Our hardware division FiberCoptics is preparing to begin selling our CPULED device which has been used internally for many years. It is a peripheral that attaches to the parallel port and displays CPU load on an LED array. It comes with a highly configurable software controller.
We have not yet set a price point for it and are determining how much interest there is for this device. For more information please contact us.
Eleven years later, I finally got around to making a USB version (and then another device that shows even more system information on an LED screen). Yay for Arduino. đź‘Ť
