Nerdy Derby Wheels Keep Rolling!


We’ve been printing wheels… lots of wheel! We tested some at Madison Mini Maker Faire’s Nerdy Derby event last weekend, and we’ve been using Son of Megamax to crank out little plastic wheels.


Yes, we are printing 37 wheels at a time! And we’re using ABS filament from CoEx in Appleton, Wisconsin. They were kind enough to supply us with some spools of filament to keep SoM busying printing pretty much day and night!


I know you’re wondering how we keep an eye on all those wheels being printed. Well, when we’re not at the space we just check out the Milwaukee Makerspace Webcam. (As long as it’s pointed in the right direction.)

Sunday Morning Project – A 3D Printed WebCam Mount for a Telescope

I recently acquired a new eyepiece to replace the damaged one that came with the Meade ETX-90 telescope I bought at a swap meet last year.  I decided it needed to have a web-cam mount so I designed and printed one that is a variation of a previous design for a microscope.  It took about 20 minutes to recreate the CAD file in DesignSpark Mechanical, and about 90 minutes to print on Son of MegaMax.

This thing has an odd shape to accommodate the odd shape of the camera.  I designed the adapter in two pieces so it could be printed without any support material.  After printing the two pieces were glued together with a little super glue.

The adapter fits over the barrel of the 32mm fl eyepiece and stays put.


I shot a short video to test it and it works perfectly!  The cars driving by are about 1/2 mile away.


If we ever get a clear night I’ll try shooting Jupiter or Saturn and then run Registax to enhance the images.

CCTV Progress

Thanks to the efforts of Jack, Royce, Tom, Ross, and I, the CCTV system is finally working!  Zoneminder’s been set up and we plan to have 12 cameras total when finished.  The goal is to eventually broadcast them all to the website here so visitors can see who and what is going on at Milwaukee Makerspace.  Stay tuned!
