Discussing possible designs
04/17/2016 at 02:48 • 0 commentsCame up with two possible designs:
1) Raspberry Pi approach:
- Raspberry Pi Zero - $5
- Simple WebCam - $2-10 (could use old donated ones too)
- PIR sensor - $1.5
- Micro SD card (4gb probably enough) - $2-3 ?
- Battery
- Case
- Optional IR lights
Pros:
+ can connect to any WebCam (or any additional tools if necessary) via USB
+ can be connected straight to a monitor for analysis later
+ would not consume too much battery power
+ can be programmed to stand by (save energy) when there is no action, and woken up again to take the picture
+ easier to reproduce and build yourself+ can program anything on Linux
Cons:
- difficult to get Raspberry Pi Zero
- would take time to program on Linux2) KeyChain Camera approach:
- KeyChain Spy Camera - $5
- Arduino that controls the PIR and Camera - $2
- PIR sensor - $1.5
- micro SD card (4gb probably enough) - $2-3
- Extra battery
- Case
- Optional IR lights
Pros:
+ cheap parts
+ easier to get the parts
+ there are also better KeyChains with motion detection
+ easier to program
+ uses less battery life
Cons:
- would need to install a bigger battery
- requires soldering
- photo resolution not so great
