Soldering a flex wire to a single solar cell to be used as a detector. Some tips and tricks to make it faster and easier while lowering the chance of cracking the cell. (This is not the same as building a solar panel.)
MATERIALS
- Soldering iron (less than 50 watts, clean)
- Fine solder is best (clean)
- Thin, flexible wire (clean)
- Cell
WARNINGS:
- Soldering can be dangerous. If you do not know soldering safety, learn it or don’t solder.
- Never solder live circuits of any type.
- Soldering house wiring, power wiring, etc. is outside the scope of this video. That should be left to professionals only.
- Electricity can cause damage, fires, burns and death. If you don’t know about electricity, learn before doing.
- These are demonstrated for hobby work, low voltage – low amperage applications. NOT for mains voltages or currents or similar.
- Never use lead type solders where it will come in contact with food or drink or where it will come in regular contact with people.
- Lead is toxic. Take care to ensure that the byproducts / waste are contained and disposed of properly. Never hold solder in your mouth. Have proper ventilation.
- This is for hobby soldering only. Industrial users have more stringent requirements for industrial or large scale soldering operations.
- This is not all inclusive. If you don’t know, get training before continuing.
