Controlling a linear actuator is fun and easy. They’re really strong and can be used for all kinds of things: raising your TV out of a hidden pocket; crushing your enemies; or building an RC backhoe or dump truck. I did this entire project in about 20 minutes for around $150 CAD.

Designing a new robot arm. Help!

July 16th, 2015

Here’s the post on I don’t know why I posted it there. Probably because I skipped lunch and my blood sugar is low.

I’m making a new robot arm and I don’t have enough know-how to properly attach the shoulder to the base. Can you help?

Modding an i3 to support five axis printing

July 4th, 2015

five axis printing

I’d like to mod my i3 to try five axis printing. I have a Reprap i3 and a RUMBA board that support six steppers. I see in Marlin RUMBA is set up for 3 axies and 3 extruders. The axies would be X,Y,Z,U, and V. I’m wondering what is the best approach. Here are my thoughts so far.

Marginally Clever at the Vancouver Mini Maker Faire 2015

June 8th, 2015

Best year ever at the Vancouver Mini Maker Faire! We broke all our sales records. The surprise hit was our Arduino starter kits, selling way better than anticipated. I had a surprising number of requests to see all our robots. Our two tables have only so much room!

I was delighted to hear some people skipped every booth to see us first, and I was shocked – shocked, I say! – at the number of people who had never played Tetris before.

Unlike the Bay Area Maker Faire we had the Wifi we were promised the entire weekend, media attention, Maker Happiness people checking in on us, and some really exciting opportunities to network. New to me was a menu in the Maker check-in package and a slip to write down an order. That way a Maker Happiness volunteer could go get lunch and the Maker wouldn’t have to abandon their table. So thoughtful!

Next up I have to prepare to attend Geek Picnic in Moscow. It’s like the Russian Maker Faire. Follow us on Instagram to see pics while I’m over there.
