Excellent & Simple Battery Charger (Gel/Lead Acid/Li-Ion/+ more)



This circuit has been in use for 24 hours a day over the past 4-6 months. It operates perfectly. I used this circuit to charge two 18650 Li-Ion batteries for my cordless vacuum cleaner. You can charge many different battery types with this circuit. If you charge (2) Li-Ion batteries in series as I did, be sure to affix a 3A/ 70-90 degree Celsius thermal fuse between both batteries using thermal heatsink compound and foil tape. The fuse will then be wired in series with the 2 batteries. Also set charger output voltage to 8.33V – 8.36V, and use a 1 ohm resistor in the circuit.

Apple MacBook Air MQD32LL/A Overview: An Affordable PC With Long-Lasting Battery and Thunderbolt 2

One of the most important factors of any laptop is its battery life. The longer a battery can last on a single charge, the better. Most people can agree that twelve hours of battery life is pretty impressive, and that’s exactly what you will get with the Apple MacBook Air MQD32LL/A. Not only does it come equipped with a good built-in battery (lithium polymer 54-watt per hour), it also comes with an Intel-Core, dual-core architecture.

Space is saved in the design thanks to PCi-e based SSD (128GB) storage solution. There are no moving parts, therefore no need for the additional space. As a result, the MacBook Air has a streamlined look ad weighs under 3 pounds.

As mentioned above, the CPU is a dual-core Intel Core i5 unit (1.8GHz) that is designed to be ultra-efficient, yet powerful. It uses less power, but still manages to deliver high performance. You’ll get additional performance from the integrated HD graphics (6000) – especially when doing graphics-intensive tasks.

The MQD32LL/A supports dual-band Wi-Fi (802.11 ac). When connected to a base station, including AirPort Time Capsule and AirPort Extreme, the wireless performance of the PC is up to three times faster than standard 802.11 n technology. With the included Bluetooth technology, you can connect your MacBook to other Bluetooth-enabled devices.

For devices that do require an actual physical connection, Thunderbolt 2 ports boost the speed of file transfers. There are two USB 3.0 also equipped. Backwards-compatibility means that you can connect older USB 2.0 devices to the laptop, such as earlier versions of the iPad or iPhone.

Apple MacBook Air MQD32LL/A Display and Camera

Other important features to include in this Apple MacBook Air MQD32LL/A review are the display, camera, and audio. The display is a 13.3-inch model with a screen resolution of 1440×900. It only measures.19-inches in thickness. LED-backlighting makes the colors vibrant and bright, from edge to edge. The FaceTime HD camera lets you see friends, family and acquaintances in a widescreen format during video chat. During the chat, the dual microphone setup reduces background noise. The Dictation application also helps to mute background noise and adjusts automatically to your voice.

The multi-touch trackpad allows for a variety of gestures such as a three-finger swipe and four-finger pinch. Responses are always realistic and smooth. Apple still managed to equip this slim MacBook with a full-sized keyboard featuring LED-backlighting, which detects changes in the lighting condition and adjusts the brightness on both the keyboard and display automatically.

Needless to say, the Apple MacBook Air MQD32LL/A is an excellent laptop that comes with everything you need for productivity and mobility.

9V Alkaline Battery Charging Circuit(Also 1.5v Cells)



Learn how to make a good alkaline battery charger which is NOT likely to cause the batteries to leak or bulge, and will charge them properly. Though alkaline batteries are not intended to be recharged, they do seem to recharge well using this circuit. I put together this circuit from information obtained from the web page below. The circuit shown in the video was designed for 9V batteries, but you can also charge 1.5V (AA/AAA/AAAA)batteries by lowering the power supply voltage. The batteries are charged using low current DC pulses.

Bedini SSG Battery Charger/Desulfator



This circuit uses a 12v battery to charge other 12v batteries to a higher voltage. According to John Bedini, you are getting more out of the circuit than you put into it(Which I have not proven). The high voltage that is created to charge the 12v battery is created by the back EMF from the coil.

Inductive Battery Charging Circuit (NiMH/NiCd)



Learn how to make a simple inductive battery charger for your NiMH/NiCd rechargeable batteries(2 to 4). The circuit in the video is for charging (2) batteries in series. This circuit operates in a very similar way as an ultrasonic toothbrush charger. The charging rate is slow(25-30mA), which can be made higher if desired, but it does charge well. The toothbrush charger uses a PWM IC to produce the high frequency pulses (75khz) into the primary winding with feedback to adjust the output under load, and this circuit uses a 555 IC to produce 42-46khz pulses into the primary winding to simplify the circuit. The transformerless power supply shown in this video is designed to power the exact circuit shown in this video. If you modify the primary winding and the circuit draws more current, then you will have to modify the transformerless power supply to deliver more current. You can also power the circuit using a very small 12V transformer. Don’t be afraid to experiment with different coils/windings!

Homemade 6V / 2.5 Amp Power Supply/Battery Charger



If your looking for a HIGHLY efficient (6VDC 2.5A / 6VAC 3.0A) power supply or 6V lead acid battery charger, then look no further. This power supply/charger is made using a 120V (MOT) microwave oven transformer, by performing the modifications shown in this video. 120V transformer current at idle(NO LOAD) only draws 30mA, and using a full 2.5A load, 200mA. NO heating issues of the core whatsoever. As usual, always be very careful when working with 120VAC/240VAC projects!
