So I thought that why not make a few, not everyone likes to solder or everyone is not that interested in touching Arduino. Or they are just lazy, what do I know :)
As we know there is a few wires in there, that makes it somehow hard to make a small series of sensors with equal size. So I designed a small PCB to come between RFID- and Arduino-boards. They just arrived so I had to put one quickly together and test it, I have to be learning something since the sensors worked right away…
The sensor I made for myself with wires was about 8,8mm thick, with this small PCB in between thickness is around 8.6mm so I actually gained a little which was a positive news
I also planned a bit ahead, the 2.4kΩ resistor in today’s prototype is a normal sized but in the final product will be replaced with SMD-model for cleaner overall look. I have solder pads for that ready in PCB.
The wire to receiver is ~30cm long and is soldered to middle-pcb, not to Arduino. This makes it more durable since there are no sharp turns in it.
When and how much?
Sometime. Waiting for SMD-resistors and shrink-wrap. I also think I need some cute stickers for it.. The price is still a small question, but excpect a lot more than DIY-version. I have to pay all the taxes etc, packing etc is not free and I have to get something for my work too.
