Classic Car Data Stream System (prototype)

 I have been a bit lax about putting stuff up here so this is just a link to a YouTube video showing the classic car data streaming system I have been working on in another format from this previous one.

Update on the touch monitor

-
This is tantalising... I found some data on driver chips used on these low-cost monitors and some of them have an I2C connection for sending pixel data directly to the screen. This may be to allow text or graphics overlay. Anyway the chip on my 7" screens is an AR05C-LF and there are millions of these in stock in the far east, but I can't so far find a data sheet for this chip or its sibling the AR05CA-LF. Being able to send digital pixel data via I2C directly to the screen would be, well, brilliant.

Apple iPad SSH Connection to Linux Laptop

I was given this older Apple iPad a while back and was looking into installing Linux on it. Options are limited, but it is possible to install a shell to the iPad and run command line stuff.  SSH is always a bit of fun so I logged into my Linux Mint laptop remotely for a giggle. It was interesting running a few simple commands from the iPad. My cheapo Bluetooth keyboard came in very useful although I discovered that the iPad's OS version predated mouse support so the trackpad didn't work. Going a step further, I got my Raspberry Pi going again and was able to install VNC on the iPad and remotely control the Raspberry Pi's desktop. Could be useful! I'm also looking at fitting a small heatsink and 5-volt fan (recovered from a broken laptop) to the Raspberry Pi and over clocking it to 1GHz.

Six Inches - Big Enough

I got around to taking the screen out of one of the LCD units to see what could be done with it. For a start the actual screen is 6.2" (according to the serial number and a ruler) not 7" as on the manufacturer's website, but that's no bad thing. It turns out a 6.2" screen is just the right size to fit in a double-DIN car radio slot, which prompts all sorts of ideas. It also turned out that there were 2 circuit boards, a big one with an audio amplifier and some power supply circuitry and a small one for the actual screen. Essentially the screen will operate with just a 4-wire connection (9 volt, GND, Video and Video GND). There is another connector for options (screen mode, colour and brightness), but with nothing connected to this the monitor defaults to perfectly use-able settings. In the photo I have it hooked to a PC via a VGA-to-Video adaptor. The computer is running Tiny Core Linux (my new favourite distro) in 640 x 480 mode (I think). It will go down to 320
