Think you miss-heard. The RFID chip is NOT from an animal kit. Just the needle - it still comes sterilised and packed like a human one but is allot cheaper. They also have an RFID chip in them that must be removed first.Infection would seem to be the lesser concern...what about developing an allergic reaction/rejection of the foreign material? You said the device was rated for animal use....well that's not good enough for Human Beings....we tend to live for decades compared to lab mice/pets. Can screw up your immune system and lead to arthritis/Lupus Etc. This is a known problem for anything placed in the body. I guess the NHS will be there if & when you need it!
The thread Mr*Beaver pointed me to was on the 600RR forum for the main RFID controller. I would post the actual link, but don't know if I am allowed to link to other forums on here. Anyway I think it predates yours but that does not matter, since as you say the basic thing is in the public domain.Note that I first did this almost 6 yrs ago - and my innovation of the feedback diode creating the latch controlled by the Kill/Run switch is the simple mechanism that created an effective system without requirement for additional switch.
(Previous public domain versions utilizing this controller had used a dual-pole relay to create the latch but required additional switches to enable and drop)
I'm sorry but I don't see how they were. Both of us may have had the same thought of using the diodes, I don't know, but I'm not making any claims of ownership over any ideas - the 4013 latch is obviously public domain, since the flip flop is a basic building block in electronics and there are only a few ways that it can be configured. Claiming ownership of the idea of using a diode in a circuit is akin to claiming to have invented the wheel.I also advised of the blocking diode on the output of the RFID box to protect the circuit.
Both of these uncredited simple yet important features were developed by me.
I will take that as a compliment, thank you, although as long as schematics achieve their intended result it doesn't matter what they look like. I just use TinyCad for the schematics and Paint.NET for the visual aids (both free software) because I find them to be the quickest and most convenient. I wish that TinyCad would produce two colour wiring though.But then my schematic was not so pretty ...........
Indeed. I think that Beaver is the only one here who can legitimately lay claim to anything.
Yes diodes are simple - and everything is obvious when it has been done before.... I don't believe that anyone could claim credit for the use of diodes since they were the obvious answer to the problem. ....
nah, I've flown a few times since doing it. It's too small for most metal detectors and the wrong frequency for shops etcWill the RFID chip fail the scanners at airports....... and a million and one other concerns !!!!
Some people would give their right hand for that feature, by the way .....
