Pressure Cooker Vacuum Chamber
Instructions from Pressure Cooker Vacuum Chamber
Step 6: Vacuum time Well, we're finally here. It's time to turn on the vacuum pump, and run for cover. Maybe.Before we actually flip the switch, a few words of caution from our sponsor.First, be sure to read the instructions that came with your pump....

Sugarcube - a tactile music controller
Instructions from Sugarcube - a tactile music controller
Solder LEDs and diodes to sparkfun board, be mindful of their orientation.Thread the leads of 16 LEDs (5mm or 3mm are fine, I used 5mm) through LED holes in the Sparkfun PCB. These boards are compatible with 4-lead RGB LEDs, so there are four available...

Instructions from Sugarcube - a tactile music controller
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...

Instructions from Sugarcube - a tactile music controller
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...

Instructions from Sugarcube - a tactile music controller
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...

Instructions from Sugarcube - a tactile music controller
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...

Guided Rocket
Instructions from Guided Rocket
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)

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...

ATX power supply conversion for bench usage
Instructions from ATX power supply conversion for bench usage
Add terminal strips and mounting helpers to the base plate:I later replaced the terminal strips shown in the picture (6 mm²) with bigger ones (10 mm²) because they were simply easier to work with.The PVC tubes are used to hold cable ties. Use...

ATX power supply conversion for bench usage
Instructions from ATX power supply conversion for bench usage
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...

Modular cartesian machines
Instructions from Modular cartesian machines
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.

Modular cartesian machines
Instructions from Modular cartesian machines
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...

Modular cartesian machines
Instructions from Modular cartesian machines
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...
