The circuitry for the electronic mural I made in the first two weeks of January (final product post here) was simple. I used three types of circuit stickers: an LED sticker, a sound sensor sticker, and a micro-controller sticker. Each sticker had the required components embedded, such that I just needed to connect everything. The challenge of the mural was not in the circuit design … Continue reading Electronic Mural: Part I
For the first two weeks in January I worked tirelessly to finish my electronic mural, which had been stewing around in my mind for months. I had tested the circuit on paper successfully (read about it here) and started ambitiously a mere two weeks before I was leaving the country for a long trip. My plan was to use Chibitronics circuit stickers and an Electroninks … Continue reading Electronic Mural
I now have three of my peristaltic pumps out in operation — two are pumping cyanoacrylate in a factory in New Hampshire, the other is pumping beer wort in my office as part of a continuous brewing project my coworker has set up. To pump the cyanoacrylate I eventually had to swap over to polyurethane tubing. The silicon tubing (which is generally what you … Continue reading Peristaltic Pump Update
A coworker of mine wanted to make some cool business cards and suggested making an insert mold for our injection molder. Apart from the fact that I don’t like the idea of injection molding business card, it got me thinking about cool business cards I *did* like the idea of. I’ve been toying around with the idea of making custom gliders with out logo on … Continue reading Business Card Glider
I have designed and built some peristaltic pumps for pumping cyanoacrylate (i.e. super glue). The stuff is about as viscous as water, and I want to dispense it in tiny drops. Peristaltic pumps are perfect for high pressure, low volumetric flow systems, plus there is the added bonus that you can easily replace the tubing if it gets clogged (i.e. the super glue dries out, which … Continue reading Peristaltic Pump
I’ve been very busy with work, hence the dearth of posts. However, I have been doing and making a lot of interesting things, so I have a number of posts lined up. This one is about a timelapse video I made of my company making our first shipment of our baby monitor, specifically the onesie that senses a baby’s breathing. We (all the engineers) planned … Continue reading Timelapse
