scanlime:018 / Tuco the Cat’s Robot

Meet my cat, Tuco. He’s a polydactyl American Curl kitty who loves fetching nylon 1/4-20 bolts. This is a video introduction to the new project I’m building and streaming, a camera robot for interacting with Tuco online.

scanlime:017 / Boldport #3, Cordwood Puzzle

Assembling the Cordwood Puzzle, an electronics kit from the Boldport Club subscription service. It’s a close look at a relaxing build with a vintage look and delightfully unique design. Check out Saar’s work: https://www.boldport.com/

This video was filmed in front of a live Internet audience. Stream archives:

scanlime:016 / Shiny Blue Vacuum Fluorescent Pole Thing

I’ve been streaming lots of live forward and reverse engineering lately, and I’m about to start editing some of the recent work into a multi-part series of videos! But this little self-contained project had been sitting partially-edited in my queue so long, I had to give it the finish it needed.

Here we have a retrospective look at an old Vacuum Fluorescent Display project, and a re-make into something new using 3D printing and magnets.

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.

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/

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: https://soundcloud.com/scanlime/metal-piranha

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.

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

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.
