Humidity control by Arduino | I repair Dry box for camera

- My dry box has been broken. Unfortunately, I can't find controller spare to renew. So, I try to use Arduino Pro Mini to replace its controller MCU.
How to do?
1. Understand how dry box works: Maker use cooler plate to condensate water in the box, then water will be taken out by osmotic material.
2. Try to read current PCB, then take out old MCU
3. Soldering cable from PCB to connect to Arduino Pro Mini
4. Write program to control cooler plate, receive SV %RH, show %RH and *C, turn on lighting

Part to make (in case you want to make dry box DIY)
1. Arduino Pro Mini amzn.to/2xy4yFn
2. Cooler plate amzn.to/3EHKSBU
3. Humid sensor amzn.to/3eQGP6V
4. PCB
5. Button
6. 7-Segment
Part to purchase (dry box - complete set)
amzn.to/31BAOqZ

Nice project.
Nice project thanks for sharing. My dry cabinet controller failed too but because humidity sensors lose calibration over time I decided to permanently drive the peltier module with a current limit. Works well at around 3 watts and keep the humidity in the safe zone.
Max Phipps your way is also ok. If wish, you can add sensor and screen for precise control
Hello, thank you for this video. Im trying to do a dry box, already have the controller but im just confuse with the Peltier. I have Peltier TEC1-12706 12 V can i just use this ? Thank you for help and greetings from Portugal.
Hi I need Dry Smart brand 80l cabinet display
do u have clip about controling stepper motor ? i have driver G201 do u know it ?
plz help me
so in principe I can make any cabinet "dry cabinet for camera" .. only it has to be modified - air-tight maybe insulated and with small peltier and adurio I can make this for it .. Am I right ?
I found 200 eur for small cabint too expensive.
this can be nice project :)
Let’s say, if you buy a dry cabinet 200eur, you will have a cabinet ready for use and save your time. But if you do your own dry cabinet, it would take you a lot of time to work with Peltier, Arduino and troubleshooting. If you are a person who would like to make a hobby project, then you can make it
Hi, great work! My cabinet is currently down after years and I wish to make it smarter with arduino controlled humidity. I saw that there are a few transistors (or mosfet?) between the Peltier, Light, and 7 Segments Display. Do you have any idea what can I use for each of that? Thank you.
You have to understand the origin PCB where it use Mosfet to control cooling plate. You should take signal control Mosfet to connect to arduino and control humid by your program
@@engineer2you I saw the one in my cabinet was D882 transistor, for controlling the cooling plate. Do you think D882 will works if I trying to adapt it with your setup? Or any recommendation for what mosfet that's suitable for TEC-4095? Thank you
Hi, I'm using same brand drybox as well, have same problem as yours, the atmega8l-8au(in your case its unknown mcu, but my guess it is the same chip) chip was burned, can i just replace the chip after reprogram it? Or i still need to use arduino mini to control the controller? Great video 👌
MH cbrians you can do it with your idea: replace the chip to pcb, but i think the pcb will have some pin for programming. I guess you will need many times to re-program the chip, you can’t program just 1 time and got successful. Good luck
@@engineer2you yeah right now i had to bypass the controller, i feed 5vdc directly to the peltier module. But it seems like it cannot go lower than 60%. I will try getting new chip & do it my way, if i didn't manage to do it then i will follow your way, thumbs up for easy to follow guide, already subscribed ✌️
Hello, very interesting but as I'm rather inexperienced, a simple question. Is the "old PCB" actually necessary ? Or are you using it only to reuse the buttons & display that were in place. Is it possible to "build from scratch" using your instructions ? I think yes. I'd like to build such piece to convert a "normal cabinet" into a dry cabinet (adding insulation too)
Thanks in advance !
I would think I can just plug everything (buttons & digits) into a new breadboard linked to a arduino :-) , correct ?
You are correct, I try to use old PCB because I want to reuse the button and display. You can build from scratch to make new dry cabinet.
@@engineer2you thanks !
Hello, did you manage to build your dry cabinet without the old PCB? I just bought one but the previous owner removed the PCB. I'm very interested if you found a solution.
Thanks in advance!
Hi, the Aduino need to be program ?
Yes. It needs to be programed
@@engineer2you I see, my controller just down today. I think I might change the controller since I dont know how to program it
The link for the cooling plate from Amazon is not working. Can you put a new one, please? Than you so much.
Here it is amzn.to/3EHKSBU
@@engineer2you Thank you so much.
@@engineer2you Just more one question, the hot part of the pettier stay face to inside of thee cabinet ? And the cool part attach to the back of the cabinet? Thank you so much more one time . Treating from Portugal.
@@lisboasuave-theroyalteahou3717 it is reverse your thinking: hot side of Pettier is outside the cabinet; cool side of Pettier is inside the cabinet. Cool part (inside cabinet) will condensate water (in air of cabinet) -> water will come out cabinet by osmotic material. Hot side of Pettier should be cooling (naturally by heat sink), if hot side is in cabinet, maybe cabinet will get hot gradually
@@engineer2you Okay, I think I understand now. Will give a try , I’m just waiting that peltier arrive from Amazon. Thank you so much for the help :)
my dry cabinet displays blink what to do
mango production you follow my project, and now the display was blinking? Or your original cabinet display was blinking?
@@engineer2you my original cabinet display was blinking
mango production let’s check your power supply adapter. Maybe it is broken, not enough power for cooling plate
@@engineer2you ok thanks i will check
Not a good use of time. You bought it. It didn’t work. So u fixed it instead of sending it back?
Waterlife i bought it, it working perfectly about 6 years, then stop working. Instead of throwing away, i repaired it to save cost
