Race Timer

This is a very brief first blog post!

I was looking back though some old videos and thought this one would make a good excuse to test out Vimeo. It’s a short clip of my prototype of Mindsets’ Rail Race Timer being tested at an event at the Duxford Imperial War Museum. Unlike most other projects where I’ve used LED displays, these aren’t multiplexed. The circuit used three TLC5927: 16 channel constant current LED drivers. The microcontroller controls the three ICs on a single SPI bus meaning each segment is constantly powered if needed. The lack of flicker means there is no strange effects when taking video.

By the way, the Mindsets High Speed Rail Racer is pretty cool. Those cars really move fast!

That’s all for now.
