It's here. My long anticipated Big Track, the toy I always wanted arrived today.

Looks pretty good too. Little dirty. Ripped it completely apart, scrubbed it with soapy water and a paint brush then hosed it off in the shower.

These things have about the absolute lowest quality circuit boards imaginable. Just unbelieveable. There are several places where the component legs caught the traces and peeled them away from the board itself.. then the whole mess was washed over with a wave of solder. It works though! Which is a suprise because it's supposed to be broken. I wiggled components, cleaned the contacts and it fired right up! Maybe I jostled something while taking it apart, but it works. At least for now.

Hey, there's a little optical shaft encoder in there! (And room for another, but the gearbox is moulded over it. Last minute design change maybe?)

I like this allot. It's bigger, zero turning radius and it adds interest. I think it's going to take the truck's place as platform for my sensor/battery experiments.

(My dog hates it.. absolutely loathes it.)

Oh my.. someone is sending me a "Big Trak"

The Big Trak was one of those ultra-cool toys back in about the early eighties. It was a programmable (via keypad) severely styled truck/tank looking thing that stored so many instructions and then carried them out on demand. I never owned one, but like every other kid at the time I absolutely drooled over them. I loved these things, they almost make the awful disco music and "big hair" of the eighties forgivable.

In the pictures I have found it looks pretty big, it may even be a better platform that the 4wd truck because of the turning radius (center axle differential steering) and just the larger size in general.

Of course it had to be broken :(

(some type of problem with the electronics, the rest of it is supposed to be in good shape. So at least I won't have any guilt pangs about opening it up.)
