Data logging constructions

There are some construction which collect measured data. i.e humidity, temperature radioactivity, light flux.

HAM Constructions

Receivers,transmitters and measuring for radioamateurs and radioastronomers.

Laboratory instruments

Instrument and devices for special experiments.

Measurement instruments

Instrument and devices for special measurement, short time intervals, light, laser ranging etc.

Power Supply Constructions

Solution for powering MLAB modules and construction from external power source.

Robots

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

Train Timer

The timer for Lego trains was designed to enable long-term reliable switching of power for several rails. The timer has 8 relay outputs which are able to switch on and off the power supply or to reverse polarity of that. The firmware has configurable times for all outputs with possibility of random times. The setup may be changed via USB interface.

Tools for assembly and testing

There are some constructions useful to assemply and test modules

Experimental electromagnetic gun

This experimental gun is intended to use for asteroid impact modeling.

PIC based DIY GPS

If you don't like commercial GPS receivers, you can make your own to fit your needs and tastes. You can get longer battery life, original design and so one.

LX200obfuscator

It is a device for connecting LX200 classic to a computer through USB and simulation of LX200 keyboard. It is useful if you have LX200 mount without keyboard.

Laser transmitter for miniature rangefinder

This thesis is aimed on investigation of use a diode pumped solid state frequency doubled laser module (with 532nm output wavelenght) as LASER transmitter for miniature laser range finder. This module is widely used in green laser pointers. For that reason it is easily available in oposition to semiconductor laser diodes for this wavelenghts.

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 (Clouds sensor)

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 (Clouds sensor)

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 (Clouds sensor)

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.

Quad stopwatch timer

The timer measures time from start to finish in four sectors. It can send time data to the PC via emulated RS232 interface at USB.

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.

Simple digital thermometer

This thermometer reads the temperature from DS18B20 sensor and displays it on LCD in Kelvin degrees.

Duckweed collecting air-boat (Žabincosběrač I)

A demonstrative construction of simple air-boat which is constructed from MLAB electronics modules. This boat can also be used for collecting a unwanted duckweed from some pond.

Home automation

Demonstrative design shows how use MLAB modules to intelligent home automation.

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.

AVR based DIY GPS

If you don't like commercial GPS receivers, you can make your own to fit your needs and tastes. You can get longer battery life, original design and so one.
