Or you could try salvaging faulty switches or other existing rackmount equipment.

Re: Looking to buy an R/C car to hack

Have a look for the Dagu Rover 5 tracked chassis, it can be bought in various states from "bare" with nothing to motors & encoders. I think both ProtoPic and CoolComponents have them in the UK.

Re: Adapt RPi camera to round cable (not flat flex) ?

Good point, those CSI signals are up to 208Mhz according to MIPI's CSI2 (I believe the RasPi is a CSI2, at least) interfaces. The fastest PATA133 ever went to was 70MHz (133MB/secs / 16bits) but CSI is a serial interface, so it *should* be more resilient than the old parallel interface. I guess I ne...

Interesting, it is incredibly simple to make those IDC cables round as well, as anyone who has hotrodded thier PC will know :) Especially as BitWizard provide the cables unterminated making adding the techflex nice and easy.

That's a cracking case for the Pi, plenty of room for expansion and other toys. Nice! As I think others will also wish to re-case Pi's into classic hardware, people should investigate cleaners/whiteners such as retr0brite or other cream peroxides to restore their former glories. Caveat, these are ch...

Re: How to emulate this tracking system

How much resolution in the video do you need? Also the motion of the platform will not be smooth with simple servos I am all for cool projects, but the simple way off the top of my head is to record the video as a wider shot and then just window in on the teacher at the edit stage.

Re: New Project.. Is it possible?

You should be able to squash that video feed down to about 4Mbps and still have it look reasonable.

Also the "easy" way is to host a web page with the video and then use the pi to update the status of the page for a "hit" or a "miss".

Re: Raspberry dashcam wanted

Really? Sounds quite high for 10 mins, I guess that's almost raw with very little compression.

I was shooting for like 4-6 mbps for 1080p30 H264, is it just your settings or does that level of compression compromise the quality?

Re: Length of camera cable

As I was out of the country, I managed to miss the CPC order frenzy (soon gadget, soon.....)

Is it a standard n-pin ribbon cable? I think a short 75mm cable would be better suited to sticking to the front of a case without too much excess getting in the way.

With the help of this guide I managed to get my serial GPS unit to start spitting out GPS NMEA sentences to the terminal. The issue is it is a 4800 baud device, which I can open with ttylog or screen, this seems to "set" the baudrate. I can then do cat /dev/ttyAMA0 >> log.txt Until reboot at least. ...

Re: Image stabilisation

I do hope that work on this is continued. Image stabilisation done at time of capture, even electronic like this is usually superior to attempting it in post.

Of course the reverse is that if the software gets it wrong, it's harder to fix it in post.
