Light-Up Spinning Top with Motion Sensor (OT5817) – user manual

View product

This user manual explains how to solder and build the OT5817 Light-Up Spinning Top with motion sensor yourself. You will need a soldering iron, solder and a pair of wire cutters for this.

Circuit diagram

The components must be placed in the exact positions shown in the table on the back of this manual.

WARNING: The LEDs and transistors must be placed in the correct direction (polarity), otherwise they will not work!

Also make sure you place the correct resistors in the correct positions. There are 2 types of resistors in this kit. The 1K Ohm resistor with the colors Brown, Black, Red, Gold and the 1M Ohm resistor with the colors Brown, Black, Green, Gold. Resistors are not polarized, so direction does not matter. There is no + or -.

1K Ohm resistor color code — 1K Ω resistor with color code Brown, Black, Red, Gold

1M Ohm resistor color code — 1M Ω resistor with color code Brown, Black, Green, Gold

Assembly

Solder all components onto the circuit board. Pay attention to the resistors, as they are different. The outer 2 are 1M Ohm (Brown/Black/Green) and the inner 4 are 1K Ohm (Brown/Black/Red). Direction does not matter.
LEDs are diodes, so current can only flow in one direction. The + and – are therefore very important. You can identify the + side of an LED by the longer leg. On the circuit board, the + is the back of the arrow.
The black transistors are shaped like a half circle when viewed from above. Make sure you place them the same way in Q1 and Q2. The brown capacitors next to them on C1 and C2 can be fitted in either direction.
Do not place the vibration sensor right against the circuit board. After soldering, it must be bent so that it lies flat. Now only place the battery holders and your spinning top is technically complete.
A gold-colored rod is included to make the top spin, into which the screw can be fitted. Place the circuit board between the rod and the screw and the nut. The screw is the point on which the top balances, and the gold-colored rod is used to turn it.
Insert the batteries (+ facing up = flat side) and the LEDs will light up when the top spins.

Enjoy!
