I've just discovered the 555

 After buying  20 x 555 for £1:50p uk I have discovered how much I like this very useful chip, so much so I've ordered another 40 just to keep me going you know ;)

Hi Sean  I just never realised you can do so much with them, I've made a ramp, and a square wave gen 1 Hz to 100Khz, just wondering if I can connect func & ramp together, also I made 1 Hz gen that pulse every second, looking at a one shot now  which will come in useful on the scope as mine doesn't have that. lovely chip.  a radio hams friend.

Connect the ramp to the control voltage of the square wave generator. Then the output will be a sweep.
