AvE shows us that you don’t always need a complex expensive setup to drive industrial equipment. A simple Arduino setup is shown here to perform some simple stepper manipulation. The Arduino is connected directly to the Stepper driver which handles all of the complex microstepping etc. All the Arduino needs to do is enable it, chose a direction and pulse some steps at it. The result is a nice
DIY has used OpenHab is used to build a home automation control system using a Raspberry Pi. They are controlling an RGB strip. They are using some Adafruit modules to interface the Raspberry Pi to the light strip. “openHAB is a software for integrating different home automation systems and technologies into one single solution that allows over-arching automation rules and that offers uniform user interfaces. This
Kevin Hou built a Wood Turned Bowl with Inlaid Letters as one of his final high school projects.  He used sketchup for design the bowl and common power tools to bring it to life. His school has a very well equipped shop, most of the build was created with conventional woodworking tools except for the letters which was cut out on a CNC machine. The build took 60 hours and was
Tinkernut took a vintage camera and smoshed it together with some mini technology to re purpose it. A Raspberry Pi, camera module, WIFI module and screen is used as the wireless camera. The completed system sends each captured picture to the cloud. The code is very basic but turns this device into a robust IOT device that is fully functional.
If you are looking for a project build that can probably be put together with some items out of your junk box and about $10 in parts. The main drive for the system are the motor units from 2 old DVD drives. An Arduino controls the system. “components used 1. 2x old PC DVD Writer 2. Arduino nano 3. Small servo motor 4. L293D 5. Zero PCB”
1000 watts of light doesn’t sound like much. But 1000 watts of LED light mounted to the bottom of a drone flying overhead looks amazing. The video captured at the end of the video is stunning and the smoke scenes are mesmerizing.
A power supply is the heart of any good electronics lab. Hansaka Perera built his instead of purchasing one. It sure has a ton of bells and whistles. I don’t think I have seen a supply that shows what it is pulling from the wall, the LCD display in the center of his shows the total draw from the wall plug. The case of the supply is very nice and
