KAT Treble Booster TAGBOARD layout

My good friend Dan White-Lock Jones sent me one of his amps to play around with so the 1st thing I did was add my favorite effect - the treble booster. I laid it out on tagboard to fit in with the rest of the amps insides so I thought that I would share it here.

the amp itself is a 2 channel beast - 1 channel is voxy and the other is a stripped back dumble. it's worth noting that Dan thoughtfully puts bleed resistors on the HT capacitors so there are no nasty surprises waiting inside! 

Brian May BC149 Orange Label Treble Booster Stripboard Layout & Schematic

 I couldn't find much info on the electronics in this one so I had to trace it from various internal pictures around the internet. in some of them, there is a 100 ohm resistor between the battery and the PCB so if you have noise issues - add that. here's a good site for info on Brians Boosters history of brian mays treble boosters

Why I Rarely Post Projects Anymore

Alot of my projects are things I've thought of (unless otherwise noted) and over the years I've gotten a bit pissed off with people building my stuff, selling it on without even bothering to credit me in anyway. I don't care if people build/sell this stuff but one of the unwritten rules of open source stuff is that you always credit the original person.

I've seen many of my projects floating around being sold by various people with no mention or link to where it came from and it put me off sharing stuff so I simply stopped bothering putting effort into posting here. But seeing this on eBay was the straw that broke the camels back. 

people within "open source" give you stuff they've spent time and money developing - the very least you can do is respect them enough to link to the original post and/or credit them ESPECIALLY if you're making money out of them.

20 Second Handwashing Timer (for Covid-19) stripboard layout

quite a simple project, during the Covid-19 coronavirus outbreak, one of the pieces of advice we've been given is to wash our hands for 20 seconds. so here's a timer circuit to help you do that.

"sw" is a push-to-make momentary switch, once you press the button, the LED illuminates for about 25 seconds (I added a few seconds to the timer to allow time to put soap on your hands). then just wash your hands till the LED goes off.
pretty good way to make sure your kids are washing their hands for long enough.

Stay safe.

Dual LED 3PDT Stomp switch daughterboard PCB layout

I haven't done stripboard construction for a long time, truth is I've been busy with my engineering work, my bands and my mixing work to sit down and do stripboards but I've been doing PCB layouts for little projects and I thought I might aswell post them here

first of all is this little daughter-board for your guitar fx builds that will change a dual colour LED from red to green depending on the switch state; so you can use it as some kind of channel indicator or simply just have a LED to say whether the pedal is engaged or not

here is a link to the rar of the .PDF files (the only way I can seem to get boards to print at the right size) http://www.mediafire.com/file/aszhtwj0vd9xcc0/Stomp.rar/file

Here it is in a pedal I made years ago (https://paulinthelab.blogspot.com/2014/06/green-wizard-guitar-overdrive.html)

Amptweaker Defizzerator Stripboard Layout

I went to the shop yesterday hoping to buy 2 Amptweaker Defizzerators for a recording session but of course; they only had 1, so I bought 1 and reverse engineered it. it's a passive circuit so you get a bit of loss and I may work on a buffered version at a later date but for now;
enjoy.

May Queen Overdrive (originally by Runoffgroove.com) Stripboard layout

I used to make this pedal a lot and sell them on eBay so I thought I'd revisit it as it seems that I sold the one I made for myself too.
Anyway this is a pretty cool effect, it has a lot more drive than a standard treble booster and it layers up really nicely.

Red Wizard Fuzz Stripboard Layout

this is the 3rd guitar effect in the "wizard" collection.
As anyone who has followed this site for long enough will know, I always make my pedals very minimal when it comes to controls but if anyone does add to this circuit I'd love to see what you've done.

anyway, enjoy.

Maxon Treble Booster Stripboard Layout

I came across this interesting little thing so I thought I would make a clone of it.
it's a maxon treble booster.

they also did one called the power booster and as far as I can see the only differences between that and this is that the power booster has 2 470n capacitors in place of the 2.2n capacitors.

Electret Microphone Preamp Stripboard Layout

someone asked me to do this, so I did. it's a useful little circuit to power those little electret microphones.
