improvisational forward/reverse engineering, and cat
Finally some locomotion for the flying camera system, it’s a 3D printed 1-dimensional robot that knows how to hang out on a network and pull rope.

To understand a program, it helps to see it first. This episode is all glitching and USB, turning a chip’s environment against it to slurp out hidden code.

The tool I use here is the ChipWhisperer. I’m not being paid or anything, I’m just a fellow hardware engineer who likes the tool and extended it a bit. Learn more about Colin’s project at: https://newae.com/tools/chipwhisperer/

Finally, another Boldport video! This time a short music video based on the Engineer Superhero kit, assembled in original form and in a variant that includes a coin cell to power the LED and a piezo button to charge the 2N7000 MOSFET gate and make the LED glow for a while.
The sound track was something I made specifically for this vid; I put it on soundcloud too: https://soundcloud.com/scanlime/metal-piranha
This time we’re looking at the protocol that powers Wacom’s wireless pens, and taking a deep look into the logic circuits (74xx!) that make them run.

This time we’re hurtling through the layers of technology that make a graphics tablet (pen tablet) work, from operating systems politics to electromagnetic induction. I’ll be looking closely at two tablets, the Wacom Intuos Pro and Huion H610PRO, and going into a full teardown on the Huion.
This video takes a close look at those little chirping sonar cylinders that might have helped your robot avoid bumping into furniture. They’re sort of like a microphone or a speaker, but looking closer they seem more like a tiny tuning fork with a hat.
I had another video planned, but today the yak stack needed tending after my trusty 10 MHz signal generator started buzzing horribly. Today’s video will be a teardown, repair, and mini-review of the 2007 vintage Protek B8010FD.
Let’s use the glow discharge in a flicker flame bulb to make some weird neon art. This video is a photographic tour and rebuild of a simple glowthing made from a novelty light bulb and an old CCFL backlight inverter. It might have left me with more questions than answers after the laser pointers came out.
I jumped at the opportunity to get hardware in the mail from another like-minded art hacker. In this video I’ll unbox the kit, assemble it delicately, and finally I’ll have to make some squiggles and beeps with it.

Continuing the adventures from Part 1, this video wanders along several tangential paths, trying to get some data out of this device worthy of reversing. This time we spend a bit more time in IDA looking for Z80 code, tinker with SCSI trying to break things, and we even do some necromancy in trying to get grumpydisk working.
