You could join the resource industry, there's a labor shortage and there's all sort of vocational training. Some jobs require minimal training others more but you can be up and running in as little as 3 months for…
You can contract the pcb work out on fiver and have the boards made at one of the Chinese board houses nowdays. I think I've seen people on Fiverr that provide turn key solutions you pay for it in turnaround spread and…
Yea, the difference is in capex cost and capabilities so the best you'll get is the ground temperature. Ideally you put a ground source heat pump but the energy needed to run it is high, COP for a ground source heat…
The tubes are called earth tubes or ground-earth heat exchangers. If you look for geothermal heating you'll end up getting the wrong information, mostly for ground source heat pumps. The earth tubes aren't strictly…
Dam, didn't think I'd see another mining person on hackernews. Exploration geology that far down is wild. Was it core sampling all the way from grade or only in mineralized zones?
Make a shield for an Arduino, kicad has a template for the dimensions and positioning of the headers. A fun one is to make your own Arduino board, take the design for the uno and layout your own version and see if it…
10/10 agree for Canadians McMaster Carr is a godsend. Can order random stock material and have it tomorrow and have a certificate telling me exactly what stuff is with a nice cad model. Their search is the best though,…
Energy input is the other. It takes at minimum the combustion energy to reconfigure the molecules but most of the processes happen at high temperature and pressures which takes energy to do.
Bit flip probability is inversely proportional to density of the storage media so denser might have you run into issues. Also theres no point on building a recorder that's 10x larger than what you need if you're going…
The worst is when the other guys think you're crazy because they're not suffering the same problems because either the smps they have had a soft start or they overspeced the living crap out of their input stage. I gave…
Real world effects of parasitics are underated. Found out the hard way that there's a whole lot of pain involved with hot plugging a battery into a board when there's a modular switch mode power supply onboard. Oh, you…
Until the REM is up and running, then truly never need to go outdoors.
