Motorola Cordless DECT Phone Teardown

Posted on August 6, 2016August 1, 2016 The Engineer

Another random teardown from the junk box time! Here’s an old Motorola DECT landline phone, no use to me as I’ve not used a landline for many years. Not much on the back, other than the battery compartment for a pair of AAA rechargables. The base unit contains the charger.

Digital Angle Gauge

Posted on June 14, 2016 The Engineer

Here’s a useful tool for the kit, a digital angle gauge/protractor. These use a silicon sensor to show the number of degrees the unit is out of level. Magnets are provided in the base, so the tool can attach to any ferrous surface. Power is provided by a single AAA

GY561 Frequency & Power Meter LiPo Conversion

Posted on August 24, 2015 The Engineer

From the factory, the GY561 meter uses alkaline AAA cells for power. As these are not rechargable, and I don’t carry any other devices that take such batteries, I figured I’d replace them with a single Lithium Polymer cell that I can charge via USB. Here’s the battery compartment, with

GY561 Frequency & Power Meter

Posted on July 18, 2015July 19, 2015 The Engineer

The latest addition to my radio shack is the GY561 frequency & power meter, which has already come in useful for measuring the output power of all my radios. It’s a small device, roughly the same size & weight as a stock UV-5R. Power is provided by 3 AAA cells.

Pringles Speaker Modifications

Posted on August 18, 2013 The Engineer

These speakers are available free from Pringles, with two packs bought. Normally running on 3x AAA cells, I have made modifications to include a high capacity Li-Ion battery & USB charging. New battery is 3x 18650 Li-Ion cells in parallel, providing ~6600mAh of capacity. These are hot glued inside the
