General Questions / Re: voltage regulator in place of clipping diode

One last addition. I'm using a discrete built regulator not lm317

I'm going to agree with Jon. I built the glass blower and its very nice. By far the most powerful boost. Be careful sub transistors. They do their magic.

When u said improper I meant that in other applications involving power.

General Questions / voltage regulator in place of clipping diode
« on: September 18, 2013, 09:35:55 AM »
HI everyone, it's been a while since I've posted as I have been venturing in to radio to learn more about proper electronics before learning how to properly mangle a sine wave.

During my studies and construction of 20 cb radios I've learned a lot about different types of voltage regulator. It reminded me of all the different ways I tried to diode clip.  Every pdf and page I read showed diode clipping as improper. I purposely tend to over engineer bc I learn more.

My question is if I use some type of variable regulator will it work in place of the typical diode clipping config. My intention is to try and and adjust the level of clipping in a unique way. 

Seems to me that unless there is something I'm misunderstanding about this it should work well. Any info or tips would be appreciated.

Agreed with others. It crap. I use bk precision/Tektronix can be found on ebay 50-150$. Just try and get probes with it. 9 out of 10 don't. You can make your own but they don't come out well

Where did you get that clad?

If it isn't grounding issue than its a mistake you made some where. Whip out you probes and trace the signal, maybe you got a pin out wrong or something

If you wanted a simple passive lpf it would be fairly simple to construct on the pot it self. You you wanted to go active it might be easier to design a daughter board or redesign the circuit. If your just trying to trim off some highs use the rc method and just construct on the pot terminals

If you were etching something large and complicated /delicate it might be worth it to tin. With small signal circuits with a couple of stages I don't see it very necessary. I've attempted to tin with solder and it just didn't work very well.. for me. However, like a previous poster said the liquid tin does work well and makes things neater.  One more thing to stroke the ocd complex lol

O dude.. im redneck engineer at best lol. I've taught myself every thing minus what others in these forums have shared.

Keep going though man, specially since you got that pt2 delay going. Back when I started messing with that it took me a while to get it working. Id say I gained a great life skill through all this. I'm a basic gadget fixer now. Very important in today age. Your on the right track. Don't be scared to try different parts using sockets and what not, that's where I started understanding why these guys use the value s they use.

As for the wire not fitting here's a tip. Get the tip of the wire good and tinned. Flip the pcb and surface mount that bad boy. It's a completely acceptable way of working. I do it all the time with radios and amps. Makes it easier to change values. Put some solder on the pad first. If you ever lift the pad, don't freak out. Use a small knife and scratch off a small portion of the trace and solder to it.

Hmm I too started off with the byoc kits. I think I did the 2 knob vca comp. I then moved on to mad beans pcb. I really started learning by etching his artwork at the bottom of his pdf. These days I get most of my kicks from designing my own pcbs or even circuits based on what I see and study. I can't begin to give you a list lol. I've done several klon, ge fuzz, boosts, comps delays. Amp mod s... list goes on. I've done 3 linear s now and tones of radio mods.

There's a butt load of stuff out there. I would look into something that does side band. Just search for qrp transceiver kits there's literally tons to choose from, from 50$ to infinity

Which pedals have you built? Have you done this fet od? I love the way it looks bc is built almost just like a tube amp, down to the bypass caps. I think I'm going to go ahead and build it. I was hoping sone one could give me a tip on resistor value for 2sk117 bc I bread board this and couldn't get it going.. didn't try very hard, I just didn't feel like busting out the trimmers and data sheet print out.

Qrpkits.com is another good one. Sorry to bombard you, you just got me looking lol

Here we go man! I've got just the thing for you.
www.tentec.com/categories/Kits/
They have kits ranging from 20m-80m band, they also have a popular 2m 6m side band kit. I think if I were you I would get one from here. I could etch pcb all day but some of these parts are very very delicate when it comes to tuning. Building a walkie talkie is one thing but when your talking ham bands I'm not sure an etched pcb would come out satisfactory unless you were very experienced with transceivers. These kits look pretty badass and you can pick and invest what you want into it.
