Basic idea here is to be able to control very cheap lamp that can be found in IKEA.
Before anything else scan QR Code with your Blynk App to get started with your dashboard already configured for this lamp.
Then first step is to disassemble typical light bulb mount found in TOMTA and separate cable from it. Second ideally you should solder leftovers of the cable to usb charger and glue it inside of the lamp, otherwise you can simply throw away the cable (assuming your micro usb cable is long enough).
Next step is to get small plastic round container I found this one in pharmacy and wrap around it your ws2812b led strip. Obviously amount of leds on the strip will determine brightness of your lamp. Wrap around the container your led strip and glue everything together with lightbulb mount.
Next step we need to solder wires going to our led strip. It's important to solder 5V pin on led strip to Vin pin on Blynk Board, otherwise you will burn 3.3v regulator that's on board. Also please don't solder VCC pin from WS2812B connector on Blynk Board to 5V as it will burn the whole board.
Din pin from led strip should be soldered to Dout pin on Blynk Board and GND to GND. Where you gonna put blynk board is up to you I've put it inside white ceramic base of the lamp along with 5v charger that powers up everything.
Lastly program your Blynk Board with my code, use QR code to scan my dashboard into Blynk. Change some things like Blynk auth key along with details for your WiFi network and you are ready to go.
