screwed onto the wheel nipple. When the bicycle moves, the cap begins to create a circle effect, which looks very cool at night when you ride a bicycle.
And so let's get started.
We will need:1. Ballpoint pen (tukzar 0.7 mm).
2.LED.
3. Three batteries "tablets".
4.Bicycle cap (from camera)
Instruments:
1. Soldering iron (solder, flux ...).
2. Glue gun.
3. Long nose pliers.
4. Electrical tape.
Let's get started.
From the end of the handle we measure 4 cm, and saw off. I did this with a heated knife.
That's what we got.
Next, take our LED and paste it inside this segment.
Then we take three batteries and put them in the same way as in the photo.
And fix it with electrical tape.We bend the legs of the LEDs in this way, the upper leg is "+", the lower one is "-".
We trick the negative contact of the battery.
Solder the negative contact of the LED to the negative from the battery.
Positive contact is also tricked and soldered wire.
This is what we should get.
Next, solder the wire to the positive leg of the LED. As a result, we get two wires, this design does not have a switch (in order to save space), so that all this works, we can only twist these two wires.
Before sticking the batteries with LEDs on the cap, you need to grind off the top of the cap so that it becomes flat.
Glue the cap to our design, and isolate the legs of the LEDs.
That's what happens if you close the contacts. And if there was a switch, it would take up a lot of space, and would not look beautiful. The luminous cap is ready for use.
