HI Everyone. I have an idea for making a home made version of a compressor Nebulizer to be used for inhalation at home, the reason behind that is that the commercial one is a little bit cost, So after watching so many videos on the repair of such devices , I came to find that, its working principal just DC motor to drive a fan and what I think as A diaphragm pump, as you can see from this video. the question now is that, there are a small version of a motor connected to a diaphragm pump as you can see from that link Ultra Mini Air Pump Oxygen DC 3V Diaphragm Pump Booster Small Wrist Sphygmomanometer Medical Equipment Pump 0.9W | Makers Electronics is it possible to build a device close to an actual compression nebulizer using the mini air pump in the above link?

Thank you all for your generous Advices , I've already bought the Components and Soon Gonna connect them and tell you about the result should it Succeed, it will be a great new product.

loribennms , thanks sir for your answer . This why I'm Here to discuss such a board. Hi everybody, it seems that I found a better board that is doing exactly what I'm Looking For, please check it here, LM386 Audio Amplifier Module (200 times Audio Amplifier) - RAM Electronics (ram-e-shop.com) and This is the wiring Video, It's also Cheaper. I'd like to know your opinion about it, and in case I'd Like to belt a professional plastic enclosure for it, where to find the right place for designing the enclosure to make a model of parts ready for the injection mold. And If I'd like to run it on AA battery how to calculate the right voltage to run the whole thing, an amplifier board, a mini speaker, and a mic piece.

Sure, next project ideas will be paid for sure, Really you made my day, I'm gonna test and tell you about the results .

Thank You HarryA, Would You Mind, showing me the complete schematic of the sound sensor board connected directly to the speaker and the power supply, as I'm not sure how to do one.

Thanks HarryA For your answer, you mean to connect the LM386 directly to the speaker through using a 220 to 250 microfarad capacitor , and ditching the whole board .

Hi there Everybody. As I'm New to electronics, I need your advice, I have an idea of a project that includes a mic connected to speaker, the point that I have a small audio sensor board the I'd like to connect directly to a speaker through an analog circuit and without the use of an Arduino board, here is link to the chip I own for the moment, Sound Detector - Analog & Digital Outputs - RAM Electronics (ram-e-shop.com) , I hope somebody help me building such ana analog circuit.
