Upgrading an M4 Pro Mac mini's storage for half the price
A few months ago, I upgraded my M4 Mac mini from 1 to 2 TB of internal storage, using a then-$269 DIY upgrade kit from ExpandMacMini. At the time, there was no option for upgrading the M4 Pro Mac mini, despite it also using a user-replaceable, socketed storage drive. But the folks at M4-SSD reached out and asked if…

Pure Silicon Demo Coding: No CPU, No Memory, Just 4k Gates
In addition to the VGA donut , I submitted two other entries in the Tiny Tapeout 8 demo competition , where you submit a "tiny" ASIC design (room for about 4000 logic gates) that outputs 2-bit RGB to a VGA port and 1-bit audio to a speaker. One was a an old school C64/Amiga intro type of thing, and the other was a…

How big a solar battery do I need to store all my home's electricity?
I have a modest set of solar panels on an entirely ordinary house in suburban London. On average they generate about 3,800kWh per year. We also use about 3,800kWh of electricity each year. Obviously, we can't use all the power produced over summer and we need to buy power in winter. So here's my question: How big a…
