What do they call those?  Egg heads?

[kurtlives]

^chickheads?

Where did you get those mini ones Dan?

[gena_p1]

Where you got such cool chickenheads? =)

This is the Donkey Kong. It's got it's named since I think it sounds close to the famous VIC 64 and arcade game Donkey Kong. It was a real challenge to wire up all the switches and an even more challenging task to tighten the nuts. The notion that the nuts were bigger than the switch diameter did not cross my mind until it was too late. This little bugger is some thing extra when it comes to sound. It sounds more like a synth than a guitar effect. It sounds really wacky. Basically this is the Slactave MKII (thank a mil slacker) but instead of the mix pot and the Oct up pot, all selections are made by one On/off/on switch and 3 on/off switches. IMO I like to turn off the fuzz and only use the square wave to produce clean 1-4 oct down and 1 oct up and mix between them. I also used the LED that flashes faster the higher the pitch of the original tone is. The different sounds are

First switch Fuzz On/Off
Second switch  1 oct down- Off-2 oct down
Third   switch  3 and 4 the switch down depending on the setting of switch two
Forth switch 1 oct down On/Off   

     

Here are some sound samples. The first is my favourite
(My favorite combo) 3 oct down+one oct up+Phaser45+Chorus http://solderman.fatabur.se/Donkey_Kong/DK chorus_ph45_3 oct down and 1oct up.mp3
3 oct down+one oct up http://solderman.fatabur.se/Donkey_Kong/DK_3%20oct%20down%20and%201oct%20up.mp3
1 oct down http://solderman.fatabur.se/Donkey_Kong/DK_1_oct%20down.mp3
2 oct down http://solderman.fatabur.se/Donkey_Kong/DK_2_oct%20down.mp3
3 oct down http://solderman.fatabur.se/Donkey_Kong/DK_3_oct%20down.mp3
4 oct down http://solderman.fatabur.se/Donkey_Kong/DK_4_oct%20down.mp3

And here is some pics.

Wow this thing sounds incredibly cool. Your favorite sound sure is awesome! I hope someday I'll be able to build a more complicated pedal like that one you have made.

They come stock on the F*ender Mini Twin micro amps.

I sent an email to the service dept. and err......"told a little fib"....asking them if they had any in stock they could sell me. Oddly - the service dept doesn't have a part number or mfr for them - but they did have a DOA mini twin on the bench that they stripped the knobs off and sent to me.

Now the hunt is on to find more to purchase. They only fit on split shaft knurled pots (they have no set screw) - so they'd work great on the Futurelec 16mm pots etc.

Hi Dan and everyone
No we don't want to se this thread goes to sleep. So I throw in my Hide 'n Seek Wha. I did not post it here or in pictures because it got a tread of its own. So if some one is more interested in the in depth story look here http://www.diystompboxes.com/smfforum/index.php?topic=77418.0to








BTW there is a Hide'n Seek Ring Tone in a 1590A "coocking" in my computer. Ill guees its due by mid August. So stay tuned folks.

[solderman]

Hi Again all. We defenetly don't want this topic to go dry, so I'll pitch in yet another one. This one is the "That's Swell" DOD FX 15 Clone. I haven't had the time to box it up yet so you have to put up with the guts for now.


The rats nest you se connected to a coin that serves as a "conductive pick" in the set up. Instead of working the switch with your foot as on the original one (the foot switch is connecting S1 to GDN to start the duck and swell phase in the circut) I Just love the conductive pick setup. Its always 100% accurat in timing. You won't be able to be so precise "by foot". Drawback is that you have to have the special "connected pick". Here is the project file and the PCB transfer if some one wants to build it. It's sized for fitting in a 1950A enclosure but can of cause be put in whatever box.
It works verry well and the only change I've made is to put a 1M pull down resistor before the first cap at IN

Guitar volume in a box.
I love this box, it allows me to get that perfect crunch tone out of my Fuzz and then when I turn it off it's full on solo tone! This box gives all my Fuzz/OD pedals a dual life!


Master volume in a box.
This is a master volume you plug into your FX loop on your amp (Hot Rod DeVille). It allows me to crank the amp up a little bit then set it to the volume you want. It works the preamp tubes a little harder. It does not overdrive the power tubes but it sounds better than not having it and you get a lot of control over your lower volume settings.

[MoltenVoltage]

Where did you get those micro pots?  Those are sweet.

You might consider using our tap tempo chip with these sequenced pedals, that's what it does best.  You could even use a taller tactile switch and a mini rotary control to select the speed ratio to keep it in the 1590A.

Great work.

There are actually trim pots with added shafts (see the PDF link in this tread) http://www.diystompboxes.com/smfforum/index.php?topic=77418.0
Thanks for the suggestion. I'll bare it in mind in my next 4017 project.

I've been wanting to throw my hat into this ring for a long time. Since I started building fx I've loved the idea of miniature enclosures. I have small feet, and I don't like carry tons of stuff around. More effects on less pedal board real estate!

Here in Taiwan 1590As are not really available, but I believe the box I have is sufficiently small to be comparable (proportions are much different, obviously). This is my Green Ringer - my most successful small effect so far (I built a fuzz that was altogether too tight, and a GGG mini mixer with two inputs in identical boxes). It has a broken DPDT switch (one set of poles copped too much heat in a previous effect) and a small coil relay for true bypass + LED.

EA tremolo with a few minor mods to suit the components I had to hand.
It's been a while since I designed a PCB layout and to be honest, I was inspired by the other designs on here that put as much as possible on the board. IMHO it really is the way to go if you have board making equipment to hand.
Measuring the drill hole positions was a bit of a challenge, but I was lucky and everything fitted ok, apart from the pot holes which required filing. If anyone has any tips on accurate hole placement, I would really like to hear them!

Now, what colour to paint it......?

I had some blue paint going spare......

[juse]

Nice build!

You might consider cleaning the flux residue off with an acid brush & rubbing alcohol shortly after you solder, before it sets up good. Could save you trouble in the long run. Even the so-called 'no-clean' fluxes should be cleaned off to avoid corrosion, as well as the possibility of reacting with moisture on humid days to create a short. Sticky stuff - can also collect contaminants and become conductive.

[earthtonesaudio]

Agreed.  Many RoHS-approved solders have water-soluble fluxes, which makes them more readily interact with moisture in the air.  Another quirk of some RoHS-safe fluxes is that they're conductive.   

[elshiftos]

Ta for the tip. Just today I was soldering a dr boogie and thought I really should start cleaning the flux off my boards!
Any suggestions for removing the stuff after it's been on the board a while?

Cheers

any hint as to where i might be able to get a schem for this pedal? 

[azrael]

^It's just a potentiometer in a box. A volume pedal.

It's just if you place a volume pedal in the effects loop, it will function as a master volume. If your amp doesn't have a master volume, then it could be useful.

[Taylor]

I think he was being sarcastic. Note the smiley.

Also, "master volume" can have different meanings, but you do know that a volume knob in an effects loop does not allow you to get power tube distortion at low volumes, right? Depending on the amp's design, it can either help you get preamp distortion, or not do much at all. For example, in my Univox 100w all-tube amp, the volume knob comes after the pre tubes, but before the power tubes. It doesn't have an effects loop, but if it did, putting a volume knob there would do exactly the same thing as using the amp's volume knob.

It would only help in amps where the volume knob comes before the pre tubes.

[deaconque]

Sorry, sarcasm doesn't really translate well online.
