So in summary - there is nothing wrong with DHT22 (especially compared to DHT11, which is used by majority of makers for unknown reasons). You just chose not suitable sensor due to wake-up time and minimum power consumption requirements.Anyway - have you checked, that temperature from IC (specially ESP) does not affect temperature in sensor? I have already encoutered, that may desings does not care about this and temperature reading are affected by ambient heat of the chips. Some of the makers are even stacking temperature sensor right on top of the main chip.

Why did you choose value 500 as sensos indication of alcohol? In human breathe there is some (minimum) level of alcohol naturally occuring in breath. Why did you choose this level? Does it have any correlation to BAC?

Every bird needs different entering hole. Some of them will not move in when the hole is too small or too large (yes, even too large hole matters). Have you checked the dimension of the hole?

Those TP4056 has overcharge protection, so you can keep them in charger after full charge.

- PospaPunk commented on muhammed.lutfi61's instructable DIY Lipo Powered MouseView Instructable »
Since your mouse looks for one AA battery with voltage 1.5V and your LiPo has charged voltage 4.2V i don't recommend this. Even if it works for your mice it can immediately destroy different mouse. And there is no over-discharge protection. Why you didn't use the version of TP4056 with over-discharge protection and output pads?

- PospaPunk commented on Michal Choma's instructable Charging Lithium - Ion Battery With Solar CellView Instructable »
That is my point. Even if the module with output pins is used, it seems it will still charge the battery when load is connected. Overcharging LiPo may damage them or even worse.

So you just connected few LEDs with battery. Everybody knows how to do that. But the most important - how did you make a good flying kite?

I read here (https://www.best-microcontroller-projects.com/tp4056.html) that "If you have a load connected to the battery then this will change the current detected so the TP4056 may never terminate the charging process.".I would like to know your opinion, sice i think most users will use it for charging with load.
- PospaPunk commented on hirfan789's instructable How to Use a While Loop to Iterate an Array in JavaView Instructable »
For this - use "for", not while, you will have one line less.New and recommended approach is to use for each whenever possible.for (int item : array) {System.out.println("One item of the array is: " + item);} Prerequisites are beginner level of understanding Java syntax, but using arrays and loops definitively belongs to beginner level.And use:while (x < array.length) { //print the item x++;}Using this approach you will save one line (you don't have to save length to separate variable) and instead x = x + 1 you can write x++ - much simpler and much more pretty.

Warning: don't use code for Arduino supplied here! This module needs "warm up" period (approx. 1 minute, some sources talks about 2 minutes, 15 seconds is not enough) where it will randomly trigger output. This may confuse everone who is using the module first time!Also the the trigger output takes allways some minimal time (don't remember know, i guess 2 seconds). At this this time it is suitable to suppress checking output state.
- PospaPunk commented on Arbormakes's instructable 4 Ways to Feed Power to an ArduinoView Instructable »
Actually you can use multiple power sources due to 'autoselect' - so you may use USB input as power source and jack together. Read documents.Input 7-12V for jack (or VIN pin) is recommended. But you can use 6 - 20V, again, read official documents and specifications.One very important thing is missing - max. current draw from 5V and 3.3V as power "output". This is important since many enthusiasts use 5V directly to power motors.

- PospaPunk commented on Tech Hunt's instructable Arduino Tutorial - Servo Motor Control With ArduinoView Instructable »
Don't connect servo power to Arduino 5V. Never. separate power supply should be used (at least 5V 250mA, 500-750mA is better). This can reset your Arduino or damage USB port (when powered from computers USB).

How much current can you draw from this case? Some of them are set to only 0.5 Ampers. Also is there some kind of undercurrent protection? (Some of them has auto-shutdown when there's low current draw. It is not suitable for powerinv low power devices like Arduino Nano). But anyway - good job!

Can you post details about axis (shaft) and pipe for shaft and how do you mount it to the motor axis? Where did you get it from? I looked at the video, but it is not clear. I have problems mounting motors, axis and propellers. Do you have any similar projects, where are you also using boat motors, shafts and axis?
