Greetings Maker Faire North Carolina Attendees! It was fun speaking with many of you today. Here is a collection of links to bots and technologies that I spoke about: StickBot (the simple 6-legged walking robot) — the latest version, with schematics…
I built a framework for robot wheels a while back using OpenSCAD and used it to create a few different wheel styles. I recently decided to combine them all into one massively configurable wheel model, and add a number of…
Here’s a 3D printed T10 lamp shade that I designed and printed last night. A few weeks ago while searching for LEDs, I noticed an ebay listing for very inexpensive 12V automotive lamps that combine nine bright white LEDs. I…
OpenSCAD apparently doesn’t have an easy way to make an arc or wedge, or any way to do a partial rotate_extrude. This presented a problem when I started to design my Parametric Encoder Wheel, because in order for it to…
I received several filament samples from New Image Plastics in Ohio, ranging in length from about 1-4 feet. Here are the measurements I took from various points on each strand. I measured all the way around the filament and recorded…
When I wired up my Reprap and started printing, I noticed that all my prints were mirrored along the Y axis — I’d set it up with the end stop at the front and configured it so that the print…
A couple of people have noticed this, so I thought I’d write it up. There’s nothing wrong — it’s just something to be aware of if you’re soldering up a Sanguinololu 1.3a PCB. If you look closely at the circuit…
Yeah, free. If you’re starting a 3D printer project (such as RepRap) at your public K-12 school in the United States for the benefit of the students, then we’ll give you a free Sanguinololu v1.3a PCB to help you out…
The shipping “estimator” at Mouser.com is a little vague, so I thought I’d post the results of a recent order. In general, you’re not going to know the shipping cost or the weight of your order until after it’s shipped.…
I’ve set out to build a Prusa Mendel for $300. So far I think I’m doing pretty well. The top part is what I’ve already picked up, and the bottom part is what I have yet to purchase — that’s…
