1. Just scored a Sharp XR-30X DLP projector for $40 on Craigslist! Needs a bulb. ($55) I may dig into the electronics and see about bypassing the bulb sensor and use a 20W UV LED with mirrored reflector. Ebay has the reflectors specifically for the 10W form factor LED.
Has anybody ever found any data on the watts of UV that come from a projectors 250W bulb? I'm wondering if 10 or 20W from a UV LED is actually less than the mercury bulb produces.
2. 1 x Adafruit Raspberry Pi B+ / Pi 2 / Pi 3 Case - Smoke Base (w/ Clear Top)
[ID:2258] = $7.95
1 x Raspberry Pi 3 - Model B - ARMv8 with 1G RAM[ID:3055] = $39.95
1 x 5V 2.4A Switching Power Supply w/ 20AWG 6' MicroUSB Cable[ID:1995] =
$7.95 (All from Adafruit.com)
3. 1 x 3D Printer 1pcs Mega 2560 R3 and 1pcs RAMPS 1.4 control panel and 5pcs
DRV8825 Stepper Motor Drive Carrier Reprap (WER-U-0065) = US$24.30 (from Wercan.com)
All the information you need to load the arduino and make connections is available at mUVe3d.net
And at nanodlp.com
I haven't quite figured out what the advantage of using the arduino and Ramps board is, since the nanodlp can provide the step and direction bits for all of your steppers. And it drives the shutter.
The nanodlp puts out the images to the projector over its HDMI port. If your printer doesn't have HDMI, you can use an HDMI to DVI adapter cable.
