Welcome - Please Read

Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

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!

Frequency Meter Stripboard Layout


I built this as a rough frequency meter to make sure a bunch of oscillators were oscillating in the right ballpark frequency.
it uses the lovely 555 timer IC.

it responds best to squarewave signals (maybe triangle too, I forgot to test it with triangle waves)

Quick And Dirty Laser Driver Stripboard Layout


This was just a quick little circuit I built to test all the salvaged CD/DVD lasers I have.
essentially it is a adjustable constant current power supply.

the Vin is 7.2 volts.

Simple Audio Mixer Stripboard Layout


this is a quick project I made for another project I'm working on but I'm sure people will have uses for this so here you go.

it's also worth noting (as I have before) the purpose of C1 is to limit the bandwidth of the Op-Amp - in this case I've used a value to stop any hiss however you can experiment with the values and make a low pass filter - the higher you go the more it cuts off.

Proper Op Amp Termination


I've been designing a sampler recently (sorry, there won't be a stripboard for that, it's way too complicated!) however I was using a quad opamp for a part of it but I only needed 3 of the op-amps which gave me the idea to post a little tutorial on the correct way to terminate unused op-amps and a brief explanation why (I'm sure there are very in depth youtube videos/documents elsewhere)

the extremely brief reason to terminate a op-amp correctly is that it may draw extra current or it will pick up noise (or both)
