Huawei E160E USB HSDPA Modem

Posted on February 3, 2016 The Engineer

Here’s an old HDSPA 3G USB modem stick that I got with a mobile phone contact many years ago. As it’s now very old tech, and I have a faster modem, not to mention that I’m no longer with Orange (Robbing <expletive>), here’s a teardown of the device! The top

Maplin 600W “Modified Sine” Power Inverter

Posted on January 17, 2016 The Engineer

I’m no fan of power inverters. In my experience they’re horrifically inefficient, have power appetites that make engine starter motors look like electric toothbrushes & reduce the life expectancy of lead-acid batteries to no more than a few days. However I have decided to do a little analysis on a

Wouxun KG-UV950P Teardown & Analysis

Posted on July 5, 2015 The Engineer

Following on from my review, here are some internal views & detail on the components used in this radio. Below is an overview of the main PCB with the top plate removed from the radio. Most visible are these MOSFETs, which are Mitsubishi RD70HVF1 VHF/UHF power devices.  Rated for a

Quantum LTO2 CL1001 Tape Drive Teardown

Posted on November 25, 2014November 26, 2014 The Engineer

I have recently begun to create an archive of all my personal data, and since LTO2 tape drives offer significant capacity (200GB/400GB) per tape, longevity is very high (up to 30 years in archive), & relatively low cost, this is the technology I’ve chosen to use for my long term

Routemaster Control Unit

Posted on October 21, 2012October 21, 2012 The Engineer

This is the control unit for a Routemaster system, that downloads traffic information for the area local to the vehicle. Here is an overview of the unit, in it’s aluminium box.           Here is the unit with the top cover removed, showing the pair of PCBs.

Vintage Optical Block

Posted on July 22, 2012July 22, 2012 The Engineer

I thought this would be of interest, as it’s from a drive circa 2001, (DVD-CD-RW). It’s the biggest & most complex optical block I’ve ever seen, with totally separate beam paths for the IR CD beam & the visible DVD beam. It also combines the use of bare laser diodes

Tool-less UK Mains Plug

Posted on October 15, 2011 The Engineer

This is a standard 13A UK main power plug – with a twist. This one requires no tools to open or connect. The top cover is slid off the top, after turning the red cam with a coin to unlock it. Manufactured by Plugco – a Google search of this

Chicom “500W” ATX PSU

Posted on January 5, 2011January 3, 2011 The Engineer

Here is a cheapo 500W rated ATX PSU that has totally borked itself, probably due to the unit NOT actually being capable of 500W. All 3 of the switching transistors were shorted, causing the ensuing carnage: Here is the AC input to the PCB. Note the vapourised element inside the
