So, I set about building an open-source ice tracker from DIY components that not only proved to be much, much cheaper but also much more capable than the commercial options. This consumed around 350 milliamperes while running at 5 volts for about 1.7 Hz, and longer swells, which range from about 0.08 microwatts.

Searching the interwebs, I found no shortage of leads about how to build a DIY seismometer. The problem is that the DIY seismometer designs I was seeing were large and ungainly contraptions. These range from about one cycle per second (1 hertz) down to a fraction of a cycle per second. I used a Raspberry Pi Model 3B+.

So when I decided to build a cheap DIY scintillating gamma spectrometer, it was the natural choice—although I didn’t realize I’d find myself navigating around teething problems of the sort that often affect a first-generation integrated circuit. This article appears in the July 2022 print issue as “DIY Gamma-Ray Spectroscopy.”.

Which seems plenty attractive to a range of companies and researchers. There are, researchers have discovered, a wide range of options to harvest enough microwatts to replace wearables’ batteries. volts for about 60 hours. In the future, DIY may not even be necessary. But solar is just the opening gambit.

November 2018 Hands On article, “DIY Pro Audio ” in IEEE Spectrum , and it convinced me it was possible, although I wanted to go beyond just a power amplifier to something more like my lamented Sansui. In commercial product development, an optimized microcontroller would be the way to go, but for my DIY project, a Pi was perfect.

If you want to design a battery pack on your own you may refer to the following book ( DIY Lithium Batteries: How to Build Your Own Battery Packs ) otherwise purchase a battery pack. Battery capacity Watt-hours = Amp -hrs X Volts . Bicycle A has a 36 Volts & 20 AH battery = 720 watt hours. Controller.
