General Electric A735 Digital Camera Teardown

Posted on February 22, 2016February 22, 2016 The Engineer

This camera has now been retired after many years of heavy use. Exposure to a 3-year old has caused severe damage to the lens mechanism, which no longer functions correctly. Pretty much standard interface for a digital camera, with a nice large LCD for it’s time. With the front cover

SainSmart Frequency Meter

Posted on July 16, 2015July 16, 2015 The Engineer

Thanks to Lewis, M3HHY for lending me this one ๐Ÿ™‚ Here’s a quick look at a Sainsmart frequency counter module. These are useful little gadgets, showing the locked frequency on a small LCD display. It’s built around an ATMega328 microcontroller (ยตC), and an MB501L Prescaler IC. The circuit for this
