Moogle shares results of his exploratory hacking with the ASICMiner Block Erupter, using an external clock signal and variable voltage –
I used a 10K ohm pot to adjust the core voltage with a volt meter on the pin I soldered to the main asic core voltage line. You should be very careful if you use my method and always have a volt meter on the asic core voltage line. I mostly did changes with the Block Erupter connected to my bench power supply with the current limited to prevent any mishaps.
Sadly, one ASIC was lost during the procedure, may its sacrifice not be in vain – learn more over at WTFMoogle
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
