 | | Announcing BricxCC - formerly known as RcxCC

|
I'm excited to announce the availability of the latest release of my enhanced version of Mark Overmars' original RcxCC program. Due to a recent e-mail from the FairPlay folks at The LEGO Company, I have renamed the program Bricx Command Center or (...) (23 years ago, 10-Oct-01, to lugnet.robotics.rcx.nqc)

Hi all, It seems I missed this thread... (...) As suggested by Rainer, if you use an external battery everything is much simpler, you could even use a 4.5V battery to avoid regulator. (...) I don't think you can improve this circuit with a simple (...) (23 years ago, 10-Oct-01, to lugnet.robotics.rcx)

(...) Hi Gareth, maybe you don't need an external regulator ?!?! But, the specs also say that rating of supply voltage is "-0.3 to +7V". Do you know what happens to the sharp if supply voltage rises above +7V ??? (the mux has a supply voltage of +9V (...) (23 years ago, 9-Oct-01, to lugnet.robotics.rcx)

(...) Instead of using resistors, you can use RAW mode which measures how far in the sensor was pushed. Then use a bit of tape to prevent one of the sensors from being pushed in all the way. BTW, I am lucky enough to have a defective touch sensor (...) (23 years ago, 9-Oct-01, to lugnet.robotics.rcx.legos)

I'm thinking about calling RcxCC by the new name of BricxCC (pronounced BricksCC). I'm not particularly keen on it or any other name I've thought of or that anyone has mentioned to me. SdyCC? QbwCC? ArsyExCC? Now that one's not bad. :-) Thanks for (...) (23 years ago, 9-Oct-01, to lugnet.robotics.rcx)

FYI - I just noticed in the component specs from Sharp that the GP2D12 (and GP2D15 for that matter) have a built-in voltage regulator. See (URL) is an external regulator a necessary precaution? Just curious... - Gareth (23 years ago, 9-Oct-01, to lugnet.robotics.rcx)

In both cases I have to remove the batteries and wait for (...) (23 years ago, 8-Oct-01, to lugnet.robotics.rcx.legos)
