Sugarcube - a tactile music controller
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...

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...

Seeing the invisible
Instructions from Seeing the invisible
1) Make the point source. The easiest way of getting a point source is to use a clear LED. These are the ones where you can see the silicon die within the LED. To make a point source, simply remove the dome from the LED and try to remove as much plastic...

Drill 3mm holes in the necessary spotsScrews ready for mountingOuter ring will be attached to this pivot

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)

Guided Rocket
Instructions from Guided Rocket
Buy and place metal gear servos in the main frame and epoxy the tabs. Next attach 1 rod to each ring, and to each servo so that the rotation of the servo changes the angle of the ring

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...

Craig-o-Matic
Instructions from Craig-o-Matic
I found the Adafruit small mint tin perf board to be ideal to mount two DC barrel connectors and the Arduino pro mini. I mounted it to the ammo box using some 1/2 " standoffs.

TS9 to F connector
Instructions from TS9 to F connector
Cut off a short section of RG-59 cable. Strip both ends so you are left with the center conductor, an inch of exposed wire on one end, and 3/8in on the other. Rotate it between your fingers and sand down the remaining foam insulation so it...

Using a 1/4 in brad point drill bit in your drill press, drill through the reflector holes. These are the ones closest to the end. Make sure you get this one perfect as it will control the rest.Technically brad point drill bits are for wood,...

4G LTE Yagi antenna for ATT
Instructions from 4G LTE Yagi antenna for ATT
Drill the remaining element positions. Start the drill at each position, back off on pressure, and sight down the tube to the level. Rotate the tube until the level reads 'level', then clamp/hold it tightly and drill through the top. When you break through...

Instructions from 4G LTE Yagi antenna for ATT
Cut your elements to length, adding 1 mm, starting with the longest ones. As I don't own a band saw, I found my scroll saw worked well for this.Sand each until it hits the target length, squaring up the ends. If you over-shoot, cut it down...

4G LTE Yagi antenna for ATT
Instructions from 4G LTE Yagi antenna for ATT
Mark each element from both ends, to the 'insert to' depth. Line them all up so they go smallest to largest.Start with the largest, put it in the first director hole, and center it in the tubing.Lay it flat, so the director is now horizontal, check your...
