Another day, another couple of cool, wacky vids from Fatman and Circuit Girl. In the first vid, Jerri has George laughing his butt off over her ridiculous flipdown clock wrist watch. Tres chic, it ain’t!

In the second video, Jeri explains EDM, electrical discharge machining, a technique that came up recently on Make: Talk. She hacks up an electric doorbell and uses it solenoid to power a little EDM armature that cuts through a razor blade.

The Fat Man and Circuit Girl

  1. Does anyone else find these ‘Fatman and Circuit Girl’ videos extremely annoying? They’re really poorly made, seemingly intentional which adds to the annoyingness. The ‘Fat Man’ is pointless and distracting and is slightly creepy, it even slightly perverted that an old looking man is on the webcam to some young girl. His constant headshaking for no apparent reason in another video also pissed me off a lot.

    If anyone happens to talk to this girl, tell her to ditch the old fat man and do the videos on her own, spend a bit more time editing and getting it right and don’t use micrometers to hold things.

    1. That’s exactly what i was going to say! Why have a split screen with one half some good hackery and the other a guy just laughing all the time and going “AWESOME!”?

    2. Junk Micrometers are a dime a gross, good micrometers a dime a dozen. Back when the economy was good, just out of spec micrometers might have had some value.

  2. I suspect she’s a prop. I have difficulty believing she’s the one setting the stuff up, since she doesn’t seem to have a good grasp of what she’s demonstrating.

    Perhaps she could run for office.

    1. She actually is an Electrical Engineer who designed the “Commodore 64 emulator within a joystick, called Commodore 30-in-1 Direct to TV.” http://en.wikipedia.org/wiki/Jeri_Ellsworth Just because she’s cute doesn’t mean she’s not smart. I think the Fatman is more of a prop than she is because he’s basically a soundboard to throw her ideas against. Maybe she’s just shy. There’s no crime against that.

  3. the fat man is my personal hero! he composed a lot of game musics and made gm tibres for opl2-3 soundcards. a genius.
    so don’t f**k with the fatman.
    his full name is george alistair sanger btw.

  4. Oh no, using a device for something other than its intended. You can’t possibly be allowed to do that!

    1. It’s not as though it would damage it, it’s just that it’s not intended for that and so looks stupid imo. There are also far easier ways to hold the blade as well, or make a stand to hold the device, than it is to attach the micrometer.

  5. For the people who cued into the use of a micrometer as a c-clamp. There is nothing sacred about a micrometer. The only thing sacred about a micrometer is where it is in calibration classification.

    In our shop there were three calibration classes: 1. Precision Grade (god), 2. Calibration Grade (cardinal), 3.General Work Grade(acolyte). As the thread in a micrometer wears, it goes out of tolerance. Once a micrometer gets to where it won’t pass General Work Grade, you take a ball-peen hammer, set it on a chunk of iron, strategically smack it and throw it in the scrap bin.

    Not sure how most people get all steam punky and assume it’s good because it’s c-clamp shaped and has a mechanical digital readout, but given her educational background, she probably knows that its accuracy is about useless and decided not to smack it with a ball-peen hammer.

  6. The demonstration of EDM was pretty good for simulating how an EDM machine works real life.

    My major experience is with using it to remove extremely hard broken taps from highly valuable, but softer objects that needed to retain their structural integrity.
