Does anyone know where to buy 10 or 20 segment bargraphs that use blue LEDs? I have done a cursory search on Google and eBay and the only people selling such a thing are Chinese factories that are only interested if you are a Big Retailer and want to buy pieces in blocks of 10,000. I know…rectangular blue LED’s are falling from the sky on eBay, I could just build a bargraph using discrete LED’s and some DIP-sized boards from BatchPCB… but it would be nice to have an integrated solution in a standard plastic bargraph package.
You should send a message to www.curiousinventor.com. I know they use these blue led bar graphs in their stribes.
