Data run with a copper coil

Well I’ve spent the last few days writing about 3000 lines of code for a temperature differential controller. With the basic configuration routines debugged, I decided to do an actual test run to see how the data worked without putting the unit in control of the pump relay just yet. I’ve got two tanks, and once the first one was nice and topped off, I switched a couple valves and heated up the backup tank.

Happy New Year

I hope everyone had a nice holiday. 2012 is off to a great start because I just got word that the first membrane keypad prototypes are ready to ship! I've been hard at work working on new software for the SolarMega1 board. I've made great progress on a temperature differential control (i.e. T-Diff) application. Getting the code to handle jack detection and configuration has been fun.

Testing 1,2,3

Sometimes the universe has ways of making you slow down, like being cloudy and rainy for an entire week with no sun. It made me realize how much of an energy junkie I am, and made me be patient getting around to testing the new boards.

First SolarMega boards are here

Here's a peak at the first prototype circuit board down below.

Cloudy days mean work

Here's a couple picture's of me working on the compound parabolic trough project. It's been cloudy and rainy for the last 5 days or so. The batteries are pretty much drained from me staying up till 2:00am working on the website, so there's plenty of incentive to do something besides work at the computer. I've spent the last 3 afternoons working on the compound parabolic collector. I've got all 9 of the parabolic sections fully built, now it's just a matter of connecting it together.

The new H-Bridge boards are here!

New H-Bridge motor driver board

The first batch of the H-Bridge motor drivers arrived today. I soldered one up and it worked fine. Yeah! I'll make the pads a little larger if I'm going to make it a kit so that it's easier to solder. I also learned that manufacturing includes TNames but not TValues in the silk screen, so I had to look at a schematic to know the values for the resistors. No biggie.

First Blog Entry

Well I'm trying out the blog feature in Drupal. The first batch of SolarMEGA1 boards shipped today from China! Hopefully UPS will have them in my hands next week. I found a Cantex 4x4x2 pvc enclosure today that could make a nice enclosure. Lots of work on the store today as well as the rest of the website as I get things a bit more organized. Still waiting another week or so to do the big anouncement.

Solar Energy, Law, and the News ....

Belmont, MA proposes zoning changes to restrict solar power:
Here's a link to the article I read:
The proposed changes would prohibit anything over 12" above most roof surfaces. That means only flat panels allowed, no trackers, no trough's, no heliostats - not good.
