How to Make the Ultimate DIY Electronics Helper

This DIY device combines a 12V high-speed motor with a portable power source and an efficient fume extraction system. Powered by an 18650 battery and managed by a TP4056 charging module, it provides a steady 12V output using a MT3608 boost converter. The flexible exhaust pipe directs fumes out through a window, making it an essential tool for electronics enthusiasts and makers who need both power and safety in their workspace.
Supplies
- 18650 Battery with Holder
- TP4056 Module
- MT3608 BOOST-Module
- Terminal Block Connector 2 pin
- ON/OFF Switch
- Acrylic sheet 3mm
- 12v High Speed Fan
- Flexible Pipe
Prepare the Acrylic Sheet


- Take a 3mm thick acrylic sheet.
- Cut it into a rectangle shape according to the size you need for your project base.
- (Tip: You can use a laser cutter for clean edges, or a hacksaw if cutting manually.)
Mount the Charging Module and Battery Holder





- Apply strong adhesive (like hot glue or acrylic gum) on the acrylic base.
- Fix the TP4056 charging module onto the sheet where you want easy access to the charging port.
- Next, fix the 18650 battery holder beside the TP4056 module.
- Make sure everything is aligned neatly and firmly attached.
(Tip: Leave a little gap between the holder and module for easy wiring.)
Complete Battery Connections






- Again, use thick copper wire for strong connections.
- Solder the negative (-) wire from the 18650 holder to the B- pad on the TP4056 module.
- Solder the positive (+) wire from the 18650 holder to the B+ pad on the TP4056 module.
- Make sure both connections are firm and there are no short circuits.
Mount the MT3608 Boost Converter





- Fix the MT3608 boost converter module onto the acrylic sheet using adhesive or double-sided tape, just like shown in your image.
- Solder the negative (-) input pin of the MT3608 to the OUT- pad of the TP4056 module.
- Ensure the connection is solid and neatly routed to avoid messy wiring.
Attach a 2-Pin Terminal Block to MT3608 Output



- Take a 2-pin terminal block (small size fits best).
- Solder the terminal block to the OUT+ and OUT- pads of the MT3608 boost converter.
- Make sure the block is aligned straight so it’s easy to connect wires later.
Add the Slide Switch for Power Control






- Take a small slide-type ON/OFF switch.
- Fix the switch onto the acrylic sheet near the TP4056 module (so it’s easy to reach).
- Solder one leg of the switch to the OUT+ pad of the TP4056.
- Solder the second leg of the switch to the VIN+ (input +) of the MT3608.
- This switch will now control the power going into the MT3608 boost converter.

Cover the Sides With Clear Acrylic



- Cut clear acrylic strips (3mm thick) to match the sides of your main acrylic base.
- Make holes in the acrylic strips where needed (for charging port, switch, etc.) — as shown in your image.
- Fix the strips carefully around the sides using strong adhesive or screws (if you planned for it).
- Make sure all ports and switches are easily accessible through the holes.
Insert the 18650 Battery and Set the Output Voltage





- Insert the 18650 battery into the holder, ensuring the correct orientation (positive side facing the right direction).
- Turn on the slide switch to power the system.
- Adjust the MT3608 boost converter to output 12V by turning the small potentiometer (using a small screwdriver).
- Check the output voltage using a multimeter to make sure it’s stable at 12V.
(Tip: Adjust the potentiometer slowly to avoid over-driving the circuit.)
Connect the 12V High-Speed CPU Motor and Final Assembly







- Connect the 12V high-speed CPU motor to the terminal block for easy power control.
- Ensure the motor is correctly connected to the MT3608 output for 12V power.
- Close all sides of the acrylic box carefully to fully enclose the components.
- Apply strong adhesive (gum) around the edges of the acrylic to ensure everything stays securely in place.
Attach the Flexible Pipe for Exhaust




- Take the flexible pipe and insert one end into the back hole on the acrylic enclosure.
- Use strong adhesive (gum) around the edges of the pipe to secure it firmly in place.
- Make sure the pipe is positioned in a way that ensures proper airflow for the motor’s exhaust.
Final Charging Setup and Fume Extraction







- Charge the battery through the TP4056 module. Simply connect the charging cable to the TP4056 input, and the battery will charge safely.
- To enhance safety and usability, solder additional wires near the TP4056 for easy access to the charging port.
- Ensure that all fumes from the motor are effectively absorbed by the flexible pipe, which leads to the window for proper ventilation. This will help in preventing any hazardous fumes from accumulating inside the enclosure.
