Tell us about yourself!
Plywood is a horrible and dangerous choice for a cutting board for several reasons: toxic glues and woods, (unless you're absolutely sure which glues were used, where the lumber came from, and where the panel was assembled... and unless you make your own plywood, you'll never know) low-quality/soft wood that splinters and chips easily, unsafe gaps for bacteria to get into, and it likes to absorb water. These are some of the reasons you never see plywood used in kitchen utensils.Walnut and Linseed oils are really bad choices for cutting boards; they go rancid.Your pictures show you using Titebond II which is for INDIRECT food contact only. In other words, it's not food-safe.Sorry, but nobody should ever make this.
HOW I BUILT a SHADOW BOX BOOKCASE
The video is not worthless, watch and listen. Nowhere does he say to bend both of the leads at the same time. Bend the longer lead (+/anode). Place the LED in the hole/jig with the short lead (-/cathode) straight up. Repeat. NOW bend the cathode so it makes contact with the LED next to it and solder. Repeat. It's clearly explained at 2:45
How did you hide/cover the dots on the backside?
So how many volts does this put out?
