Open Hardware: Raspberry Pi, XBee, and CPUs

Made in Kenya
So it’s more than a little surprising to be writing an offshoring announcement. Starting this week, we’ll be building Raspberry Pi Pico products for the African market at Gearbox Europlacer in Nairobi, part of the Gearbox ecosystem. Roger is in Kenya now, helping the team there bring up the manufacturing process, and we’re expecting him to return with a freshly baked batch of “Made in Kenya” Picos by the end of the week.

Minimalist 6502 System Uses A CPU And Not Much Else
A central processing unit, or CPU, is the heart of any computer system. But it’s definitely not the only part: you also need RAM, ROM and at least some peripherals to turn it into a complete system that can actually do something useful. Modern microcontrollers typically have some or all of these functions integrated into a single chip, but classic CPUs don’t: they were meant to be placed on motherboards along with dozens of other chips. That’s why [c0pperdragon]’s latest project, the SingleBreadboardComputer, is such an amazing design: assisting its 6502 CPU are just four companion chips.

Home-Built CPU Runs With Home-Built Toolchain
A few years ago [Takaya Saeki] and fellow students of the University of Tokyo, were given a very limited instruction during their ‘CPU exercise’ class, along the lines of:
