ok, i posted a long time ago about my problems, but since then, i've rebuilt the whole thing with brand new parts, but the same thing still happens:

at 1-2v, the clock will generate a squarish wave ranging from 100hz to 1.5mhz depending on the voltage (despite the 16mhz crystal). anything above that voltage will just draw a lot of current and not generate any wave whatsoever, but rather just a +2+VDC detected by the scope. if i set the psu to the right voltages according to documentation, it will draw a good .2+ amperes, which is waaaaay off. what's going on here? any ideas???:whazzat:

thanks

schematic: scroll down a bit here: http://www.diyaudio.com/forums/showthread.php?s=&threadid=16296&perpage=10&pagenumber=5
layout: http://www6.head-fi.org/forums/showthread.php?mode=hybrid&t=55352 it's not the same as mine... well, not nearly, but i used it to double check my own layout and made sure it matched both that and the schematic. i doubt i would have gotten it wrong twice in a row unless i misread it or something:-/

Well, I hope you understand I will not search for errors on the SMD-mess Glassman made 🙄 🙄 🙄

Elso!

Don't you start this "ur" thing too, please! It's is difficult enough this multi-cultural communication without people inventing their own vocabulary 😉

My health is fine, thanks!

Sorry Janneman,
W8 a minute!
Yap, I am 2 much on chat, urvw.
Glad to know ur asl is same as mines.
Sorry again for my chat shorthand
c u, hahahahaha, LOL
😀

BTW did you build my clock?

That Kwack Clock looks like a bit old design now.
In electronics 2-3 years is a very long time.
New, smaller and better components are to be found all the time.

Maybe you should look for alternatives.
Maybe someone has done an up-to-date fresh version
of the same circuit or a similiar concept.

I am not saying Kwack Clock is bad ( I understand not much of digital circuits )
I am saying there might be better performing and modern circuits.
Does not hurt to look for something better ....

Perhaps you could enlighten us as to the paticular aspect of the design you feel has dated.

Hi Lineup,
1) Why smaller components? Soldering SMD is NOT for the novice!
2) A more modern Colpits oscillator?
3) Why criticize a circuit if you don't understand much of digital circuits?
4) It's spelled KWAK-CLOCK
:smash:

Good try, to twist my opinion into your advantage, Kwack.

But dear readers, dont let yourselves get twisted.
I wont!
Stay to the fact.
And dont let anyone put words into my mouth,
that I never have said.
------------------------------------

Kwack:

1. SMD, where did you get that from?

2. Why Colpitt?
(Mr Colpitt did spell his name this way, as far as I know. See point #2 above.)
There are maybe 5 alternative oscillators types.

3. I understand someone having trouble here.
And that Kwack clock is an old circuit, by electronic standards.
A lot can happen in 3-4 years.
New and better stuff arrive all the time, ya know!

4. Spelling has never been for me.
Hope you get my message, anyway.
Nobody else has complained, yet.


Regards dear ClockMaker

Kwak-clock

1) SMD is smaller. You asked for smaller components, but why???
2) Other oscillator types are also many years old
It's spelled Colpitts BTW, my wrong too but yours also, lol.
http://en.wikipedia.org/wiki/Colpitts_oscillator
3) Go hunting the new and better stuff, I am most interested 🙂
Any clue? 🙄

Off topic: nothing on ur site lineup!

In the old days my name was spelled Quack. But we are modern now.

My first try was a point to point Kwak 7 (i don't dare to use p2p anymore now) Works fine.

Last week finished a +/- 10 by 6 cm pcb, drawn with simple but fine TCI software. SMD and regular parts on a single sided pcb, and added a clock divider too. I will soon show a screenshot of it. (work on a Linux-PC at the moment)

Will try pcb next week, have to get some parts first.

Hi tubee, p2p works though that gives me the jitters with SMD parts!
Any reason why you did go for SMD? I deliberately went for through-hole parts for DIY. Even then some guys manage to burn the FET resulting in an inoperative circuit. So the J309 in SMD? (SOT23) If I cough it's gone 😎

So....

What news on the original point of the thread??

Elso, i have been reading your colleage's decoupling guidelines (Guido's) thats why.

Made some small errors though, discovered them after the first PCB was ready. The signal lenghts can be made shorter in SMD, but with p2p you can get very short lines also whith a keen layout.
The fet will be a regular TO92, as the BC's and TL's, and a regular 74HC163. The Max is in SMD, with many ceramic decoupling caps, and some R's.
Almost all SMD parts are allready soldered on pcb.
