 | | What kind of plastic?
|
|
Hello, Lego is ABS plastic; MEK (Methyl-Ethyl Ketone) is good for glueing it. You might want to search through the lugnet.robotics archive, as there was an extensive thread on this last year. Hope this helps, Simon (...) (24 years ago, 11-Feb-01, to lugnet.robotics)

You may just have to send out grabage that the RCX and Scout are programmed not to recognize and deal with, or make your own "tower" that just has infrared transistors on the end of it. This is a major problem for many things, and no way has been (...) (24 years ago, 11-Feb-01, to lugnet.robotics)

WOW!! That is an amazing piece of work. Have you figured out if there is a way to do it with a Technic 9V battery box, such as the one included in the Technic Space Shuttle?

I'm trying to drive the IR tower from a C program running on a Linux PC. I find that the IR receiver only operates when the green light is on - and that only seems to go for a split second after I send characters to the tower from the PC. The (...) (24 years ago, 11-Feb-01, to lugnet.robotics)

| | Re: Is an RCX Output Amplfier, possible ?
|
|
You can run about 2 motors off of one output (as the RCX goes into thermal shutdown at 500ma and each motor will (on average) draw 200ma at a stall). Sorry I can't help you with the device part, but (don't let this start flames) can't you just hook (...) (24 years ago, 9-Feb-01, to lugnet.robotics)

Without a tank, there'd probably be a noticable effect, depending on how long your lines are. I've found the Lego ones are (...) (24 years ago, 10-Feb-01, to lugnet.technic, lugnet.robotics)

That little walker is quite an elegant solution. So few parts, so simple. My version users another motor as a counter balance (replace the "eye" with a geared moter). If I had more cams, I'd make this into a "caterpillar". Altavista's babelfish (...) (24 years ago, 10-Feb-01, to lugnet.robotics)
