| Hi Daniel, (...) you can do more levels by something like the Bresenham algorithm, i.e. for speed 4.5 you turn it on for 4ms and 5ms of the 10ms alternatively. Though 10 levels should normally suffice, the standard LEGO train controller has fewer (...) (20 years ago, 9-Jul-04, to lugnet.robotics.rcx.java)

|
| (...) Sam, you need to tell us more about 'how much' light-tightness you want and if the ambient has some or no light at all. As an extreme example, in testing a photographic darkroom for light-tightness it is common to hang a few rolls of unexposed (...) (20 years ago, 9-Jul-04, to lugnet.robotics.rcx)

|
| (...) The simple answer is "maybe"! If you have one handy, try it. I'm not sure whether the RCX will cope with a capacitive load rather than an inductive one, so I would advise you not to put the capacitor across the RCX output without a motor in (...)

| | | | | Light Sensor question
|
| I'm new to mindstorms so I have a simple question. At work, we're trying to measure the light tightness of rings. Basically this involves observing how much light passes through the outside edge of a ring. Is there any way a mindstorm light sensor (...) (20 years ago, 8-Jul-04, to lugnet.robotics.rcx)

| (...) hi Juergen I tried it with load, and it works much better! Only that the speed is not very stable in the curves. (...) If i use a cycle of 10ms, then i could only use 10 different speeds, because the Thread.sleep has a resolution of 1ms... (...) (20 years ago, 8-Jul-04, to lugnet.robotics.rcx.java)

|
| (...) Hi Joe, Thank you for your fast reply, you are right, alle the 4 RCXs can see the tower, but I dont think thats the problem, since the problem also is present when only one RCX is turned on, or the other 3 are removed from the place. I only (...) (20 years ago, 7-Jul-04, to lugnet.robotics.rcx, FTX)

|
| From the picture (d1_p31) it looks as though all 4 RCXs can see the tower. I don't know anything about pcrcxcomm.jar or rcxf7port; and not much about lejos, however, if all 4 RCXs try to respond to the tower, you will have collisions. Try covering (...)

I have implementet some controlling and a lot of functions in the model, including a userinterface made in Java for a laptop. The crane is controlled by a (...)

| Hi, I'd like to know if the v1 of brickOS with the support of the usb tower for linux (without patch) is going to come soon or not. Actually I have tried many things but without success. Thank's Nil (20 years ago, 7-Jul-04, to lugnet.robotics.rcx.legos)
