Solar power has surged ahead in recent years, and access for the individual has grown accordingly. Not waiting around for a commercial alternative, Instructables user [] has gone ahead and built himself a solar-powered Bluetooth headset.
Made almost completely of recycled components — reducing e-waste helps us all — only the 1 W flexible solar panel, voltage regulator, and the RN-52 Bluetooth module were purchased for this project. The base of the headset has been converted from [taifur]’s old wired one, meanwhile a salvaged boost converter, and charge controller — for a lithium-ion battery — form the power circuit. An Apple button makes an appearance alongside a control panel for a portable DVD player (of all things), and an MP4 player’s battery. Some careful recovery and reconfiguration work done, reassembly with a little assistance from the handyman’s secret weapon — duct tape — and gobs of hot glue bore a wireless fruit ready to receive the sun’s bounty.
Taking the initiative to go green using solar power– taken literally — could also result in getting into hydroponic gardening.
Great one that…And yes…The secret weapon- duct tape…Lol????
Most important…Thank you that you showed the circuit alongside the explanation…????
All of this to get dull sounding music. Blurtooth! Use a real headphone wire and get everything there is to hear. Saving energy is in the process. Even the phone or player is working less as it is not transmitting a somewhat wideband RF signal. A meg per second or more of bandwidth is necessary to transmit faithful sound. There is no way around it, don’t doubt for a second the bandwidth of a humble audio connection.
This certainly would make a fashion statement. :-)
