An Ohmmeter device using Raspberry PI 2B with ADS1015 as ADC   https://github.com/Sherbieny/Ohmmeter-Pi http://fritzing.org/projects/pi-ohmmeter Setup Items needed: PC or Laptop Raspberry Pi (I used model 2B) ADS1015 12bit ADC converter (if you use 1115 which is 16bit, there will be slight changes) Breadbord, wires, resistors Adafruit assembled Pi T-Cobbler Plus - GPIO Breakout (Optional) Circuit setup Refer to fritzing diagrams in schematics folder Configuration SSH, VNC or anyot ...
I started this post as a Wifi Analyzer... but the more I got into it the more it became a complete handheld network analyzer for wireless as well as wired for performing basic network functions such as speed tests and pings, on up to measuring signal strength and identifying noise.   Here are the requirements:   Small form factor (hand held) not much larger than your palm (5 in. screen range), I'm thinking a strap across the back side of your hand 4 hour minimum rechargeable battery ...
Hi i resently got an idea after learning about freenas interface web based I learned that freenas lets you to turn off your computer form the web so i was thinking is it possible to turn the comouter on by the web interface so i tryed to solve this problum. and i was woundering is it possible to have the raspberry turn on my computer by web interface system useing the pins that it had i am well ware of that i could not do this by raspberry ip and a computer i would need a modual to try this out ...
in the office building I work we have DIY addressable led strips surrounding every floor of the building to make it glow at night. It's a part of my job to maintain this setup and unfortunately the setup breaks down a lot.   We we got a defect then I have to open up the sealing and get the 3m long led bar out and take it to the warehouse to test the led strip. I have already bought a wireless soldering iron so I can do small repairs without taking the led strip out of the sealing, but I sti ...
How about building a Raspberry Pi universal multimeter and oscilloscope. You could use the bitscope mod and if you can create a application you can make a multimeter app to measure voltage, resistance and current (Or even a LCR function) ...
This is my submission to the Element14 Project14 DIY   The problem I have recently been doing extensive experimentation with recycled batteries as well as voltage regulators and line control circuits. The customary approach requires a programmable DC load to the connected such that the output can be tested under various conditions. Unfortunately, these commercial solutions are quite expensive in addition to being big and bulky. Due to a constant fear of the spouse with regards to unexplain ...
