This post comes from Michael Richards, the designer of the Cossack light hat which you can make at home using 12V DC LED strips.
As those of you who have made your own transcranial light device know only too well, the back of 12V DC LED strips comes with glue on the back, covered by a white peel-off tape.
You can see in the Cossack photo on the left that the white tape has been left on the LED strip.
If you are planning to re-use 12V DC LED strip then you will find that the glue on the back of the LED strip can become quite a pest.
Michael has discovered a very neat way of removing the glue – use talcum powder. Sprinkle talc over the glue-covered back of the LED strip and gently rub it in. The glue will have met its match and will be much easier to use.
