    Looking to add some notification from a sewer ejector control panel

    Why is this robot forum page dead?

    Lets face it, robotics is mad expensive and you need to know your S*** to even think about adopting this, not so good for amateurs and students who wander their way to ETO. It would be the same as if I showed up asking for help building a doppler radar, in fact im convinced that a radar would be...

    grounding and corrosion

    My greenhouse got a little soggy and rusted a little bit, and i was wondering if i could i use a power supply or somthing to reverse the rust process, would this work? also if i attached the supply to ground which polarity would i connect to the greenhouse to create this effect? Also i got a...

    ChatGPT, anyone use it?

    As good as it is at stringing together words, and as amazing as this tech is, you can really see the limitations to where it really has no idea what it is saying or doing, and just blurting gibberish, also proof that it is far from sentient.

    Code glitch causing reset

    Sounds like the right track, can you get in to that subroutine, and start commenting out there?

    Is it possible to construct circuit to mimic this odd iPhone behavior?

    Also to note, is that I have had cellphone glitches where i have picked up other ppls phone calls, but only brief segments and only one side of the conversation was heard. I had a quick look at how cells work, and basically they use the same frequencies, one for tx and one for rx, and there is...

    Is augmented reality beneficial for business?

    My company is in the test phase of using AR overlays on cell phone to display locate data collected by gps. I have also seen videos where forensics use it to capture crime scenes, and real estate use it to give 3d house tours. but as mentioned it is big and bulkey, and expensive for both host...

    Not sure what happened

    In electrical, there are 2 grounds: one is the neutral which is the one your aware of, which is the circuit ground, it runs down a wire back to the pannel. The other is the chasis ground, which is the third prong on the plug and a wire from it on the inside usually bare copper or green, this...

    Solar tracker

    ok, i now see the errors in my ways, so I have found a new design where i can fix my 2x4's in to a secure vertical position and have more secure latches, but this new plan will require stepper motors. But i run in to the problem again where I need to know the torque of the motor required. I...

    Has anyone had problems with QEI affecting the rest of the CODE?

    Hserout "AZILB=", #azi.LB, " ", "AZIHB=", #azi.HB, CrLf I have seen strings cause mem leaks, I think cos each time it writes somthing like "AZILB=" it has to create a whole new array for each iteration, causing the mem to run out and a overflow, i think they called it a mem leak. the proper...

    Solar tracker

    unfortunately , I dont have the gear to steel work, nor any idea where to get supplies. besides I have made similar wooden shelves that support larger weights so im sure some 2x3 or 2x4 lumber will suffice? It all comes down to the actuator requirements. It is only 24sqft and an extra 3ft on...
