hey all. recently i upgraded my RFID chip to a writable version of the same basic protocol type (close-range passive and if i remember right it's still an EM4102 chip.) it's one of the ones from Dangerous Things (Amaal Graafstra's shop), which i'd happily recommend - he was able to arrange fast shipping, the chip arrived very well protected, etc. i also managed to source a newer, sleeker USB tag reader, although its range is awful compared to my old Phidgets one so i might just carry on using the old one. i even got hold of some topical benzocaine cream which is a first. that stuff was extremely useful & i might have to try it the next time i do any fingertip installations, since a lot of the difficulty with those comes from the pain and the toughness of the fascia in that area - having the area numbed might well mean i can go a bit slower, be a bit more precise with the depth of the needle puncture incision.
i did the chip installation at home, with my standard bleach-and-alcohol treatment for the table i was using and hibiscrub to sterilise the hand alongside sealed tools and glove for the other one. i figured out a long time ago that it's better to use a needle than a scalpel, so in the pix i'm gonna share here you'll see me making the incision with a 4mm sterile piercer's needle blade. i did also acquire two of the weird pre-loaded needle syringes a vet would use to install an animal's ID chip, but those turned out to be difficult to unload (you can't use an animal ID chip on a person cause they're specialised things that hold animal-specific information, can't be overwritten with any other info, and require a specialist reader and software what is very expensive.)
so here's some pix:
the whole thing is very well healed now, had no healing problems whatsoever, changed dressing daily for a week and then it was pretty much done. the whole procedure was filmed too, by both Paul and some professionals, but i don't know what's happening with that footage so i can't release it to you yet or talk about what it's for. in all likelihood nothing will come of it and i can put Paul's video up here or on rutube for you after i get the go ahead, so watch this space or my twitter & i can let you know what goes down. i'm also currently working on something else, but no point posting about it until i know whether it's a viable experiment or not. if it fails spectacularly i'll post pix of that too just for the lulz.
