3D Printed Rigid Heddle Loom

My wife Lisa and I recently got into weaving and wanted a larger heddle loom than the small one I bought her for Christmas. After a search on Thingiverse I found this excellent design from user ten16. It utilizes 3D printed parts and wood dowels in it’s construction and it can be built as wide and long as you wish. There were no instructions for assembly (other than a few pictures) so I thought it would make for a good step by step project video on my YouTube channel. 

Rigid Heddle Loom 

Here is a list of dowel sizes and lengths to build a 16″ x 30″ loom like the one in my video:

7/8″ dowels:
4 pieces 16 7/8″
2 pieces 2 1/8″
2 pieces 2 1/2″
2 pieces 30″

1/2″ dowels:
2 pieces 17 7/8″

7/16″ dowels:
1 piece 16″
1 piece 16 1/2″

60 #6 x 1/2″ counter sink wood screws

I used PLA for the heddles printed at 205C with a bed temperature of 70C and a 50% infill in draft quality.
All other pieces were printed with PETG at 235C, bed 70C, 20% infill except for the retaining rings and winding braces which were printed at 100% infill for extra strength.

I made a CyborgCam for Maker Faire

I’m going to Maker Faire Bay Area 2019 this week to give a Hackaweek presentation on Sunday May 19th.


I’ll be walking around all day Saturday wearing this CuyborgCam that I’ve hacked together. Hope to see you there!

Hackaweek Coast2Coast Episode 3 – Atomic Pi, solder fails, bad diodes, filtering farts, tweeting litter box

We had some good laughs on this week’s podcast. You can listen on SoundCloud, Spotify, Apple Podcasts and more. YouTube link below.

Here’s a few links to the topics we discussed:

Audio Man Is Finished!

After investing about 30 hours total time into this project I’m happy to say that it’s done and I’m really pleased with the outcome. Everything works and it looks awesome! As I  mentioned in a previous post, this build is for the Hackaday.io Circuit Sculpture Contest. I’ve entered it with two days to spare before the deadline. I’ll post the contest results here later.

Here’s a few pics.

Of course I’ve documented the entire build on YouTube. 
Here’s parts 2 & 3. Enjoy!

Audio Man Circuit Sculpture

This is a project I’m working on for the Hackaday Circuit Sculpture Contest.  I’ll be constructing a piece of functional electronic art built from copper wire and discrete electronic components constructed in the “dead bug” style of circuit building. A fully functional LM386 audio amplifier will reside inside the ribcage with eight hearing aid batteries in the spine for power. The head holds the speaker, input jack and volume control. Moving one of the arms in a raised or lowered position will turn the circuit on or off.

I’ve started this project by drawing out a sketch. The next step will be the basic construction of the skeletal parts then I can built the spine and head. I’ll Then begin construction on the dead bug LM386 amplifier which will be mounted in the ribcage and wired up to the rest of the sculpture. Finally the ribcage will be installed and the whole thing balanced by bending and tweaking the skeletal framework so that it can freely stand on its own.

Here’s the initial sketch. I’ll post more once I start building.
