Pictured above is a custom sensor that I just finished making for someone. They wanted individual toggle switches, like those on our toggle array but not grouped together. They are going to be used with a Kroonde sensor interface, which is why they are fitted with a different cable (as seen with one of the switches above) than what we normally use.

I obviously have a conflict of interest in talking about the Kroonde, so I won’t say too much about it. One of the more annoying facets of it, however, does affect me. When building this order, I had to make the plugs on the end of the cable meet the pin order for the Kroonde – which is different than almost everyone else’s pin configuration. For example, when we made the Teabox we made sure that the pin layout was the same as the I-Cube. The Kroonde will take I-Cube style connections, but with the pins in a different order things will burn up if you plug some sensors! Ack!

• Pin 1: Ground
• Pin 2: Sensor
• Pin 3: 5V

• Pin 1: Ground
• Pin 2: 5V
• Pin 3: Sensor

So you can see that pins 2 and 3 are reversed.

Anyway, I rather like the single switches. Prior to being contacted with the request I hadn’t thought about making them. It turned out that we could cut down one of our existing circuit boards to do it, so it was really easy. Perhaps we’ll consider making it an official sensor someday…
