Sydney at 8 months. |
During January I will be working on some solar lighting using 12 volt DC Light Emitting Diodes (LEDs) prototypes for the Deaf Church and some molds for casting VIP Latrine Floors. I have ordered a 5 meter long LED light strip roll that has 300 LEDs on it and another style of LED lights that has 80 LEDs. The reason I am looking a the LED lights are that for the Deaf "No light means no talk.". There is an Danish organization that is willing to pay for a Solar Panel for the Deaf Church. In the past the Solar lighting systems have been a panel, a lead acid battery, and 12 volt incandescent car lights. The system I am looking at will be similar except I will include a modern charger controller that prevents the battery from over charging and a battery protection circuit to prevent the battery from discharging too far. The modern LEDs provide the same Lumens of light as incandescent lamps but only use 10 percent of the power. I bought them off of Ebay. The vendor from China estimated delivery between January 2nd & 10th.
As I get closer to the trip I will update you on what is happening.
January 1st Update: I received the LED's in the mail yesterday. My power supply that I currently have is only 2 amps (24 watts at 12VDC). The string of 80 lights uses less than 1 amp. The string of 300 uses 72 watts around 6 amps. I found my old battery for our self starting lawnmower and charged it up. It is 6 1/2 years old and has been out of the mower for years.
