Any recommendation for DIY apps or software?

I'm after something that helps plan cutting lists to minimise waste but I thought I'd also ask for general recommendation and honest reviews.

Hey /diy/ computer fag here, I got an assignment a few months ago to work on about 3 dozen workstations. At the time I had a coworker who lent me a power drill that was sensitive enough or whatever that I could drill a screw straight into the motherboard mounts and it didn't damage the board. I spaced on it at the time and now the guy is gone, can anyone help me identify what this was? Budget isn't really an issue I just don't even know how to look for an electronics sensitive power drill

Picture unrelated, also ask a computer networking monkey anything

Its a really great time, and /diy/ has garnered the reputation of >no fans, so I'd really like the see the board come and support the team.
>OK, I'm intrigued what do I do?

Can I use a regular old clothes iron to seam carpet? I'm trying to replace a small piece of carpet for as cheap as possible.

motherfuck /diy/. ive done it twice and its still shit. has anyone else worked with this frustrating garbage? i dont know if its the type i used, or im still fucking it up else where.

this shit sets in the span of exactly 8-10 seconds. before that its like trying to lay dish soap on someones face and get it to build up, after that 8-10 second window, its done and if you touch it anymore itll clump and rip clean off the person.

ive tried it with more water vs. less it just delays setting but dosent give me that window to work with it. the videos ive seen they are grabbing it by the handfuls and just laying it on like spackle, i must be missing something god damn youtube aint telling me, anyone else have remotely the idea of what the hell im talking about?

Hey /diy/kes, I broke my phone and the connections are severed, doesn't turn on. Is there anything I can do with it that isn't wasteful and kind of cool?

I'm interested in casting silver using the lost wax process. However, I've read that an investment casting table is needed to make the silver take to the mold properly. A casting table starts at ~$800, so I want to make my own. I heard that one can be made with a vacuum pump, some fittings, and some basic welding. Does anyone know about this? I've found a lot of vague guides to making one but not yet one with a parts list, steps, etc.

I have a whole-house fan and as the days get colder I find that it's a bit too strong even on the "low" setting. So, I would like to add a timer-like device to the circuit that would do something like a duty cycle: "5 minutes on, 10 minutes off, 5 minutes on, 10 minutes off" preferably with the ability to adjust the proportion of on time vs off time; however all the "timer" in-wall devices I can find are like... programmable per-day kind of devices instead of interval-based.

Does anyone know what the magic search term is for duty-cycle/interval-based timer devices? Or if they even exist in the first place...
