MiniVol is my effort at a very simple volume control board based on the excellent TI PGA2320 volume control IC, which offers impressive specs and can operate over a range of -95. The circuit uses a serial-in-parallel out shift register, 74HC595 for receiving serial data from uController board. Invented by the French physician Gaston Plante in 1859, lead acid batteries were the first rechargeable batteries for commercial use. Lead acid batteries should be charged in three stages, which are [1] constant-current charge, [2] topping charge and [3] float charge. The battery is fully charged when the current drops to a pre-determined level or levels out in stage 2.
During the constant-current charge, the battery charges to 70 percent in 5–8 hours; the remaining 30 percent is filled with the slower topping charge that lasts another 7–10 hours.
The switch from Stage 1 to 2 occurs seamlessly and happens when the battery reaches the set voltage limit. Once fully charged through saturation, the battery should not dwell at the topping voltage for more than 48 hours and must be reduced to the float voltage level. Here is a lead acid battery charger circuit using IC LM317.The IC here provides the correct charging voltage for the battery. Build your own Accurate LC Meter (Capacitance Inductance Meter) and start making your own coils and inductors. 1Hz - 2MHz XR2206 Function Generator produces high quality sine, square and triangle waveforms of high-stability and accuracy.

How to Find a Brand Name Wholesale Clothing DistributorFinding a brand name wholesale clothing distributor is not an easy task especially when there are many distributors to choose from. See example of U5 in the schematic, SER is for data input, SRCLK is shift clock and RCLK is Latch clock.
In spite of the fact that it is one of the oldest types of batteries, lead acid batteries continue to be in wide use today, for various reasons. The engineers argued that the term “sealed lead acid” is a misnomer because no lead acid battery can be totally sealed. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries. The constant-current charge applies the bulk of the charge and takes up roughly half of the required charge time; the topping charge continues at a lower charge current and provides saturation, and the float charge compensates for the loss caused by self-discharge. The topping charge is essential for the well-being of the battery and can be compared to a little rest after a good meal.
The current begins to drop as the battery starts to saturate, and full charge is reached when the current decreases to the three percent level of the rated current.
Since collector of Q1 is connected to adjust pin of IC LM317 the voltage at the output of of LM 317 increases. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.

Lead acid batteries are very dependable and much cheaper with respect to the cost-per-watt.
This is true and battery designers added a valve to control venting of gases during stressful charge and rapid discharge. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 10 hours or less; however, the topping charge may not be complete. If deprived, the battery will eventually lose the ability to accept a full charge and the performance will decrease due to sulfation. A battery with high leakage may never attain this low saturation current, and a plateau timer takes over to initialize the charge termination. Charging beyond what the battery can take turns the redundant energy into heat and the battery begins to gas. This charging circuit is designed based on this fact.The charging current for the battery is controlled by Q1,R1,R4 and R5. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground. Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time.
