Interface. As you can tell already, this upgrade is a serious go big or go home affair, so its no surprise that SD3s interface has been completely revamped and.

Steps with PicturesUnderstanding the bare PCBThe first and most important thing to understand is which holes on your bare PCB are connected to one another. Notice how there are white linesboxes outlining some of the holes. These outlines identify which holes are connected together. Although none of the holes look connected from the outside, the ones which are outlined by a white box are connected together internally. So if you solder any two connections within a box, think of this as soldering those connections directly together. Follow the 5. Vground connections from the Teensy board and notice how both the powerground become connected around the entire perimeter of the board. The orange wires at the bottom of the board send powerground from one side of the board to the other. Header pins. You way also be wondering what all these header pins poking out are for. Well, its simple, those pins are what we snap our wires to using the plastic crimp housing. I have attached images for the full featured PCB. This PCB makes use of every Teensy pin, as well as the CD4. BE multiplexer. None of my modules used every Teensy pin. This board was built just as an example. For example, if you had 1. Each pushbutton would require one header pin that connected to the board, and another one that connected to ground total 2. Each potentiometer would require one header pin that connected to the board, one to ground, and one to power total 3. And I Am Telling You Midi File' title='And I Am Telling You Midi File' />You could reduce the number of header pins needed by connecting the groundpower of the components together. CD4. BEOkay what the heck does this CD4. BE chip do Good question. As you probably noticed from the pin configuration diagram the Teensy only has eight analog inputs. Yikes In some cases like my mixer you will require more than eight analog inputs. The CD4. 06. 7BE easily adds 1. The four red wired linked between the Teensy and CD4. DJ Techtools The largest community for DJ and producer techniques, tutorials, and tips. Traktor secrets, controller reviews, a massive MIDI mapping library, and more. BE allow the Teensy to tell the CD4. BE which of the 1. The brown then sends the information for that analog input from the CD4. BE to the Teensy.

At some point in your studio adventures you might be asking yourself this question do I need to buy an outboard compressor Maybe youve heard that recording with. Those of you who are familiar with Arduino may be wondering why I am using a Teensy instead of Arduino. Four good reasons. One, Arduino cannot act as a native MIDI. You can enter multiple addresses separated by commas to send the article to a group to send to recipients individually, enter just one address at a time. I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you. I loafe and invite my soul. So if you require eight analog inputs or less, you will not need to add the CD4. BE to your PCB. That said, it is nice to have it on your PCB in case you later want to add more analog inputs. The CD4. 06. 7BE chip only costs 1. Resistors on the top right of the board. This is the board I used for my mixer, which includes two LEDs on the interface. It is important you use resistors in series with your LEDs otherwise your LEDs will burn out. Different colorstypes of LEDs require different resistor values usually around 2. Check online to make sure you have coupled the correct resistor with your LED. You will notice I soldered one end of the resistor directly to the header pin. This was a bit ugly. It is best to not include header pins where LEDs will be connected and instead solder these resistors directly to the PCB. Both work, the latter just looks a little nicer. I2. C module module communication. In the top left corner we can see the connections required for I2. C power orange, ground grey, SDA yellow, SCL yellow,  Even if you are only building one module I would still recommend adding these connections for future use. It is important to note that this is the I2. C setup for the master module. The master module requires two 4. SDASCL and power. The other slave modules do not require these resistors, i. Teensy internal pins. You will notice eight headers and two wires coming out of the Teens board. This is because some of the pins on the Teensy board for whatever reason are located internally. We have to add these headerswires so we can access these pins. Snap in TeensyThe last two images show an alternative way of connecting the Teensy to the PCB. If something breaks on your Teensy board it is extremely difficult to remove from the PCB. By carefully cutting the female headers to the appropriate length we can create a port that the Teensy snaps into. You could also do this for the CD4. Engineering Books Ing Sites. BE. The disadvantage to doing this is that your height will increase. On my mixer I soldered the Teensy directly to the PCB see images. On all my other modules I connected the Teensy via female headers. Soldering to the PCBThe video step 6 shows how to solder to the PCB. Ensure each connection has a nice cone of solder securing it. How To Create Wireless Hosted Networks In Windows Vista. The solder should never bridge two holesconnections otherwise you may have some serious problems. Okay that is all you need to know. Follow the diagrams carefully and build your board. You can build the fully featured board exactly as you see it or if you have a better idea what is going on here, add header pins only where you need them. In the latter case, ensure you have planned out where each component will connect to the board before soldering. Know what sizes of crimp housings you have available to help plan out your header layout i. If you only have 1x. Personally, I would advise just building the full featured board shown in the images. Here is a blown up image of the PCB. The Division Bell 1994 on this page. HERE is the next level PCB, the Teensy Monster. This thing is gonna be super slick.
