scanlime:015 / Glitchy Descriptor Firmware Grab

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.

Get the source and play along:

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:

scanlime:014 / Boldport #2 – Superhero

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:

scanlime -013 _ Wacom Teardown and Schematic-j4AKwJERxOw

scanlime:013 / Wacom Teardown and Schematic

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.

If you missed the last video, check it out for the big picture on how graphics tablets work:

scanlime -012 _ Graphics Tablet Primer for Hackers-nPab7pbOhBY

scanlime:012 / Graphics Tablet Primer for Hackers

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.

scanlime -009 _ Flame Effect-I69PWRUoeGM

scanlime:009 / Flame Effect

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.

scanlime -008 _ Boldport #1 - Pease-diZ5jb7o01A

scanlime:008 / Boldport #1 – Pease

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.

scanlime -007 _ USB Disk Recorder Part 2-0s_nALzGpeg

scanlime:007 / USB Disk Recorder Part 2

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.
