How-To: LED Photo Lights

What do you use to light small objects you’re trying to photograph? MAKE contributing editor and author of the bestselling Make: Electronics book Charles Platt found that electronic flash is overkill and photo lights are too bulky and hot, so he built an array of miniature LED photo lights and shared the how-to with us in MAKE Volume 34.

All About the Diode

All About the Diode

Collin Cunningham explains what diodes are all about, describing the history of the component, the various types, and even touches on creating your own.

Or will we look back one day and think that these fabricators represent the beginning of something entirely new, and we might consider 3D printer such as MakerBot the start, not the end, and that’s there’s generation of 3D machines we haven’t seen yet. Maybe we should have been calling them something other than printers, a better name such as “fabbers.”
