Hobbyist Electronics Starter Kit
What basic equipment will you need if you want to get started with hobbyist electronics? It’s possible to put together a useful hobbyist electronics toolbox relatively cheaply with a few key tools. Whether you’re building FPV drones, repairing retro computers or hacking Arduinos and Raspberry Pi’s, a basic soldering kit and a multimeter can go a long way. For more complex projects you might also need a bench power supply and test equipment such as an oscilloscope, but you don’t have to spend a fortune to build your own mini electronics lab.
The Epson HX-20 - A Contrarian's View

Getting data out of an old computer often means reaching for (or making up) a serial cable. Here’s an example, transferring files from a Tatung Einstein to a Windows 10 computer using a USB to Serial adapter and a custom cable.

A New 8-Bit Computer - Cerberus
Much of the attraction of retro computing is the chance to understand how a machine really works. For some, that’s about building a thorough knowledge of the library of games and tools that came with a classic computer. For others, it’s about developing new software for retro consoles. For a dedicated few, it evolves into the desire to make your own device, to your own unique design. What better way to understand how computers work than to put together a complete working system from individual parts?

Reviving the Enterprise 128K
Today’s adventure is a (relatively straightforward) revival of the Enterprise 128K that has been lurking in my loft, and a review of the Wavlink Composite Video adaptor. The two products have nearly forty years between them, but they work well together to bring retro computing to the big (ish) screen.
