Experiments with computing, electronics, and maker crafts.
In HP graphing calculators, between my beloved high school model (48GX) and the latest hotness (Prime) was the 50g. I thought I’d try to live without one but it actually has advantages over both of those models in programmability and data access (USB, SD card).
The Commodore PET was named after the Pet Rock fad of 1976.
The original Pet Rock sold 1 mil units at $4 each in 1976.
The trademark holder reissued the Pet Rock in 2012. It is still available on Amazon for $20.
You can get an original issue vintage pet rock on eBay for $75.
I thought the Super Mario Bros Game & Watch would be an overpriced toy that I put in a drawer. I was not prepared for how wrong I was. This is a perfect grab and go toy with multiple levels of engagement, a fidget toy during meetings and a casual game between meetings.
A short tutorial on opening the #c256foenix FMX case. It is quite serviceable but there are a few things to note. For starters, the panels on top provide access to the JTAG ports, DIP switches, and RTC battery with tiny Philips-head screws, if that’s all you need. (1/n)
