content: Quote from: EEVblog on November 24, 2015, 12:34:50 amThe Military Mystery Item is a missile pulse duration modulation encoder for wireless data transmission, possibly for intercontinental ballistic missiles. See one of the engineers who worked at on it "ELLIS G. GOODWIN"https://radiwiki.wikispaces.com/file/view/resumesA-H.pdf- search "goodwin" in PDF:Quote"Asset" missile is unnamed, however I think this module may have also been used in NASAs Project FIREhttp://www.wired.com/2012/07/interplanetary-reentry-tests-1966/because project documents state a 90 x 10 PDM communication systemhttp://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19660029120.pdf,http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19650004794.pdf,http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19790076764.pdf, the dates seem to be right, and project FIRE used an asset missile platform. The missile turns out to be an intercontinental ballistic missile, from theAtlas D ICBMfamily. These were used for the early orbital space program (1960's) and some military intelligence stuff.Edit - This is definitely early space program related, Contract No on side nas9 is a nasa contract. Project FIRE was at the Lyndon B. Johnson Space Center, housing the Manned Spacecraft Center. (MSC) The Module spec says MSC on the side. Also the serial number of #025 makes sense now, and so does the construction

content: Love the USA Today paper. Sadly I missed out on the sale directly from USA today but managed to pick one up fairly cheap on eBay. Seems like the seller didn't really see the value or significance (clearly wasn't a BTTF fan).

content: The postcard from \tezz at 22:24 mentions that he is working on a project using an instrument cluster from an E46 BMW. It has a couple of links in the text on the postcard. If you go to his blog athttp://tsharp.me.uk/, you can see he is working on decoding the CAN bus signals so he can get his BMW instrument cluster working in a car racing simulator he is building. This was interesting to me because I have an extra instrument cluster from an E32 or E34 BMW (both of those body series used the same instrument cluster and wiring), as well as another one that is still installed in the whole car. Mine is an earlier model car, but it also used the CAN bus, and probably uses a very similar protocol.

content: Quote from: Clear as mud on November 24, 2015, 01:44:14 pmTezz HereEntirely possible, some of the base information I used to get an understanding of this cluster came from documents for other BMWs, particulary the E36 series. Some of this cluster's functionality is spread onto a linbus-style interface called "K-Bus"/"I-Bus" which is actually quite well documented:http://web.comhem.se/mulle2/IBUSInsideDRAFTREV5.pdfThe hardest part there was finding what was useful to my project.Learnt heaps about BMWs, various bus types, used my Hitachi Analogue 'scope for the first time, destroyed components and had fun in the processI've not had much time to put into the project as I'm currently finishing my last year of University however I do want to round off the documentation and the host software when i get the chance. As it stands it works in Euro Truck Simulator 2 quite well. Happy to answer any questions but I am by no means an electronics expert!Made my day seeing my postcard

content: I think that despite the inevitable deluge of damning evidence, many people will stick to their guns, and swear by the batteriser. Just like audiophools. They will just come up with abstract, immeasurable phrases like, "the batteriser gives my batteries more perkiness and liveliness." and "My batteries have morezest".That's probably what the creators are banking on too.Just wait.

content: Uhm, it looks someone received another free postcard from me, to be sincere it was hard to believe that it would have crossed the whole globe without letting anyone noticing about the trick, but it did, "Beauty" hehehe. So sorry that's actually the best I can send to you, i'll find a way to send bigger parcels without having to sell my kidneys, that's a promise!Luca
