Good catch. Our blog version is correct, which shows the proper hole for a top sound port: www.cuidevices.com/blog/comparing-mems-and-electret-condenser-microphones#electret-condenser-microphone-basics

Hi David, we would recommend submitting a ticket with our Ask an Engineer chat and we can help you out from there: www.cuidevices.com/contact

Hello sir, yes we could generate dc output, but remember the efficiency isnt always 100%. I mean you can generate power but it gives a weaker output than you expected. Not efficient in total to generate

Another nitpick, sorry. To help people design - go through the process of picking the heatsink...look at a table and say "we need at least 26 deg/Watt with this surface area and this height limitation, so these will work". The arbitrary HS choice was confusing, especially when the point of the video is the clarify HS choice

Without knowing the specifics of your application, you are probably after what is generally called a "board-to-board connector." However, these come in many different form factors and types depending on your specific design needs. Hope this helps!

@@cuidevices the shear number and type of connectors is one reason for the confusion

@@user-ww2lc1yo9c as we don't currently offer board-to-board connectors, we are not an expert in that field. We would recommend reaching out to a manufacturer that offers those connector types. They would be better equipped to make a recommendation based on your application requirements.

We see what you did there! ;) The recent EU legislation is certainly a good indication of where things are headed.

Maximum current (Imax) and maximum voltage (Vmax) are operating limits, not the module's absolute maximum rated values. Recommended operation is only up to 70% of these limits because operation beyond limits will result in decreased heat absorption and efficiency as Joule heating increases.

@@cuidevices Thank you for the quick reply. Indeed I had bought a TEC2-19006 recently and was running it at it's Imax and Vmax. Recently just started noticing I should be running it at 60-80% (or in what you're saying 70% power) so roughly 16v and instead of 6a, I'll work on running it at 4.2a instead. Thank you. (Just a hobbiest trying to get more into these things as they're pretty neat!) Although I noticed my peltier TEC2-19006 only has a Qmax of 36w, while your website offers some which much much higher Qmax (which my understanding is the higher the number the more it can remove heat from the cold side and transfer it to the hot side) So I'll definitely try to order some very soon from your website.

Glad it was helpful! We appreciate the feedback.

es imparcial te dice los pro y los contra de cada uno, ademas que el diseño esta ligado a las partes a usar, puedes usar un ventilador de manguito muy bueno si lo comparas con uno de rodameintos hecho con bearings chinos, tal cual los autos

CUI Devices actually offers regular sleeve bearing and ball bearing fans in our product portfolio. While we do promote our omniCOOL system as a unique alternative to the two more traditional fan bearing designs, there is always going to be a use case for all three bearing types presented in the video, depending on your application requirements.

You're welcome! Glad you found the video helpful.

ES LO MISMO, SINO QUE EL COJINETE DE rodamiento hidraulico aparte de estar hecho como indican en una m flotacion magnetica q distribuye mejor los esfuerzos y genera menos friccion tiene un analado en forma d eespiral que hace que el aceite en la parte inferior fluya hacia la superior lo que mejora la lubricacion, pero si lo que quieres es un rodamiento a largo plazo aunque sacrifiques el ruido como para uso industrial entonces los ball bearing es tu eleccion, pero si te importa el ruido para una laptop en una oficina, entonces este ultimo es tu eleccion y cambiarlos cada 15,000 horas de uso y asunto arreglado, no haya nada eterno.
