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) https://www.mediafire.com/file/1z03goq9bxl2fho/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.
I have been quite busy with recording music - my bands second album (on a real CD not a CDR) and other bands which is one of the reasons that things have slowed down on here - I've also been working on a lot of high voltage industrial designs so I couldn't really share them!

Where Have You Been?!

as you may have noticed, I've not posted any new projects on here for ages; well there's a few reasons for this.
1. A label released my bands album last August (see previous post shilling it) and leading upto that I was spending a lot of time recording it and mixing it etc. and after that, promoting it.

2. Google screwed up my domain renewal - I had it set to automatically renew as with previous years, my card details were up to date however they arbitrarily decided to not automatically renew it and not warn me so one day I noticed my stats had dropped to zero and they just won't let me renew my domain now - I've spent hours and hours going through their circular "help" menus. I've tried to contact anyone but obviously there's no one to contact and this completely sapped my enthusiasm for this site for a good few months.

but most importantly;

3. I can't think of anything to make, I like to keep these projects moderately easy for the sake of people new to the hobby or people who just want to do weekend projects. normally I would just do some kind of audio related thing when I can't think of anything but my friends at tagboardfx have usually beaten me to anything guitar related - sometimes I will do something they've done if I think I can make it more compact or I have the original pedal and I can check unknown resistor/cap values (like the Nathan East pedal for example)

Anyway if you can give me some suggestions or ideas of stuff to make/design, I can start doing some new stuff. not limited to audio stuff, test gear, LED stuff etc. welcome.

TL:DR - Google is shit & suggest stuff to make

My band has an album out Double Negative - When We're Gone

sorry for the non-electronics post but this is a big deal for me; recently my band were signed and even more recently the pre-order went live so I hope those of you that like skatepunk (bands like NOFX etc) will check it out. you will hear alot of the effects and studio gear that I've posted on here as stripboard projects on this album, most notably the microphone preamp, the treble boosters, the overdrives and so on.

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.

Piss Off batteriser

when doing the admin part of this site,nothing infuriates me more than having a company trying to advertise their snakeoil products in the comments section.
I often get comments where someone has copied a bit of the text from my blog post and then shoved a link to some crappy product after it and usually I just delete it but given the fact that Batteriser has been so underhanded and dishonest about everything they do and claim - I thought I would call this one out.

Dave Jones from the EEVblog has debunked their product in just about every way imaginable and they've done some hilarious reply videos to him where some "engineer" is sat at a table with an oscilloscope hooked up to its own 1Khz reference/cal signal (with very badly compensated probes), some wires and boards and a suspiciously new and cheap looking soldering iron; explaining why Dave is wrong. then, when that failed they just paid people to downvote his videos.

so Batteriser, do not advertise your shitty, useless products on my site.

Very Accurate 10volt and 5volt Reference For Testing Multimeters etc. Stripboard Layout

I thought this would be a good project to keep around to see if my digital multimeter has drifted out of calibration.

I power it from a normal bench power supply but it would probably be better if you used 2 9v batteries in series.

The LED on it displays when over 100mA is being drawn from it - basically if the LED is lit disconnect it or things will be getting very hot!

I tested it in free air with open windows over 2 hours and it was very stable so I can rely on it.

Linear Tech do a few different drop references for this IC
the 2 I've tried are the 10 volt reference and the 5 volt reference
the part numbers are
10 volt reference; LT1021BCN8-10
5 volt reference; LT1021CCN8-5

it stayed at 10.0006 for over 2 hours - the least significant digit moved around but that's 10's of uVolts!
