Garden Light Ideas | Custom Globes for Solar Lamps

In this build video, I design a 3D printed globe for some inexpensive garden lights and give them a custom look. The build didn’t go exactly as planned, but check out how things turned out!

What was the other design supposed to look like? Well, I was going for a Rougier Tube Lamp style. It turns out that I miscalculated the diameter of the straws needed to completely cover the surface of the solar lamp. To make matters worse, the glue I was sure would work had some sort of chemical reaction with the straw plastic, and wouldn’t bond. It just turned into a disaster. I don’t think this will be my only attempt at making that style of lamp, but it just didn’t work out for this project.

That was my project day!

DIY Halloween Decorations: Animated Skull

In this build video, I show you my Animated Skull project. Using a servo, some 3D printing, and some clever circuitry, this inexpensive Halloween prop can automatically move in sync with recorded audio!

When Halloween gets closer, I’ll post more pictures of the final dressing.
