Masterpiece Mania is a yearly electronics competition held by the IEEE student electronics club at Michigan Tech. The goal is to make the most interesting, creative, and entertaining project. A panel of judges decides the winner. This year, the event was sponsored by Whirlpool.
In what looks like a plain brick building from the outside, has a treasure-trove of equipment, people, and ideas inside. The Hack Factory, located in south-east Minneapolis, is the location of a group called the Twin Cities Maker, a non-profit. Continue reading “Touring the Hack Factory Makerspace”
I found a solution for my audio quality issues in my videos. I purchased a Neewer NW-700 microphone which included a shock mount. I also purchased an XLR microphone cable and a pop filter. The only thing I was missing was a microphone stand.
The crucible break detection (CBD) detects if the crucible has broken and shuts off the induction furnace. It accomplishes it by having two parallel metal plates underneath the crucible. If the crucible were to break. the metal would pour out and short out the coil. An electrical circuit will then shut off the relay that provides power to energize the 3-phase contractor and thus the entire work coil driving circuit.

This video is just a quick overview of the open-source induction furnace design I have been working on for the past year.

The Tektronix CFG250 2MHz frequency generator was sold as non-working. When I tested it, there was no signal output from the generator for all the waveforms and frequency ranges. Continue reading “CFG250 Frequency Generator Repair”
*NOTE: This is not a final design yet*
I along with a team started this project in the fall of 2014 and it is almost complete. The goal is to melt aluminum and steel for researching metal alloys. I don’t even know where to begin on this project because there are so many parts and systems. I guess I will start with a block diagram. This design is based off an instructable by Bayley Wang.

This second version of the led driver will improve the design of version 1.
The Zebra LP2844 thermal label printer is a good addition to any electronics lab. It is really easy to print labels for component drawers and projects. It is a 4″ model that can print shipping labels too, great for Ebay. The 203DPI print head is adequate to print labels, although there is some blockiness to them.
The LED driver is made specifically for driving 100W LEDs. I couldn’t find another driver that fit my needs online. I needed something for an affordable price that was dependable. I would need to buy about 8 units.
