Im glad to hear im not just "cheap". Haha. Its not like i dont buy components from time to time but i just enjoy the teardown. Reverse engineering in a way. Everything i tear down gives me new perspective when building something new. I am trying to build something useful right now. Hope it turns...
Hi all,
I often use components pulled from pcbs not in use. When something breaks or I find broken electronics, i disassemble it, salvage what i can and scrap the rest. I havent had much bad luck with it so far. Does anyone else do this?
I guess i should experiment a little. Assembly is one i want to know for sure. I guess i was wondering if arduino was a good starter mc. Lets say i wanted to include one in an motion alarm and i wanted to store the times the alarm is triggered and make them accessible via usb.
Well i guess i need to do more research but please, all opinions are welcome. One of the reasons i joined the forum is to gain some perspective and learn all i can
;) I find alot of good information comes out of debate. Yes i know assembly is a very low level language but i feel it could be very useful somehow. I think i might study both c and assembly side by side.
I want to start getting into microcontrollers. Where is a good place to start? Arduino? And what are some useful languages to know? Ive already started on assembly.
I need to increase the voltage in the motion alarm circuit im working on. Im puting roughly 12vdc into the PIR sensor, but it only puts out 3.3vdc. The problem is that the voltage leaving the sensor is going to a 12v coil relay....ive explored the idea of a transistor or MOSFET. Are there any...
Not as much as i would like. Im a quick study though i started looking into it last night. Yeah i thought it was a stretch to be able to store it. Oh well im starting with a small alarm circuit i saw.
I feel like im on here all the time haha. Im learning to "walk before i run" so i had an idea for a small project. A motion alarm system. Triggered by someone entering a room. I think a PIR sensor would work. Heres my question...i want the alarm to be a speaker but more like an alarm clock tone...
Controlled voltage is my goal. Id like to keep amperage constant. However you and others bring up good points. I think i need to do more studying. Im not ready to abandon this project but doing some simpler projects and getting more experience is never a bad idea. Do you have some good...
Hmm. What if i find a rheostat rated for the power im using? I had thought about the overcharging issue. I am thinking of a way to fix that. Any suggestions?
As far as battery chemistry i know very little. I will study up on that. Thanks
Ok ive drawn up this this schematic to the best of my knowledge. Its taken a couple days of research and im ready for you guys to completely tear it apart haha. Listen im not an expert. But i want to learn so i hope to only(mostly) get educational criticism. Im not starting the build until im...
This is purely an idea for a project. There is no immediate need for it. Im just exploring electronics. After studying theory for a while then experimenting on my breadboard, i figured it was time to try and design/build something. I
I had an idea of a battery charger that charge 12v all the...
