 | | OT: some fun
|
| One night when his charge was pretty high, Micro-Farad decided to seek out a cute little coil to let him discharge. He picked up Milli-Amp and took her for a ride on his Megacycle. They rode across the Wheatstone bridge, around the sine waves, and (...) (23 years ago, 26-Apr-01, to lugnet.robotics)

| | Re: R: MIDI and WAV on the RCX
|
| Hi Guido, (...) That's good. (...) Why is that, you've know the complete structure (which I heard can be very different) of a wav file and decode it yourself, or am I missing something ? (...) That's great intention ! and too difficult for me. (...) (...) (23 years ago, 4-May-01, to lugnet.robotics)

| | IR at RTL9
|
| Hi everyone, I have a few questions about IR. It seems that we are going to be seeing a lot of multiple RCX robots at the next event. This is great, but I was really wanting to do proximity detection (which requires IR). Since the other robot(s) (...) (23 years ago, 2-May-01, to lugnet.org.ca.rtltoronto)

| | Ir and proximity detection
|
| Hi everyone, We in Toronto are going to be having another robotics competition soon. Our new rules allow for multiple Rcx robots. This means that they will have to send IR signals back and forth to communicate. Unfortunately, I was really wanting to (...) (23 years ago, 2-May-01, to lugnet.robotics)

| | generating waves
|
| Hi from Germany, I need some help for generating a sqare wave with the Handyboard. The frequency should be 16kHz at least. And the number of peeks must be countable. I only could made a 1kHz symmetrical square wave with low=high=0,5ms. For that I (...) (23 years ago, 10-May-01, to lugnet.robotics.handyboard)

| In lugnet.robotics.handyboard, Matthias Weber writes: I think your best bet would be to create an external oscillator that could be controlled using one of the TOC's. I mention the TOC's in case you need to pulse the oscillation (infrared remote (...) (23 years ago, 17-May-01, to lugnet.robotics.handyboard)

| (...) Ummm, that doesn't make sense. You know where the midpoint is by knowing the baud rate, and hence the bit width. The only time you need to sample at the beginning of the bit time is to look for a start bit. This is all very basic asynchronous (...) (23 years ago, 29-May-01, to lugnet.robotics)

| (...) Actually, it's the computer itself that determines the duty cycle. This does mean that you could change the duty cycle, but you should be aware that it would be at the expense of noise immunity and would require a higher sampling rate from the (...)
