Scary vampires

April 7, 2010

After looking at some rubbish web cams which claim to have night vision capability (and actually only have LEDs to light up when it gets dark) I decided to go with a really cheap one from China (through eBay), just in case it turned out to be one of those.

It’s a very small camera which even has a mic,  and works surprisingly well for just £3! It works using Infra-red LEDs allowing it to work in the dark. I was quite sceptical of the quality of the image so naturally I tested it with different variables.

I turned the lights off and only had the light coming from my laptop screen at first and it worked great. I then placed the camera facing away from the laptop (completely behind it) and it still worked well. I stood in front with my little sister and it made us look like really pale vampires with scary shiny grey eyes! We both have dark brown eyes so not sure why that was happening. Anyway, the point is it works and when I use it for my work it will actually be mounted overhead so the problem of looking like scary vampires won’t be an issue.

I then tried to get it working with the OpenCV and processing examples on my PC but to no avail. I keep getting error messages. This is a major annoying factor, but one must persevere! I just have to keep trying to figure it out.

OpenCV - Errors :(

OpenCV - Errors 😦

I have also ordered a large roll of mirror card. It took me some time to track down someone who could sell it to me uncut (as the largest sizes you can get in the shops is A2). This gives me loads to experiment and work with and was a good saving on the usual retail price too.

I have also been looking into metal-cutting companies who not only supply but provide services for cutting metal sheets (aluminium, steel etc) but seem to be doing this mostly on mass scales. Its been another difficult aspect of getting the practical work together but I’m still hoping it can be done as a one-off and at a reasonable price. I’m now waiting for those companies to get back to me with quotes.

So all in all there are many small things going on but all are necessary in order to produce the whole which is probably why I haven’t been blogging as much.

My next task is to choose and complete a final pattern. I want to up the game a bit with this and choose a more complicated one that combines possibly 10 and 5 fold arrangements or 12 and 6. Plus I want to add my own touch to the standard pattern formations. It’s not a huge requirement but would be a nice bonus.

I am also aware that I had set myself the goal of having a proto-type ready by the end of March. Unfortunately there have been a huge amount of things to do which has slowed my progress down. And more things keep coming up! I do sometimes wish I could work on this project full-time but then again the other things going on are not bad things or are things that are about progress in life in general and so I wouldn’t sacrifice those either.
