Instruction to Make the DIY Wireless Charger
Part 1 – Getting Started
- Ensure you have all required materials and tools to build the DIY wireless charger
- Test the wireless charger PCBA as soon as received from Amazon
- Open the wireless charger PCBA and unwrap the USB-C cable
- Carefully attach the USB-C cable to the PCBA
- Set the wireless charger PCBA down on a flat surface
- Plug the USB end of the cable into your computer or wall adapter
- ENSURE it lights up, else exchange with vendor
- Plug in glue gun so it is heated up when needed
- Remove the USB cable from the wireless charger PCBA
- Won’t need this again until the end
- Prepare the picture frame for later PCBA installation
- Open and unwrap the picture frame
- Remove glass panel and set to the side
- Remove picture insert
- Flip cardboard over so the black side is facing up (towards the glass)
- Keep glass removed
Part 2 – Make Hole for the Charger’s USB-C Port
- Place the bare wireless charger PCBA into the picture frame, on top of the black cardboard
- Ensure circuit board fits; there should be plenty of space
- Place the USB-C end of the PCBA near a wall of the picture frame
- Carefully set the glass on top of PCBA, to ensure it looks as you like, visually
- NOTE: The glass will not fit in the frame all the way. This is expected. We address it later
- Remove the glass frame
- Set it to the side for later
- With the PCBA aligned in the frame as you like, use a Sharpie marker or pen to mark the left and right sides of the USB-C end onto the picture frame
- We need the USB-C to be exposed outside of the frame
- Sorry the black Sharpie is a little hard to see in the pics
- NOTE: We want the metal of the USB adapter on the chip to be exposed but the green laminate should stay inside the frame.
- Remove the wireless PCBA AND black cardboard background from the frame
- Set to the side while we work on the frame
- Using your utility or exacto knife, carefully, cut a small gap in the side of the picture frame for USB cord to plugin
- Cut to the depth of the USB-C port
- Remember it is better to cut too small at first and widen later so the adapter will fit
- TIP: Use a pair of needle nose pliers to help peal the thin tab/lip back from the frame to easily cut the bottom
- Put cardboard back (black side up) and wireless PCBA back in the picture frame with the USB port lined up
- Make any adjustments to the USB port cutout BEFORE moving forward
Part 3 – Secure the DIY Wireless Charger
- Place 1/2” bumpers at the 4 corners of the picture frame on the black cardboard background
- My bumpers have 1 sticky side, so I used small pieces of blue paper to STOP THEM FROM STICKING because we need to test placement before adhering to their final postion
- Placing the bumpers in the 4 corners will line up perfectly with the picture frame’s supports
- WITHOUT SECURING the 1/2” bumpers, place the glass on top of the frame and spacers
- Ensure the glass is no longer pressing on the wireless PCBA components. That is, the bumpers fully support the weight of the glass frame
- Ensure the bumpers are stable when pressing the glass down
- You may want to take a picture or mark points of reference for later when securing
- Remove the glass and set to the side
- Remove the 1/2” bumpers from the frame, so we can work with the PCBA and frame
- Use a lot of hot glue to secure the USB end of the chip to the cutout in the frame
- Lineup the metal USB end with the hole we cut in the frame earlier
- Remember, the green chip should remain inside of the frame with only the metal port emerging through the cutout
- DO NOT GET glue in the USB-C slot (it will be a pain to get out)
- TIP: Fill the port with small, wrapped rolls of loose paper to avoid the hole getting glue in it
- Apply hot glue. Be liberal with the glue
- May consider securing the chip on the backside with glue so it is equally supported from pressure
- Must support the pressure of plugging and unplugging the USB-C end into the the power cable
- Lineup the metal USB end with the hole we cut in the frame earlier
- Wait for the glue to dry
- Remove paper from the USB port
- Carefully scrape away any glue that may have got on the cardboard or frame
- Scrape away excess glue from the top of the USB port, so it is flat and the glue is not taller than the frame side.
- When the glass is placed it must be aligned with the top of the frame
- USB port should be visible
Part 4 – Finale – Add the Glass Top to the Wireless Charger
- Plugin the USB-C cable to the port of the glued wireless charger PCBA
- Place the 1/2” bumpers in the location we planned earlier. Then using a small amount of hot glue, secure the 1/2” bumpers to the black cardboard where you previously marked
- Apply small amount of glue to one side of each bumper, one-at-a-time
- Place in designated position and apply pressure to each for a few seconds while glue cools
- Do this even if your bumpers are sticky!
- After all 4 bumpers are secured, one at each corner, place the glass on top of the frame to make sure everything aligns nicely
- Use utility knife to carefully remove any tall points
- Test the charger BEFORE moving forward!
- Plug it in
- Put phone on charger
- Ensure charger is working through glass and all functions as expected
- Secure the glass to the 1/2” bumpers
- Lift the glass and keep it nearby
- You’ll need to quickly line this up with the 4 corners of the frame and secure the glass before the hot glue cools
- Make sure you have enough hot glue in your gun to do ALL 4 at once!
- Quickly and precisely apply 4 small dabs of hot glue to the tops of the placed bumpers
- Line-up the 4 corners of the glass top with the 4 corners of the frame
- Place the glass onto the 4 bumpers into the hot glue
- Hold frame together briefly
- Let glue cool
- Lift the glass and keep it nearby
- (optional) Add 4 of the 1/2” bumper protectors to the bottom of the charger to act as non-slip feet
- I decided to keep mine flat on my desk instead of raising it with the non-slip feet
- 🎉 Tada! Your DIY Wireless charger is done and fully functioning!
