I recently read a post from someone wanting to generate friendy sounds similar to R2D2 using an RCX. I thought this was a good challenge so set out to try. I was getting to the point where I could generate a number of similar friendly sounds and (...) (19 years ago, 21-Jun-05, to lugnet.robotics)

(...) Picture was missing. Though, as I understand the sound-generation, I doubt that actually you are able to produce an RCX hardware-laryngitis through a program that is based on the standard RCX firmware, because you just don't touch the hardware (...)

(...) Here is the sound driver section: (URL) Bellis, if you read this you can add this schematics to your RCX circuit collection to get everything together) It seems impossible that you have fried anything if you still get on/off sound: there is (...) (19 years ago, 22-Jun-05, to lugnet.robotics)

(...) Your circuit diagram checks out Philo, though a 47k resistor to ground should be added to the processor connection. As soon as I get access to Visio again, I'll write it up and post it with a credit. I was wondering what the other NAND gate is (...) (19 years ago, 25-Jun-05, to lugnet.robotics)

The note duration must be a compile time constant. By any chance were you trying to use a run-time variable (Robolab container) for this? This could explain your problem. -----Original Message----- From: news-gateway@lugnet.com (...) (19 years ago, 29-Jun-05, to lugnet.robotics)

(...) Hi Dick. No the frequency and loop number are managed by containers, but the note duration was set by using a control (or directly specified) in the version that caused the problem. (19 years ago, 29-Jun-05, to lugnet.robotics)
