unfortunately, there is no info regarding SJ1. At least, I have found nothing.

Hi W. Basu, thanks. However, as I said it works with 3.0Volts. I just would like to understand if it is reliable. There must be a reason why they made different versions of the board. Maybe earlier the ICs from atmega were different and did not accept a range of voltages.

Hi berkeman, thanks for the fast reply. There is a Linear Voltage Regulator. However, it regulates down only to 5V: https://www.lcsc.com/product-detail/Linear-Voltage-Regulators-LDO_Microchip-Tech-MIC5205-5-0YM5-TR_C70431.html. There are two versions of pro mini: 3.3V and 5V. I definitely have...

Hi guys, I am currently building a small device that is to be powered by a 3.7V battery and is run by an Arduino mini pro 328p 16Mhz microcontroller board. This board is to be powered by a 5V power supply according to the specifications. So I would need to add a step up converter, although I...

Except in "Forrest Gump" ;-)

Hahaha. Nice one.

Damn it. I totally overlooked the obvious. In German, we use to say "den Wald vor lauter Bäumen nicht sehen", which means "you do not see the forrest because of the trees". Of course, the device vibrates. Thanks so much Dave!

Hi guys, I am trying to make sense of an electronic component, but have found nothing on the internet. Does anyone know what this component with the label " R22CC1" is? The half cylinder shaped part ist rotating. Thanks a lot in advance. Bests Andy

Hi SDL, thanks a lot! If I understand correctly, the thickness of the plates does not matter because there is no practical way to charge a parallel plate capacitor even remotely close to its true ability to contain excess electrons, which makes kinda sense since the more electrons are in a...

Thanks a lot, berkeman. I have been here for one day and learned a lot! I have been in some forums before. I am not exaggerating if I say that this is the most active and most competent one I have ever tried. Again: glad to be here!

Hi BiGyElLoWhAt and vanhees71, that was a huge help from both of you. Thank you very much! I understood the formulas. However, I cannot get into my head that the thickness and material (e.g., copper vs alu) of the plates in a parallel plate capacitor do not matter. My logic is that if the...

Hi guys, I am struggling to find the answer on Google and at forums. I am experimenting with two sheets of aluminum foil that are separated by a thin plastic foil. In theorie they should be attracted to each other if I connect one foil to power and other to ground of a DC voltage source. I am...

Hi guys, I am Andy and a hobby tinkerer. I am actually a lawyer but love to develop ICs, software, robots and other stuff. Great to be here!
