| | Challenge: Technic Model of the Month!
|
|
FUT: lugnet.technic Hi all! I've decided the Technic genre needs a boost so I have made a Technic model of the month competition/challenge similar to ldraw.org's MOTM & SOTM. Each month a winner will be elected by an e-mail voting process. For more (...) (23 years ago, 14-Feb-02, to lugnet.technic, lugnet.announce, lugnet.build, lugnet.general, lugnet.robotics)

| | Re: Power to RCX

(...) Yes, but any regulator would convert power uselessly into heat, probably too much if you use a much higher voltage and draw some current. It would be better to use higher voltage motor controllers directly (if they exist). And of course this (...) (23 years ago, 14-Feb-02, to lugnet.robotics.rcx)

| | Re: Power to RCX

(...) Utter nonsense until you destroy the controller itself. Remember, while the Lego motors can take a fairly substantial voltage without being destroyed, the same is not true of the motor controller within the RCX. There is a voltage limit for (...)

hi Peter, Why did you remove the IR diodes ? I think it's not necessary, or am I missing something. It would even be nicer, if also the IR-sensor could be left in place, but I don't know the Lego circuit. Stef Mientki (...) (23 years ago, 13-Feb-02, to lugnet.robotics)

Nice idea Peter !! I'll add it to my collection about the IR port of the RCX. At first I didnt see what your design could mean foe me, but .... This could be an alternative way to add "intelligent" sensors (for example through PIC or some other (...) (23 years ago, 13-Feb-02, to lugnet.robotics)

(...) What I meant when i said "unregulated" was a power supply without a 78xx in it. The power supply that I am using consists of a transformer, rectifier (4 diodes) and a 4700uf cap. This means that while it does give a clean voltage, that voltage (...) (23 years ago, 13-Feb-02, to lugnet.robotics)
