We’re joined in the studio once again by John Park from his DIY projects TV show on public station’s across the country called ‘Make.’ He’s come back with even more stuff you can build yourself and he’s going to do some fancy demonstrations for us.

Take for example, a Twitter hack that makes your device tell the world what it’s doing, a unique instrument called the Thingamakit, and something called the Twitchie. This John Park appearance is apparently brought to you by the letter T!
