This 3D-printed DIY digicam contains interchangeable lenses and sensor: Digital Pictures Evaluate


Electronics engineer Gaurav Singh has created an open-source USB 3.0 digicam. Higher nonetheless, the compact digicam makes use of interchangeable lenses and sensors.

As described at, Singh’s digicam design incorporates a pair of major boards, one for processing, and the opposite USB, which drive a 3rd interchangeable sensor board. You’ll be able to simply swap out the sensor board, so the digicam is versatile and will be tuned to your wants, as long as you discover elements that can work with the opposite elements.

Since Singh employs a stacked board design, the digicam additionally has a small footprint. Every board is 27 x 27mm, and the digicam is basically a dice. The USB controller board communicates along with your PC, and the sector programmable gate array (FPGA) board handles the processing to permit the USB controller board and picture sensor board to speak. As of now, Singh has one digicam module PCB designed. It is appropriate with Sony IMX290, IMX327 and IMX462 picture sensors. These sensors have the identical decision – round 2MP – and footprint. These are all 16:9 facet ratio Full HD decision 1/2.8″-type sensors, with a diagonal of round 6.45mm, giving crop elements of 6.7x.

As DIY Pictures writes, ‘It is a pretty concerned mission, with every of the PCBs being six-layer boards to deal with the quantity of complexity they should take care of in such a small and compact measurement. However these three tiny PCBs all match inside a 3D printed case with an aluminum thread mount on the entrance for mounting the lens and a gap within the again for the Sort-C USB connectivity for energy and information communication.’

Whereas Sing has designed the digicam primarily for industrial use, it could possibly be used for different functions. It could possibly be used as a webcam, or with some modifications, you might use it for gathering time-lapse picture information or as a path or surveillance digicam.

For the reason that mission is open-source, all of the required recordsdata can be found. On Singh’s web site, you will discover recordsdata for the PCBs, and 3D printed elements. The code to energy the digicam is on the market on GitHub.
