I started with the idea of not using any kind of electronics and just have a contact breaker to make the coil oscillate. My first experiment with that setup worked well but the contacts just kept wearing out and the coil stopped oscillating within a...
The IEVS Bern Silicon Valley Hack- and FabLab is a Hackerspace Club of experienced information technology experts and internet professionals.We are a collection of hackers, programmers, builders, makers, and artists. We promote science, technology,...
Before the original Guardians of the Galaxy even hit theaters, I had started building Groot as a cosplay costume based on screenshots of the many trailers going around. I missed the opening date in theaters and then the project got stalled...
Continuing from the desciption:This version just takes a reading, flashes out the rounded-up UVI on the LED, and then goes back to sleep.A side-view, 350 mca, true-green LED was chosen for maximum visibility in full sunlight. Side-view is used as the...
Project Components: Wipy 2.0/3.0 x 1 buy WS2812B 100 bits LED Panel x 1 buy Jumper Wire x 1 buy Xmas-lights x 1 download The Wipy2.0 is not available any more, but the WiPy3.0 should be better (it has more RAM) and it should be pin-compatible with the...
The Siemens heating system is meant to work with intermittent electric power to take advantage of lower electric rates. The prior controller was analog, and used a capacitor to average outside temp and control the heaters. The heaters were...
The microcontroller does the things the PC does not have time to do, namely monitor the RDS clock and data signals.The first step was to write some RDS decoder software code in plain C for a console application using stdio, which is much simpler than...
Boian Mitov will be hosting the Hack Chat on Friday, May 25, 2018.LINK TO CHAT ROOM Time Zones got you down? Here's a handy time converter! Connecting hardware modules to Arduino and similar microcontrollers is easy and most makers have no...
What's this? I have seen a video about the Creative Labs Prodikeys range of products - these are computer keyboards with a row of piano keys attached to them. I instantly wanted to have one. (More info on these weird things) Unfortunately,...
After failing to map the pinouts to the Priv's combined keyboard/trackpad, I decided to use a keyboard off a Q10, due to the decent amount of information available. Using a Hirose BM14B connector soldered onto a PCB (and this, ladies and gentlemen, turned...
I used Arduino pro mini as controller for this project, small, cheap and simple. Enough pins event for further modifications/upgrades. 3 tactile buttons are used to set up main settings like temperature range, heating speed, lights animation speed and...
During the Winter Quarter of 2018 at MSTI / UW, my team developed MYHouse, a smart interactive doll house that people can interact with by moving a “magic wand” in the air to make it perform certain actions. The dollhouse was...
Train sets are great. But you know what else they are? Expensive. And, sometimes, a bit snooty. For me a train set is no fun if it isn't automated, and I am not interested in realism or historical accuracy. And I don't want to drop thousands. But now...
In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which...
I start off by designing the board in EasyEDA. As there are no premade footprints available, I had to make my own. I did this by modifying a regular footprint. I first make the pads square and move them outside of the PCB. Then I made a cutout in the...
