    Vehicle sensor device

    When I park my front end loader at work I need to be far enough back inside the building so the over head door can close. I went the simple route of hanging a string with a tennis ball attached but other large trucks when driving thru catch & tear that off. I'd like to believe there is a...

    detecting shaft rotation

    I'd like a simple & inexpensive method of detecting when a shaft is rotating . This needs to trigger a relay that in turns turns an indicator light on. I have access to the shaft end...but need a method to read and convert this for my indicator light.

    connecting the IDEC RTE-P11-AC120V

    I have an IDEC timer as well as the paper work for it...I just can't figure out how to connect things to make happen what I want to happen. When I leave my barn/shop after dark I want the outdoor flood to come on for the time I set the timer for. This gives me light so I can walk to the house. I...

    testing capacitors

    I recently bought a Southwire testor so I had something to check small capacitors with. On some units I get a OL reading...the manual does not address this reading. Anyone know what/why this is?

    Schematics for Soundolier GPS 610

    I am trying to trouble shoot this unit which is a sound generator. I have no schematics to give me a break down on the various components of these . Anyone able to help me out?

    turn LED on at dark/off during day

    There has to be a 'simple' method on turning a LED on at night and off during the day, without me manually turning a switch on and off. Thinking a light sensitive eye to detect daylight...but after that...what do I need?

    unknown LED specs

    I have a collection of various LED units I have no specs on. What is a 'safe/typical' resistor to use with them? Power supply could be anywhere from 3 to 9v...

    shaft rotation detector

    Is there some 'simple' device I can put together that will detect a shaft once it starts turning? I need it to trigger an indicator light that lets me know a conveyor belt is running.

    choosing correct resistor for LED

    I followed the tutorial link above and read thru what should be simple understandable language...but I'm stuck on de-ciphering the basics. I picked up a Radio SHack #276-0036 5mm blinking red LED. Package lists absolute ratings as supply voltage 5VDC forward current 80 mA reverse voltage...

    what is a Norstat Ku-band

    I figure someone here can tell me what a Norstat Ku-band LNB 4508A is used for...and if I can put it to use myself in any way.

    making an LED blink

    I am thinking of building a 'fake' camera, and want to have a red LED to blink on/off....Frequency of blinking is not critical..Is there a simple method of doing this?

    Infra red light info

    Any one point me a the basics on infared lights? I have a boatload on a circuit board here...wondering what I might be able to use them for. How do they differ among themselves as far as size....power needs...etc. One size fits all?

    resistor replacement

    Neighbor threw away a hand held LED work lamp. Said it died soon after he bought it. I tore it apart and discovered a brown/burnt spot on the backside of the circuit board which had a resistor on the other side. It's hard to make out the colors exactly but appeared to be Brown,Brown,Brown w...

    driving 7 segment LED

    I am a total novice at electronics so bear with me. All the digital clocks I've looked at online are very $$ which got me to thinking...Why couldn't I take any 'old' clock radio unit and buy my own large 7 segment LED and build my own clock? Replace the original LED display with my large ones...

    low to high impedance box

    A total newbie here when it comes to figuring out a means of building a circuit that allows me to connect an electronic keyboard to a mic line input. I'm sure something maybe in the line of a DI box might be the direction I take, but isn't there a simple circuit I can build in a small project...

    power cord orientation?

    I have a reel to reel deck with no power cord.(Pioneer RT-1020H) I have plenty of old cords available to me, but I do not know if I need to be concerned with which way plug it in. Do I need to be concerned with which side of the recep in the deck the common /hot go to?
