We needed a power meter for monitoring power consumption of our ham radio’s when in emergency communications mode (no grid). Although you can get these commercially, from the fully featured off grid power system capable Bogart Trimetric, to the single
We just received a bunch of MQ Series Gas Sensors. These inexpensive sensors include: MQ2 – Flammable Gas & Smoke MQ3 – Alcohol MQ4 – Methane MQ5 – LPG / Natural Gas MQ6 – LPG / IsoButane / Propane MQ7 –
I’ve previously posted about our micrometer to VGA project, and wanted to post an updated picture of that finished project in production. It’s a gear mic’ing station that takes 3 samples of a gear, rejects the gear if the samples
I’ve talked about this before, but since I just built another one last week, I thought I’d reshare this project, as it has a slight twist. The idea is to select the temperature you want with a potentiometer, and display
For Students & Educators Draw and print beautiful schematics for lab reports. In-browser simulations make it easy to quickly learn electronics concepts via just-for-fun playing and guided exploration. Our tools complement undergraduate and graduate electrical engineering classes, as well as
I recently received two HXT900 servos to play with. I used the sample servo code included in the Arduino IDE, that allows me to control the servo position with a potentiometer. The pot is connected to the arduino, with the
