The canny designers of non-lethal weapons have taken a cue from marketing experts in a variety of fields, especially electronics, when developing products to fit the needs of today's safety-conscious citizens.



The servo motors are usually powered by batteries. This power source is then regulated to 5V (using voltage regulator). Amount of voltage depends on applications needed. 5V voltage is enough to drive torque to perform useful motions. Commonly, servo motors are powered by smaller batteries like Nickel Cadmium ('NiCd') or Nickel-Metal Hydride ('NiMh') or even the latest; Lithium Polymer ('LiPo').

If cell phones are more your speed, the Firestorm cell phone stun guns is the one for you. It only takes three 3-volt lithium batteries (available at Walmart for about $14.00) in order to deliver the 800,000 volt jolt. This petite model is particularly easy to carry and has built-in safety features you will appreciate. However, when encased in its holster and installed on your belt, it looks just like an ordinary cell phone. You could say the difference is subtle but stunning.

NEVER puncture the cell, ever! If a cell balloons cobalt mining copyright rapidly place it in a fire safe place immediately. If this happens and smoke and heat is coming from the LiPo get it clear of all other items and be prepared for flame to come out! If after many hours have passed (days) and the pack is still ballooned but have not combusted, discharge the pack slowly and dispose of it in a proper way.

Another thing to remember is not to store those batteries in the charger as well. This will draw energy away too, and cause your battery to die off sooner than you expect. Keep it away from high heat or extreme coldness. Heat tends to cause damage to your battery while exposing it to low temperatures over a period of time will draw its charging capacity.

A lithium drill is much lighter than a comparable drill of the same voltage. This allows you to use higher voltage tools with lighter weight. Remember, voltage equals power, mah equals the gas tank of the battery. So, if you are using a 12 volt now, a 18 volt or even a 36 volt lithium mines ontario drill will offer you much more power and still have the same run time of you 12 volt with close to the same weight.

You talked in the April edition of your newsletter about Pacific Asia China Energy (TSX: PCE) and stated that they overcame the obstacles to get a coalbed methane deal out in China.

The final thing I really enjoy about this Makita is the built-in L.E.D. light. If you're one that often drills in dark areas, this light is definitely something that comes in handy. All things considered, the Makita BDF452HW is a great cordless drill and I highly recommend checking it out.
