Will your low-power design run on batteries for 30 years? This design from 1981 did.

I hang out on the discussion forum for the hpmuseum.org Web site, mostly to soak up the ambiance of people who really love old HP calculators. I own an original HP 35 (the world’s first pocket scientific calculator) that I … Continue reading

Hands On Review: Texas Instruments’ Stellaris ARM Cortex-M4F LaunchPad Eval Board—$4.99!!! (sort of)

This is truly a bargain-of-the-year kind of story. A few months ago, I ordered two of the new TI Stellaris LaunchPad Eval Boards, which incorporate a TI Stellaris LM4F120H5QR microcontroller. I ordered one for me and one for my new … Continue reading

Replace an old IDE HDD with an SSD emulator to cut noise and power? The Korg D8 experiment.

I’ve got an old Korg D8 digital multitrack audio wokstation. It was state of the art for recording sound back in the mid 1990s. The whole concept of digital audio workstations was new back then. The products were just starting … Continue reading

Mars Science Laboratory rover runs on plutonium—uses somewhat less than 1.21 gigaWatts

Although both employ plutonium power sources, Doc Brown’s time-traveling DeLorean needed 1.21 gigaWatts to zip between time periods while the freshly landed Mars Science Laboratory (MSL) rover gets by with 125W to power its dual-redundant 133MHz BAE RAD 750 CPUs, … Continue reading
