433MHz/315MHz remote controls are everywhere around us, used to control devices such as turning ON/OFF the lights or a TV, or in applications such as opening/closing parking or villa entrance, … etc. Such remotes are available in the market in various shapes and sizes; however, most are equipped...
Proper thermal dissipation is an essential rule for nowadays electronics. The best operating temperature for the electronic components is 25 degrees (standard room temperature). Thermal dissipation in some commercial devices is not done properly which affects the lifetime and performance of the...
Hello all, this is one of my first electronic schematics and I'm trying to make sure everything looks good (electrically) before I order board and components. Another set of eyes on this to criticize and give constructive feedback would be great and point out any issues or mistakes my circuit...
So I bought a 1986 Ford ranger that needed the body harness completely rebuilt . As I'm ripping out the old harness I noticed something that looks like a wire nut with about 6 wires inside of it. Has anyone seen anything like this? Was this Normal for fords back then ? Or was this the result of...
Hello everyone,
I resigned a few months ago and transfer the industry. I have already learned the basics of circuit, 8051 microcontroller, I contact proteus a few days ago, and now I am using it to make PCB. I am currently blocked on the schematic.
I want DIY a learning board, it will include...
Hello
I want to make an auto relay timer circuit such that it turns on the load connected to the relay for 2 min then turns off for 10 min and repeats this cycle indefinitely.
I have a few 555 timer lying around was hoping if could make something out of it. The timings doesn't needs to be...
I'm looking at a circuit diagram for an Omnichord, it seems pretty easy to follow but I have 2 component symbols that I can't figure out what they are. any help is appreciated :)
(Its the dotted line and ladder symbols)
Hi forum.
Have an switch with 12 connections, and there is 7 possible positions. It is taken from a small substation and had being used on the analog voltmeter to switch between meassuring L1-L2, L2-L3, L3-L1, L1-N, L2-N, L3-N and 0 (no connections between any poles).
It is pretty much the same...
Hello! has anyone seen this before? https://www.learningelectronics.net/circuits/4-channel-portable-audio-mixer.html
Looks like a really cool project and I was wondering if anyone has seen/ built it before. If so, I could defiantly use some tips/ pointers.
Sorry if this thread is off topic or...
Newbie Alert!
I have a fairly simple schematic for Bob Beck's plant growth stimulator.
I bought some 6 x 7cms prototyping board (with simple row and column copper padded holes matrix) and now have all the electronic components that I need to complete construction.
I have looked at several...
Built an Intel 8085 microprocessor based project Chess Clock.
Designed its schematic by means of Eagle software.
Used Oshonsoft for coding the assembly language code.
