Any chance on doing a RFID Analyser type product? Like the Proxmark3? I am interested in the low frequency 125kHz RFID systems.
Ideally the product should be able to read, emulate, write any type of tag (various frequencies and modulations) or NFC device . Additionally a sniff mode where the communication with a tag/device and another reader/device can be monitored for debugging.
I would of bought a proxmark 3 but the cost is quite high, and the development seems to have stalled. Plus the documentation and compiled releases could be better.
[quote author="codefinger"] I contacted rsdio privately, but his Mac program only captures and displays the data. As far as I can tell now, no one has used the USB IR Toy to actually transmit the captured codes from their PC to control a device. [/quote]I have not been successful yet either. I have just given up for the time being.
[quote author="ian"] * Selectable duty cycle. (NEC protocol has a duty cycle of 25% to 33%) * Some way to measure the carrier frequency. Will need to add a photodiode or something. [/quote]For that matter, someway to measure the duty cycle as well.
Thanks Ian, I noticed the post on your blog and it immediately clicked. Just as well I went away this Easter holiday weekend otherwise I would of spent considerable time trying to figure it out. I think you might be correct with the self test passing as I checked the IR LED was transmitting with a mobile phone camera. The IR LED is a little on the dim side but I did not pay any attention to that thinking it is due to the less than average camera. I should of compared it against the IR remotes.
Anyway, these things happen. Hence the box of dud prototype boards most prototypers have. Thanks for the offer to repair but it is only 2 minutes with a soldering iron, hardly worth the effort shipping it half way around the world twice (I'm in Australia).
I'll post back with results on the weekend when I give this another go.
I can't seem to get any of my AV equipment to respond to USB IR Toy. I am using IRIO mode to capture the IR signal from the IR remote. Then trying to retransmit it from the IR Toy to the AV equipment. I have set the IR toy to 8 bit mode to match the incoming signal. The yellow LED to lights to indicate reception and transmission. I have tried it with my TV, Logitech Z5500 speakers and my Yamaha Amp.
I wondering if the carrier frequency does not match or the sampling resolution is not high enough or the modulation is not quite right.
