 Anybody looking to buy a DLP projector and what to look for. 

For reference I just personally learned this while buying a used DLP projector for a SLA DLP 3D printer.

the things that can go 
The main thing is the bulb they have a life of about 2000 hours. They can cost any where form $25.00 USD used to 150.00 USD.

But also the DLP chip or chips can go they are a chip that has a bunch of tiny mirrors. if the unit has dead pixels it will need a new chip. Sone I have found only show pictures of the display so look for small white spots on the picture.
These chips can go for the same 25.00 to 175.00 the good thing is that most used unless they are bad will normally include a 30 day warrenty.  (plus I found bad DLP chips on ebay who would buy one bad?)

I just finished up BBHN-Pi-VPN  it has the VPN client and server settings in the web UI using HSMM-Pi and ZL1FLY's VPN code. This is to connect up Mesh networks that would be impossible to connect up with wireless. It also runs well on the Pi with no noticeable lag.
