In all the time I’ve been been messing around with PIC microcontrollers I’ve never done a simple 7-Segment LED clock, and it’s something I’ve always wanted to do.
For the Record Time Redux project I’m currently working on I needed to design a control board for it. I started working on a PCB layout and then thought, why not make the board so it could also fit on the back of the 7-Segment LED module. So I came up with the board shown here, it fits to the back of the 0.56″ RobotDyn 4-digit clock module (see here) and turns it into a compact USB powered LED clock.
I fitted the assembled boards into a Hammond translucent red 1591 style case (size 100 x 50 x 21mm )
Schematic and PCB layout can be found on the EasyEDA website here.
The source code is fully working, just need to get some time to write up a quick projects page and I’ll make it available then.
Update: 13/06/2019 – Full project now published here
There is now a new PCB design for the original Power MOSFET RGB LED PWM Driver #106 project.
Way back in the 80’s – 1986 to be precise since I dated one of the PCBs – I made a ‘Record Time’ clock and it has lived in my parents kitchen ever since. Amazingly it’s still working 33 years later.
A few months ago I came across a post on the Hackaday website that showed a clock made using an instrument cluster for a motorbike. The clock featured in the article was based on an Arduino but I thought it would be interesting to do something similar using a PIC microcontroller. I had a look on eBay and found them being sold under the description of “Universal Motorcycle LCD Digital Speedometer Odometer Motorbike Tachometer Gauge”, or something similar and going for around £20.00
So I bought one and a few days later it arrived and the fun began…. Read all about it here
A couple of weeks back I decided to re-vist the F1 Gantry Race Start Lights project that I originally did back in 2009.
The new PCB has an extra header to make connection to relay modules easier and uses a double-sided PCB. It is functionaly the same as the original and uses the same firmware which is now free to download.
