Build Your Own Clone Message Board

Following on from Dragonfly's "Just a Bunch of Ideas" I though I'd perf my way through Tim Escobedo's Simple Circuit Snippets:

http://www.geocities.com/tpe123/folkurb ... l#lofomofo

The web site appears to have been pulled, but I have all of the circuits on file. I did e-mail Mr Escobedo some time ago for permission to use the schematics and notes on this forum but I've had no reply as of yet. If probelms do appear, I'll pull these schematics and do my own ones.

As there are over 40 circuits to do, it will take a bit of time to do them all. I would like to do one per day, but due to a heavy work schedule this might not be possible.

Hope you enjoy them.

Whatever happened to TD's Group Buy on Perf?

tonmann, have you ever thought of changing your ID to THE man? Thanks for these, looking forward to the rest (when you get the chance) and trying them out. I still have a hard time transferring schematics to breadboard, but vero to breadboard is a little easier for my simple mind.

This is so awesome. Great idea, tonmann.

Here is a more stable link to Escobedo's stuff:

I built the Digital Octaver fuzz and it rules.

+1 .

Thank you, tonmann. You are the King of Vero .

cool stuff

btw all geocities pages are gone now. there's probably a lot of useful info that got pulled from the internet in the past week.

Tim's stuff is great. Coupled with tonmann's vero expertise, this is gonna be on popular thread.

Once again, thanks for the kind comments.

Today's is the Bronx Cheer:





You should be seeing seven cuts (don't forget the cuts at e4 & h4) and four jumpers

Really really nice of you, tonmann. I'm ready to send the check now. Thanks very much.

Geek I hope this isn't the man in Prague on the trampoline again (the Czech bounced)

I will be away until the end of the week (watching Germany beat the USA at ice hockey), so I've just finished the next two:





A lot of cuts, so I've done the reverse side:








For the Cinnabar you should be counting six cuts and three jumpers

Yah so how did that work out for you? ....Nicht!

All in good fun as a fellow sports enthusiast!

Sorry Barry, you spoke too soon. Final tournament standings:

Germany
USA
Slovakia
Switzerland

And just to celebrate - the next circuit:





10 cuts and 5 jumpers

Tonmann, you rule. I vote veroboard gets renamed to Tonmann-Board.

Next up is the CMOS drive:





Seventeen cuts and six jumpers. I used the fifth inverter instead of the second to make the circuit fit onto a reasonably sized vero board.

Note the 3V power supply

Another CMOS circuit:





There are 14 cuts and 8 jumpers, I've decided to stop being lazy and do a reverse side layout for all of the larger boards containg lots of cuts:



I've had a couple of queries about component labeling. I would love to label the components on the schematics, but this would take a bit of time (one of the constraints I have set myself is that a circuit board takes no longer than 30 minutes from start to finish, excluding posting to the forum). I tried to keep labeling flowing logically i.e. left to right, top to bottom; this includes the pots - in this schematic P1 is the "fund." pot, P2 the "tone" pot and P3 the "volume" pot. Thus P1_3 is the third lug of the first pot, P2_2 is the second lug of the second pot... and so on. Again, the time constraint means I won't be doing wiring diagrams for these projects; if anybody wants to build one of these projects and is completely stuck as to how to wire the out-board components - a PM to me will solve the problem.

There are 4 cuts (a8, c4, d4 and f8) and one jumper.
The second diode (D2) is a 9.1V zener diode. This is used as a protection diode for the FET.

You can use any 9.1V zener diode.

You can also use an LED instead of the diode. Remove the diode and insert the LED; anode to d6 and cathode to c6.

You could also do without the protection diode, read below.

A word of advice to novices: MOSFETs like the 2N7000 and the BS170 are suseptable to damage if there is a large voltage difference (about 20V) between the gate and source. Although this isn't going to happen with a 9V supply, it can be caused by a static electrical discharge during handling, so make sure you are not wearing nylon clothes, walking barefoot across carpet or have the cat on your lap when handling these FETs. Although using an earthing strap attached to your wrist seems a bit excessive, grab hold of something that is grounded (a metal water pipe) just before you handle the FET.

Note to self: remove shell suit before handling FETs.

Static electricty from a Liverpudlian business suit also does strange things to your hair !

Even simpler than yesterday's circuit:





One cut and two jumpers.

Today's offerering, a FET driver:





9 cuts and 5 jumpers. The reverse side:



With the odd values for R1 & R2, I would imagine that R1 can be any value from 470 kΩ upwards and R2 a standard 47 kΩ.

I like this one, tonmann. Thanks once again. What are the pot values? Looks like P2 is 300k? Is P1 300k as well?

These are great! Thanks!!!

Strange values !! I'd go with 250 kΩ pots

Next in line are three bootstrapped circuits:



If 2 MΩ pots are difficult to find, 1 MΩ pots should be OK.



Four cuts and five jumpers.



Two cuts and two jumpers



Four cuts and three jumpers
