I've got a thing for clocks... I wonder if it's because I'm not getting any younger.
Anyway, I had a day free over the weekend and decided It was clock building time.
There's not much to this clock really. A PIC18F25K22 running some simple firmware written in AMICUS18 BASIC. There's a Dallas DS1302 RTC chip with battery backup, and a handful of other components.
I've been experimenting with different firmware to see which makes the display the most readable.
The image on the left of the clock front is showing a time of 10:20:13UPDATE 29/10/13
I've created a construction project for this clock which can be found here.
I completed work on a new Nixie Clock at the weekend; this one’s for me. I already had the tubes as I’d bought a batch of 17 off Ebay a while ago and whilst I used 6 for a friend’s clock, the rest were just sitting there begging to be used.
The design is basically the same as the original but I did take the opportunity to update PCBs in a couple of places and add some expansion capabilities.
I’ll be publishing the construction details here soon… watch this space.
I’ve got a couple of new projects, to go with the hundred of already running projects, on the stove right now. I had a brain wave the other day for a new clock (picture below) and once I’ve ironed out the kinks I’ll post full construction details for those that want to have a go.
I’ve also been chatting with my friend Max (Clive “Max” Maxfield – author of lots of computing articles and technical blogs – find him on Amazon or the Internet) about a rather exciting computing project. Who said 4-bit computing was dead.
