Got my new chemical fueled projectile accelerator in the other day. Complete with report attenuation device for user hearing protection.
Link2
linked because its a big pic.

100% legal, including 5 month BATFE wait period for background check. So no one flip out about the suppressor ;) I figure there could be enough video gamers here that there might be some appreciation for it :) I'll be getting around to more on topic stuff for this board soon enough though, just got a new ICD3 in the mail and In old scanner to make into a UV exposure box for etching PCBs

Full science ahead!

Not really, more for utility and preparative work such as distilling/recovering solvents, or distilling the product from a reaction....

Last Wednesday I received a nice packet from Conundrum.

A nice 100w led, mounted it to a proper heath-sink with a nice delta-fan and powered it up with some very bright results wink I plan on making a focusable torch with it running on a 2s2p lipo pack with 3600mAh cells.

Ow for those that think tdu was joking with burning a hole trough a cd cover, this is what it did in 20 seconds @ 2cm away from the led.

My school just got a premature christmas present from Statoil, and amongst a truckload of expensive pressure transmitters and regulators was this: A three phase variac, input 230V output 0-250V, rated at 11,5kVA. amazed

My blurry friend on the left is exited too, but that is his thumb. In case you were wondering.
