HERE'S AN EASY BEGINNERS STRIPBOARD PROJECT FOR YOU !

[Dragonfly]

Here's an easy BEGINNERS project I drew up. It's a modified Electro-Harmonix LPB-1 circuit that I adapted to stripboard for EASY CONSTRUCTION ! It also is TRUE BYPASS, and has a pulldown resistor to keep the pedal from making a "popping" sound when you engage it. For eases sake, I made it battery powered (9 volt), and did not include an LED, though these are simple modifications. The NPN transistor can be one of many types: a 2N3904, 2N5088, and 2N5089 ALL work well in this circuit, and it should work well with some other NPN silicon transistors, such as the 2N2222. Don't be fooled by its' simplicity...it really IS a GREAT sounding booster, that is useful in a variety of situations. Just about everyone, beginner or advanced, will find use for an LPB-1 booster.

Anyway, the first diagram is the actual piece of stripboard, and how to lay it out.

The second diagram is how to hook it up into "pedal form"

Heres what you'll need:

*(1) piece of stripboard, 9 holes by 8 strips
*(1) NPN silicon transistor, listed above
*(1) 2.2 MEG resistor
*(1) 47K resistor
*(1) 470K resistor
*(1) 390 ohm resistor
*(1) 10K resistor
*(2) .1mf capacitors, preferably metal film or poly film
*hookup wire
*one DPDT "stomp" switch
*(1) stereo 1/4" jack
*(1) mono 1/4" jack
*(1) 100K audio (log) taper pot
*(1) 9 volt battery harness
*(1) 9 volt battery
*(1) enclosure : Hammond 1590B works great
*(1) knob
*soldering iron, 25-30 watts is plenty
*wire cutters
*pliers, needlenose and regular
*a little patience
*drill and drill bits for the enclosure

MOST, IF NOT ALL, OF THESE PARTS ARE AVAILABLE AT WWW.SMALLBEARELEC.COM .....I HIGHLY RECOMMEND THEM !

ENJOY !!![/color]

that's cool of you to do that for some of the fokes 'round here.
    i have not had a chance to check your post 100%, but it looks cool  
               peace,

Thanks !

its a bit of a pain to draw out the parts the first time, but after you save a "template" of various parts, its pretty easy to make these layouts....

sometimes its hard for beginners to follow a perfboard layout (like on ROG, which is an WONDERFUL site !) , so i did it with stripboard, which is easier to "follow"....and easier to construct !

Make sure you ground the input jack as well!

ive never had to on an LPB1 style booster...as long as the board and the output jack are grounded, its completely quiet...the input jack is grounded through the enclosure.

Still, it's a good practice for beginners to learn because at some point, it will be necessary.  Better to be on the safe side.

youre probably right...i'll add a ground from input jack to output jack on the layout

done...

Cool...this looks too easy for anyone including those just getting feet wet.
 I'ts nice to have your first project fire right up, 'cold water debugging' is enough to age your mind prematurely...when you're like stuck.
 This should save a Newbie a "NOOoooo"...hopefully !!! Plus it's kind of fun to look at, all linear like that, even the drawing helps show...this goes in here...etc.
 Thanks for doing this one...cool !!!

THANKS FOR THE KIND WORDS....nothing is more frustrating for a beginner than not having their first project work...and nothing is more encouraging than having it "fire right up" !

So far ive done stripboard layouts for the LPB-1, a silicon Fuzz Face, the AMZ Mosfet Booster, and Tim Escobedo's Harmonic Jerkulator...i'm just doing some final "looking over" the diagrams to make sure there are no mistakes. My "plan" is to design a website that have a BUNCH of these cool layouts on stripboard, so that those who don't want to "becomes EE's" can easily make their own pedals.

and yeah...they do "look" kinda cool !
