The PeakTech 5620 is a professional thermal imaging camera with a high thermal resolution of 384x288 thermal image points and a variety of excellent features for work in building thermography or industrial use.
In addition to the pure thermal image display, this new development also offers a PIP (picture-in-picture) display, a real image camera or a fusion function in which the contours of the real image recording are combined with the thermal image in order to ensure an even better display.
All of the image modes mentioned can also be used for video recording, which also enables audio recordings for the respective video.
The many functions are controlled via push buttons on the device, but also via the touch screen function of the color TFT display.
All thermal images can be opened and evaluated using the enclosed software, with subsequent changes, e.g. can be done on the pallet selection.

The Elektor Super Servo Tester can control servos and measure servo signals. It can test up to four servo channels at the same time.
The Super Servo Tester comes as a kit. All the parts required to assemble the Super Servo Tester are included in the kit. Assembling the kit requires basic soldering skills. The microcontroller is already programmed.
The Super Servo Tester features two operating modes: Control/Manual and Measure/Inputs.
In Control/Manual mode the Super Servo Tester generates control signals on its outputs for up to four servos or for the flight controller or ESC. The signals are controlled by the four potentiometers.
In Measure/Inputs the Super Servo Tester measures the servo signals connected to its inputs. These signals may come from for instance an ESC, a flight controller, or the receiver or another device. The signals are also routed to the outputs to control the servos or the flight controller or ESC. The results are shown on the display.
