I had a My-Effect for digitizing in my suitcase for a while, when I was on the road for a year. Bought it at a Spenser's gifts in Bozeman, Montanna. I was stuck in Bozeman for two weeks on business. Only downside is the laser diode drivers cannot be easily hacked to an ILDA connector. They use weird -1.3 V current sinking logic on the microprocessor color outputs. That and 100 mW of IR in the green on mine. However the scanners were, well, decent, for such a simple, low power, scanner amp. You can hack the scanners to a ILDA connector, but the diode drivers were not hackable, and I spent a few hours trying on the bench with level shifters and a very good digital waveform generator.

DOG-P couldn't hack the RGV either..

You also cannot set the diode currents easily, it uses a tiny 406 sized SMT fixed resistor to set the current. The diode driver is a Chinese 100 mA LED driver chip with On/OFF, and the DPSS green one is three such chips in parallel. Its not TTL, its a current sink, and not to sinking to ground, either. At least on mine. The Diodes default to on if you disconnect the microprocessor.

Two boards inside, microcontroller and diode driver on one, scanner amp is the other. Power comes from world's largest wall wart, which is more like a laptop psu.

The color dichros are hot melt glued down on a thin aluminum plate, no mounts.

I liked it, it did a good job for a miniscule projector with a 405 diode for the blue, a 670 nm diode for the red, and world's crudest DPSS green. Not too much problem with tails on the green, either... Speeds, file sequence, and repeats are a ASCII text file that is not hard to edit. No on hacking the diodes, really pressed in hard, and overcoated with epoxy.

The bitchin part is how to figure out how the 8051 derivative used as a controller guesses what is blanked, violet, white, green, red, or yellow. That is going to take a lot of experimentation.

I'll spare you the time and post the SD Card files as a zip here, tomorrow if I remember...

Not sure why you'd want to waste your money on one of these, the only thing well built is the power supply, and its not +/-24.
