I realized that this traditional pointer needn't be used only for reading the Torah. A pointer could be useful for reading secular books, or even books of another religion. I find that a pointer is especially useful when reading something technical, because it is very hard to concentrate on technical text, and sometimes the words seem to move around and rearrange themselves, or leave the page altogether at their own accord!
Also, my Secular Yad extends in length, so that it could be used as a more general pointer. It is very entertaining to watch others as you randomly pull a pointer with a tiny hand on the end, out of your pocket, and start pointing at things in the book the person across the table is reading.
Here are some examples of Jewish Yads:
Step 1: Get Supplies
Two male pins from a power connector
Two terminals (like the ones in the pictures)
A telescoping antenna from a radio
A silver jump ring
About a foot of chain
Dremel and diamond cut off disk
30 watt soldering iron
30 gauge enameled wire
