Well, taking over the alarm system from that prehistoric board was surprisingly easy. The only problem is that the alarm sounder is just a speaker. Looks like I need to set up a media player for it ๐
I'm trying to remember the name of the company my granddad worked at. He done lots of cool shit there (he was an engineer). He was part of the team that first implemented silicon diodes in the UK. He also worked on the first UK PAL TV shadowmask.
Cool story bro: I helped my grandfather and uncle build a zx80 kit from scratch when it first came out. The smell of solder always puts me back there with them. That zx80 was also my first brush with a computer, in, well 1980.
