End of the crowdfunding campaign: what's next?

Here it is! The crowdfunding campaign is over, with a lot of success!
Thank you all for your support, Coda Effects is on the good tracks thanks to you!

crowdfunding ended

Let me show you some numbers:
In this post, I want to present you how I am going to schedule everything. As mentioned on the project webpage, I will write blog posts about the perks and pitfalls of making a series of pedals. One the pitfalls if to make an impossible-to-follow delivery schedule for sure!

Here is my schedule:
  • Receiving the money (one to two weeks): I will be then allow to see how much is left after the Ulule, Paypal, and French state taxes are off the collected amount of money. Indeed, almost 23% of the money will go to these different taxes. (No worries, I made the calculations before :) ). It should take one to two weeks to get all the money ready for ordering the parts!
  • Ordering the PCBs, enclosures and components (one to two months): one of the most crucial step! Thanks to the prototypes I have already made and my experience, I already selected a list of reliable suppliers. However, the delays can be quite long due to their localizations (USA, China for the PCBs, which can cause delays due to customs). At this step, some "surprises" can also happen and delay the shipping of the PCBs / kits / pedals. Everything should be fine with the suppliers I selected, but you never now! One to two month seems like a reasonable delay for ordering and receiving all the parts.
  • Drilling the enclosures, making the kits & effects (two weeks to one month): the fun step! I will do my best to make it as quick as possible, but always with great care about the project. I will have 27 pedals to make, and everything else will be kits (which implies only drilling). I already thought about tips to make it easier and quicker, which I will share with you in a next post.
  • Making videos and build doc (one to two weeks): before sending the kits, I really want to make a tutorial video to show you how to assemble your kit. It will prevent a lot of mistakes I think, so I think it is worth the wait! 
  • Shipping everything (one week + shipping time): I am currently evaluating which shipper I should use, for now I am considering the French post offices, which are quite good regarding tracking, delays and costs.
There it is! It is quite a lot of work to do. The maximum delay time is around 4 month (February 2017). I know it is quite a long time, but I hope to make it as quick as possible!

You will of course be informed about how it goes on a weekly basis.
If you have any suggestion or comment to make, do not hesitate to post a comment!

Tonebender MKIII clone (Aion Electronics Phobos)

Here is my last build: a Tonebender MKIII clone! The tonebender was initially a derivative of the Fuzz Face, a bit closer to an amp distorsion than a fuzz. (read my post about the different types of fuzz) It became quickly famous thanks to a lot of guitarists like Jimmy Page or Jeff Beck.

The MK2 version used two germanium transistors to get fuzzy tones. However, due to the nature of the circuit, the quality of the fuzz was very dependent on the transistor's gain and characteristics, just like in the Fuzz Face. In order to avoid the selection of transistors, the Mk3 version used 3 transistors, so that the quality of the sound is less dependent on the germanium transistors used. Here is my version:

Crowdfunding campaign for the Montagne Tremolo and Dolmen Fuzz

My crowdfunding campaign for the Montagne Tremolo and the Dolmen Fuzz is finally out there!

The Montagne Tremolo is my final version of the tremolo prototype I showed you in a previous post. It is an analog optical tremolo with tap tempo and 6 different waveforms available, thanks to the TAPLFO digital chip.

The Dolmen Fuzz comes from my love for EHX Big Muffs and especially the green russian version. I tried different prototypes and circuits, and it is quite close to a previous build I made as well.

Create your own pedal company: good or bad idea?

If you already have made a few pedals yourself, you surely have thought about selling them or at least build some of them for other people. Create your own guitar pedal brand seems like a good idea on paper, however there are many pitfalls.... Lets talk about it!

Disclaimer: I make effects myself, and this post is not intended to "kill competitors" (with my 30 pedals a year...)! On the contrary, I think it is way better to be transparent and to talk about it: this is only my opinion, and feel free to express yours in the comments section :)

It is a complex matter that is not always easy to discuss peacefully because of money, and there are many different opinions on the subject. It is also the source of really long yet exciting threads on DIY forums (check this one!). The simplest option for me is to discuss it from my point of view as a builder. Thus, I will talk about Coda Effects, and well, just once will not hurt, about me, and give you some tips if you want to jump in it!

Early 2013, I started to show interest in guitar pedal building: after opening a Fuzz Face, I was quite astonished by the simplicity of the circuit (there is almost nothing in there!), and I realized that building guitar effects might be simpler that I thought.

Boss Tap Tempo DIY

Here is my latest build, a very simple tap tempo pedal for a Boss DD7 pedal (or any other pedal with external tap tempo). It is very simple : one mono jack, one momentary SPST! Very easy build, I think it is the perfect build to begin with DIY! Tap tempo is very useful if you play in a band, so I think this is really a great way to improve your beloved DD7 guitar pedal.

I used a Hammond 1590LB enclosure, which is really small. However, I did not centered the momentary switch because of the lack of space.

Eagle for making guitar pedals PCB: getting started (part 1/3)

Sometimes, especially with complicated builds with a lot of components, or when you have to build several times the same pedal, it is easier to use a printed circuit board (PCB) than veroboard or turrets board. A PCB is easier to assemble, and it prevents from doing many mistakes that can occur when using veroboard: false contacts, misplaced component, complicated wiring involving a lot of wires...etc.

