Feiyu Gimbal Serial Hack – scanlime:021

Join this reverse-engineering journey where I wind through software and hardware in a Feiyu Tech Mini3D gimbal, in order to give it serial controls more suitable for my Tuco Flyer robot project. I start out by taking apart the wire protocol used by the settings app, then after accidentally breaking the gimbal we have to dig deeper into the firmware to fix it again.

This edit has been compiled from live streams between April 8 and May 12, 2017.

scanlime:020 – TSG95 Color Bar Generator Teardown

Little teardown and exploration of an old bit of NTSC / PAL television test equipment, the Tektronix TSG 95. We’ll poke around with the oscilloscope and analog TV, and we even stumble on some helpful documentation.

scanlime:019 / Gimbal SDI Camera Mod

This is a mechanical and electrical modification to the Feiyu Mini3D 3-axis brushless gimbal, so it can hold a Crazyfire HZ-100P SDI camera and LIDAR-Lite distance sensor. Now I can use this small and inexpensive gimbal for the new live streaming cat robot!

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.
