💽❤️📶 My MiniDisc player now has built-in Bluetooth, for streaming to AirPods Pro... time to blast some Linkin Park like it's 2001, but without wires🤘

Making the most out of the limited space inside...
How to improve this circuit? Generates single 3~4s pulse after being powered on (3.3V). Can't get any bigger in size, should discharge cap. immediately after shutdown so pulse length is consistent every time (even after short power-down time), and ideally use LM393 as well. Go!

ideally it would use a smaller and less bulky cap, but I'm afraid that the resistor between VCC and inverting input would need grow too large (already 470k) to achieve desired pulse length... perhaps there's a better architecture I don't know about?
Does anybody in Berlin have a Pololu U1V11F3 boost converter (or similar tiny converter, 3.3V out) lying around that I could pick up super-short-notice? 🤖

Needs to boost from 1.2~1.5V to 3.3V, small output current < 50 mA, and have a tiny footprint / height. The Pololu's 12 x 15 x 3 mm is juuuust barely small enough 😉
On the question: "Do I really need to provide a manufacturing drawing, or is a CAD model enough?" Here's a 1D example of why in some cases, having a drawing *does* matter. Based on a conversation with @timonsku xitter.cf/timonsku/status/133209…

The whole thing gets more complicated if you add additional requirements. Hole diameter tolerance, hole roundness, straightness of the bar... not to mention extending the example to 2D and 3D!

Another part has arrived! This time, it violates another requirement of ② (overall length), but is still just as usable for ① thanks to the relaxed tolerances for functionally irrelevant dimensions 🎉
