Pseudonymous Lithuanian maker “Atominis Sumuštinis” (“Atomic Sandwich”), hereafter merely “Atomic,” has constructed a “poor man’s Polaroid” — by combining a Raspberry Pi single-board pc and digicam sensor with a thermal printer initially designed for receipts.
“That is an instantaneous digicam that makes use of [a] thermal printer to print pictures, the identical one which prints your receipts on the retailer,” Atomic explains of the undertaking. “Pictures aren’t the identical high quality because the self-developing movie that Polaroid makes use of, however they do have some, uhh, attraction to them, I suppose. [The] title is perhaps a bit deceptive although: after I name it ‘poor man’s,’ I imply ‘enjoyable DIY undertaking, probably made by poor fingers,’ and never an affordable digicam, for the reason that elements value me greater than the most cost effective Polaroid.”
The elements might value greater than an precise Polaroid digicam, however the prints are low-cost: slightly than full-color self-developing movie, which might value upwards of $1 per picture taken, the digicam outputs to low-cost thermal paper — with the draw back being, after all, a restricted decision and solely black and white because the out there colours.
Contained in the digicam’s 3D-printed housing is a compact Raspberry Pi Zero single-board pc, related to a low-cost digicam module. “Some may say this [is] overkill,” Atomic admits, “[but] I say that is what I had readily available.” Elsewhere within the case is a dismantled USB energy financial institution — “one way or the other rather a lot cheaper than shopping for [the] similar elements individually,” Atomic explains — and a low-cost thermal printer initially designed for printing receipts from a point-of-sale system.

“[The Raspberry] Pi digicam is first rate,” Atomic says, “however typically the image is simply too darkish, different instances there’s an excessive amount of gentle. Due to this, within the code […] you’ll be able to see a bunch of features which alter the image relying on it is brightness. I’ve found out when to make use of which adjustment by trial and error.”
The undertaking is documented in full, together with Python supply code, on Atomic’s weblog.
