HowTo: Tasmota - Build your own Retro-Bulb-Smart-Home-Lamp - Nerdiy.de - Nerdy DIY HowTo's about electronic, 3D-printing and more.

Some may be recognized in the Retro speaker project, that it is a small hobby of me to give old things a new benefit. If you can also improve the old technology and make it more energy efficient, this is a great icing on the cake.

It was the same way lately when I tripped over a box of old light bulbs. I did not want to use them any more, because in the meantime, I'm also using this new-fangled trend to really use the heating for heating.

But it was a shame to throw away the old lamps. So I decided to give the old "stupid" light bulbs a new intelligent inner life. At least a handsome lamp for decoration should be build with it.
How to do that and what you have to consider for a replica I described in the following article.

Hints for our lovely english readers: Basically, many of the articles on Nerdiy.de are translations from the original german articles. Therefore, it may happen here and there that some illustrations are not available in english and that some translations are weird/strange/full of mistakes or generally totaly wrong. So if you find some obvious (or also not obvious) mistakes don't hesitate to leave us a hint about that in the comment section.
Also please don't get confused, that instead of a "dot" often a "comma" is used as decimal separator. 🙂

Safety instructions

I know the following hints are always a bit annoying and seem unnecessary. But unfortunately, many people who knew it "better" from carelessness lost their eyes, fingers or other things or hurt themselves. In comparison, a loss of data is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Even the coolest project is worth no injury or other annoyance. https://www.nerdiy.de/en/sicherheitshinweise/

Required tools:

In the following list you will find all the tools you need to implement this article.

Put together the required parts

To build your Retro Bulb Smart Home Lamp, you will need the parts shown or in the parts listed under Prerequisites. As far as the ESP8266 adapter board is concerned, this does not necessarily have to be a Wemos D1 mini. However, this is one of the smaller adapter boards on the market and just because of this, there is at least in the 40W version nearly no alternative – the larger adapter boards just do not fit so well in the lamp base.

The light bulb should already be "gutted". How to do this is explained in the article **"de-core" light bulbs**.

The lamp base holds the light bulb upright later and also hides the ESP8266 adapter board.

The six WS2812B LEDs provide the lighting for the lamp. Their color and brightness can be adjusted later via a web interface.

Here you will find the schematics that specify how the lamp is basically constructed.

Attach LEDs

The first step to your own retro light bulb smart home lamp is attaching the LED strips. These should already be tailored in pairs of two.

Then glue the first LED strip on the side where the hole is in the base of the lamp base. Here is the line later, which connects your ESP8266 adapter board with the LEDs. It is important at this point that you pay attention to the "direction" of the LED's. At this point the black arrow on the LED strip must face upwards – ie away from the hole.

Then the next LED strip is glued on. Here, the "direction" is changed again - so the black arrow points down.

The last LED strip is glued to the only remaining free space. The "direction" is changed again. This time, the black arrows on the LED strip are pointing upwards.

Solder the first LEDs

As the LEDs can also be supplied with energy and data (color, brightness, etc.), they must of course be connected to the ESP8266 adapter board.

For this you need a 20cm long 3-wire cable.

Strip the individual wires approx. 3-5mm…

… and tin the vacant cable ends. Tips for dealing with the soldering iron can be found in the article Electronics—My friend the soldering iron.

Then you can insert the wire into the shaft of the lamp socket …

… and solder to the contacts of the first LED strip. Pay attention that the "direction" of the LED strips are correct. The black arrows must point away from the connecting lead at the first LED strip.

Connect LEDs to the ESP8266 adapter board

Before the other LEDs are soldered, the ESP8266 adapter board is first connected to the supply lead to the LED's, because this way you can use the resulting cable residues.

Before you start with the installation of the ESP8266 adapter board I also recommend you to remove the integrated LED of the adapter board if necessary. Unfortunately, this lights so strong that it is otherwise visible through the plastic of the base. How to do this is described in the article ESP8266 - Remove/Disable LED.

