Introduction: Solar Hummer Re-done
This is an improvement on my previous instructable, https://www.instructables.com/id/solar_rc_conversion/ the steps will all be the same and stuff but I'll show you how to add some neat little gizmos to it at the end.
Step 1: Materials
Here's a list of what your going to need,
A rc Hummer from Radio Shack ($7.99)
A screwdriver flat and philips
A solar walkway light with a 3v solar panel (try a used one from a second hand store)
A roll of electrical tape
A skill knife
A soldering iron
A set of pliers (if you think it would help)
A set of wire cutters (you could just about de-solder every thing that these could be used for but if you don't want to, cut it)
A set of wire strippers (optional)
And a pack of two rechargeable AA batteries.
Step 2: Getting Ready Part 1
You will need to take the Hummer out of the box and put the batteries in. if it works, take them out and set them aside. Now, unscrew the body of the hummer and remove it slowly. make sure not to detach the antenna wire, it will give it less range. Set the body next to the chassis. Most of the wires inside are very easily broken. If you need to, put some tape over them.
Step 3: Getting Ready Part 2
Take the solar light and open it. This process will be different for every project. Your goal is to find where the two leads from the 3v solar panel meet up with the circuitry and take it off. In the picture i already have the solar panel.
Step 4: Atomatic Sunroof
Your going to need a hole to run the wires through in the roof. I found a nice one. The plastic for the sunroof is pretty easy to cut through. Just slice it off or make a hole if your solar panel doesn't cover the whole thing. While you have the knife you can cut off the axle housing so that the wires from the panel can be soldered in.
Step 5: The Juice Supplier
To determine the positive and negative could be tricky. In case you solar panel is not color coded, red = +
black = -, then hook it up to a volt meter and if it says you have them backwards then switch the presumed positive to the other side.If you would like to paint this model you should do it now. You need to paint the car before you put the wires in so you don't paint the solar panel. To paint it just put tape over anything you dont want to paint. Then spray it. You can now solder the Wires in.
Step 6: Final Stages
Put tape on all of the exposed wires so that the don't touch anything and then screw the body back on. You could use tape to hold on the solar panel as well as hot glue. Put the batteries in and take it for a drive. It still should work. Now, when the batteries run out you just have to leave it outside for a while. Haha! My mother always told me not to leave my toys outside. If you don't intend to read on, (as for the basic model is finished) that's OK. Thanks for reading! Vote for me in the Epilog Challenge !
Step 7: Now for the Fun Stuff!
This is the reason I remade the whole instructable. I made some modifications. I added and some leds, bigger wheels and I painted it.
Step 8: Lights Up!
This is the light mod. Your going to need 2 LEDs of any color. Take the top of the hummer off and hotglue them to the headlight plastic things. Solder the positive and negative of the two LEDs together. Then you will essentially have one big LED. Solder the positive to the positive of the electric motor and the negative to the negative. Screw on the top and your done.
Step 9: Super Size!
To make the wheels bigger you can rap them in rubber bands or just altogether replace them. They will probably be the same size as a model cars wheels. If they don't fit you can put some hotglue on the inside and quickly slip them on the axle.
Step 10: Make the Switch
The picture explains better.
