Hello! I am Anas Malas, first time poster that lives in the United Arab Emirates. I was born on the 8th of January of 2000 in my home country, Jordan. Currently i am completing my IGCSE with maths, physics, computer, english, chemistry and biology on year 11. I plan to be an electrical engineer.
I love electronics, i like to work on them. recently one of my physics projects surprised my teacher so much that he didnt believe i did it with no help, he said it was the best he has seen in his career as a teacher, that is 27 years long! i like to believe that part of it is that components here are not readily available. what you could find however are knockoffs that cost multiples of 5 that of the original part, such as a 2n2222 transistor that cost 3$ but released some of the industry's most beloved blue tined smoke at 3 volts 18 mA driving an LED on collector with 6 volts feeding a 1 KOhm resistor connected to the base! also in this age salvaging electronics isnt that useful especially with SMD components
As i mentioned, i am studying in year 11 right now, but plan on changing my school to complete my A/As levels because of my hopeless physics teacher, and i would like to give all my friends some sort of a gift just for them to remember me, because there is the possibility of never meeting them again.
I like to do everything that is related with DIY. I know about electronics, about woodworking, about programming(C++, VBasic), about arduino, RC airplanes, and even about glass cutting! i would like to make a wooden enclosure, engrave their names in it, spray paint it, and add LEDs all over it (No more than 15 though)
I have never tried using a microcontroller, so this will be my first project, i have until the end of may to get done with it.
I already ordered some powerbanks in bulk from a Chinese place for 1.5 dollars each (including shipping) which i plan to use for powering the thing, where i would connect the usb output to the circuit in series with a switch, extend the micro usb input out the case for charging. and replacing the little hopeless SMD LEDs with others through transistors to the outer case to show low battery.
one of the problems is that i have no idea about the electrical noise of the powerbank or if it gives a clean 5 volts. I am not even sure that it gives 5 volts as it shuts down each time i try probing it with my multimeter(it does work with usb devices though).... I also do not have an oscilloscope to see the wave form because i can only buy so much with all these hobbies...
For the LEDs, most of them will be independently controlled, but some will be paralleled (for one on the top and a matching one at the bottom), they will be of different current ratings and colors but nothing more than 30 mA. I need to do dimming (possibly by pwm), i am open to multiplexing if it can accomplish what i need although i dont really understand it. but if i could use such a method to make my life easier i sure will learn it.
with all this in mind, what microprocessor would you recommend? but please dont recommend something that is 20$ because i have a limited budget and will have to make about 15 of them.
also i will need to ship them and some quality LEDs from somewhere in the world, i certainly am not going to find anything locally. so if you could recommend any sort of a good website or shop that i could buy from that would be much appreciated. Also about the programming could i use an aduino uno to program the thing? or should i buy a separate programmer? (again, budget)
I know that i just wrote the longest essay you will ever read but i want you to understand exactly what i am doing. please try helping me even if you could just guide me in the correct direction for looking for the parts. the manufacturer websites are rather hard to navigate as i dont know the technicalities of microprocessors that well.
also i am very sorry if a similar post is already present. but i didnt find any. Thank you.
