  • Constructing the NAND gates.

  • First, construct 60 NAND gates, following the given schematic and picture. I did this by cutting out 6x6 hole pieces of prototyping pcb board, and soldering all the components in according to the gate schematic. I then connected MALE pin connectors...
  • QubeCast Max

  • TestTesting can be done a variety of ways. Apart from the usual power checks, you'll need to load some basic test code into your MCU so it can tell the radio to transmit something.You can use an SDR dongle to look at the waterfall plot of the test frequency....
  • PROFIT!

  • Solder the 2x10 pin female header to the P30 header mount, it should be labelled.Clean the board with flux cleaner and a brush.  Place the shield top plate on the frame.Plug it in, and test with SDR# if on Windows, GQRX if you're using linux! Enjoy...
  • Flash the image to the SD card

  • Download the latest image and flash it to the SD card using Raspberry Pi Imager. Either choose EU version or US version for your location. I chose US but I don't know what other than the wifi frequencies are actually different. The SDR Radios I purchased...

  • 1: The Robotics KitKit ContentsWe have provided the contents of our kit below so that inventors all over the world can make their own DIY version of this simple robot kit. Electrical Stuff1 x Rectangular Arduino Uno compatible board 1 x A-B USB Cable....
  • Attach the cables

  • Cables can now be run around the edges of the case, in the recessed runs provided.The USB-C power port should be connected to the PiJuice.Connect the cables for both the keyboard and trackpad to a 2-port USB hub, and connect the hub to the single-port...
  • Perform an experiment

  • Once a suitable location has been identified, set up the system to display the receiver spectrogram as before. Then, insert a sample into the coil. Tap water is an obvious sample choice, but most common liquids will also exhibit a hydrogen peak. Next,...
  • Pi0Plane

  • Step 10: Testing the center of gravity.The last thing we have to do is some tests to know if it is well balanced. In the first test, we are going to test the pitch by using the 2 circles that we can see under the wings of the plane. We are going to put...
  • An additional test

  • This stage is optional but can be useful for troubleshooting. Once the coil is tuned, we can artificially test whether both the system and local noise will allow for the detection of a signal. This test can also be used to check an unverified amplifier...
