I have never seen this demonstration before. Water running through two small open cans into a larger metal collection container wired together to create 10,000 to 15,000 volts. Is it an accumulation of static electricity? If someone knows what is happening I would love to hear about it! Via: Zedomax
The Dish Maker looks like an interesting product but I think the “recycling†process might be understated. There are issues he needs to address. I hope he made a platter or mixing bowl function. What about strange shaped dishes or pitchers? Will this machine make measuring cups as well? I know my utensils take up every inch my plates cups and bowls do. I am assuming that the dirty dishes will
Check out the latest keyboard project over at uC Hobby. If you want a free LCD display from uC Hobby, read this. “Here you see the controller board sitting in the new box with the wires soldered on. I did do some modifications to the switch box PCB. The red jumper wire provides an isolated ground for the LEDs. The two wires, orange and white in upper left get power
Have a look at this cool High Altitude Balloon Experiment that is unfolding. Bre Pettis (many know him from Make) is one of the people involved with this project. There is lots of construction details and specs. up and tons of construction pictures to look at. The launch date is March 4th so stay tuned… “This project is launching a (relatively) high altitude balloon carrying a number of digital cameras
Sapa responded to this article with an example of his creative PCB exposure system made from an old computer scanner. “I have build UV LED lightbox using old flatbed scanner and 40 Kingbright L-7113UVC LEDs. These LEDs have narrow ray (+-10 degrees), it helps to get sharp shadow on photoresist even if photomask is not cling to the PCB very tight. LEDs mounted on carriage moved by stepper motor (scanner’s
Someone needs to make a diy version of this. I would totally drive my car using brain power. Or at least send it to this guy to add to his car. “A monkey has a microchip in its brain which allows it to move a robotic arm as if it were its real arm.”
This power supply meter allows you to keep you eye on your load and voltage with a nice digital display without hooking up a bunch of separate meters. How many times have you hooked up a current meter to a project being constructed to see how much juice it’s pulling? Well with this display that second meter can be put to better use! Schematics and code is provided. “This multimeter
