I doubt the glue would harm them but it would look messy.Īfter you squirt glue around the cell keep your finger on the shell of the cell/battery combo to keep it in position. ** When attaching the cell to the container I suggest this to make it easier.īe careful about getting hot glue over the solar cells. You might remember to have a moist (More wet than dry) sponge handy for the hot glue work.įirst off hot glue is dangerous if handled carelessly.ĬHILDREN SHOULD NEVER USE HOT GLUE UN-ASSISTED !!! My hope is to be able to set this in a window sill, a dashboard of a vehicle, a picnic table and know that it won't slide off for any reason. On the theoretical TOP/LID of the container I am going to hot glue some sort of non slip material. I took 3 pictures of the container/enclosure so that you could see the seal and side lock assembly. YEAH RIGHT! It's hard to take a picture of a phone charging when you are using the same phone to take the pictures. I was tired and thought I would hook up the phone and take a picture of it charging. You will see the micro USB charge cord from my cell phone. I had to do my voltage test at the center of the two diodes then subtract. I was testing things out and realized I had glued the junction beyond the last diode :(( My guess is that it will take a bit of time to charge a phone due to low amperage. I put 2 diodes in series and obtained approximately a 1 volt drop just what I was looking for.Īs you can see the meter is reading 5.11 volts un-loaded, this should work very well. Using a voltage regulator such as a LM317 would be counter productive as losses would be too great. They show a voltage drop of about 1/2 volt each. The second picture shows the zener diodes that I used. Most 5 volt devices charge at about 5 to 5.2 volts.Īs some of you know a Zener diode can reduce the circuit voltage by. This voltage will give us enough voltage to regulate it down to somewhere between 4.8 and 5.2 volts. As you can see I had 6.25 volts with out the circuit loaded. We should show a voltage of aproximately 6 volts or more. In this picture you can see the 5 cells soldered positive to negative in a series circuit.Įach battery is what is known as a 2/3 AA cell. I created an extra red wire that I used to bridge from cell to cell thus allowing me to move and locate the cells in the box at will. this creates a parallel circuit between the solar cell and the Ni-Cad battery. You will want to join both red wires together as both black wires. I used a sharp paring knife to strip the wires about 1/3-1/2 inch long. I am not one to throw things a way but in this case I tossed the circuit board and light assembly I have too much of this stuff hanging around :)Īfter the light assembly was removed I turned the cell upside down. I cut the RED and BLACK wires (positive and negative) on both the battery and solar cell right where they connect to the circuit board. The underside/base has three screws that need to be removed. Not that I am not patriotic but isn't the focus of this instructable. you will notice I took a black sharpie marker and blotted out the stars on the side of the casings. As you can see these lights were part of a July 4th celebration and thus they sold cheap the day after on clearance.
