The Logidules

The Logidules are small plastic boxes which snap together, establishing simultaneously the power connections. They have in addition 4 logical signals per side (8 for a double-size box) which greatly reduce the wiring of bussed interfaces.

The great advantage of logidules over Augat-like boards or over the racks found in many universities is that a logic symbol is visible; students are only required to handle essential wires (power supply and buses are connected automatically). The layout can grow at random in two directions and both contacts and wiring are reliable, due to the high quality connectors.

On the left, you see our latest logidule, which include a PIC microcontroller.

A simulator is available now, thanks to Pascal Comminot. It allows to play with gates, flip-flops, counters, PAL, EPROM and display timing diagrams.

Logidules have mostly been produced at the EPFL. Students following the Interface or Microprocessor lab are given a box which includes 82 Logidules from simple gates to microprocessors.

Logidules are also used by the LSL, where Prof Mange has developed complex Biodules.

The Logidules are also most valuable when developing the hardware of complex research projects. Parts of design can be tested, and different solutions can be experimented. The test of final systems is frequently simplified by signal generators or spys built with Logidules.
