Overview
Most ultrasonic distance sensors aren't waterproof which can be a problem if you need your project to withstand the elements outdoors. No need to worry any more!
This is a waterproof & ultrasonic distance sensor with a waterproof sealed emitter, suitable for outdoor applications such as car reversing sensors, security alarms, industrial inspection, etc. What will you make?

If you want to upgrade your soldering setup without spending a lot of money, then be sure to check out Angelo Casimiro's DIY Hakko 907 station. This low-cost device features an Arduino Nano to read the iron temperature via an LM358 op-amp, and regulates power to the handle and tip under PWM control using an IRFZ44N MOSFET. A potentiometer is implemented as a variable temperature knob, with the actual and preset temperature displayed on a 16x2 LCD screen, while an LED indicates whether the heating element is active. Everything is encased in a nicely printed and painted enclosure, which forms a brilliant little station that one could be proud to use. Full build instructions can be found here, including the PCB, code, and print files.
