The RHS is pretty good, congratulations!
For the LHS you're attempting to use a floating (i.e. neither terminal grounded) 12V power supply, to synthesize -3.4V_with_respect_to_ground and +8.6V_with_respect_to_ground (3.4 + 8.6 = 12). I recommend you connect these supplies to two circuit "stages" . Stage1 is an NPN transistor circuit that takes (0V, +3V) inputs and produces (+8.6V, 0V) outputs. Stage2 is a PNP transistor circuit that takes (8.6V, 0V) inputs and produces (-3.4V, +8.6V) outputs. Or you can zener clamp the high level of stage2 so its outputs are (-3.4V, +3.4V).
It's a shame you went straight to dead-bug-on-groundplane soldered implementation, without first building on a solderless plugin protoboard. In its current form, trying out modifications will be difficult.
Yes, perfboard, breadboard, protoboard. These are all correct although "breadboard" often implies the solderless type like this (more info here).
You connect a resistor by bending it's leads and pushing them through the holes. Then you solder them onto the board on the other side (you know what resistors look like right?)
Usually I place all my components on the board and then wire the components together according to the schematic. Here's an idea what the back side might look like.
In the end it is rare that the board and the schematic look at all similar.
Do you have all the components you need?...
Nevermind that for now... To Youtube!!
There is soooo much material on youtube. I searched "how to populate a perfboard" and clicked a random vid. Looks promising. I didn't watch the whole thing, but clearly it's related to what you're trying to learn. Likely there are better tutorials, it's just a matter of searching and watching.
Good luck! Don't be afraid to break things :)
Yeah you've pretty much got it. The controller you linked is the newest version of the teensy, and while it will work fine and will be more upgradable, since you are on a budget you could use any of the teensy boards for this. I would probably just a teensy++ or 2.0. As far as upgradability goes, it depends on what you think you might want to add. For comparison, here are the specs for the ($30usd) teensy++2.0(www.ebay.co.uk/itm/Teensy-2-0/221541256601) :
8-Bit AVR Processor (AT90USB1286)
128K Flash Memory, 8K RAM, 4K EEPROM
USB Can Emulate Any Type of Device
Single Pushbutton Programming
Arduino Compatible
8 Analog Inputs
46 Digital I/O Pins
9 PWM outputs
and the ($20 usd) Teensy 2.0 :
8-Bit AVR Processor 16 MHz (ATMEGA32U4)
31.5K Flash Memory, 2.5K RAM, 1K EEPROM
USB Can Emulate Any Type of Device
Single Pushbutton Programming
Arduino Compatible
12 Analog Inputs
25 Digital I/O Pins
7 PWM outputs
note the difference in analog (faders, knobs) and digital (buttons, switches) IO pins, and think about what you might want to add down the line to decide.
You can use any Teensy controller, arduino, any arduino clone, or any microcontroller that says it has a teensyduino or arduino compatible bootloader. Almost all of the controllers on this page would be suitable for the application I've described.
A breadboard is a rectangular plastic block that is covered in holes with contact clips inside them that you push wires into to build a prototype of your circuit before you do any soldering. It consists of two power "buses" (common contacts) that run down each side, each with a positive and negative hole. In the center are two banks of holes that are arranged into rows of 5, in which all of the holes in each row are connected.
This probably sounds pretty confusing but they are very easy to use, and allow you to quickly build, troubleshoot and test your design before soldering anything, and when you do solder, you can just go piece by piece from your breadboard. This video actually shows a light-controlled midi controller being put together on a breadboard using a Teensy, and shows it interfacing with ableton in real time. Take note of how the power buses on the sides are used, and how the board sits over the ravine, otherwise all pins opposite each other would be shorted to one another.
This page explains how breadboards work very well. In the videos of the teensy on the breadboard, the controllers are the version with header pins to be used with breadboards. This will make it much easier for you to prototype your design, then when it works how you want, you can actually transfer it to a "permanent breadboard" that has holes through the board surrounded by solder pads that you will solder you circuit to once you drop all the wires and teensy pins through the board. If you get one like this that has the exact same layout as a standard breadboard you can literally lift it off the breadboard and drop it into the solderable board if youre gentle. If you can get scrap wire and solder materials (be sure to watch a few videos on soldering ICs and microcontrollers, as the teensy really is teensy, about 17mm x 35mm, so you can imagine how close the pins are. Soldering really isn't difficult if you are patient and prepared though) and build you own enclosure, you can easily keep this under budget.
EMT's are awesome! Even without the contest I've always thought EMT's are awesome!!!
If I have to link something, I'm going to go with this breadboard
A great way to get started with this stuff is through a company called SparkFun based out of Boulder Colorado. They sell two kits both for about $100:
These kits come with all the sensors, LEDs, transistors (controllable switches), and a really easy to read tutorial book to take you step by step from blinking an LED to controlling stepper motors.
$100 can be a bit much so if you don't care about looks as much/want to buy sensors as you go you can buy the Arduino (https://www.sparkfun.com/products/11021), Breadboard (http://www.amazon.com/BB400-Solderless-Plug-BreadBoard-tie-points/dp/B0040Z1ERO), a refill kit (https://www.sparkfun.com/products/13110), and a few transistors (https://www.sparkfun.com/products/521) for about $50 bucks and then all of SparkFun's tutorials are online (https://learn.sparkfun.com/tutorials/sik-experiment-guide-for-arduino---v32/experiment-1-blinking-an-led). These include all the code, how to use the sensors/wiring, and anything you want.
Good luck!
How many kids per session? Same kids do all 6 sessions?
I really love the German examples given for introduction. 9V battery, LEDS to see what happened.
You could use $2.10 solderless breadboards Issue I had was my surplus resistors had oxide on the leads, so you had to hold the resistor and spin it while pressing the lead against a pencil eraser to clean that layer of oxide off.
