content: BTW, the "snow mobile" is a little version of "BigTrak" a very famous and now "cult" toy from the late 1970's '/ early 1980's!http://en.wikipedia.org/wiki/Big_TrakIt's actually pretty cleverly designed!http://www.robotroom.com/BigTrak.html

content: I bet the clear second "photodiode" on the back of the car sign is actually a LED that flashes when a signal from the remote is received. Without some feedback it would be hard to tell if the remote worked or was properly aimed.

content: I see someone already beat me to it, but that weird key-chain "snowmobile" is actually a miniature replica of a Milton Bradly BigTrak from 1978. The original BigTrak was a programmable tank. Probably one of the coolest electronic toys from the late 70's. I had so much fun as a child learning to program BigTrak . . . forward 10 - left 90 - forward 10, right 180, fire 3 times. It was a robotic toy that was way ahead of its time, and therefor went over most peoples heads. There was a UK company that made a run of fully functional replicas back in 2010. I have an original BigTrak in my retro electronics collection.

content: Aw man, TI Voyage - the greatest calculator ever made, to start off the flamewar...Seriously though, I still use mine almost every day...even without dedicated exponent button. Especially the built-in Basic interpreter combined with full QWERTY keyboard will allow you to automate menial tasks really quickly, like calculating voltage dividers and spitting out valid E-Series resistor values...Some guys even wrote a great little GCC extension that supports TIs kernel calls so you can use their CAS instructions like symbolic solving from your own little high-performance(compared to Basic) programs - awesome.Mate of mine built a portable radio telescope from a satellite dish and one of these for data acquisition back in 2004, before the age of smartphones - awesome.

content: Quote from: urbis on February 17, 2015, 08:50:18 amI was shocked too. Perhaps they didn't sell them in Australia?Quote from: urbis on February 17, 2015, 08:50:18 amGood idea. I couldn't part with my original BigTrak, but I would gladly donate a fully functional BigTrak Jr from 2010 if Dave expresses interest in doing a teardown. Probably not much to see inside. Sagan might get a kick out of it if Daddy helped with the programming.

content: I have been watching your YouTube Channel for a few months and I love it. Today, when I was watching your mailbag Tuesday I accidently pressed the CC icon. I must say, YouTube is way off. It was hilarious. Great Vlog though. Look forward to it every week.

content: Thanks Urbis, I had almost forgotten that bit of mail. I remember going to SAA and was given a tour, which included a walk through the restoration of the only flying Ju52 in Africa.http://en.wikipedia.org/wiki/Junkers_Ju_52http://en.wikipedia.org/wiki/South_African_Airways_Museum_SocietyA lot of the aircraft I worked on were older than me, and I know some of the original pilots who went and did the delivery of them.

They don't answer their email and the phone number is out of serviceI am hoping they will see this and chime in.Thanks,Dan Pattisonhttp://www.remotemonitoringsystems.ca/uF-nF-pF.php
