Homemade "B" Battery - I recently purchased a couple of old battery-powered
tube radios on eBay with the idea of using their cases to house a transistor radio
project...(electronic design added 08/08/08) |

IC Controlled Emergency Light with Charger - (electronic Circuit / Schematic
added 10/04) |
|
Lead Acid Battery Charger - Except for use as a normal Battery Charger, this
circuit is perfect to 'constant-charge' a 12-Volt Lead-Acid Battery, like the one
in your flight box, and keep it in optimum charged condition. This circuit
is not recommended for GELL-TYPE batteries since it draws to much current....

Lead Acid Battery Charger (LM317) - The above pictured schematic diagram is just a
standard constant current model with a added current limiter, consisting of Q1, R1,
and R4. The moment too much current is flowing biases Q1 and drops the output
voltage. The output voltage is: 1.2 x (P1+R2+R3)/R3 volt. Current limiting kicks
in when the current is about 0.6/R1 amp.....(Tony van Roon's schematic / circuit added

Lead Acid Battery Charger using the PIC14c000 - Microchip Application Note
Published 26-Aug-97 (app note added 2/06) |
|
Lead Acid Battery Charger with Float - The circuit furnishes an initial charge
voltage of 2.5 Volt-per-cell at 25°C to rapidly charge a Lead-Acid battery. The
charging current decreases as the battery charges, and when the current drops to about
180mA, the charging circuit reduces the output voltage to 2.35 Volt-per-cell, floating
the battery in a fully charged state.... (Tony van Roon's electronic design added
2/06) |
|
Lead Acid Charger Gel Cell - This high-performance circuit first quickly starts
(Tony van Roon's and holds) the charge at 2 amp, but as the voltage rises the current
will consequently decrease. When the current falls below 150mA, the charger
automatically switches to a lower 'Float' voltage to prevent overcharging. At the
point that a full charge is reached, Q1 will bias and the LED will light. (Tony van
Roon's electronic design added 2/06) |
