This past Tuesday, Jeff Jensen, a long time friend of OMG was at our regular meeting to get some help with mechanical assembly and soldering of a dozen CEENBoT units. Jeff is part of a program that develops the CEENBoT robots for education and the program has been so successful that Jeff is overloaded with requests […]
For years, our makerspace has used a hodgepodge of solutions for storing members’ projects in progress and other personal belongings. Most recently, we’ve used a dozen or so plastic totes. The totes worked great, but were limited in quantity (they were industrial waste, and no more matching totes were available) so that not everyone could

A while back, we decided that we needed a 24v power source for various “testing” applications. This source needed to be durable enough for daily use by a wide variety of people without becoming damaged. It also needed to protect the device being powered, and be easy to maintain. Given that tall list, Ben suggested

I have been flying my tricopter around lately, and getting a bit better at not running it in to things. But one thing in particular has been bugging me about the controller that I have. The throttle stick resolution seemed really low, especially when compared to a friends, much newer and nicer controller. When flying […]

On Tuesday night, we were disassembling some old printers, and salvaged some large ROM chips. Patrick got the idea to use the mill to remove the top layer of the case, and expose the IC inside. Â Here are some photos we took of the chip’s insides with a microscope. Magnifications range between 4x and 40x,

One of the other projects enhanced by the Variac is the vacuformer. Â It consists of two parts: a box with a heating element that melts plastic (background) and a perforated box which sucks the softened plastic down over a heat-resistant form (foreground). Â Prior to the Variac, we’d had problems damaging the plastic sheet, because it

The Makery’s recent acquisition of a Variac has rekindled interest in a few projects that had been on hold. Â One of those projects was the Acrylic Bender that James had been working on. At it’s core, the bender is just a halogen bulb between two aluminum tubes full of circulating water. The idea is to
At the Makery lately, Brandon and I [with some help] have been working on a CNC Hot-wire Foam cutter quite a bit like this one. Ours is going to be a bit larger, capable of slicing up a 2×4 foot piece of foam (actually, the X is more like 5 feet than 4). For our […]

Its amazing what you can print these days. We tested out the Mendel Prusa last evening by printing this cool little light bulb sculpture. If you could make any design in your head come to life, what would it be? Much of what we can do these days with 3D printing is due to the
