1. Spectrometry Kit – I

    I got my foldable spectrometry attachment from the PublicLaboratory.org Kickstarter. Here’s the first result from testing with a typical CFL. I think it needs a little adjustment, but it’s working. :)

  3. Awesome Model Rocket Launcher

    In Progress…

    I never got to build my own model rockets as a kid. It’s surprising really, since I spent a lot of time launching far less flight-worthy objects through the air with ridiculous feats of garage chemistry. Remember this was before the days of YouTube (*sigh*, amateurs). So when I ordered a pair of model rockets for my nephews I was undoubtedly more excited than they were.

  4. Cheap Arduino Bluetooth

    Arduino BluetoothMost premade bluetooth modules for Arduino, particularly in proper shield form, can be pretty expensive for just kicking around on the workbench. This turned out to be a pretty easy alternative that’s also relatively inexpensive.

  5. Arduino Patio Light

    Arduino powered LED patio light

    I decided I need a patio light for evenings spent hanging out on the balcony. A proper lantern would have been a bit much, and a flashlight wasn’t quite what I was looking for. So with an old mason jar, four LED’s and resistors, and a spare atmega chip sitting on the bench, I decide to just slap one together.

  6. Last Minute Cheap Solar Filter

    Tonight is the last Venus transit until 2117 and I didn’t really want to spend a ton of money on an off-axis or full aperture solar filter for my 130mm reflector. Looking around a bit I found that a common kind of black polymer sheet is often used to make less expensive filters instead of the more common (and expensive) Baader Planetarium AstroSolar Film.

  7. Create and Edit Ubuntu Unity Launcher Items

    I’d love for someone to point me in the direction of a (working) app to better manage the Ubuntu Unity launcher items. I needed to prefix a “gksudo” on a launcher item for regular use (don’t ask), and couldn’t figure out how you’re supposed to do this. In the meantime I’ve worked this out…

  8. Arduino GPS – On the Cheap

    I had an old USB GPS puck sitting around and wondered if I could make it play nice with the Arduino. Of course, there are easier modules (including this one in serial) that can be found elsewhere for a few dollars more. But assuming you have this one, it can be done.
