Two 74HC595s (wired in parallel) will be driving all the LEDs in the project as well as providing power to all of the buttons. The 74HC595 is an 8 bit serial in parallel out shift register. I've written a detailed tutorial about multiplexing with the...
The 74HC595 can only do parallel output, so I used a 74HC165 to measure the state of the buttons via 4 current limiting resistors and send this information to the Arduino. More info about the chip can be found on its datasheet.The 74HC165 has the following...
I attached a 2 axis gyroscope and 3 axis accelerometer onto this project so that I could add some interesting control to the device. The 5 degrees of freedom board from Sparkfun outputs data from its gyroscope and accelerometer as analog voltages. I...
All schematics for this project are shown above. All the Arduino pin connections are listed below:Analog0 - Gyroscope Y (Y4.5) 1 - Potentiometer 1 2 - Gyroscope X (X4.5)3 - Accelerometer Y (YAcc) 4 - Accelerometer X (XAcc) 5 - Potentiometer 2Digital0...
Test the fitting for the outer ring to the main frame and sand if needed, it should be a solid fit. Do the same for the inner ring, it should look like the picture below. (1 ring should turn in the x axis and the other in the y)
Jacket Wiring, LED Setup, and Light Pipe Assembly.I never took pictures of this process with the first prototype so I need to complete the second prototype and take pictures to use as visual aides along the way, I should have them up in another week...
Optional 3D Printed Jacket Module CaseDownload the Base and Top to the case and print them on your favorite RepRap OpenSource 3D Printer. It should come out looking similar to this(colors may vary ;) ):The headphone jack hole may need to be cleaned up...
Prepare the adapters and connect them to the terminal stripsThis part is important and tricky, and it took me three attempts to get this right. Here's the rules: Any high-current line must be a twin line that starts as a twin at the power supply's PCB...
Here, the basic module modified to be used as axis X of the plotter. It is exactly the same structure only the size of the rods has been modified and we have exactly those that we needed and keeping strictly background's rules.
We have two modules suitably resized to be used as axi X (red) and axis Y (blue). We needed this two similar structures, and placed it in orthogonal form, that is, his axes displaced 90 degrees one respect the other. In this image we see how we must...
This green piece join the two structures. With the hole for the linear bearing in the bottom part and the space for the corner pieces in the upper part. With four of this green pieces and four linear bearing we can join the two structures and can move...
Mounting the EngineTools: 5/16" Wrenches and SocketsA) Prepare the Engine1) Check the wiring and redo the connectors2) Remove the excess choke hardware3) Remove the excess throttle hardwareB) Bolt the Engine to the FrameUsing (4) bolts, (4) lock washers...
Building the ExhaustTools: Chop Saw or Reciprocating Saw, Files, Welder, Torx (T40) bit, Socket Wrench, 1/4" and 7/16" socketsA) Cut the materialsUsing the chop saw or reciprocating saw, cut the 1" diameter U-Turn and the 135 Bend, as well as the 1 1/8"...
Required Components:The component list for this computer is fairly low as only a single IC is required: 1 x ATmega 1284P Microcontroller 1 x DIL 40 Pin 0.6" IC Holder 1 x 40 Pin Female Pin Header (to be cut down into smaller headers) 1 x 16 MHz Crystal...
Below is a list of build instruction logs that will instruct you on how to go all the way from sourcing your components to printing the parts, and constructing your very own raman spectrometer!To begin, you will need some tools.. Pretty much every...
