The plywood product I used was 1/2x2x4 G1S, $37 ea before tax in Ontario in summer of 2022. For the project infrastructure, four 1" x 4" x 8' knotty pine planks would be price competitive and less work to waterproof, but less convenient to transport....
In the arduino code set your WiFi credentials char wifissid[] = "ENTER YOUR WiFi SSID HERE"; char wifipass[] = "ENTER YOUR WiFi PASSWORD HERE"; Normally, the signal strength is displayed in dBm. But for a non techie person, the signal strength in terms...
Making the Yagi1) Use the dimension for the elements from the design I posted above to measure and cut the elements. 2mm fencing wire & some small wire cutters does the job, try to get the lengths as accurate as possible.2) Use a sharpie to draw a straight...
This picture is of my "indoor" seismometer, with its electronics in an antique wooden box next to it. It is networked and completely functional, but because of its noisy indoor location, it is not useful for any serious seismology. It is never quiet,...
Flash the Arduino with the following sketch. This is also included as a file attached to the project. int last_level = 0; bool last_state = false; bool stable = false; int count = 0; const int cutoffs[198] = {/* 1*/ 833, 831, /* 2*/ 825, 823, /* 3*/...
Drill two holes, almost all the way through, two blocks of something the same size as the outer diameter of your roller blade bearings. It's a common size like 3/4 or 7/8in. Make them identical. For the hole you are after, you need a nut on the threaded...
Cannon code- #include "Servo.h" // include the servo library Servo armServo; // servo to raise the arm Servo cannonServo; // servo to recoil cannon // these constants won't change: const int triggerSensor = 1; // the sensor is connected to analog pin...
By using "Dremel circle cutter" cut two plastic circles177mm Diameter for pressure sensitive surface155mm Diameter for bottom baseIn my case I build my own circle cuttercheck video for details https://www.youtube.com/watch?v=D8kZFAhsS1g
Bend the pins on the header at a right angle. Drill 8 holes 1/16-inch (1.6mm) diameter in a line spaced 0.1-inch (2.54mm) on centers. Pass the pins through the holes with the header on the underside of the box.
Optional (see #6 too, option of hard or soft enclosure): Use a 12" piece of 3" clear diameter heat shrink tubing to cover the board, the cut out the USB-mini connector with an X-acto knife, and mount rubber bumpers such as Digikey part # SJ5748-0-ND...
Mirror Mounts0Mirror Mounts… where to begin, in many ways… these are the make or break it for this project. These have some very high tolerances and requirments. Especially considering I am doing this all by hand, after all, the goal of this project...
To hold the iPhone into the foam block, I routed a pocket the same size as theiPhone into the top of the block. Normally, I would have routed the holea little bit larger than the phone to ensure that it would fit, but by making the pocket the same size,...
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...
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...
