Well I decided to take this week off and relax for some R&R time.

Starting tomorrow, I'll review my two circuits and make parts lists for both. Once they are completed, I'll put the order through for the Powerduino shield and its mate the Relayduino shield. The good news is that for the most part are easy to solder by hand. The bad news is the parts are a little expensive, but not by much. Maybe around 50 bucks for all the parts for both shields. So if I ended up selling these boards, I'd have to sell them for a little more to break even. I'd probably end up selling the boards individually, and include a parts list.

The Relayduino has the following specs:

-Two 30A/250VAC Relays with Quick Connect Pins
-LED Relay Power Indicators
-Quick Switching up to 66.66 Hz
-Use with the Arduino Uno

The Powerduino has the following specs:

-Power Outputs: 9/12/24 VDC (intended for Relayduino)
-Jumper header to Select which Output is Required
-Uses a MAX1771 DC-DC converter
-Shield is for use with the Arduino Uno

06/06 Edit: Teensy Relay Shields came in today, lots of technical flaws on my part. Its on my list of things to do this week. Fyi, the Teensy Eagle Library on isnt correct, the pin holes are too small. I'll be sure to let Paul know.

So not much else to tell. I'll see you next week.
