Hands-on Review: $12.95 Freescale Freedom Platform for Freescale Kinetis L microcontroller based on ARM Cortex-M0+ processor
I received a new low-cost microcontroller development board only a few days after writing up the Ti Stellaris LaunchPad Eval board last month. (See “Hands On Review: Texas Instruments’ Stellaris ARM Cortex-M4F LaunchPad Eval Board—$4.99!!! (sort of)”) The new board, … Continue reading
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, Part II—Compact Flash
Earlier, I reported on my attempt to swap in a solid-state disk emulator for a small IDE hard drive in an old Korg D8 multitrack audio workstation. (See “Replace an old IDE HDD with an SSD emulator to cut noise … 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
Diagnosticians Beware: The Internet can Mess Your Mind
My wife’s car, a 2002 Saturn L300, has a problem. It’s losing coolant. I just added about three inches of bright orange GM Dexcool coolant to the overflow reservoir under the hood after having done something similar just a few … Continue reading
Charging the Chevy Volt
This is the second blog post describing my experiences with a Chevy Volt that GM loaned to me for three days in August. I’m going to spend a lot of time describing the charging of the Chevrolet Volt because that’s … 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
Driving the Chevy Volt
General Motors loaned me a 2012 Chevrolet Volt to try out for three days at the beginning of August. It’s a fun car to drive and three days—really not quite two and a half days—isn’t enough time to fully explore … Continue reading
Want a peek over the shoulders during a real low-power microcontroller debate? Must-read info for all designers of low-power, microcontroller-based systems!
Recently, I published a blog post on my EDA360 Insider blog about the ARM Cortex-M0 processor core and its expected influence on mixed-signal, low-power IC design. (See “What effect does the ARM Cortex-M0 core have on mixed-signal microcontroller design?”) As … Continue reading
