I thought Jon Chandler’s Clock for Geeks was a great project and his idea to make a clock with two dials in a VU meter type setup was brilliant.  This is my take on that idea.

Very professional job! Im quite interested how your USB communicates with your PC application, something ive always wanted to do

I had USB comms in the "too hard" pile for a long time - it was only when Graham published his iHID: digital-diy.com/.../... program (with explanation) on the forum that I decided to take the plunge. That, and Jon's top tip: digital-diy.com/.../... about a cap on the Vusb pin made it all make sense! The Swordfish USBHID library takes care of the heavy-lifting on the PIC side.

Happy to share the source for my PC app but to be honest it's just a different front-end to Graham's iHID code - let me know if you want to see it though.

Perhaps there's scope for an article demonstrating a "hello world" type application using USB comms between a PIC and a PC?

I would be greatful to see your source code of your PC app, it looks quite a tool if im honest for your clock design.

Im definitely going to look into USB on my next project, like you I used to think USB seems "too hard"! but I actually have some 18F4550 and a 18F2550 kicking about..

I'm floored by how good this looks, from the inside-out. From the well thought out design, real subtle mix of technology with old materials, and it even has a USB port! You should consider using this as a prototype for mass-production!

One could even put 8-segement displays behind the front to display different data (not just Hours (h) and Minutes (m), but possibly bandwidth usage, email notifications, etc.

Love it!
