How to Make Your Own batteries charger???

I mean the AA and the AAA batteries chargers. I don’t want to buy the charger or the new batteries. Its toooooooo expensive! Thanks ^_^

I made one myself, and it is working fine. I don’t know the materials you can get in the place where you live, but I bought one transformer (220 V-6 V-500mA) and wired the secondary in series with a 3V bulb to a diode+condenser pair to get smooth/ripple free 3V DC output. As soon as this is connected to the RECHARGEABLE batteries, the bulb goes bright. After few hours, when the charge is sufficient, the bulb goes dim and you can disconnect the batteries and remove power to transformer. Most important is not to leave the charging connected more than 6-8 hours, otherwise the batteries may get damaged.
