The 555 timer

Hello gang,
It has been said some people shy away from Flowstone because it has no electronic components like resistors, capacitors, diodes, transistors, and so on. Also a few even asked why no 555 timer. Well one solution I have always used and like is creating your own stuff. Thanks to Martin we have resistors and capacitors from his excellent “double-T-filter”, and now I have made a 555 timer. I call it the X555, because it is experimental. It works very close to the true hardware 555 timer, but not 100%. It does do timing functions (one shot). For instance set the “Mode Selector” to trigger, select a resistor value of 10, and a capacitor value of .1, and then press the trigger button till the led comes on and watch the scope. It will also oscillate. Set the mode selector to free running, select a resistor value of 10, and a capacitor value of .001, and view scope. Of course other values of resistors and capacitor values can be selected for other timings and oscillator frequencies. Now I only chose some common resistor and capacitor values to play with. The whole idea is for you to experiment with this yourself. Try other values till you find the upper and lower limits of it. There are also other configurations that can be had and many, many uses. If you do not know the 555 timer, search the internet. You will find a world of information and applications.
Ok then that’s it, enjoy. Please do experiment a lot and if you create any new configurations and make any great application, PLEASE post them. Also any other comments, bugs, suggestions, are always welcome.
P.S., Other electronic component stuff coming down the road, watch for them.
Later then, BobF…..
