3D printed filer

Posted on December 9, 2021 by robertwilkie

OK the author build a tool to file away at something. Hum…I wonder if a belt sander would have been a better build here. Still nice build. The author seems to build alot of 3D printed tools. https://www.homemadetools.net/forum/3d-printed-die-filer-87342?homelistings#post188785

Using a fingerprint sensor and arduino for a BIO authentication

Posted on December 8, 2021 by robertwilkie

Basically you authenticate your stored fingerprint to the arduino, that then issues the unlock (password in this case as an HID interface) to the computer. Interesting build, would be easy to hack. https://www.instructables.com/PC-Fingerprint-Login-Works-on-Any-Computer-xiao-Ar/

Posted on December 7, 2021 by robertwilkie

Posted on December 3, 2021 by robertwilkie

OK this is a clever build, using an old android phone, arduino, and a motor, the author make a 3D scanner. I would simplify this a bit more by not 3D printing the holder for the phone, and just use … Continue reading →

Nice video on Component Testers

Posted on December 1, 2021 by robertwilkie

I actually don’t have one myself. But its on the list. Most of the time I am either looking up the part number, or finding my resistor chart. But for $10, this is nice. All based on an arduino too.

Posted on December 1, 2021 by robertwilkie

Reminds me of doing this on TV remotes, the author basically uses the joystick to go thru the alphabet and click the letter to select, then click end and the word gets “scrolled” by. https://www.instructables.com/BBC-MicroBit-Joystick-Keyboard/
