Just dicking around with a weird old predecessor to flatbed scanners. Enjoy! Donate to my channel: ko-fi.com/gravis Patreon: / gravisvids

I had one of these in my younger days. It was much cheaper than a flatbed scanner (at the time) and you can do larger images with photo stitching software providing you were careful during the scan process. Overall decent quality for its size however it got quite cumbersome scanning larger images so I caved in and purchased a flatbed a year later. The passthru parallel port was for printers (obviously) and it was about a year or two out before USB started gaining traction.

Thank you! I've always wanted to see how well these things worked :)

I appreciate so much that you ran the scanner over pretty much every surface within arm's reach.

Cool stuff, one of those things that was always on my wishlist but I never actually got to play with, too.

You are a true artist, consider selling these. 🧑🏻🎨

Glad you made this video so I don’t have to buy one just to re-experience it

I think Logitech were pushing this type of hand held scanner over a rotary type feeder scanner simply because it was lighter and more portable. This supposedly made it attractive to business men "on the go". I'm not positive that was the intent, but I seem to recall them advertising these things a lot in Office Depot back in the day and that was the intended appeal of them. PS: I LOVE what you did here with all the experimentation. This makes it quite attractive to digital artists who want to capture some abstract stuff.

not ideal for its intended use case but still tons of fun. The inescapable urge to scan any and everything around you, its like labeling things after buying a label maker

well the comparing voltage part in that thing usually works with a zener diode and an op amp comparing the zener voltage with the supply voltage and then regulating a transistor accordingly in a feedback loop

Thanks for this video, it brings memories back of my old Mustek (?) Handy Scanner! :)

i think just about anything that has an "internal reference voltage" is using a zener diode; those magic bastards that shunt all excess current such that the voltage drop across them is ALWAYS whatever the zener is rated for. i mean technically all diodes do this with the standard 0.6v drop or whatever.. so u could make a reference voltage of 0.6v with a regular diode... or put a few in series for whatever multiple of x0.6v you want. you have to feed them with a resistor so its not a short circuit. +V...[resistor]....*.....[zener]...GND where * is your stable reference voltage output. NOTE that zener's special breakdown voltage happens in reverse, so they always look like they're wired in upside-down. finally, this "reference voltage" is only meant to source infinitesimal amount of current, to be used for an opamp or something... trying to use a zener directly for voltage regulation CAN work, but for any meaningful current you have to choose a very low value resistor which will catch fire :P (o and also, i think voltage regs like 78xx basically have [ref volt]....[opamp]....[transistor] where the transistor is run in forward-active mode so it acts as a variable current amplifier rather than a switch... thus, the heat generated in a voltage reg is actually from the transistor)

okay you redeemed yourself with the phone light scan.

I got to play with one of these in the early 90s. It was cool but you had to be super steady.

I had the ISA version in a 486 dx 40 with just 8 mb of ram. It sucked because of the computer crashing and sadly never got to use it with our newer Pentium 133 mhz and 32 mb ram because of win 95/98 driver software. you wouldn't happen to have the drivers for the ISA Logitech Scanman Color???
