Nearly everything has WiFi these days. [glaskugelsehen]’s Sony camera uses the wireless network to transfer photos to the computer, naturally, and it also has a remote-control application that’ll run on Android smartphones. [glaskugelsehen] doesn’t have an Android — but he does have shows us an ESP8266 that he turned into a WiFi-powered remote for the camera (Google translate into English).
Sony actually made [glaskugelsehen]’s work easy here. They have a publicly available API for the camera’s controls, and it’s all run by JSON sent over HTML HTTP POST. Which is to say, that it’s a piece of cake to script as long as you can send HTMLHTTP directives.
[glaskugelsehen]’s code, written in the Arduino environment for the ESP, first finds the camera’s WiFi network and authenticates to it. Then it sets the camera into remote-control mode, and takes over from there. So far, he’s only implemented taking still photos, but from the API it looks like you can also stop and start video recordings and more.
And yeah. We just wrote up another project doing virtually the same thing with a GoPro. [glaskugelsehen] read that too, and mentions it in his blog. We love it when people take inspiration from each other!
Unwilling to permanently modify his DSLR camera lens and dissatisfied with after-market lens gearing solutions, [Jaymis Loveday] learned enough OpenSCAD to generate gears from 50mm to 100mm in diameter in 0.5mm increments for a snug friction fit. Teamed up with commercially available focus pulling equipment, these lens gears should really help [Jaymis] get professional results from consumer lenses. 
nside the gates, we ran into [Tommy Mintz] who was showing off his
