Hot-Rodding A Bluetooth Adapter

carbolic writes "Remember the Bluetooth records where we 'modded an adapter' and connected to a cell phone first from 1 kilometer, then from 1 mile away? Popular Science has the hack in the November issue (or online now) with instructions. Additional step-by-step is laid out here for USB, and and here for PCMCIA.

If you start clean, all that is left is fine tuning your heat bridge skills and using the correct amount of solder. You can get a good joint with practice. All oxidation and oils must be removed from all things for the rest of the process to work. There are finer tips and practices like component mounting distance from board depending on wattage of component, proper lead bending radius for stress removal, tinning of wires (prevent solder from flowing under the insulation), through distance (how far a component lead should stick out the other side etc..),although they are very good to adhere too, those things only come into play if your work had to meet specific requirements or be inspected to be certified. That is another level altogether.

      Lint free wipes with alcohol for debris and oil removeal around the pads and solder

Simply put, they don't tolerate it well. So that iron (I've seen the ad, too) is more than a joke. It's downright dangerous when it comes to IC work. One company I worked for (we made pacemakers) only used ESD-safe butane irons for rework. Completely eliminated the chance of an electric iron doing damage.

      As for Radio shack, they make (well, someone makes it for them) a decent 23-watt pencil iron for about 10 bucks. Get a 3 pack of different sized tips and some 60/40 solder(or they have thinner 60/38/2 (silver is the 2%), which is GREAT for a lot of delicate work), some 18 or 22 gauge wire, a sponge, some desoldering wick, and a cheap stand. You'll be out about 25 bucks, but it'll pay for itself over time.

      As for practice....soldering is not something learned overnight. The iron is a lot like firearms: respect what it can do to you, but don't be scared of it. Yes, you will burn the shit out of yourself at least 20 times (hint: if the soldering iron rolls off of the table, DON'T GRAB FOR IT!. You WILL grab the wrong end. Every time. It's a law of physics). I found playing with old ISA cards is a great place to start learning. They have lots of big components to practice both soldering and de-soldering, and you can use the wire you bought to solder on to pins of components for practice. Give a half-hour here and there, and soon enough you'll know enough not to be dangerous. Not to say this is the hardest thing in the world, but good soldering is a skill that takes a little finesse.

      Yes, you can go get a fancy Weller or Metcal workstation, but you never loose the need for a good standard pencil. Still have mine, after all these years.
