ZX Spectrum +/48k - Composite Video Mod

I wasn't happy with the picture quality of the RF output from the spectrum. So I decided to do the composite video mod. Rather than just disconnecting the +5v line and routing the video signal directly to the RF output. I decided to remove the modulator circuit entirely. I also found on this website, that it is possible get a cleaner video signal by adding a 10-16v 100uF capacitor in series with the video line. Here's the pictures I took when I modded my Spectrum 48k+ to do composite. 

De-soldered the modulator from the spectrum board:

Getting into Sinclair ZX Spectrums

Recently I’ve been getting back to playing around with some ZX Spectrum hardware. I originally picked up a ZX Spectrum +2 back in September of 2010. Played a few games on it then put in to storage so I could focus on other projects. Then a few weeks back I managed to get hold of two more spectrum systems. A ZX Spectrum + and a ZX Spectrum + 128k. They were both sold as faulty and untested, but I managed to get them both working.

Home Server UPS

Recently I’ve been wanting to have some kind of power back system for my home server setup. Just a little project of mine. Though it would be cool to have in-case of an unexpected power failure while doing data critical stuff. Also I use the server to record CCTV images from a camera mounted at the back of the house, so having a power back-up system is a good idea. Rather than going the usual route of using a standard mains voltage UPS converting AC-DC-AC then back to DC from the server PSU. I thought I'd get and try out the picoUPS and a picoPSU from minibox.com. Since my server uses a low power Intel Atom mini ITX board i thought it would maybe save some power, because no power conversion would be needed.

Here's the picoUPS-100 from LinITX.com and a picoPSU-80-WI off ebay. From an Mini-Box authorized reseller!  (I colour coded the spade connectors with red and black maker pens)
