Still around folks! Just thought I'd say this blog is closed for the most part. Decided a while back to document any future projects over on my YouTube channel and a soon to be created Flickr account.

Sony Handycam Camcorder Repair: Re-Capping

Few months back I picked up a Sony Handycam Video 8 camera (CCD-TR333 circa 1993) cheaply off ebay. I brought it to transfer a load of family videos to the computer, for archiving to DVD. The camera was working but only in playback mode. It was very temperamental and would only play tapes ok after a few minutes of power on. The camera side was working but it would not record very well, only a wobbly picture with varying amount of static. Thankfully I was able to capture all our tapes ok with out the camera dying completely.

Getting antique video cameras working – Part 1

I acquired a two old early 80's video cameras to play with recently. An Hitachi VK-C600 and a Sony HVC4000P. These are the old type that use a tube as an image sensor. These cameras required to be connected to an external VCR to be used. As well as recording video from the camera, these also provided the power supply to run them.

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:
