Weekend Project: Simple rocket launcher

For years I have wanted to make a simple device to launch a model rocket. This Saturday, my son Tim and I built it at the Makerspace. The launcher consists of a project box with some external connectors for the wires that go to the rocket, an arming switch, an LED to signal that the circuit is good, and a launch button. It took about four hours to make including several mistakes and backtracks.

We tested the circuit and it works as planned. The real test will be tomorrow when we attempt to launch some rockets at the park.

Brown Dog Gadgets on Kickstarter

Kickstarter

Joshua is a recent addition to Milwaukee Makerspace, and as we mentioned before, he runs a kit company called BrownDogGadgets. Well, the latest on Joshua is a Kickstarter campaign he’s running… and yeah, did we mention it’s over $71,000 now!?

He originally had a goal of $5,000 but the backers showed up in force to support his Folding USB Solar Cell project, and even though it’s been cloudy and raining all week here in Milwaukee, it’s all sunshine and smiles at the success of the campaign so far.

Check it out on Kickstarter if you’re into solar power, got an iPhone you need charged, or just like brown dogs. :)

Raspberry Pi Challenge Update

Just a quick update on the “Milwaukee Makerspace Traveling Mascot” project as I caught Eric doing a bit of Raspberry Pi + GPS hacking last night.

Raspberry PI + GPS

I’m excited to see how this project progresses. I’ve not had a chance to get hands-on with the Adafruit Ultimate GPS Breakout yet, but there’s a great tutorial on using it with a Raspberry Pi and one that covers Arduino usage as well.

Remote-Controlled LED Room Lighting

This gallery contains 4 photos.

My apartment has sub-par to poor lighting.  Combine that with our lease’s “no painting walls” policy and you’ve got a one-way ticket to Drab-ville.  Many moons ago I planned to replace the over-cabinet lighting in our kitchen with RGB LEDs controlled by Arduino, but I never found the motivation to actually do it.  Then one […]

The Raspberry Pi Challenge!

Raspberry Pi Challenge

Thanks to our friends at Adafruit Industries, we’ve got an awesome Raspberry Pi Starter Pack (and a few other goodies) and we decided that rather than fight over who gets to play with it, we’d issue a challenge to our members: Tell us what you’d build with the kit.

The results are in, and we’ve got a bunch of entries to look at before we decided who will be chosen take on the challenge. Hopefully in the next week or so we can reveal what the winning entry is.

But don’t worry, we’re going to share a bunch of the ideas right here on the blog. We may not get to build them all, but we’ll do our best to highlight some of the ideas that our members have come up with.

(If you’re looking to get into using the Raspberry Pi in your projects, you’d do well to check out the Adafruit Learning System’s category on the topic.)
