DB9 connectors (serial port)

To build the PC interface you need the female connector (see photo on the left).
Warning: the male connector pin-numbering scheme is opposed to the female one (see right). This characteristic allows a consistent numbering after male and female connectors plug together. Try it to believe!
Tip: look at the connector through a magnifyng glass: most manufacturers print tiny pin-numbers on the connector's body.

Microswitch

Microswitches are small switches with both normally open and normally closed contacts. The switch is driven by a metallic lever.
Its three pins are usually marked as: COM (common), NC (opens on make), NO (closes on make).
You can find them in electrical parts stores and, much cheaper, as surplus parts in Ham fairs and flea markets.

Alternative infrared receivers

The best module is the TSOP1836, but if you are unable to get one here are some alternatives. The IS1U60 (Sharp), SFH506 (Sharp), TSOP1736 (Telefunken) work well with the Nutchip. The TSOP1838 works within a shorter range (it is designed for a carrier frequency of 38 kHz, very close to the optimal 36 kHz required by Nutchips). Any other module desiged for a carrier frequency of about 36 kHz will work, altough with sub-optimal range. A 38 kHz module is OK, a 40 kHz one could be acceptable in some occasions, but a 100 kHz module will not work at all.

Power relay for small appliances


A Merlin Gerin relay, suitable for DIN rail mounting.
If the relay coil voltage differs from mains voltage, you must insert a transformer to adapt its value.

Appliances requiring high power (more than 2 amperes, or 400W for 230V mains rating) need a power relay to be switched on and off.

The power relay is NOT driven directly from the Nutchip: instead, a small relay (the driver relay) is used to energize the coil of the power relay. Therefore the Nutchips energizes the driver relay, which in turn energizes the power relay, which in turn switches your appliance on (or off).
Do not connect power relays by yourself, it is dangerous! Have an expert technician do it for you.


How to drive a 220V power relay with a smaller relay (driver relay). The driver relay contact must be rated for 250V operation. Pin numbering refers to a Merlin Gerin relay.
