From another group: "Some guy on the internet has but together cheap Arduinos for just $9 + shi= p - he had a kickstart target of $12,000 but that has been exceeded (and how) so he has thrown in a lot of extras - this is now incredible value for $9 (the Arduino alone is a $25 item here in the UK) http://www.indiegogo.com/projects/9-arduino-compatible-starter-kit-anyone-c= an-learn-electronics=20 " This one is a little shakey. It seems to me it could be vaporware and my=20 PayPal was executed immediately. I have found the Arduino to be a "Swiss Army Knife" kind of device in my=20 shop and more than one is useful. My rule of thumb has been not to make a PC board or use a Proto Board if=20 I can get a commercial board for $10. I placed an order for 5 ($50) and if I get taken, it won't be the first=20 time...
