Spring and summer usually means yard work and drudgery, and this year was no different. I went to my garden shed to get my trusty rubber boots and found that one of them (just one) had cracked to pieces. I thought it was odd that one would appear to kind of, well, “dry out” and [...]
I had a chance to review the 13.56MHz RFID field detector from Montie Gear and I have to say, I like this detector. It’s very thin, somewhat flexible, and is the size of a credit card so it fits in my wallet.

I love the internet. Thank jebuz I’m alive during such an amazing time… truly the dawn of a new age. I’ve been working on an amazing product development project with some fine chaps in the Amsterdam area… and the amazing thing is, we’ve never met in person. I know this is commonplace these days, but [...]
I recently had an issue with https functionality in WordPress when working behind a reverse proxy like Pound or nginx. I’m running Pound, so the solution for me was to add specific proto headers to the pound.cfg file; ## HTTPS listening ports ListenHTTPS HeadRemove "HTTP_X_FORWARDED_PROTO" HeadRemove "X_FORWARDED_PROTO" AddHeader "HTTP_X_FORWARDED_PROTO: https" AddHeader "X_FORWARDED_PROTO: https" ## HTTP [...]
I recently had a package show up in yum as being installed, but it was not or had been manually removed, so the yum removal process was broken and the ghost package was causing a yum update to fail. The solution was to use rpm to simply and safely remove the entry from the database, [...]
In this video I unlock a Samsung Ezon SHS-3120 electronic deadbolt using my NFC implant from http://dangerousthings.com Great things about the Ezon SHS-3120; – It’s completely self contained and battery powered – It uses only the UID bits of Mifare S50 tags for access control – It leaves memory contents of the S50 free for [...]
Combing through spec documents can be a pain in the ass. I recently had to come to a much better understanding of how security features worked inside Mifare S50 and S70 RFID tags, so I put this doc together to try to make the whole thing a little more understandable and easier to read. The [...]
This video demonstrates how to get a good consistent read with a 2x12mm Mifare S50 tag and a mobile phone. I use my Samsung Galaxy Nexus to read a glass 2x12mm S50 tag in a sterilization pouch, and read the tag implanted in my right hand.
I had some questions from Dangerous Things customers that centered around getting a good consistent read of the 2x12mm NFC compatible tags they purchased. Rather than respond via email, I figured it would be easier to make this video to explain how to get the tag to read consistently when used with typical “flat plane” [...]
