These Tiny Drawbots Put Unique Doodles on Coasters — Make: DIY Projects and Ideas for Makers

In order to produce something interesting to bring to a monthly hardware meetup, Barton Dring created custom laser coaster engraver/cutters. Read more on MAKE The post These Tiny Drawbots Put Unique Doodles on Coasters appeared first on Make: DIY Projects and Ideas for Makers.

This design is the 3rd evolution of marking up a coaster.  Watch the video of the machine in action, it’s mesmerizing.

GMH 053 Project Build a better Arduino blink sketch, Hello World, Ham style

Hello from KD8VON. The standard Arduino blink sketch used to confirm your Arduino board is working is just too boring. Being an Amateur Radio Geek I wrote this sketch to blink hello world out in Morse code.

Who knows Morse code? Some amateur radio operator, some pilots and a few Geeks like me.

This video and sketch are dedicated to Harvey Ernst who introduced me to Ham radio and electronics back when I was 13. Thank you.

GMH 052 Project Build Keep your Corp PC awake aka ImF15

Keep that corporate PC from going to sleep after inactivity. This video is a beginners introduction to the Arduino IDE,. ATTiny85, and the special sketch named (ImF15) that presses the F15 once a minute to keep your PC awake.

Make the ATtiny look like a standard type keyboard by using the proper VID/PID combination.

Depending on your skill level you can skip to
5:30 – Add Attiny to Arduino IDE
11:50 – The ImF15 sketch code.

Beware of the clones. Some fake ATTiny’s will cause issues on some systems.

GMH 051 Project Build DIY Overhead Camera Rig – “Natalya”

Project build of a DIY overhead camera rig to replace the first one I made from PVC pipe. Video of the first overhead rig called “Charlotte” is at https://www.youtube.com/watch?v=YVlhEDTJ7Zk&t=512s. The new one is made from cast iron pipe and mounted directly to the table. The stronger sturdier one is called “Natalya”

Video also has some of the lessons learned from the use of PVC pipe and admitting failure so those lessons can be appreciated.

GMH-013 Project Build Electronics Instrument Case

GMH-013 Project Build electronic test instruments case. Please excuse the audio I am testing out a Blue Yeti and I had the gain up too much, better than the first time when I didn’t have the damn thing plugged in. One of the design elements of my lab is that it needs to be portable. This carry case, which is an unused camera case, includes my test instruments which right now are kinda basic.This was a lazy Sunday build using exercise mats as the foam for the custom cutouts.

TIP: Use a really sharp knife and change the blades, the exercise foam really dulls them quickly.

Shout out to Julian Lett for inspiration and humor.