The supply line should already look out of the socket. Splits the single wire up to the exit hole in the socket …

… and stick the ESP8266 adapter board in the socket. This works very well with thicker double sided tape or some hot glue. It is important that the USB port of the adapter board points in the direction of the bulge in the socket. Only then can you connect the lamp later to a USB cable.

Have you attached the ESP8266 adapter board and aligned accordingly, you can …

… shorten the wires so that they last about 3-4 cm.

Strip here again about 3-5mm of the wires and …

Also prepare the contacts of the ESP8266 adapter board by tinning the connection contacts "D2", "G", and "5V" in advance.

have you tinned all the places, you can …

… solder the wires. Make sure that the wires connect the right places between the LED strip and the ESP8266 adapter board. "+5V" of the LED must be connected with "5V" of the adapter board, "GND" of the LED with "G" of the adapter board and "DIN" of the LED with "D2" of the adapter board.

Here again a close-up of the soldered wire.

Solder the remaining LED strips together

So far, only two of the six LEDs or one of the three LED strip elements are soldered together. To solder the remaining LED strips, you can now use the trimmed line remnants from the previous step.

Before you can start connecting the LED strips, you should prepare all contact points again.

Tin the contacts on the top of the first LED strip.

And also the upper and lower contacts of the second and …

In order to connect the remaining LED strips with each other, you prepare six pieces of cable about 2cm long. Strip the ends of the cable again about 3-5mm and tin the cable ends.

Since you already prepared the contacts on the LED strips, you can solder the first three connection wires already.

Here is a closeup of the first three soldered wires.

You can now bend this and connect it to the second LED strip. Make sure that you connect the right contacts. "GND" from the first LED strip must also be connected to "GND" of the second LED strip. Also "+ 5V" with "+ 5V" and "Dout" of the first strip with "Din" of the second strip.

Closeup of the soldered wire on the second LED strip.

Closeup of the connection between the first and second LED strip.

Now you can solder the remaining three wires to the second LED strip.

Closeup of soldered wires on second LED strip.

These can then be soldered to the third (and last) LED strip.

Have you soldered all LED strips the whole part should look like this. Check again at this point that you have soldered the leads to the correct contacts.

Further picture of the soldered LED strips.

The soldered wires should now be placed as tight as possible around the lamp base.

... so you have no problems later to push the LED's including lamp base in the "de-cored" bulb.

Program the ESP8266 adapter board and perform the first test

After the last solder joint is cooled down, it's time for a first test. Play the Tasmota firmware on the adapter board and test the LEDs. How to do it is described in the article Tasmota - firmware flashing.

In the following a configuration how I used it for my lamp. Of course, you have to configure the access data for your WiFi and, if necessary, the access data for your MQTT server.

Glue the thread compensation to the lamp base

When I first set up this lamp, I had the problem that the not quite flat bulb socket on the lamp base was not properly upright. To compensate for this unevenness, I glued a balancing ring on the lamp base. I then integrated this into the lamp socket. For the sake of completeness, it is listed here anyway.

Close-up of slightly uneven lightbulb thread.

With the compensation ring glued to the lamp base, the incandescent housing is now …

The balancing ring can best be fixed with a little hot glue.

Combine bulb housing with lamp base

Now you can also combine the lamp housing to the lamp socket.

Now you can carefully put the bulb case over the rod base. If everything fits you could glue the light bulb housing with some hot glue with the lamp base.

Size comparison between "small" and "big" version.

Illuminated, the whole thing looks like this.

Other construction options

If the 3D printed plastic lamp socket does not appeal to you, you can also use a base made of a wooden board. There is also another adapter with which you can attach the light bulb housing on the wooden plate.

The STL file for printing this lamp base can also be found in the upper "3D parts" area.

By combining with different types of wood or plate you have even more possibilities to modify this project according to your wishes.

Have fun with the project

I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂

P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you appreciate that I share this information with you, I would be happy about a small donation to the coffee box. 🙂
