    Safety capacitor for a Singer Sewing Machine

    I am not familiar with your device but im sure there is a good reason they call it "safety" capacitor. P.S. You should have started an other topic about it. WELCOME on board :)

    What to do with all these chips?

    Right. Well the breadboard is always the first step i take after i finish designing a circuit. If it passes the breadboard test then i continue designing the acual PCB.

    What to do with all these chips?

    Thank you Harald. Indeed at the moment i am desperate for a project idea. By the way, sharp vision i see you have :) My name in Hellenic language is Κωνσταντίνος, romanized: Konstantinos also known as Constantine. Either with a K or with C it is correct because in Hellenic language we spell K...

    EP 650 headphones, power button problem

    Well obviously the damaged button has to be replaced. Once the top goes off it can not be re assembled. You need to find the same type of switch and unsolder the old one and solder in the new one.

    What to do with all these chips?

    Good day dear friends, happy Μonday ! Today I am posting something different for a change. Over the past decade many different kinds of boards have fallen into my hands for salvaging chips. Whenever I was in the mood and had enough time I would strip them and list the chips ive removed. I now...

    Help recovering fdd with bad sectors LINUX or Windows

    Good day everyone. I found a box with old floppy disks dating back to 90's and wanted to copy them to my pc. I have a set of windows 3.1 setup disks and one of them has bad sectors (disk 2). I switched to linux debian jessie because windows10 and scandisk does not work with this fdd. So i...

    RF keyfob & arduino.

    Yes i know that arduinos are not rf receivers. they are MCU's. what i ment to say was that i want to use an rf receiver with an arduino

    RF keyfob & arduino.

    Yes ive seen such but i would like the keyfob to transmitt something that will be received by an arduino. The arduino will then tace further action. Something like the one suggested by Harald. https://www.adafruit.com/product/1096

    RF keyfob & arduino.

    That is useful Thanks !

    RF keyfob & arduino.

    As input to the arduino. Not exactly unattended but yes that is for sure. I would like to buy a set (keyfob and receiver) that can work with arduino. I have found arduino to arduino rf tranceivers but thats not wat i need atm. As for my leftover keyfobs most likely not worth the trouble...

    RF keyfob & arduino.

    Well first because i would like to program it to my convenience for example i want to program it to start the motor after a sequence is pressed. Second because maybe in the future i might implement arduino to arduino rf communication.

    RF keyfob & arduino.

    Hello ! I have a small motor that i want to control with an arduino (uno or mega) using an RF keyfob. simple operations like start and stop. Nothing special. I really have no idea about how RF keyfobs can work with arduino. Could someone point me to some rf module and maybe give me some insight...

    No worries brother Harrald, Hellenic (Greek) language is semantic and so complex that no one can blame you :)
