This week on Maker Update: a necklace with a staring problem, a laser powered mosquito swatter, moire play, and a giant 3D printed mechanical hand.

This week on Maker Update, a wheel-y cool weather bot, a call for maker music projects, freaky fractals, making monsters, and drawing with the PlottyBot.

If you do any soldering you probably have a pair of helping hands, or some bulky heavy thing like this that can hold your project or components steady while you wire them. They’re useful, but a little clunky to travel with, and often overkill if you’re just splicing a wire or two.

This week on Maker Update, Pterodactyl automata, a tachometer for your tools, poster tack for your tech, Hackaday Superconference, understanding screws, and making better projects. This week’s Cool Tool is poster putty (really!).
