A nightlamp with Bluetooth audio capabilities

My nightlamp was off, its non-rechargeable batteries had died.

I personally find non-rechargeable batteries very useless and quite expensive in the long run.

Here the idea came to me, "what if I make this nightlamp rechargeable". I had some rechargeable batteries from an old laptop charger. Some were bad but I found this one which was still in a good condition

"But how was I going to recharge the battery?" I had no li-ion battery charging module. I paused and chewed on this for I while. I needed this project to be over soon before nighttime for me to enjoy the lamp.

On my electronic pile came the savior:

A Bluetooth module with a charging circuit....The perfect solution to my problem but an OVERKILL; it has audio and FM capabilities.

Here came the killer idea "A nightlamp that not only has a rechargeable battery, but also Bluetooth audio and radio FM capabilities! "

From there there was no going back, it had to be exactly that! The idea itself made my blood warm!

The old laptop willingly without hesitation offered me some 4 Ohm speakers:

"Thank you buddy." My hands were all over. There was not a single distraction in this project, it was a creator's 'perfect world'.

Soldered the bulb and the switch to the battery together with the connector to the Bluetooth module:

Immediately came up with the layout of the components in the enclosure and attached the battery securely through my improvisation skills.

The next step was a challenge; I needed to find a place for the Bluetooth module and there was not one where it could stay concealed mysteriously. Here are the module's 'uncompromisable' demands;

• The buttons had to be accessible to the user for channel and volume change.
• The type-c connector had to be accessible for charging.

Here is what I ended up doing:

I know, it is in no way sleek and aesthetic I apologize to those with a keen eye. I swear it also makes me feel like I need saving. At the moment I had no reason left in me.

At this point all connections were made. I chose to go with one speaker since it was just a nighttime listen not a Sunday morning gospel playlist.

I powered on the module;

Came a soft "Bluetooth mode."

Tested the charging, it was okay, sorry I don't have an image of it charging. It just glows red.

My main target was the FM so I soldered a long cable with no particular consideration to antenna design and impedance matching. I was flying. Double pressed the power button to scan for stations.

The rest of the day was spent on the bed admiring my creation listening to classic music on FM radio.

Final reveal;

It came to me that the world cup(2026) was starting the same day. What a sweet coincidence!

Here I was following the Mexico vs South Africa game. GoMexico!
