- I made a tic-tac camera that can be easily taken out and used at any time using a tic-tac case. It's battery operated and charges the battery with wireless charging.
SD Card $? (You may have an sd card that is not in use.)
Tic Tac $2
ESP32CAM $6
LiPo Charger $7
Battery 3.7V 150mAh $3
Qi Wireless Charger Receiver Module $3

So cool
you are very smart and creative.
Happy birthday.
A question. Will I be able to access the camera through the 4G network?
thanks
That's a good question. Yes, it is possible. To do that, you need something to connect to an external network (public IP), not the local network.
There are many ways. Among the projects I did, I set up a server on the external network (Google Cloud Platform) so that I could watch the images of ESP32CAM on my phone (LTE). Please refer to this project. th-cam.com/video/CpIkG9N5-JM/w-d-xo.html
You can also use it by installing an MQTT server on AWS. th-cam.com/video/aY7i0xnQW54/w-d-xo.html
nice little projects, i have 2 questions:
- you are storing the file counter on eeprom, i've read that the write cycle of eeprom is very limited (10000 to 100000), do you have any eeprom failure experience with esp32?
- which version of core for esp32 you use? the github is on 2.0.0 but the boards manager shows 1.0.6 as last.
In my case, the problematic case was that the stored value could no longer be read due to an overflow of the EEPROM. Other than that there were no problems. The version I'm using is 1.0.6.
I like this project. Very NhAAise..
Btw. Is the battery not swollen?
Haha. It's been like this since I got this battery. There doesn't seem to be any particular problem.
Thanks for sharing, great idea. I'm just wondering.. would it possible to use SD card slot as a heat sink for camera? It seems that metal plate on the back of the camera is not connected and SD card slot seems to be grounded.. So would it be a problem? I see that you put there adhesive or something similar... Currently I'm implementing similar project although without battery, but I was thinking about cooling possibilities... Thanks
I don't think a heatsink over the SD card slot will help much. Honestly, I have no idea. How about attaching it on top of the ESP32 chip on the other side?
My idea was to use SD card slot as a heat sink for camera chip itself. It seems that camera chip seems to be overheating. ESP32 probably don't need a heat sink. I thought it would be quite useful to attach camera chip to SD card slot, so that the slot itself would serve as a heat sink. But I'm not sure if there is any risk of short circuit..
@@diffieke I don't know about that either. I hope you just give it a try.
Nice video, and interesting project, thanks for sharing it. It is a pity that LED is active when the SD interface is used, this is a bit of a design flaw on the esp cam in my opinion
Agreed. It seems to have been designed this way due to the lack of GPIO.
@@ThatProject does it overwrite older footage when the sd is full ? i want to use this in surveillance for front door
I would love to use your project for an ebike rear view camera. Do you have any tips or things you might want to change after making this? Wide angle lens or ND/IR filter?
That's cool.
Which device will you use to show the incoming images from ESP32-CAM? How to connect your ESP32-CAM?
@@ThatProject I suppose I would use 120 or 160 degree fisheye. I have a few older cellphones I want to make a bike computer with. I could maybe use matter or VLC for video feed. Or a stand alone server. I have three standard esp32 cams but no serial ch340/usb Uart/FTDI yet. Have you ever programmed esp32 with a pi B+?
@@Lordsbassman Never programmed ESP32 with Pi. Okay! I hope your project goes well.
Thanks for sharing, where i can buy the Qi wireless receiver ?
You can buy it from any open market. amzn.to/42Y73Nn
How long does that 3.7v 150 Mah lipo battery last on continuous playing?
How long does it take to recharge after it drains from continuous play?
Thank you for your help :)
I was able to use it for about 20 minutes, and I think it was possible to fully charge it with wireless charging for about an hour.
Hallo...
I'ld like to use this project with a little solar power...
That would be awesome. I would like to use DC from a bike tire generator.
What is the back up duration of the battery,how long does the battery work.
As you can see in the video, it uses a very small capacity (150mAh) battery. Continuous shooting is possible for about 30 minutes.
How do you keep the camera from shutting down after a few minutes? I am using 18650 cells with a USB charging/supply board from Alibaba and after a few minutes, the camera shuts down. At first thought, the caerma was overheating but when the camera is plugged into the USB/115VAC wall plug it works flawlessly.
What kind of USB supply board do you have?
@@ThatProject MakerFocus Dual USB 5V 1A 2.1A Battery Charger Module Board For DIY Power Bank. Bought it awhile back. It would be nice if there was a spec I could look up avoiding the purchase of similar boards.

On this board, did you connect the battery to BAT +, - and connect the ESP32-CAM through the USB port?
If so, there doesn't seem to be anything in particular to be a problem.
Does the OUT display appear well when outputting on the screen?
Wouldn't this board automatically power off if the power consumption is too low?
@@ThatProject Connections are OK and the pack works just fine on devices that draw more than the Camera board. I can't find my USB power monitor so can't say what the low current shutdown should be. As far as the board shutting down be normal as you state don't know and is why I was asking the question originally. It would be great if these boards stated they would shut down if the current draw was to low.
This battery 3.7V and 2500mAmp battery doesn't works with any of my ESP32Cam module. I have tried 4 modules from different sources.
The video is stable only when provided 5V voltage.
Yes, that's right. A 5v supply is required to get a stable running. This is why I use the charger module in this project.
Is there overheating in the module?
Of course, if you continue shooting, it will heat up. However, there were no overheating issues. I think a lot of people want me to test for temperature issues with ov2640 and ov5640. I'll try it sooner or later.
