Power on Reset – Capacitor calculations
Why your homebrew Z80 sometimes refuses to start until you mash the reset button — and the simple RC circuit that fixes it. A maths-and-all walkthrough of power-on reset timing, with a Schmitt trigger thrown in to clean up the ramp and debounce the button.
Schmitt Trigger Oscillator
One Schmitt trigger, one resistor, one capacitor — and a working oscillator. A hands-on walkthrough of how hysteresis turns a humble RC circuit into a clean square wave, with the maths, the scope traces, and an honest take on its quirks.

A flashing cursor in a glass cabinet, an electronics kit on the kitchen table, and a paper-round-funded ZX81. The story of how a kid in 1970s South Africa fell hopelessly in love with computers — and the childhood dream still waiting on the workbench.
Why I hate Linux…
A lifelong Windows user gets shoved into Ubuntu by an Nvidia dev board — and discovers exactly why Linux still isn’t ready for the desktop. Failed VMs, missing drivers, and dependency hell, told with a sense of humour and an open mind.
