The Makertum MK1 is a mains voltage heated bed for 3D printers with dual voltage support (230/110 V~), 500 W of heat output, 2 minutes heatup time (110 °C), power indicator LED and onboard thermal fuse. The beta test was overly successful, and preproduction boards are available now in the Makertum Shop and on Tindie. IMHO, it’s pretty much nuts to convert down mains voltage in a power supply to 12/24V just to drive a large heating element, exc...

Being a budding beginner hobbyist in electronics with about a year blindly stumbling about with Arduino and ESP8266, just completed my DYI "Third hand" i figured i am committed enough to have a stab at the mandatory ATX to Bench Power Supply conversion so my plan is to use an old ATX case from a PC and an old ATX power supply both of i which i have plenty of on hand, and add an additional 36V/5A CC PSU and convert these to a current limiting Ben...

The Venus robot Monster is a home spun robot(The heart of any good Sci-Fi story) I am building from bits and pieces of acrylic,3D printing and some Styrofoam that walks upright, has flashy lights, speaks, moving arms and presents data about it mission on a small TFT screen.
