    Cases chasms and crooks.

    My simple fix with a bit In manufacturing accessories port, probably for the fix I did. Notice the manufacturer port, and the case vent that requires the consumer fix...

    Cases chasms and crooks.

    1. A PSU case adapted to cool an amplifier... 2. I need a solution for butt connecting... 3. The secret here is obviously being able to move things so they will fit...

    Wall Wart voltages.

    So bucking and converting should be my focus with stabile psu's for the everyday test scenarios with devices which use ac- dc, dc-dc, and dc-ac, and I shouldn't worry so much about the actual requirements with exception to thpe ones that stipulate a special application. My take then...match...

    Wall Wart voltages.

    Yes, another idiotic inception.... I would rather be interested in some means by which I could drive a significant amount of devices using a single plug, but, nature does not draw in straight lines. So, when one is to replace a wall wart, and the box full of them does not contain the correct...

    Triac Question

    Obviously the triac that is giving you a bad reading is faulty. Those are the ones I like to test the voltages on... Smoke, too much voltage... No smoke, open connection or fatal error.

    Uneducated question

    Water batons do not dip their op amps in blackwater ponds.... Not around the op amp, but on the line what is supposed to connect to the triangle thingy... (OP amp symbol has a line with a circle at the triangle where the line connects) When these are on a network in regular schematic, they...

    Analogue Meters for Nostalgia Sake

    Eyow... Digital meters cannot measure signal below their threshold accurately. They also do not have the ability to measure transducer freqs without proper accessories. Have you ever seen analog meters dance? Well that used to mean something was terrible wrong. Today if the meter doesn't...

    Uneducated question

    On a schematic or block diagram, if there is a triangle device with lines to it, what in the description of its function does a circle attached to a wire connected to it idealize?

    Sallen Key Low Pass Filter, bandpass filter

    I had so many problems and pass filters, that my theory simply doesn't use them.... At all. The signal is usually checked for changes in a the circuit, correct? Anyway since the signal changes could knock everything out of sync, and freq, I came up with the idea of driving a good standard freq...

    Relay Priority

    Most relays only fire once. They trigger one switch that is open without power. When the relay is closed, the power supply that keeps it closed is usually part of a feedback circuit that doesn't lose continuity unless it is manually disconnected, that is to say, when the relay is powered, it...

    Unknown PSU switch.

    Time for a comedy break! This is all rhetorical non sense so bear with me.... The pics are of a standard design factor for some kind of normal thing folks want. Ok. It has 3 relays 2 5 ohm joules/10watt ohm resistors, a fuse, a transformer a couple of dip chips and 3 ports for what ever it...

    Blind DVD Recorder or Special Remote?

    Anyone on this board have the remote code for the RDR-VX525 which allows a universal replacement remote to be used???

    Blind DVD Recorder or Special Remote?

    At the close of C-Band satellite TV signals, I was really deep into those universal remotes for dish... I had one that ran nearly every device in my toad pad. Anyway, there were codes for nearly all devices. So my home studio has grown as a recourse to losing TV, and I found a cheap Sony DVD...

    Need help finding SMA jack | Noob

    The think here is contact... Your replacement should fit the hole it came out of. What's wrong with the one you are showing us?

    Need help finding new(old) capacitor or equivalent, please

    Use the exact same uf...but higher voltage ..

    please i need a mentor to guide to learn how to make basic electronic circuits especially led emergency lights, mobile phone chargers, laptop chargers

    I always tell everyone who asks things like that... You can learn everything you need to know by learning how to charge a battery.

    LED Lights should we see the Watts or PPFD for Indoor Grow

    I have only seen one thing grow in synthetic light. Very fine moss. If you use LEDs to power a stabilizing system, after the plants get their second and third leaves, it should work, if you don't have any thing else, but where folks usually want instant grow, fast fruiting and robust buds, the...

    Altering sensors of similar sort...

    On Temp Only sensor... sneak trick.... ABC switch hidden in battery compartment... I have a wifi for my arduino if that helps!!!!! back to the spatfomr ad the snuffles..... Heres my dillemna... OK It takes a VB6(visual basic 6 is the program that builds the control surfaces for phone systems)...

    Altering sensors of similar sort...

    Here's the gut pics... whats my changes? 10% 30% or 60% seemslike with these new devices its always considered less than %60% !!!
