Inside the TI Pico Projector development kit
I just HAD to buy one of these when I saw it at Digikey....! Not yet sure exactly what for yet, but it's so cool it had to be done.... And taken apart of course.
Micron chip above possibly RAM for frame buffer
Winbond EEPROM 25X16
TI DLP processor chip
Bottom-right probably power supply, marked BYK
Bottom-left marked 7BDS
Copper LED heat spreader to right - a thermal pad (removed) transfers heat to the case.
Small IC Probably power supply, marked BYK
Underside of processor board
MSP430 processor M430F2232.
Other IC probably power supply, marked BKA TI 81 ZC3W.
Warning - inter-board connector is very tight - gentle rocking appears to be the best line of attack. I initially used a screwdriver to lever apart, and mangled a resistor (bottom-left), causing the LEDs to stop working. Replacing it with a 10K seems to work OK.
Underside of DVI board
LED driver. IC to left marked BPT 87K - connected to power jack - probably main PSU regulator
Q1/2/3 probably FETS to select R/G/B LED.
Rear of LED flex with heat spreader removed
I wonder if this would concern the more security-paranoid people out there... I can just see the headline - "last slide of top-secret presentation found on projector bought from ebay....!"
Rear of DLP chip. Connector soldered directly to rear.
DLP mating connector
Front of DLP showing image
Shining light 'backwards' through optical block indicates
some sort of filter or dichroic mirror arrangement inside to combine LED output..
