I am just getting into serial communication and was discussing Full Duplex on a single wire with someone, neither of us had a good solution, so no better place that Eng tips to find out whats the story!
Q. Is it possible to have a single wire(not...
Hello
I posted to another forum but probably should have posted here instead now that I am a bit more informed:
Could someone please describe what the concept is for using a shaft encoder on a stepper for tracking with a controller? I want to learn what is the most accurate way to track...
Hello all I have a pretty simple question (I think) for guys that are familiar with steppers and encoders.
I am getting a nema 23 stepper from US digital with an E2 encoder, that will go into either a LS7183 or LS7184 "Encoder to a Counter Interface IC", then output a clock and direction to...
Hello, I am looking for some advice with gluing some metal together with a black epoxy or plastic that will sand nicely, and support heat to 300 degrees in an anodizing vat.
I have a product that requires several pieces of small machined aluminum rectangles to be assembled together with .05...
I went over thiis plan in detail with an Analog Device engineer, and it appears I have the exact same schematic, but somehow this isn't working:
link 1 is my schematic, link 2 is the AD drawing.

Hello all.
I am looking to convert a logic system into a micro based board. From what I have learned about the process, I'd like to use C and write some code on Xcode (OS X), then test it with a USB connection to make some leds turn on and off. I am looking to find a simple chip to start...
Too many vias! Over 500 vias, plus the 30+ chips on a double sided board. Fortunately I have a machine to drill it in under 15 minutes very easily. Running wires through the vias is not fun. I am looking for ideas to "presensitize" the holes, then do some home brew bath for tin (copper, etc)...
I am assuming that a relay is a pretty solid method of switching in a battery on power failure. I am stacking two 12v batteries that have a single 24v charger. I don't like the idea of having the relay on forever powered my the mains, I feel like one day there could be a failure with it. I'd...
If someone could help me get this in the right perspective:
I want to take a digital output ( logic 1 pulse at an adjustable threshold) from the current consumed by an AC servo motor. I have a 24v regulator that is driving the entire motor section, my theory is to insert a current sensing...
I am using a belt driven actuator to move an object clamped to the belt. The motor used is a servo with a controller and no means of outputting torque being applied. Here are my options so far to sense pressure and output a pulse to trigger a stop, reverse, or whatever else. The sensor need...
posted a version of this last night, I don't see it so hopefully it wont be a duplicate post:
What is the best solution for a circuit where you hold two switches for a duration(ie 2 seconds) and a latch gets fliiped via the data input.
My plan is 2 have an AND on the two switches, when both...
I have been researching some products for laminating with 1/4" low iron glass whereas the laminate would be conductive resulting in a touch sensitive product to connect to a circuit for generating a pulse from touching the glass. I have narrowed the possibilities down to stainless or carbon...
I have screwed up two different servo motor controllers somehow. The output called PFIN or position finished is usually 24 volts or nothing, 24 being ON, and nothing being motor in motion. These controllers are a lot of bucks and since now the damaged outputs(open collector pnp) are putting...
Can any one please give a logical answer for this behavior:
Using a 555 with reset(pin 4) going to +V
4.7 mic to GND from pin 6/7(thresh/discharge)
10k to +V off 6/7
Input to the 555 trigger is from an OR gate, and the 555 is normally sitting at LOW in- gives HIGH output Hi in gives...
I am designing a product that uses laminated glass with a yet unknown product between the glass that can simulate a netal surface. I am using touch circuitry, and the material needs to act like metal in the sense that metal works great for touch pads. 1/4" glass over the metal works fine as...
I am trying to find a circuit whereas you touch a piece of stainless steel and generate a 12 volt pulse that is sustained while the pad is being touched. I have circuits for one one touch and timed output, but I can't seem to find a circuit anywhere for what I described. Any help would be...
hello. i am trying to find out if there is any circumstance where an open system containing water or hydraulic fluid does not seek to level itself out.
for example, if there is 4' wide funnel shaped container that has a 4" hose on the bottom that runs up towared the ceiling(higher than the...
hello
i am trying to design a system that will allow me to send an object down an airshaft, and then have that object enter the water without water rushing back in.
for the sake of an easy to understand word picture:
an airshaft is submerged into a body of water for approxiamately 20...
