Now that the Circuits have all been Built. we can wire them all together. This is really quite straight forward. Simply wire everything in parallel. This means that the power wiring for each module goes directly back to the source. This allows us to not have voltage drop across each component.
make sure to leave plenty of extra wire so that you can place knobs and connectors where ever you want in your enclosure.
I will return shortly to show how everything is mounted in the case and give it a nice run through!
This circuit is actually very very simple to assemble and shouldn’t really take you more than a half hour tops to build.
It comprises of a board with pads for a few knobs and jacks, as well as a few extra parts so that you can play around and add modifications to the circuit. The PT2399 is a chip that is found in MANY guitar delay pedals. It is a digital chip that emulates the analog bucket brigade. As delay times get longer, the audio degrades. This can be used to great effect when you start to play with long delay times and feedback.
In this video I build the PT2399 Dev board, I do not show me building in any mods. The reason for this is I want you to feel free to experiment with the board. you won’t harm the chip its quite robust and is great fun to play with “circuit bending” it. just basically wire up a momentary switch (included with the kit) and touch the leads to any two points you find interested (by poking a piece of wire around you may find the chip behavior act interesting). For the final circuit I went with the suggested Feedblast the warp and the feedback as pictured below.
Yes thats right! Anyone can build the 555 timer LFO… and to prove it, I let my 8 year old daughter do it! This was Elly’s first time soldering and she enjoyed it immensely (even with a minor mishap!) If she can jump on the Synth DIY horse, SO CAN YOU!
The 555 Timer Oscillator from Synthrotek will be a modulation source for our upcoming Delay Dev kit circuit. (and other circuits as we will keep this modular!)
the Idea is to use this to modulate the rate of the delay board.
For this project, we won’t be hooking up power just yet as I plan on daisy chaining the power off of another circuit first.
we also will not solder on the attenuator just yet as we will be using wire so that we can place the board more efficiently inside of the case. You can buy the 555 Timer LFO HERE—> Synthrotek Store it’s only $15.
Now that we have established some basics it is time to take a look at what we are actually going to be doing in this series. I want to start off by giving a list of the Synthrotek Kits we will need in order to complete this series. You can purchase these kits as we go along or all of them upfront (getting them upfront is not a bad idea as we will likely have some live Q&A sessions and it will be nice for you to have the kits ready).
For some time now I have really loved the Brute series from Arturia. I also tend to be the type of person to just never be satisfied even when things are going great. So today I decided to modify my brutes. The one feature I always wished the Minibrute had was LFO output so that it could be used to control my modular. Well today I rectified that problem with a simple mod that you can do with very basic tools.
All that is needed is a few mono 1/8″ jacks, some wire, some solder, a soldering iron, a screw driver and a drill.
Here is a list of the solder points and what they are. The video below details not only how to perform this mod, but how to actually find these types of modifications yourself!
