I built a machine to walk my FitBit for me. I call it the FitBit Cheat-O-Matic! Why? Our office is having a FitBit competition this month (November 2013). In preparing for the competition I overworked my Achilles tendon and could not participate. So, I adopted the mantra:

If you can’t join ’em, beat ’em.

The FitBit Cheat-O-Matic is a machine that shakes my FitBit for me 24 hours a day, 7 days a week and does it faster than my normal walking pace. I suppose it’s actually faster than most people can run, for that matter. Sure it’s cheating! Not only is it cheating, but it’s cheating at a level that’s so blatant it can’t be mistaken for anything else! It’s fully disqualified from the competition, of course. But the point is no longer to win the competition, but to be totally ridiculous and to rack up outrageous FitBit stats and make people laugh or maybe shake their heads.

How many times has this happened to you? You have a little LED project with an AVR ATmega328 microcontroller (or Arduino) at its core and you need to light up a boatload…. A dingyload of LEDs. Maybe it doesn’t happen a lot to you. It’s happened on three recent projects for me. My latest two LED projects are a timekeeping piece that illuminates 21 characters from behind and a simple LED chaser thing.

As usual I wanted to keep the component count down on these projects. I also tend to prefer not to use a ton of ICs with busses between them and whatnot, if I can help it. So much darn soldering and stuff. Meh. Luckily, back in 1995, so the Wikipedia story goes, a super-smart dood named Charlie Allen at Maxim Integrated devised a super-ingenius way to control a large number of LEDs using a not-so-large number of microcontroller pins. The method is called, “Charlieplexing” and it seems a but daunting, at first, but it’s not that bad once you figger it out.

I believe I’ve mentioned it before: I work at an amazing web and software development shop called, “meltmedia.” We have a gaggle of highly talented software engineers, web developers and designers. Sometime back in 2011, meltmedia was in search of  a new tag line to kick off a for-real live marketing campaign. Marketing was something […]

At the office, we decided we were going to have a stocking decorating contest for Christmas. The rules were pretty lax, so I immediately thought of interactivity and electronics and blinky lights and whatnot. Well, that, and there was no way in you-know-what that I was going to hot glue glitter and spongy letters to a stocking […]

I was contacted by Element 14 (Newark.com) recently about doing some product test drives using some of the products from their line card. I took two to three seconds to think about it. I know, tough one… I have been chomping at the bit to use ZigBee wireless technology in a project. Digi International makes […]

Well, we’ve moved into a new and larger space at the office and we sit at these massive wood and steel desks as teams. Our team decided we needed more “flare” at our desk, so, of course, a big-ass warp core was the first thing that popped into our heads. How hard could that be? […]

EDITOR’S NOTE: I’ve attached PDF files of the pentagon PCB and the motherboard PCB. If I had time to label them and make them pretty, I would, but this was never designed for mass production or consumption. Use at your own risk and frustration. For those with a short attention span, I give you a photo […]

A coworker walked up to my desk and handed me this USB-controlled Nerf-esque dart launcher thing from Think Geek because it wasn’t working. If it was dead, I thought I’d at least get a number of little motors and gears and whatnot. I took it home, removed all the screws and completely dismantled it to […]

For those of you with short attention spans, like me, here is a quick and lame video I threw together in iMovie: I am building this for the new awesome bed I will be building this winter for our bedroom. There will be two of these lamps, one for me and one for my wife […]

I’m building a bright LED reading light that will be powered by a “9V” wall wart power supply and will use a flexible stem to position the light to not disturb my wife while I read and she sleeps.
