GH5 Foot Pedal Shutter Remote

A DIY foot pedal shutter remote is an absolute must-have in my tabletop photography arsenal. The GH5 remote has a few resistors in it, which makes it a bit more involved to DIY than, a Canon shutter remote, for example. I looked it up, and sure enough, the switch contact is held high at about 41.1K ohms, and the shutter triggers when the switch brings it down to about 2.2K ohms. Resistor values add up when put in series, and some experimentation shows you can successfully deviate a bit on the resistor values (try what you have that’s close).

LED Mason Jar Lanterns

In this easy 3D printing project, we’ll build glowing mason jar lanterns containing a simple LED and battery circuit. Download my file or build your own custom lid using the Glow Circuit Assembly in Tinkercad, which is designed to hold the battery and LED together perfectly. I’ll show you four different ways to style your lanterns using materials you probably already have around.

3D Printer Filament Dry Box

This tutorial describes how I made a dry box for my 3D printing filament. It protects the PLA from absorbing moisture from the air, which can lead to failed prints and nozzle clogs. The dry box dispenses the filament to the 3D printer too, providing convenient storage.

This box fits four standard rolls of filament. This is an easy project that takes less than an afternoon to complete, and then you’ll reap the filament-preserving benefits for countless days to come!

You’ll need a gasketed plastic container that’s at least as tall and deep as a roll of filament, and as long as you want to accommodate your shelf space or filament collection.

Besides the box, you’ll need a piece of PVC pipe or closet rod to match the length of your box (I cut mine with a hand saw), some teflon tubing to feed your filament to the printer, some silica gel packets to absorb moisture from the air inside the box, a step drill and screw gun, some O-rings and screws (with appropriate drivers), and some 3D printed parts I found on Thingiverse.
