Painting eggs made easy! You just have to press the button and hold various felt-tip pens on the rotating egg.TOOLS Wire stripper soldering iron solder scissors Shrink tubing (alternative: insulating tape) Lighter (for heat shrink tubing) Note: If you don't have a soldering iron, your machine will work too. But solder connections hold much better! 1 Cut the connector from the fan cable and pull the two cables apart so that you have a red and a black strand. Use a wire stripper to pull about 1 cm of the cable sheath from the two cable ends. Do the same with the ends of the battery clip to get about 1 cm of open cable end. 2nd Cut three 1.5 cm long pieces from a thin shrink tube and put one piece each on the red cable of the fan and one on the red cable of the battery clip. We will need the third piece later. 3rd Now it gets fiddly! Insert one of the two red cables (from the fan and battery clip) into an eyelet on the slide switch and fold the end of the cable so that it can no longer slip out of the eyelet. Tip: If your switch - like ours - has three legs (contacts), you use the middle one in any case, and then one of the two outer legs. 4th Finally, twist the two black cable ends by twisting them tightly together. Check then , if your cable connections hold well. To do this, simply pull the cables slightly. 5 Now put the battery clip on the battery and test the switch: You should now be able to switch the fan on and off with the switch. Tip: It's best to unplug the battery after the test to avoid a short circuit. Because be careful: If the black and red cables touch, there is a short circuit, the battery gets very hot and, above all, it has no juice afterwards!
