Briand354 tech blog: Raspberry Pi model B+ DVR / NoIR

Hello again,

Here is my raspi model b+ NOIR _ DVR

It took me a bit to source the parts, but here is what im using, if you wanted to replicate this config :

waveshare RPI display 3.2 tft [$18/ebay]

raspberry pi mobel b+ [$35]

generic tranparent case [$3]

NoIR camera module [$25]

camera module case [$10]

extras: usb flash disk, edimax wifi-n

After getting everything connected, and working once, using the raspbian image,

I then put the tft screen on the device, and began the config.

In this pic i am using a sandisk usb stick. It was replaced with a mini usb flash [barely visible on the left side, same size as mini-n wifi adapter]

I then drilled into the top of the case, for the camera mount. It has 2 screw holes for mounting on either side. I have 1 screw in tight, the other lose, and easily removed. that way, i can still swing it 90 degrees, so I can use the hdmi adapter, if needed. [ssh into it is easier]

This design took a bit to come up with to work as expected.

I have the recording being display on the tft screen as is it happening .

That was my intent with this device, similar to a real camcorder.

I was also thinking about jamming a small spinning disk into the case, but that could be a later mod.

at this point, I would like to see how it performs in the field.

But, i see this as a long term solution, and easily accessible for anyone .

When the dvr is powered on, it starts to autorecord [takes 10mins to start] from boot [based on a script] , and then records, and outputs to the usb flash - which could be removed after converting the .h264 files to mp4.

So far, overall, i am very happy with the end result. I will probably tweak it more, going forward, but its a great little setup for what i need it to do.

Let me know what you all think.

thanks,

Brian
