Hardware setup expects an Arduino Micro with the following hardware attached:Big Dome Button hacked to support RGB LED, microswitch normally open pin connected to pin 12, Common Anode RGB pins connected to PWM pins 9, 10 and 11.RGB Illuminated Rotary...
STM32103RET6 ARM Cortex (currently, if i can't make the ADC behave and the SPI SLAVE to work correctly then going to flip back to the SAM7, which would suck a lot. (which we ended up doing for this round) ) I have still continued the STM32 build...
I'd always wanted a CPU gauge for my computer. Ok, and a bandwidth gauge for my router. You name it, I want a nice analog gauge for it. It always seemed a bit silly to use an true galvanometer based analog gauge for signals that are inherently digital....
Currently the project requries development in the following areas:CASUAL Core must be split into OS-Specific packages. UI work is needed. Monitization in-app is also a consideration.
All of us who work on Hackaday.io are reading your feedback. If we don't get back to you individually, know that we read what you wrote. Thanks for taking the time to give us feedback, we really appreciate it, you help improve the site...
Intending to keep this as compact as possible I'm looking at BGA packages for SRAM and std package for the SPI Flash. The several that I've chosen will enable me to keep costs below $30 for the whole board (target = $25) and still have head room...
The main controller board is an off-the-shelf Parallax Quickstart board. I designed and built a custom shield that provided a power supply for the project and driver outputs (TC4427) for the LED strings. Though we didn't use it, the board also holds...
Arduino reads voltage from voltage divider with standard 10k resistor and NTC. Breathing causes NTC to change resistance which leads to voltage changes on divider. ATmega328 in Arduino reads voltage with ADC and passes data to LabView function. Function...
Details, details ,details..... It's alive. (The electronics/coding is actually the easy part...) The real challenge is those semi-translucent tubes... Found some cheap transparent tubes at Home Depot used for storing flourescent light-bulbs. 1 1/2 "...
A dedicated phone line is a staple for any presidents desk. And now that Google is giving away phone numbers anyone can have a single use line for free. Using a TI Launchpad to interact with it is just fun.
I needed to remove the dials and the switch from the board because I wanted to have them accessible from the rim of the ear muff. However, each of these components had a minimum of 5 pins. My approach was to use a hot air gun to melt all the solder on...
