MCM Electronics Pro Elec Battery Test - Results

Posted by John on Jul 17, 2014

Per the graph above, we learned that while the Pro Elec battery had a lower initial voltage, it lasted longer. Great. That's simple. But there's more to it.

Because batteries are used in millions of different applications, there will be instances where having a higher initial power output will be better. We'll try to qualify some of these instances below.

MCM Electronics Pro Elec Battery Test - Setup and How To

Pro Elec Battery Test

Recently, we started carrying our own line of Pro-Elec batteries, and around the office we were wondering how they really stack up against the major brands.

We had the discharge rates and expected run-times from the data-sheets, and most major brands do publish power-curves, but those didn't really give a good head to head comparison. So I grabbed an Arduino, Data-Logger Shield, and a few packs of AA size batteries from stock and got to work.

Duratool Cases a Favorite of Dual Sport Riders

Posted by Christian on May 19, 2013

We've noticed our Duratool blow-molded cases have been making a splash as a lower-cost alternative to more conventionally used cases, like those from Pelican. This is especially true with the dual sport motorcycle crowd. Often dual-sport riders require panniers and fender mount boxes to carry goods. Herb Suessenbach, of Albuquerque, New Mexico sent over some pictures of his Duratool #22-14350 installation. [More]

Bike Light Testing with TinkerKit

Posted by Christian on May 10, 2013

Today I picked up a couple of bike lights from our offering. I was off to go home and test fit them on my bikes at lunch, but upon looking out the window, we're currently experiencing monsoon-type weather. So instead we'll be spending our lunch testing these things out, namely the brightness on full-on mode. [More]

Adventures in 3D printing

Posted by John on Apr 18, 2013
While I love Maker Culture, I generally self-identify more as a kind of 1950s “Popular Mechanics” old-school hobbyist. You know the kind: lathe and mini-mill in the basement, welder in the garage, and random woodworking and electrical equipment scattered all over the house. So I have been struggling for the last few years with whether or not to invest in a 3D printer. They have always seemed pretty pricy, and I was never sure how much use I would get out of one. On the other hand, there is no question of the raw cool involved in being able to print off plastic widgets with ease, and perhaps even get involved in a little lost-PLA casting. When we started carrying the Printrbot Jr. I finally broke down. [More]

Raspberry Pi Model A

Posted by Christian on Apr 9, 2013

The Raspberry Pi Model A is the $25 computer the Raspberry Pi Foundation promised. It is the low-cost, low power little brother of the Model B boasting the same processor and high resolution HDMI output. The Model in contrast to the Model B uses only 1-2 watts of power compared to the 3-5 watts of the Model B. This makes it great for use in mobile applications where power is very limited. A perfect application for this would be a wireless media center streaming media over the network.
