HAM Constructions

You can find here constructions for radioamateurs. Receivers, transmitters, measuring and so on.

Power Supply Constructions

Robots

You can find here small robots. Some are made of MLAB modules, others are independent constructions.

Solar Cell Tester

Outdated construction. The tester measures Voltage/Current characteristics of battery of solar cells. The results can be sent to PC via RS232. It automatically finds the power optimum.

Dog finder - Track Logger

The track is logged in NMEA format on SD/MMC card.

Ionisation Radiation Logger

Logger is an application developed during the "Physics' Day" organised for secondary school students at the Faculty of Nuclear Sciences and Physical Engineering in Prague. It can log intensity of ionising radiation with GPS coordinates.

L C T Meter

LCT Meter is able to measure inductance L, capacitance C and temperature T. It can measure reliably from small values of L and C. It is based on PIC processor.

Melody Bell

Programmable melody bell is ale to hold up to 500 notes in up to 15 songs. The songs can be programmed via RS232. The construction is based on PIC processor.

Mrakomer (Claudsmeter)

Cloudsmeter is a robotics device for measurement the clouds coverage. This device is especially constructed for protection of robotics telescopes against rain and snow.

Mrakomer3 (Claudsmeter)

New design of the Cloudsmeter. This is a device for measurement the clouds coverage. This device is especially constructed for protection of robotics telescopes against rain and snow.

Mrakoměr4 (Claudsmeter)

This is a device for measurement the clouds coverage. This device is especially constructed for protection of robotics telescopes against rain and snow. This is a second generation without moving parts.

Timer for robotics

The timer measures time from start to finish. It is intended for optimisation of small robots (robotic cars). It can send time data to the PC via RS232 interface.

Small blinker for children with two LEDs

The blinker is constructed so that it resembles smiling human face. The construction is simple and even small child is able to make it. Tested. The blinker is low power device with long battery life.

Electric Fence

This device is a high voltage generator for an electric fence. This device was designed especially for goats and sheep.

Homemade GPS

If you don't like commercial GPS receivers, you can make your own to fit your needs and tastes. This project continues as a GPSnavigator project.
