New Timepiece for a Classic Mac – Part 2
I previously updated an open-source project implementing a pin-compatible real-time clock replacement for the Mac SE/30. At the time I considered using the universal serial interface (USI) peripheral built into the Microchip ATTiny85 microcontroller but dismissed it. This post picks up where I left off, making use of the USI module to offload the processing…

Private LTE with LimeSDR and srsRAN – Part 1 (Software)
Working with IoT devices it’s often useful during development to have access to a cellular network simulator or private mobile network. While the setups were previously prohibitively expensive for small time users such as myself. The reduction in cost of high performance software defined radios, combined development of open-source network stacks brings them into reach…
