Step 1: FAQsHow does it work?The LED on the PCB lights up in a specific mode. When the motor rotates the circuit board, you can see the pattern - this is an example of the "visual persistence" effect.
Does it need batteries?yes. The kit comes with a lithium battery to power the SX, but you need to provide 2 AA batteries to power the motor. The board is designed so that you can also mount it on other rotating objects, such as bicycle wheels.Can it be placed on something other than the motor?
Yes, the board has a set of holes at both ends. By passing string or wire through the holes, the board can be tied to almost all objects. I've tied it to my bike. It looks cool.What are the modes?You can see examples of pre programmed modes in the video. Previous step. Arrows, animations and text characters are all possible.
Can I change the pattern?yes. You'll need an SX blitz programming key, but otherwise it's very simple. The last step of this directive has a link to the source code that you can modify.The rotary LED display is designed by microcontroled1204.

Step 3: preparation: ToolsThis is a good project for learning welding. There are many good instructions on how to weld (here is one).tool
You will need some tools to assemble the project;1 - soldering iron and solder. Lead solder is easier to use, while 15 to 40 watts of iron is OK. Conical or chisel tips work well.2 - embankment. The diagonal cutter is used to trim the excess lead on the component after welding down.
3 - battery. You will need two No. 5 batteries.If this is your first electronic project, Isuggest will start with a cheap soldering iron. Why? Because you can do electronic projects without spending a lot of money. If you like, you can upgrade to better equipment and hand over the No. 1 iron to others who are just starting. Ioffer's Elenco kit includes a 25 Watt iron, bracket, wick and suction cup for $25 (as shown in the figure below). You can also buy a beautiful weller iron on Amazon for $15, including additional soldering iron head and solder (but no wick or solder suction cup).Step 4: manufacturing part 1
Eight identical resistors (brown red brown, 120 ohms) are located at r2-r9. First, add 2 of them to R8 and R9.Step 5: Manufacturing: Part 2,Then we will make a second set of resistors. Similarly, 120 ohms (brown red brown) at R5, R6 and R7. Insert, flip, weld and trim.
Once we enter the first two lines, we will perform the same operation on the last line (R2, R3 and R4). The same resistance is 120 ohms (brown red brown).Step 6: Make: Part 310K ohm resistance at R1. It is brown black orange, as shown in the figure.
Step 7: Make: Part 4Let's add LEDs. Note that LEDs are polarized. The longer wire enters the square hole (right side). Insert and fold its part so that the LED crosses the edge of the PCB. Weld it down and trim the excess wires.Perform the same operation for the other 7 LEDs. Make sure the polarity is correct - the longer lead always passes through the square hole.
Step 8: Make: Part 5After the LED is completed, let's continue the dip socket. Note that the notch of the slot is closer to the 10K ohm resistor (left in the photo).Step 9: Manufacturing: Part 6
Turn the board over and add a button battery base. The device is also polarized. Please note how it is inserted into the photo. The "tower" side of the support passes through the hole near the LED.The rack will accommodate one or two cr2016 batteries, or a single CR2032 battery. SX is not picky. It can run on any configuration.Step 10: Make: Part 7
Return to the top of the PCB, trim off the excess wires on the button battery base, and then put the SX into the dip socket. We're almost done the last step is to install the motor.Step 11: Manufacturing: Part 8In the photo below, you can see how I installed the motor. I used some extra wires (from resistors) to form a loop, and then passed the motor spindle through the loop. After this operation, I used a healthy solder to weld the spindle to the PCB and circuit.
You can choose where to connect the motor. If you connect it in the center, as shown in the photo, it will rotate quickly. It is recommended to connect it to the larger circumference of the edge of the PCB.You also don't have to fully connect the motor - you can use the holes on the PCB to connect it to almost any rotating equipment, such as bicycle wheels.Last step - connect the AA battery pack to the motor with 2 bayonets on the motor. The battery pack has red and black wires, but it doesn't matter which wire is connected to which terminal.
