Halo sir big fan of yours I am from India can u refer me something how I should get start with image processing with Arduino I know Arduino basics and little python too any book or s
Nice Video and like to see more of this mailbags. I like the idea of that fire extinguisher for Seon. At the moment I am searching for a solution to secure my 3D Printer in case of fire. But I don’t wand to put it into an enclosure so this co2 extinguisher won’t work. But maybe you’ll have another idea?
A word of caution about these cheap no name tantalum capacitors from China - I used them in a project but they kept blowing even though I was below rated voltage(16V rated caps with 12V across the terminals). About those extremely high capacity ceramic ones - I too ordered them and they go upto 100uF in 1206 package(measured capacitance was in 60-80uF range). I haven't gotten a chance to use them in a project yet so cannot say how reliable they are. At least they shouldn't blow up like those tantalum ones. One thing I noticed was that each capacitor in a strip has slightly different brown-greenish tint to it. In my understanding high capacity MLCC caps tend to be dark in color so that 's alright but the variation in color seems to indicate that these could be rejected ones or proper ones that were manufactured with very loose tolerance. Nowadays I mostly prefer to buy components from LCSC. They tend to be not as cheap as these Aliexpress ones but according to their reputation I think they sell genuine parts.
good hint thanks! I'll use the genuine ones for the boards I'll sell of give away. I'll perform tests on the other ones. the maximum I'll be running them on will be 5 or 3.3V
I'll PM you as soon as you can tell me, do they have crystal oscillator on them or small resonator. I use them for the parts, to make Moteino. Maybe that would be something you would be interested in? I have few blank PCBs I need Pro mini's to be like store-cdn.arduino.cc/usa/catalog/product/cache/1/image/520x330/604a3538c15e081937dbfbd20aa60aad/e/0/e000025_featured.jpg and not like ae01.alicdn.com/kf/HTB13i2IMpXXXXcrXXXXq6xXFXXXU/Pro-Mini-ATmega168-5V-16MHz-Compatible-for-Arduino-Pro-Mini.jpg_640x640.jpg Which ones do you have?
If you need a link to a specific part from the video just tell me. takes too long to put all links in.

Remember that when you apply voltage to those ceramic capacitors, they will no longer be 28uF
congrats
You don't need pro minis? I do :D

Which ones do you have?
Were you able to check?
