(...) This applies to the red 2x2 micromotor, not to the mini or power motor found in the RIS. I vaguely remember (try searching in LUGNET news) that the way to save a power motor, if at all possible, is to apply power in the right way, and not to (...)

According to a book by Ferrari brothers ("Building Robots With Lego Mindstorms") here's what you can try: --- How to release a Jammed Micromotor A micromotor jams so easily, you should know what to do when it occurs. The following list should help: (...) (23 years ago, 18-Mar-02, to lugnet.robotics.rcx.legos)

just give Lego a call at 1-800-363-2140 they'll have the new stuff in the mail the next day. you don't need to send in the broken parts either ...although for the sake of all Lego enthusiasts please don't take advantage of that. good luck "Jeremy (...)

Thanks for the follow-ups. Well, he's still a "friend" - after all he did give me the stuff for free and with no guarantees that it would work. I guess it'll just be a chance to crack open one of these babies! I think the stuff is pretty old, and (...) (23 years ago, 17-Mar-02, to lugnet.robotics.rcx.legos)

You may also be able to return them to Lego for free and get replacements, it depends on how old they are. I would try before you have to buy a new motor, they aren't the cheapest. Andy ----- Original Message ----- From: "Benton Jackson" (...) (23 years ago, 17-Mar-02, to lugnet.robotics.rcx.legos)

Jeremy, The motors that come with Mindstorms are geared internally, and it's probably jammed gears that are causing you woes. Your "friend" gave you some broken motors. I've never taken one apart-- it snaps together in a way that looks easy to break (...) (23 years ago, 17-Mar-02, to lugnet.robotics.rcx.legos)

I recently inherited an RCX 1.0, a serial IR tower and a few motors from a gracious friend. After many headaches, I finally got legOS 0.2.5 running on RH 7.1 and am able to compile and DL programs to the RCX. There is one odd thing, however - of the (...)

(...) this must be char test4 = 'a'; I think. Otherwise, you won't sent an 'a' anyway. But I can't imaginge why you want to do this. Michael Ash has shown a way to fiddle the strings into a contigous data area ready to be sent. But why do you want (...) (23 years ago, 15-Mar-02, to lugnet.robotics.rcx.legos)

(...) That's wrong. You should write "char test4 = 'a';", otherwise you are implicitly casting the character 'a' to a pointer to store it in test4 (the compiler should warn you about this; use -Wall to catch these errors).

This is really more of a general C question than an lnpd question. Anyway, the problem is with serialization; you want to take a structure in memory, and turn it into a stream of bytes, either to store in a file, send over a network, or whatever. (...)
