Hello to all!!
@Seth: Thanks so much for creating such a great pdf, great work!
And very organized, I will be giving you some info on some components later on, like the NTE576 is cross referenced to the UF505 which is a more "international" number...Thanks!
@John Stone: Great work there !!, And agree 200% that Opto-Isolators is the only way to go to handle higher V on future circuits, yours looks excellent!!
Yes I do have a working P-N Channel oscillator, I have described here many times, it is based on same 555 timer original, and I just extended a second 555 (IC2) as an inverted signal (mirror), I used same exact power feeding from first IC1, and adjustments are done by "Master" IC1, I just attached Leg 3 from IC1 (Still going to N-Channels 100 Ohms-330 TO Gates of N-Channels) but connected to Leg 2 (trigger) of IC2, then IC2 drive the P-Channel Fet's, same 100-330 ohms, EXCEPT Gate Bias goes to POSITIVE by a 4.7 K resistor on each P-Fet. I will supply a diag soon, but I posted before where I got it from...but now am working still on Motors...and Asymm.
My recommendation to starters: Please try first the plain "Jame" 555 cheaper ways with N-Channels, and actually be very honest here, the P-Fet's are NOT as strong to drive High Impact Coils, and as a matter of fact, I have Not been able to find a perfect match for the NTE2397...and the "Ideal Oscillator of this types should be a "Factory almost identical Spec's but as different transistors (something similar to Audio Amps Matches, so you guys have an idea)...This brings some problems at low frequencies pulsing, they do not pulse exactly equally...P-Fet's take longer to reach synchrony to N-Channels, but what happens is they start at zero resistance til they start increasing resistance to Mega-ohms between Source-Gate...I really do not have the time right now to fix that issue, maybe biasing gates more idk...but it works ok so far, and for heavy motor pulse (and so I recommend on very low resistance Coils, N-Channels, strong Fet's)... I use the N-Channels.
Now get ready for what is "Coming soon to a Theater near you...", Hold Your Panties and Socks real tight...
Regards and Good bye to all.
@ZPE: Great and impressive Neon lighting there!! WOW!!...You are "Full Blasting it!!
@Bob French: Great and patient work with the CF Bob!! Congratulations!!excellent results,
@Bob and ZPE: The LADY is "captivating" isn't SHE?
Prochiro: great work, just like your friend Bob!! excellent!
@Larry: Get ready to build and install an "Endless Running Time Motor" on your R/C Planes...I highly recommend to install one of those "Air Range Alarm" circuits so you don't loose it in case a returning servo Aileron will malfunction...
Regards to all, and I'll see you all on the 4th...
