My fiance and I are getting married in May. We decided on a literary theme, so lots of our books and old love letters will be on display. (We were long distance for 3 years so have written each other hundreds of letters and she is making her paper bouquet out of them.)
I want to build a wooden letterbox to be used during our ceremony in lieu of a unity candle or sand ceremony. I want us to write each other a letter every year and drop it into the box for us to open again on our next anniversary and read together. They have letter/wine boxes sold on Etsy but I want to make it myself. These versions usually have the couple nail the box shut with a hammer during the ceremony.
I have never done anthing like this, so I don't have any knowledge on how to do so, nor do I own any tools. It needs to be able to withstand the test of time as we will be opening and resealing it once a year for the rest of our lives. I need to know everything about how to make a wood box: what type of wood to get, how to cut it, how to construct, finish the wood, the closing mechanism, etc.

Hello /diy/, I've bought some IR LEDs, resistors and whatnot to build a TrackIR. Problem is, everything in google says that anode, which is the positive contact, should be smaller, and that the reflector and the bigger part of the LED is cathode and the negative contact. So I wired one up to test, and it didn't work at first, but it did when I reversed it. Can you shed some light? Are these some funky groovy LEDs that don't play by the rules?
Also the setup is:
power: 5.6v 800mA charger
diodes: IR 100mA
resistors: have a bunch of 8.2 and 2.0 ohm ones
