After seeing the working mini cannon on YouTube myself (preauxphoto) and Gregabyte started talking about how much fun it would be to have one (for purely scientific research of course.) I began to think that maybe it wasn’t a pipe dream and it might be possible. I began to look around and found us some 1″ brass round stock.  From there it was just some time at the lathe and mill. Within an hour,  we had a working prototype. Though it is about 4 times the size of the one in the video, it’s still fun. It measures 1.5″ in total length, 1″at its widest and 3/4″ at it’s smallest. It is designed to take 1/4″ steel ball bearings and a 2mm fuse. Though the first couple of shots were less than spectacular, we will see if we can get near the awesomeness of the one in the video. Updated with more pictures after the break.

Preaux’s tattoo

One of our members took the undying oath of geek love recently, stating their passion for the hackerspace movement and the sense of family that can only come from people of similar interests. Last Friday after the 2600 meeting, he went to the local tattoo parlor, The Blue Rose,where he had an appointment with Caroline. This beautiful and talented artist was gentle with this burly man knowing that he had a heart of gold inside and he was looking for a way to show his love for his fellow geeks. Within 45 minutes the deed was done and PreauxPhoto (Scott) had been marked for life with his love for all things geek.

This Mind Flex project is a re-imagining of a similar design LINK  Where a Mind Flex EEG device has been modified to output and log brain functions via a serial connection to a laptop. The laptop is running on battery power alone as you should have no current plugged in while connected to an EEG.

This altered design has similar concepts though this version is a little different as there is no tether with an Arduino,  rather information is being transferred via a serial to Bluetooth adapter.  The Arduino was removed to reduce some of the bulk and increase battery life on the laptop. Serial to BT

The adapter is powered by the Mindflex power supply and also the serial line. when the Mindflex is turned on the Bluetooth is turned on simultaneously outputting information from the subject’s brain to the computer for logging.

Also a self designed software library was created for this project and runs in the background for logging data. lib
