^ Double-sided foam tape is a quick-and-dirty method of attaching parts. The tape works ideally in securing circuit boards to enclosures or making sure that loosely fitting components remain in place. You can cut the foam tape to almost any size that you need, and you can stack layers if you need to fill a large gap. Be sure that you get the tape and the mating surfaces dry and free of dirt before applying the tape.

drying time of only about 30 seconds. The glues are waterproof and gap-sealing. You apply the glue at about 250 to 350 degrees ó hot enough to burn skin (so be careful!), but not hot enough to melt solder or damage most electronic components.

Setting Up Your Electronics Lab
Where you put your workshop is just as important as the projects you make and the tools you use. Just as in real estate, the guiding word for electronics work is location, location, location. By staking out a comfortable spot in your house or apartment, youíll be better organized and enjoy your electronics experiments much more. Thereís nothing worse than working with a messy workbench in dim lighting while breathing stale air.
The top ingredients for a great lab

Chapter 3: Outfitting Your Electronics Bench
Ample electrical outlets, with at least 15 amp service ^ Tools and toolboxes on nearby shelves or racks ^ A comfortable, dry climate ^ A solid, flat work surface ^ Peace and quiet
The ideal workspace wonít get disturbed if you have to leave it for hours or days. Also, the worktable should be off-limits or inaccessible to young children. Curious kids and electronics donít mix!
So where in your house can you find an electronics haven, and how should you set it up to work best for your projects? The following sections give you a hand in figuring this stuff out.
Picking a perfect place to practice electronics
Before setting up shop, consider the best place in your house for building your projects. The garage is an ideal setting because it gives you the freedom to solder, hammer, and etch without having to worry about soiling the new carpet. You donít need much space; about 3 by 4 feet ought to do it. You can set aside an area for your electronics in the garage and still park the car (assuming that you donít already have that space clogged with bikes, lawn-mowers, old toys, and who knows what else).
You can use a room in the house if you donít have or canít get into your garage, but only if that room conforms to some basic requirements. When working in a carpeted room, you may want to spread another material or some protective cover over the floor to prevent static electricity ó for example, use an anti-static mat. You can read more about anti-static safety measures in Chapter 2.
Putting something down to cover the floor gives you a benefit besides reducing static electricity: When the floor cover fills with solder bits and little pieces of wire and component leads, you can take the floor covering outside, beat it with a broom, and put it back as good as new. (The cover is as good as new; the broom may be a little the worse for wear.)
A bedroom, den, or family room can be an acceptable location for your electronics lab, but try to clear away a corner or section of the room for the dedicated electronics hacking. Odds are, you need to leave projects overnight or for even longer periods of time from time to time, and your work needs to stay undisturbed.

If your work area is in a main area of the house, you may want (or need) to hide it when youíre not experimenting. You can make quite a mess working with electronics, especially if youíre in the middle of troubleshooting your latest project. A folding screen works wonders to hide your work area, especially if you have your work surface situated in the corner of a room.
If your work area is exposed to other family members be sure to keep intergrated circuits and other sharp parts off the floor ó theyíre painful when stepped on! Find ways to make the area off-limits to those with less knowledge about electronics safety. Kids are naturally curious about electronic gizmos, so if you have to, keep your projects, tools, and supplies out of reach on a shelf, or behind lockable doors.
If youíre working in a bedroom or den, you may want to consider placing the electronics bench in the closet. Close the closet doors, and no one knows that youíre building that intergalactic spaceship with built-in espresso maker.
