PWM LED Dimmer Stripboard VeroBoard Layout (Orig. By Dave L. Jones)


Dave Jones did a cool little circuit using a 555 to dim the LEDs on his Mantis microscope. Obviously this little circuit has a lot of uses so I thought I would make a little stripboard layout for it.

There isn't much to say about it as it has already been covered in his video (linked below)

so here you go.

1970's wah wah pedal Stripboard Veroboard Layout


Obviously this is not one of mine but one taken from a magazine from 1970. it uses germanium transistors however if you can't find them or they are too expensive just try some general purpose ones like 2N3906 instead of the ones listed.

There are a few odd values that aren't really readily available - just get the ones nearest to them - like in the case of the 50uf capacitor substitute it with a 47uf one and so on.

8 Bit Guitar Fuzz II Effect Stripboard Veroboard Layout


I wanted to make a kind of brutal fuzz pedal for a song I'm working on that needs a really nasty sounding lead bit so I designed this little beast - it was a very very quick circuit so I didn't add any pots or anything to it however I think you will like it (if you like this kind of thing of course)
it also sounds a little bit like the type of Fuzz the Smashing Pumpkins used in siamese dream 

I have uploaded a little sample of it in action HERE

I hope you will add some mods to this - if you do please let me know!
I'm calling it the Quadraspazz Fuzz

Low Battery Indicator ( 9v ) Stripboard Veroboard Layout


I was in the middle of designing a little 9volt battery operated music thing and I thought it would be nice to have a little battery indicator to tell me when it was getting low.
Once I made it up I thought it might be a cool little thing to share on here so you could add it into stuff like guitar FX and so on.

it has 3 states:
1. if the battery is good then the LED doesn't light
2. between 7.5v and 6.4v the LED flashes to warn you it's getting low
3. below 6.4v the LED stays lit

I know there are specific ICs for this purpose however I like making my own "solutions"
Anyway hope you like it.
