A late #Hackster round-up today, as everything seems to have been pulling my attention in about 15 directions this afternoon.
First up, Vitaly Puzrin's teeny-tiny little hotplate for solder reflow work (and any other task that involves heating small things up to set temperatures) - permissively licensed, controlled via Web Bluetooth.
Then a #crowdfunding campaign for something I desperately want: an acoustic camera. You know how thermal cameras let you see heat? Yeah, well, this uses a microphone array to see sound.
Can't justify dropping $900 on one, though, even if that *is* a lot cheaper than the $18,000 FLIR will charge you for their version...
Something for the computer vision crowd next as STMicro teams up with Leopard Imaging to develop a three-in-one smart vision platform: RGB and IR vision, lidar depth-sensing, and an integrated IMU for motion detection.
And, finally, a neat trick for using an MSLA 3D printer - the ones that work with UV-curing liquid resin - to print directly onto plywood for slick-looking tactile front panels for project boxes.
Just.... watch that stuff, 3D printer resin is *nasty*. Gloves, mask, and pay attention to the bit about soaking the wood in IPA, scrubbing it, and rinsing it off afterwards.
And yes, that *is* all available - as always - ad- and tracker-free via the #GeminiProtocol:
