I have simply set the 08M2 to produce a PWM signal at about a 50% duty cycle (PWMOut C.2, 249, 499) and am watching it on a scope. At random times the signal goes flat (0V) and then resumes the pwm. I have checked for loose wires and bad connections but it still does this randomly turning the...

I am working on a project in which I am using a picaxe but need some broader tips that some who visit here may be able to help with. I have a replaytv 5000 (one of the original dvr's) and am trying to coordinate it with a new directv satellite box. I need to have the replaytv change the channel...

I am trying to use a wall transformer that shows an output of 10V DC and want to regulate it down to 5V for a picaxe project. Using a 7805 regulator causes the 7805 to overheat because of the voltage difference and extra energy to be dissipated. So, in general, how does one solve the problem...

What am I forgetting? I am trying to use a 74LS04 to buffer a pulsout output from a picaxe 08M but I can't even get the 7407 to behave. Should I not get the same output as I put in to a 7407? I have all unused inputs tied high or low Thanks for any help. Dave
