    Old Chart for newbie hackers!

    I think most of us have seen this chart before. Word is, it was carved into the tree that Adam and Eve got that apple from. Posting it here was a darned good idea, as it's a great find for somebody who hasn't seen it before.

    Absorption detector.

    Sounds to me like maybe you should be checking into a pressure sensor of some type. The pressure on the sensor would increase when the water turns to ice, if in the proper sensor pressure range, it should also indicate your volume and pressure changes between the water state of liquid or solid...

    Help with signal leaking to power input

    Sorry this is hard to do in your location. I'm betting you're right that it's the board. Only other thing I can think of is the fact that the ECU gets its information from all of the sensors on the vehicle, and if one of those sensors is supplying a bad signal to the ECU, the ECU may be sending...

    Help with signal leaking to power input

    Unfortunately, this could be anything if a diode or cap bit the dust. I don't know if this is your own car, or you're working in a shop. About now, I'd be trying to find somebody who has one of these boards, borrow it, and find out if it actually IS the board. You're convinced it is, and it may...

    Insignia TV won't turn on

    It would probably help us to help you if you list the model number on the back of the TV, maybe we can find a schematic for it to give you an idea of where to look. The most obvious thing we'd check first however, are any fuses inside the television. Unplug the set from the wall. Look inside...

    Absorption detector.

    I'm unsure of what it is you're trying to do. What exactly do you mean by 'detect the physical state of water'? Are you looking for contamination, or specific contamination of some type? Mineral or biological, or both? Clarity of the water sample physically? What exactly is your application?

    School technology project difficulty

    Your teacher's idea was a good solution. Are you saying that you don't know how to build what he told you that you should try? What's the possibility of just using two 9V batteries in parallel to increase your current flow to drive the solenoid?

    8 Year old Introduction to Electronics

    Did you check into any pre-assembled kits for kids to learn electronics? You'd have something that would be a good starting point, and could add to it later if his interest continues.

    Metal detector

    Google is your friend (a quote I've heard from the Moderators here repeatedly)

    New apartment getting shocked on light switch screws.

    I experienced a similar problem years ago. My fix may not be what you wanted to hear. The combination of my socks on the type of carpeting caused a large static build-up and I too was zapped when I touched the (grounded) light-switch plate (they were metal back then, just your screws are now)...

    Wireless intercom for a disabled person

    I'm with davenn on this. Install a key card reader or even a simple keyless push-button door lock/unlock entry system. Try a local locksmith for a system that will work for this situation.

    dakota 2001 TPS

    Congratulations on making things better than they were. With all the new fancy electronics going into vehicles these days, I'm not surprised some auto-MECHANICS are stumped about how to deal with electronic problems. Looks like the way to go, is to cruise the internet for specific vehicles, and...

    Help with signal leaking to power input

    Not a part of your question, but after reading your post, thought I'd mention something that might be helpful. I have not heard of this particular problem, as often as you experience it. My initial thought, is to take a good look at the connector to this assembly, and make sure your connections...

    Help to identify devices by photos

    5. Temperature, and sometimes Humidity chart recorder 16. Might be a Graphic Equalizer of some sort. It would help if we could see the faceplates of some of these devices (not to mention it identification plates). If I were you, and you don't get all the answers here, you might try surfing...

    Do you have a picture of it you can show us?

    Need Datasheet for New Product Engineering P/N 812-203 (relay?)

    You're right, I can't see any detail in your pictures, you might want to try again. Are you SURE this was a company called 'New Product Engineering'?, and not some prototype of some known manufacturer? What did they come out of? Or are they just loose in your parts bin? It would help if we...

    Ammeter Tester

    I'm not into Arduino, hopefully somebody will help you with this in a following post. What prompts my response is my experience with ammeters in your application. MANY times I've found the shunt itself takes the brunt of abuse. It heats-up, and changes resistance values. I speculate that you...

    VHF telemetry repotting

    Considering the fact that these are presumably used outdoors, when you change batteries, I'd clean the battery contact points to make sure the batteries make good electrical contact.

    Removing components connected to large metal planes

    I'd do what you're doing, just reheat the exiting solder and pull the pin. I don't know how often you'd use it, but they do make (relatively expensive) vacuum pump desoldering stations. As for lifting the pads, I'd back the heat off some and be patient waiting for the solder to liquefy so you...

    Waterproofing A Remote Control

    Did you check with the manufacturer, to see if they make a 'waterproof' version of that remote? That way there's a warranty on it.
