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.

12V Lead Acid Battery Charger(Homemade)



I took a MOT and carefully stripped out the 2000V Secondary and replaced it with a low voltage high current winding of 18-20T or 12ga wire. New fully rectified DC output is 15.8VDC. An electrolytic capacitor of 1500uf was also added for smoothing purposes(Not much smoothing is required for charging lead acid batteries). Also includes a voltage monitoring circuit which allows you to know when the voltage of the battery being charged has reached completion. A green LED will be brightly illuminated to let you know to unplug the charger.

Schematic Here:

The circuit in the schematic above will connect to this automatic charging cut-off circuit, then to the battery to be charged:

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!

Cut-Off Circuit For 12V Lead Acid Battery Charging



If you are looking for a simple but effective Lead Acid battery charger cut-off circuit, then look no further. You can use this circuit in conjunction with any battery charger(except capacitive types) which do not have an automatic shut-off once the battery voltage has climbed to 14.2V(You can adjust this value with the zeners). You can modify the circuit to charge 6V lead acid batteries instead of 12V as shown in this video. Just replace the relay coil with a 6V type, use a lower voltage power supply (8-12VDC Open Circuit), replace the 12v zener leading to the base of the NPN with a 6V or 6.2V, along with the same (2) 1n4001’s in series, replace the 12V zener to the relay coil with a 6/6.2V zener, and cut the value of the LED resistor in half.

Jazz Up Your Game With the Latest Gaming Headset

Using a headset has become a necessity due to multiple reasons that are propelled by modern day’s lifestyle. One among such reasons that have made the use of wireless headset more popular, is the online games. New games are created to generate a live-action experience for the gamer, thus making the use of headset mandatory. Keeping this in view, different and innovative headset models have been introduced to the market. One such model, which is gaining popularity, is the Wireless Gaming Headset. These headsets are specially designed for gamers and are equipped with every feature that is demanded by various games. All the models under this product category have certain advantages over the wired headsets. Here, you can find a few to ponder upon.

• These headsets are portable and can be carried easily and can also be used for multiple devices.

• The technology used for transmission in case of wireless headsets are quite advanced and can receive signals even from Bluetooth.

• These Gaming Headsets boasts of a better life-span if standard batteries are used and properly charged.

• Besides regular use, these headsets are mainly developed for gamers. This is the reason why these gaming headsets are much more popular in the area of VR games.

• The quality of the headsets are much higher and the voice is crystal clear. Besides this, they free you from the hassle of wired headsets and enable you to multitask.

Now, let us explore the basic features of the top and best models in the market right now:

• Mics: All the Wireless Gaming Headsets have either an omnidirectional or unidirectional mic to provide perfect gaming experience. However, many prefer to have the unidirectional mic rather than an Omnidirectional mic as latter would grab all the sounds of the axis and create a nonsense.

• Compatibility: While buying a particular company headset, check out the compatibility of the headset with that of the device. Majority of the headsets are designed to support almost all the devices, however, checking on doesn’t harm anyone.

• Battery life: Almost all the gaming Headsets available right now in the market have a lifespan ranging from 10-22 hours. Check with the maximum time of your usage and select a model that fits your need in terms of usage and budget.

Since a long time, these headsets are facing challenges of price, latency and battery life and newer models are out every now and then.
