Light Painting with Temperature

DSC_8244

Inspired by the Public Laboratory and having just finished a round of college applications, I decided to experiment with thermal imaging on the cheap. Thermal cameras are expensive. Even at low resolutions, it is not uncommon for a decent thermal camera to cost over $10,000. However, for only $20, you can buy an infrared thermometer that reads […]

Three-Wheeled Go Kart

I recently had the pleasure of working in the shop of a good friend of my grandparents named Mark. Mark’s shop is just awesome – milling machines, giant metal lathes, a TIG welder – he’s spent years collecting some of the coolest equipment I’ve ever seen. Mark was kind enough to let me use his shop […]

Honey Bee Tracking Box

My school is kind of strange. We don’t have a cafeteria, but we do have a four week course on “The Simpsons.” We don’t have a jungle-gym on the elementary playground, but we do have a half-buried firetruck. We don’t have a football team, but we do have a bee-keeping club. It’s pretty awesome. This […]

Restore & Modify an Original DMG Gameboy

leadin

Released in 1989, the DMG (Dot Matrix Gameboy) was the first Gameboy Nintendo ever released.  It’s a lot of fun to mess with, so here’s a quick guide of my experiences taking apart, restoring, and modifying the DMG with an awesome new backlight. The Gameboy I had was in fairly good condition, with the exception […]

Vex Sack Attack Scoring App

IMG_0135

After releasing my last Vex Robotics scoring app the day before last year’s world tournament, this year I decided it might be a good idea to start just a tad earlier. This year’s competition, called Sack Attack (I know, I know…) operates on the premise that each alliance’s robots score as many ‘sacks’ as possible […]

Air Ionizer

diodes

I’ve been really fascinated lately by magnetic and electric fields and how they interact (mostly influenced by my interest in magnetohydrodynamics). One relatively simple but fun project is an air ionizer. The one I’ve built converts mains voltages (~120VAC @ 60Hz in the US) to something on the order of a few kilovolts at a […]

Robot Arm

For this year’s science olympiad competition I built a really cool robotic arm with my friend Ben Katz. I’ve already posted about the controller for this arm, but the whole thing is pretty awesome. The arm has 6 points of dexterity- base rotation, the lower arm, the mid arm, the upper arm, wrist rotation, and the […]

Lots of crazy-cool updates below! I’ve been working with a friend of mine, Nat Emerson, on a midi organ project.  Nat wanted to keep some of the retro-style of organs from the 60s and 70s, but instead of controlling actual analog components, it would output a midi signal to control software running on a laptop. […]

Robot Arm Controller

  Science olympiad is coming up!  This year one of my events is called “Robot Arm”.  The rules say you must construct an arm that can drop various objects (D batteries, nails, other things the judges had sitting on their desks when writing the problem) into specific bins. To control the full sized arm, I […]

Vex Gateway Scoring App

app

You might be familiar with the Vex Robotics competition.  This year I thought it would be great to create an iPad app to aid in the somewhat complicated scoring process. This app was a lot of fun to make!  Currently, the flow is something like this: When a piece is set down, we get the […]