"Eagle" is the name of a beautiful animal, but it also stands for "Easily Applicable Graphical Layout Editor", the name of a famous software that helps you to conceive and make printed circuit boards (PCB). I already used it a lot to make PCBs. For instance, I made a few Klon buffer boards with it. I decided to write a serie of articles explaining how to use it to make PCB for your guitar pedals.

Article parts:
  • Getting started (you are reading this one now)
  • Tracing the circuit (to be published)
  •  Creating the PCB layout (to be published)

Become free to make PCB like you want with Eagle

Why using Eagle?

There are many different different software to create PCBs that are available nowadays: DipTrace, KiCad (open source), Express PCB, Fritzing... Why using Eagle instead of these ones?
Well, there are several reasons.

Eagle is free. If you are using Eagle for your personnal use, it is a freeware. Of course, there are limitations that come with the freeware version, but they are not really a problem when it comes to guitar pedal PCB development: maximum size of 100 x 80 mm (4 x 3.2 inches), which is really big for a guitar pedal PCB, only 2 layers maximum (well, we are not going to use more anyway), and one schematic maximum per project. If you want to sell your projects, you will have to buy it, but for simple projects like guitar pedals, the Lite edition is enough and costs only 69$! If you need to buy it, respect the developpers, do not be ill-eagle (badum tsss) and buy it.

Eagle is well documented. There are a lot of books, websites, videos that are dedicated to Eagle software. If you ever encounter a problem, or if you do not know how to use a precise function, you will always find a solution somewhere. I will write a list of useful websites down this post.

Eagle has the most complete libraries. When creating a PCB, you need to specify what component you are going to use in your circuit. Is it a small 1/8W resistor, a big 1W one?  Is it an electrolytic capacitor or a tantalum one? You can imagine that it is very important to precise it in order to have the good component "shape" on your PCB. In order to do that, you have lists of components that are called "libraries", which contains hundreds of different components! Eagle has a lot of libraries for all kinds of components, and some libraries had been made especially for guitar pedals!

Eagle is easy to use. Most PCB softwares are easy to use, and Eagle is too! The "graphical" word in "EaGle" simply means that you have a wysiwyg interface. The interface is easy to use, and let you directly move the components on the board. Last thing, it works on windows and mac, which is nice if you are using different operating systems.

Convinced? Let's get started!

Installing Eagle

Download Eagle on CadSoft website, and install it as a freeware (except if you are going to sell the PCBs you make with it)

The libraries

When you create a PCB, you need to be very precise about which component you are going to use. Indeed, if you put a wrong reference somewhere, the spaces between the lugs can be too short / too long, the component could be too big to fit the PCB...etc. For instance on this PCB:
Superfuzz PCB circuit board
You can see that every component fits perfectly its location on the PCB. This is because when conceiving the PCB, I used the correct references for each components.

A library is simply a list of components referencing components sizes, values and shapes. Eagle comes with already a lot of libraries pre-installed. Some of them will be really useful (Resistors, Capacitors, Inducors (RLC), transistors, supply...etc), some of them not (Zilog microprocessor devices?).

Some libraries had been created specially for guitar pedal PCB making:
Gauss Markov library: very easy to use library with a lot of useful components.
Madbean pedals library: Brian (owner of madbean pedals) made available libraries for making guitar pedal PCB.
I strongly suggest that you download these libraries. They are easy to use, and contains all the basic tools that you need for making guitar pedal PCBs.

To install a library, unzip the files, and copy the .lbr files in the "Eagle v7.2/lbr" folder. It is in the applications folder on mac, or in the program files folder on windows.

Then, open Eagle. You should have a window like this, which is the control pannel:
eagle control pannel
You can see that there is a "Libraries" folder that can be expended. It contains all the libraries that you have in the "lbr" folder, including the ones you just downloaded and copied.
To tell Eagle which libraries you are going to use, you need to expand the "Libraries" folder, click right on the library you want to use and click on "Use".
Eagle how to use librairies
You can see that you have a quick description of the library on the right. It can help you sometimes to choose whether you want to use a library or not.

Ok so the big question is now... Which libraries should we use? Either you can use every library, but you can easily get lost with the number of different components available, and redundancy of some components. In my experience, I only use a few libraries compared to what Eagle is offering... Guitar pedal making is quite simple electronics, and does not require a lot of differente components.
Here are the libraries that I use when making a PCB:
  • Gauss Markov libraries (all libraries)
  • Madbean libraries (all libraries)
  • belton-engineering.lbr (if you are using tubes)
  • con-jack.lbr (if you want to implement DC jack on your PCB)
  • diode.lbr
  • ic-package.lbr
  • led.lbr (you will only use LED3MM or LED5MM (classic 3 or 5 mm LED) or DUOLED if you want dual colored LED)
  • linear.lbr (IC, OP amps)
  • pot.lbr (potentiometers, nothing else you stoner!)
  • rcl.lbr (dream library with all resistors, capacitors, inductors)
  • regulators.lbr (voltage regulators)
  • supply1.lbr and supply2.lbr (mainly for the ground symbol)
  • switch.lbr
  • transistor-fet.lbr, transistor-neu-to92.lbr, transistor-npn.lbr, transistor-pnp.lbr, transistor-power.lbr, transistor-small-signal.lbr, transistor.lbr (you should have almost every transistor now!)
  • v-reg.lbr (voltage regulators)
OK! That is already a lot of components, and should be largely enough for any guitar pedal circuit! And if a component you absolutely need is missing from these library, do not forget that you can use other libraries, or download libraries online!

Now we are ready to start!
First we have to trace the schematic... in the next blog post!
