Vacuum Chamber

What happens when you give makers a vacuum pump and a bin full of components to rummage around in? Watch the videos to find out.

Can you think of something interesting to put in a vacuum chamber? Post in the comments below.

OMG-FTW update

Update: Button at the bottom is fixed, now

It’s about time we get started on the power wheels racers for this year. We’re starting a fund raising campaign.

We’re aiming for $1500 and we already have $610 raised, so only $890 to go! Thanks to everyone who has chipped in so far!

$1500 sounds like a lot, but includes two battery packs, motors, motor controllers, hydraulic brakes (which are amazing, btw), and tools for the pit like battery chargers. Any money that doesn’t get used this year will be ear-marked for the next. To donate money, click the “Donate” button in this post.

We’ll update this post periodically with our progress. Check the omgftw mailing list for more info.

Acrylic Heater

The acrylic heater is nearing completion (design shameless copied from a hack-a-day post).

I still need to make a few more tweaks to it before it’s ready for use. There’s a minute amount of water leaking around the barbs, but that’s easily fixed with some clamps. I’d also like to find something better than a gladware container for the reservoir. Then there’s the brightness… I don’t think the control I’m using was made to dim something with 0.1 ohms of resistance.

Halogen bulb on low

Halogen bulb on low

Yes, the overhead lights are on in this picture. Yes, the controls are set to their lowest possible setting. Yes, it’s that bright through the smoked acrylic. I actually grabbed a welding helmet a few seconds after this shot.

I’ll post more details and possibly a tutorial video when I get this thing ready.
