Note that some of the components are static sensitive, so you should avoid sources of static

electricity while you are handling them. We recommend that you assemble the Eggtimer TRS

on a wood or metal surface unless you are fortunate enough to have a high-temperature anti-

static mat (don’t buy one just to build the Eggtimer TRS, however!) Avoid putting it on plastic

surfaces that generate static, and preferably put it together in a room that’s not carpeted. That

being said, it’s very unlikely that you will zap any of the components in the Eggtimer TRS

with static electricity, but consider yourself notified of the possibility…

Also note that some of the components are polarized, i.e. it matters which way you put them in.

If you solder one of these components in backwards, the effect will range from something not

lighting up (LEDs) to nothing at all working. It is CRITICAL that you test-fit the parts before

you solder, and that you make SURE that you have them pointed the right direction before

soldering. Like the old adage says, “Measure twice, cut once.” If you solder a part onto the

board incorrectly, it can be a minor pain to remove if it only has two pins, or it can be virtually

impossible for something with a lot of pins. The Eggtimer TRS Limited Warranty does not

cover incorrect assembly, so if you mess up badly enough you may end up having to get

another kit and starting over; neither of us want that.

There are several different resistor values, so make sure you get the right ones in the right

place. They are marked on the boards, but once again you need to make SURE that you have

them in the right place before soldering. Unsoldering parts on a small circuit board like the

Eggtimer TRS isn’t a lot of fun, even if you have a vacuum desoldering tool. Trust us, we’ve

been there before…
