Step-by-step run through of how a Joule Thief circuit works. Includes how all the parts, the 1.5 volt AA battery, the resistor, the transistor and the ferrite core with its two coils of wire work together to build up energy in a magnetic field which then collapses to produce enough voltage and current to light an LED (Light Emitting Diode.) This includes explanations of the feedback that rapidly opens the transistor between base and emitter to open up the emitter to collector too. And also the feedback that slams the transistor shut again.

Before showing the making of my 18650 Box Mod, I cover the schematic and how the personal vaporizer works. I also show the AwesomeVapor Ego, a great PV that I bought from awesomevapor.com — great folks, excellent service, I highly recommend them, and their Ego. All the parts used in my mod came from: Radio Shack – the box, pushbutton, and battery holder (that I cut up for piece parts) – I could have gotten these from madvapes but happened to stop by my local Radio Shack for the fun of it. madvapes.com – the LED, resistor, battery-atomizer connector batteryjunction.com – They have a deal on 2 protected 2400maH 18650 batteries and charger. Wow! Target – Hot glue Harbor Freight – JB stick Epoxy putty Be extremely careful working with lithium ion batteries. ALWAYS use a PROTECTED Lithium Ion battery so that it will not overcharge or under-volt because they will explode and burn. Recharge these batteries outside on concrete under constant supervision in case they explode and burn while recharging. Unplug the charger and remove the battery(ies) as soon as charging is complete. Please do NOT attempt to make a pv e-cig mod unless you are an experienced electronic technician or a well-seasoned electrical-mechanical engineer. Each solder connection is critical, make it mechanical and then solder. Always remember, exploding lithium ion batteries can burn down your house and/or kill you and the ones you love!!!

What Makes Hitachi Impact Drills Works Faster
Professional service from plumbers, electrician, mechanics, and carpentry, clients always demand quick and fast service. To meet the demand of the clients, having a reliable power tool plays a bigger part. With a committed passion for innovation and development for power tools, Hitachi focused in taking the step of improving their power tool to perform faster with high durability. The new range of brush less motors guaranteed increase power that manages to do greater workload capacity than the conventional brush motor gives.
The brush less motor operation reduces electrical losses and improves longer running time. It saves you with the approximate 23 percent power unlike the brush motor easily losses its power that happens between the carbon brushes and commutator. This occurrence requires maintenance. With the brush less motor, there is no need to do maintenance for the motor is designed to operate in longer life span resulting 1.3 times more output that drills down both screws and holes harder and faster.
The cordless impact drill with brush less motor is operated by the Lithium-Ion batteries.
Making it last longer, it has the multiple protection circuit that protects your batteries from over use, over heat, over charge, and over discharge. Providing power with convenience, the ergonomics is maintained with its lighter weight, smaller size and compact. It also has the Electronic Control feature that allows you to choose multiple speeds to make accurate drills suited the material you are working. The electronic switch adds battery running time with the conserve energy. You can select between continuous impact mode and single impact mode for greater convenience.
Here are the upgraded range of brush less tools: DS14DBL – 14.4v Driver Drill, DS18DBL – 18v Driver Drill, DV18DBL – 18v Impact (Hammer) Driver Drill, WH14DBDL – 14.4v Impact Driver, WR14DBDL – 14.4v Impact Wrench, WH18DBDL – 18v Impact Driver, WR18DBDL – 18v Impact Wrench and the DV14DBL – 14.4v Impact (Hammer) Driver Drill.
Upgrade your cordless drill with the improved performance and faster Hitachi impact driver. See full details at sydneytools.com.au. Don’t miss to catch the latest promo this holiday season.
