Create Your Portable Rechargeable Table Lamp
The bulbs aren’t particularly expensive, but if you’re looking to make your own little portable bulb, Instructables user Saiyam has a guide to making one with a rechargeable power supply.
The assembly here isn’t overly complicated, but you need to know a little about electronics to get the job done. The total cost is only about $ 5. The end result is a very bright little lamp that you can move where you need it without worrying about the power cord. Head over to Instructables for a complete guide.
