    We Are Awesome!!! 

    October 4 Hacknight
    We take stuff apart, we build things, make stuff work, and put cool stickers on our laptops.
    A CD duplicator was disassembled. Brad’s CNC mill is coming along, every week closer to cutting, and his 3D printer got another job. (a small test print)

    At at the Jun 23 Columbia Gadget Works meeting we did some experiments with non Newtonian fluids. Ryan coated a speaker he had laying around in red plasti-dip to water proof it in hopes of using it again later. Unfortunately the speaker did not survive the tests.

    Hack Night 

    We have officially decided to go to the state fair!!! You can see us at the Show Me Robots tent. We saw many new faces tonight. The speaker from the last hack night was ripped apart discovering why it died. Scott showed off his cigar box amp.

    Take apart night 

    We saw many new faces at this hack night. A printer was brought and decided to not work. A new idea was devised to shred old acrylic 3D printed plastic. Work was done on this idea, but there is still more to do. Many-a-things were taken apart.

    My external harddrive has developed the click of death. I decided this was a perfect opportunity to use the contact mic I assembled with help from CMKT4. Click of death.mp3 (346.5 KB)

      Mine did the same thing a while back, had to replace it. The contact mic worked pretty well to record the sound though.

    I uploaded the schlieren images/video I took this weekend. I improved the illumination and focusing, so that a larger volume was imaged, to good effect I think. I am thinking of putting together an instructable, and a thingiverse thing with my 3D printed optical mounts in the near future.

      Hello Scott,
      I saw a picture of you showing your Software Defined Radio (SDR). It looks like one of the USRP models from Ettus Research (ettus.com). Is that right? I have been thinking of using a digilent FPBA board plus a KNJN flashy ADC to make an inexpensive SDR.

        It was an Ettus USRP. I also have a FunCube Dongle. Some of the other guys are working with the TV tuner that has gotten some press on Hackaday lately (don’t remember the name).

    Thursday may 3rd, CMKT 4 

    This next Thursday we will have the privilege to host CMKT at Brad’s shop. They will be bringing kits and to build for $15 so bring some money. It should be a lot of fun.
    Here is their little blurb:

    Build an EconoMIC Bottle-Cap Contact Mic with CMKT 4 $15

    Circuit-bending rock trio CMKT 4 will help students build a sturdy, working piezoelectric pickup using components and recycled materials. The band will help you learn to solder and ensure your success in building the kit. The comic book instructions will help guide you through their special process of soldering, drilling, gluing, zipping, and dipping – Voila! You are the proud owner and maker of your very own EconoMIC Bottle-Cap Contact Microphone (from Creme DeMentia). This simple transducer will create an audio signal from physical vibrations – like an electric stethoscope! Stick around for a performance from the band while the tool-handle dip dries!

    See you there!

    A lock picking marathon!
    every one was picking locks, for many this was their first time. I think every one had a good time and much was learned.
