground.
I'll need a PCB for this. 🤔

I have had some ferrite cores arrive (they're apparently way better) and I've sussed the logic.
When you press reset, it'll query the BT module via serial, and wait for something to play. It'll immediately pause it and enter a ready state.
i'll port it all down to an attiny at the weekend. 🙂

The PCB is little more than a breakout board for the attiny and hall effect sensor but should definitely do the job.
Into the tub it goes. ☺️

Me in December: Imma make a quick PCB with an USB to power an RPI, so simple, I'm a genius.
Me in February: So I have a level shifter, a buffer, need to integrate an ATTINY chip and also a GPIO extender. 🤪

I think space RAM (and any circuitry) would be expensive.
(I’ve not worked with “proper computers” in space, but ATTiny equivalents are ~20x in price. They produce the space-worthy ones by taking 20 off the production line and bombarding them with ionising radiation until they have a winner…)

Well, the RPI boots too slow for my taste, so I ended up shoving an ATTiny chip beside it to drive some hardware while the main SoC is booting up 🤪

ATTiny, normally powered off. Pressing a button connects and latches power, the chip plays sample from Flash (yes + no samples should pretty much fit within the small flash) and then the chip unlatches power to go back to zero power draw.
ATtiny3216 should do the job.

Die Komplexität ist skalierbar. Statt eines ESP32 kann man auch einen 8 Bit ATTiny nehmen oder vergleichbare Microcontroller. Alternativ kann man auch eine Komperatorschaltung nur mit diskreten Bauteilen machen, was Du möchtest.
