Please vote for this in the fitness challenge instead of a Fitbit or a smartwatch, you can build an Arduino powered fitness tracker for only $15! It tracks the pumping motion of your arms while running and uses an accelerometer to detect this. It is powered by an Arduino Nano and displays the unit that […]

At the fpv-community.de Forum I read about a DIY Weller station designed by Martin Kumm. Basically an Arduino shield to drive a Weller soldering tip. As there is not much to it, the board simply contains an precision OpAmp, a power MOSFET, 2 buttons for adjusting the temperature and a display to show the current
The DIY soldering robot which we have been building in our spare time over the past few months is now working and we have been able to solder some test Raspberry Pi expansion board headers with the machine. Before starting on this robot we looked at the various commercial soldering systems that are available. Wave

The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate. Here is a short list of features: – power: 9-28V, AC or DC – 2 separate heater control channels –
