It seems that my article on PCB Photolithography and Inkjet printers has surpassed the older articles on LED Sensors. It’s been a while since I’ve done anything with sensors. I still get quite a few e-mails about them, mostly folks asking specifically how to do something, or what the secret is. Honestly, I don’t know any more about them then what I’ve written. Most of my experiments took place on a breadboard, and were cobbled together from educated guesswork, trial and error, and a lot of reading. Perhaps I’ll revisit led sensors this summer – my PCB fabrication skills have really improved, and I can try making some ‘key pads’ which seems to be a popular request and application.
Jeff Han has started his own company selling his multi-touch technology. He never did reveal the ‘secrets’ to that impressive led matrix video which is so popular. From a business stand point, I can see protecting your IP assets, but led’s as sensors is old technology, I don’t think anyone today has a patent leg to stand on. In that light, perhaps if we all e-mail Jeff he’ll reveal his secrets to us.
Anyway, be sure to check out the ten most popular posts in the sidebar column. You can also check out the different project categories; each category has its own list of popular posts.
Thanks for reading!
