Depending on the table lamp you are going to use to house your charger f, your design will vary and thus the parts and equipment required will to. Below is a generic list based on what we used, it is not complete but should give you a pretty good idea.
- Low voltage table lamp (anything between 7-24v will work, we used a 12v one from B&Q).
- 5V USB DC 7V-24V to 5V 3A Step Down Buck Converter Module.
- Snap-in Miniature Round Rocker Switch Black (to turn the light on and off).
- Wire, we used speaker cable
- Hot Melt Glue
- (Optional) Sticky backed felt.
- (Optional) Heat shrink tubing
- (Optional) Larger AC adapter, without this you will not be able to charge and use your lamp at the same time, one capable of supplying 650mA and 3000mA is best with appropriate connector for your lamp.
Tools & Equipment:
- Basic hand tools e.g. screwdrivers, wire cutters, craft knife, spanner, a hammer, pliers etc.
- Something to cut the slot in the lamp base for the usb socket case with, most likely a Dremel.
- A drill and drill bits for the hole for the lamp power switch, the biggest drill we had was only a 10mm a step drill would of made things a lot easier!
- Small round and flat files,to tidy up your drilling & cutting.
- Soldering iron.
- Hot Glue gun.
You will of course also need somewhere to work, best not make this on the dinning room table, not unless you want to be explaining the soldering iron burns!
