Logisim -Simulate Digital Logic Circuits

Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits.

With the capacity to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be used (and is used) to design and simulate entire CPUs for educational purposes.

Some Features
  • The wiring tool draws horizontal and vertical wires, automatically connecting to components and to other wires. It's very easy to draw circuits!
  • Circuit layouts can be used as "subcircuits" of other circuits, allowing for hierarchical circuit design.
  • Included circuit components include inputs and outputs, gates, multiplexers, arithmetic circuits, flip-flops, and RAM memory.
  • The included "combinational analysis" module allows for conversion between circuits, truth tables, and Boolean expressions.

Tuxgraphics AVR Microcontroller

You will find tutorials on how to build your own avr programmer, a digital DC power supply, a tiny web server, an ethernet weather station, usb slide show presenter and lots more.

Tuxgraphics AVR Microcontroller

digital DC power supply unit - A very small an really good DC bench power supply unit for your hobby lab. It has lots of features which you normally find only in very expensive power supplies. This one is affordable, small and easy to build.

Temperature and humidity measurements with the AVR web-server - Just add this one SHT11 sensor. No other components are needed to measure temperature + humitidy + dew point.

Mini 3 digit display, a small and inexpensive voltmeter module - We build a simple and inexpensive three digit display. It's a voltmeter module but it has also gerneral purpose digital IO pins.
