USB stack for Arduino that allows drag and drop

Basically it lets you treat the arduino like a USB drive to put files onto it. I needed to do this with one of my own projects, so having a simple TinyUSB library to do this is nice.

A double headed CNC plotter

I got a kick out of this, the author build another CNC out of PVC, this time it can “draw on both sides to make duplicate pictures at the same time. I like how the “z” axis is CDROM drive … Continue reading

Another nice CDROM to CNC build

What I like about this build is the only bits you use from the CDROM is the rails and motors, the rest is 3D printed parts. My 2 cents, I would use the motor and slide 3D printed parts, but … Continue reading

Impressive LED display build

If you need to make something like a score board and a clock. I like the build but I started thinking, instead of 3D printing the frame, it maybe quicker to use simple boxes and cut out the display part … Continue reading

A cheaper eggbot build

OK this is one of the cheaper and not looking cheezy builds I have seen for an eggbot. The sides are cut from wood (pattern available). Base is maker bar. Overall a simple build. And…instead of an arduino, its using … Continue reading

Make a simple mouse jiggler

OK so I have a need to keep a computer from going into sleep mode, unfortunately the system was configured in a way by the IT dept so we can’t turn off sleep mode. So…using a digispark (arduino clone that … Continue reading

Using a fingerprint sensor and arduino for a BIO authentication

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/

A simple security cam robot

OK so using an ESP-32, the author can remotely control the robot (well has to be on its wifi) to roam around and see whats going on.
