Cool mini 3D printed CNC laser engraver

Nice build, I like the re-use of the CD-ROM motors, but I am not so sure about using lasers. Drill motors I can handle but lasers make me a bit nervous. Either way the STL files for the build are … Continue reading

Interesting CNC build

Author uses 3D printer to make the ends for the frame. Nice build overall. Not sure if I would go with this over MP CNC. Bit pricey of a build with some of the parts he uses. https://www.instructables.com/id/DIY-3D-Printed-Dremel-CNC/

Make your own 3D scanner

Interesting build, it moves the object around and you use your phone’s camera to scan in the images. Uses an ATiny to controll the thing. https://www.openscan.eu/?lang=en

Interesting CNC build

could be a bit more complicated of a CNC to control, as you need to handle the table spinning. But it does save on number of motors and other parts a standard CNC would use. The write up is not … Continue reading

Make a laser chaser bot for your dogs

I have thought about doing this myself. Pretty simple build to do but looks like the laser is not too random in its movement. Thought you can change the code to be more random. https://www.instructables.com/id/Arduino-Controlled-Laser-Dog-Chaser-Toy/

Turn an ESP8266 into a WiFi Jammer

Pretty cheap jammer. The “jamming” part isn’t a radio freq. jammer but more protocol stack based. https://www.instructables.com/id/Wi-Fi-Jammer-From-an-ESP8266-WiFi-Jammer-Deauther/

Opensource hearing aid

OK after seeing how much pro hearing aids run (3 grand easy). I can see why there is an opensource project. Article indicates the board will run around $250, not including headset. But still thats 10% of the cost of … Continue reading

Nice clock build

I like the clock build, plus you can customize it. Only thing is the LED strip used is a bit pricey. https://www.instructables.com/id/MirrorClock/
