I'm Andy and I like to make stuff. Doesn't matter if it's useful or not.

Please have a look around and don't hesitate to contact me about anything you see here.

Useful

Sometimes I make stuff that's actually pretty useful. The coolidor I made from a wine fridge and an automatic cigar humidifier has been keeping my cigars in perfection condition for me for years!

Useless

I absolutely LOVE the "Ultimate Useless Machines" out on the YouTubes and whatnot. I've built several now as gifts and there's even one on my own desk in the man cave.

Fun

Most of the time, I make stuff that's just run to look at or interact with. The mood lamp I made for my wife has a custom-built dodecahedron RGB LED "bulb" inside that was art by itself.

Comfy. Fast. Lots of switches and buttons.

 

The IKEA Poäng chair is definitely up there in the ranks of comfortable office chairs. Where most people see bouncy comfort in the flexible but sturdy wood structure, I see springy suspension capability.

Now add two 3/4-horsepower electric scooter motors, a battle robot motor controller, an Arduino microcontroller and some LED lighting. Oh, right! Toss in a master control panel with over 32 actual functional buttons and switches (inluding a "Weapons" quadrant), some voltage meters and a 20-WATT sound system.

Now THAT is what I call an office chair! Walking to the conference room is lame. Getting there in two seconds is bad ass.

In fact, it's so incredible, it even has its own website and Twitter handle. Check 'em out:

A control panel worthy of an Apollo command capsule: 30+ buttons and switches and toys!

They do it on the DIY Channel all the time. You can do it, too!

 

OK, sure, the pavers are heavy and you need to get a small pile of them home from your local home improvement store, but other than that, there isn't much to making a cool back yard liquid propane gas fire pit that burns clean and hot.

See how I did it on my blog. There isn't much you CAN'T DIY these days. This propane fire pit is no exception. We've since replaced the glass beads with lava rock to radiate heat better. Either way, it looks like a million bucks!

Molds, epoxy, ribbon cable & LEDs

 

From a screenshot of the movie to a working and wearable homemade arc reactor. Read this post to find out how I did it. It also helped that my wife kinda looks like Pepper Potts, as well. Add a couple of Stark Expo badges and we're in.

"Know when it's time to go!"

 

With a microcontroller, a couple of ambient light sensors and some nifty little Mac OS X software, I was able to make it easy for people to figure out the right time to wander over to the potti.

The controller at the heart of the original iPotti #1 from 2009 defunct, sadly. Good news is that I've started working on iPotti No. 2. That's hilarious for several reasons!

Save a GPIO pin: Charlieplex an LED

 

Want to turn a handful of LEDs on and off, but you don't want to sacrifice digital I/O pins on your microcontroller? Charlieplexing is for you.

Because LEDs are truly diodes, they conduct current in only one direction. Put to of them parallel to each other but connected with opposing polarity and you can switch them with just two pins on your Arduino.
