This is a project that I d been planning on doing for the last 8 years (and I ve even had most of the part waiting on the shelf for that long). It all started shortly after I got the SIEG milling machine back in 2014, when I ran into this page on macpod.net describing how to Read More
I ve very rarely done any threading on my lathe. Changing the gears was always way too much of a pain, which meant I used a die whenever possible and left the gears permanently setup for feed. So after Youtube started recommending videos from Clough42 s series on his Electronic Lead Screw project, I was inspired to Read More
This year s Google CTF was held over the weekend of the 22nd and 23rd of June, which for me was terrible timing. First it ended only one day before I was off to Glastonbury Festival, so I was a bit distracted by planning and packing for that. Then I also had a hospital appointment on Read More
On Sunday I happened to notice that Google have taken down the challenges from their 2018 CTF competition, replacing the site with a notice about the imminent arrival of the 2019 one.

I ve got a crazy idea for a new extension to my HDMI Light project I ll save the details for another day, but it will only work if I can accurately find the position of many small objects. I d considered a few options, but as I ve got an HTC Vive VR system, I thought I might Read More
One of the reasons that I ve not posted anything new recently is that I ve been learning to play the guitar, and now that I ve got to the point where I can play some almost recognisable songs, I wanted some accompaniment and bought a cheap electronic drum kit. I took the cheaper option and got a Read More
Recently a question came to me from a friend of a friend they had a globe that displays text messages that they wanted to use as a Christmas decoration, the only problem was that they couldn t change the message because it was password protected could I unlock it? Hmm maybe bring it round and I ll Read More
One problem with my HDMI Ambilight project is that it can t handle encrypted content, or more accurately, it can only handle encrypted content if I spend a lot of money and get an HDCP license, which would then allow me to buy the version of the ADV7611 chip that has built-in HDCP keys.
