[Casing Verification + Minor Optimization] PCB Lighting Design - Ultimate Enhanced Pro+

Verification Project PCB Lighting Project - Ultimate Enhanced Version Pro - JLCPCB EDA Open Source Hardware Platform (oshwhub.com) -----------------------------------------------------------------------------------------------------------------------------------------------------
Thanks to the open source project author for providing the model. The following improvements have been made to this version:
1. Corrected the PCB orientation error of the TP4056 charging indicator light in the original project (the silkscreen of the red LED indicator light on the original PCB was reversed).
2. Added a sampling capacitor pad position for easier touch sensitivity tuning.
3. Changed the current-limiting resistor value of the LED, so the total current will be less than 600mA (the limit of the BOOST boost chip).
4. Reset the resistance value of R25 so that the charging current can reach 400mA.

Production Experience:
One day I saw a PCB light on a certain website, which happened to be available on the open source platform: PCB Lighting Project Night Light - A perfect combination of art and technology to illuminate the dark path of life. JLCPCB EDA open-source hardware platform (oshwhub.com).
However, after searching on the JLCPCB open-source hardware platform, I found the best-looking one (as of May 1, 2024): PCB Lighting Artwork (Framed Version) - JLCPCB EDA Open-Source Hardware Platform (oshwhub.com).
But printing the framed version on 3DMark costs 140 RMB, while having the framed version creator print it for 60 RMB. However, the creator prints it themselves and also assembles the outer casing. I'm rather lazy, so I ended up finding this unverified option.
 
Then I checked on 3DMark.com and saw that the unverified white casing was only 50 RMB, and the translucent one was over 60 RMB, so I decided to try verifying it myself.

Casing Description:
Because I increased the current-limiting resistor for the LED, the brightness decreased slightly. Adding a diffuser didn't seem to work well, so I just shoved the PCB in. Don't ask how I did it; just use brute force!
Then I glued the battery to the back.
The casing is a bit thick, but once the switch is on, it basically doesn't need to be turned off. It's 4000mA, what more could you ask for ?

Order the casing; you can choose between LEDO6060 or 8001 (I chose the 8001 semi-transparent one on the right; it's a bit sharp on the hand, but sandpaper is included so you can sand it yourself).

Conclusion: The reason I made this PCB drawing light is to give it to a girl (a junior high classmate I've known for almost eight years). Since graduation, we've exchanged gifts every year on each other's birthdays. I remember two years ago, I made her a PCB heart-shaped light, and last year I just bought her snacks as a gift.
This year, she's graduating again, and I wanted to make something related to my professional field, regardless of cost (this project probably took about one sheet to complete; if I used a rolled-up drawing, it probably wouldn't even cost one sheet, hahaha). Then I came across this PCB drawing light, and as you all know, I made it, hehehe~.
If you also like this light, then hurry up and make one for someone you "love," especially if you have a partner.
Oh, by the way, I'm single too.
