Online universal remote control plus ambient light and night light

Based on two development-free solutions of Tuya's online voice universal remote control and scene light socket, the online universal remote control plus ambient light and night light functions are produced.

The main body comes with 4 RGB lights, and 3 high-power N-channel MOS tubes on the PCB board are used to drive external power RGB light strips, turning the socket function of scene lights into

Change it to the night light function. After setting the voice scene function of the voice remote control, you can use your mouth to control the switch of the night light and light strip at night. voice

The remote control not only has this function, it can also control other products on the Tuya platform by voice, and can broadcast the weather, Pepsi Encyclopedia, alarm clock, etc.......

Therefore, this time I designed the appearance to look like a small gateway.

The window on the top of the finished product picture is used to observe the indicator light status of the two modules and the signal output of the three infrared lights.

The shell drawn with FUSION 360 still looks pretty good after rendering, but the real thing is due to printer accuracy issues.

The printing is relatively rough.

Components and graffiti modules used

Apply solder paste to the top toothpick

The three high-power MOS tubes in the component diagram are used to drive the onboard RGB and external high-power RGB light strips.

Hot air gun welding

Top surface welding completed

Use a manual toothpick on the bottom to apply solder paste

Low profile components

Low side welding completed 

Direct plug-in welding and power-on inspection

Connect external light strip for debugging

The first edition had words on the casing. When slicing, it was discovered that existing printers could not print it out, so the words were deleted and left behind.

Slice the model using CURA

Printing process (this is the second time printing the left and right shells and printing them twice)

Remove support from shell

After removing the support, use PCB to assemble it, check whether the printing size is available, and then print the other half.

Introduction to the layout on the PCB. In the picture, the light of the night light and the indicator light is emitted from the top of the housing. Direct plug infrared

lamps and RGB lights projecting out of the open window on the left

In the picture, the vertical welding light of the infrared SMD lamp also emits from the top of the casing. Plug infrared lights and RGB lights directly to the right

The shells were printed twice. The second printing was sprayed with black paint but it still couldn’t cover the printing marks. The window opening

Use hot melt glue to glue a small piece of acrylic

The above is the production process this time. The STL file of the shell is also in the attachment. You can refer to it if you need it. Please don't spray it if it is not done well. . . . . . behind is

The video link of Station B briefly introduces the use of voice remote control to control other Tuya devices. If you are interested, you can take a look. This time it was produced for an event held by Tuya. You can also enter the QQ group 634516851. There is information in the group for reference, and Tuya will push it to all major groups when it holds events from time to time. If you don’t know Tuya yet, you can learn about Tuya Intelligence. . . .
