Hybrid Robot


[Coley] sent in this port of jetpack for the propeller uc, but when I started poking around I discovered this sweet hybrid robot platform. A four stroke Robin/Subaru 35cc motor drives a car alternator, providing virtually unlimited (in the robot world) power on demand. Hit the video after the break for a quick R/C demo and an idea of how loud the engine is. Offhand, I recognize the lovejoy coupler that was used to connect the engine to the alternator.

By the way, this bot is featured in the latest Robot magazine, so you can get details there if you hate reading forums.

PosterBot – Hack A Roomba Into Poster Printer


(I’m in a robot mood this week, ok?) [Wyatt] sent in his posterbot. Lacking the gift of girly handwriting, he grafted an inkjet printer onto his Roomba to make posters for him. There have been other bots to do this, my favorite being the graffitiwriter. Of course, [Wyatt]’s bot is less likely to get you arrested.

Want a shirt?

By the way, I’ve got a spare Hack-A-Day shirt sitting here. Send in a link picture of your Hackspace to the tips line. The best/worst will get some attention and the best one gets an official Hack-A-Day shirt.

A123 LiIon Battery Pseudo Extra


Every so often I have to slap myself in the head. I’m surprised that we haven’t covered these things by now. DeWalt’s been selling a LiIon 36 volt battery pack that’s full of the latest A123 cells. These are the same ones that were used in the Killacycle. (I think they’ve got a new batch of cells now).

A while back, [Jeff] sent in a circuit for using multiple packs, leaving the internal BMS in place. [The link is fixed now]

[Robert] sent in a scooter that’s been designed to run these same cells. The custom fabrication and machine work looks fantastic.

IR Helicopter Tracking


[Lyle] sent in some of his work with mini-copters. This rig was built to test control methods with his mini-copter UAV. I’m hoping that some attention here will get him to document a bit of his home testing for us. (He’s working on some bigger systems professionally, so I’m not sure if he will.) The test rig uses an IR camera to measure pitch, yaw and three dimensional positioning 120 times a second.

Gotthard: Intelligent Furniture


[Gloria] sent in Gottard. (English translation). This little box is designed to act as a stool – that happens to follow people around, record their conversations and play them back to other visitors as a form of interaction. A set of rotating casters provide seating support, while a pair of gutted cordless drills move things around. An Aurdino handles the robotic functions., and an iBook handles recording and playback. Ultrasonic sensors guide the movement, and a set of LEDs roughly show how full the recording drive is.

CNC Solder Paste/pick N Place


Just when I thought I’d seen most of the CNC mods out there, [Steve Ciciora] (who happens to be one of the driving forces behind the killacycle) sent in his diy solder paste dispenser *and* his diy pick and place machine. Both are extensions of his CNC taig mill. Hopefully [steve] will put up some more details of his mill mods.
