I am trying to help my mom figure out what's wrong with her circuit. I know some electrical theory, but I'm shit at troubleshooting.
If I disconnect the underground cable from the 1st outlet, the 1st outlet reads as being completely normal. But when the underground cable is connected, as is normal, the lights only flicker occasionally; and more to the point, on the 2nd outlet I'm reading 120V hot to ground (okay, that's normal), and 120V NEUTRAL to ground (~0 volts in between hot and neutral). This problem just developed all of the sudden, it was... Comment too long. Click here to view the full text.
>>949218 Did you get 120 neutral to ground with the light switched on or off? A loose neutral could cause flickering, if you measured with the light switch on but the light bulb off you would get 120v neutral to ground because no current was flowing. So that's my guess is a loose connection. Check all the connections.
If you want to check the cable you can rent a proper tester that dumps high voltage through the cable to check insulation resistance as well as conductor impedances etc. Standard electricians kit.
>>949218 Is there a possibility that you rolled wires somewhere? Could be that you have hot switched to ground at the J-box which would give you 120V to the L/N terminals at the outlet. Just speculation.
Can someone recommend me a heavy lifting drone? I have some surveying equipment, it weighs about 7kg and I want to do 30 minutes of surveying per charge. My budget is £3,000. I know this is the /diy/ board but /g/ doesn't know anything about drones so I ask here.
A drone will be too expensive to operate, rent or buy. It's too early in the hype cycle for usable and effective commerical drone applications.
If you're thinking of buying or building a drone and operate it yourself, prepare your anus. CAA, FAA and comparable aviation agencies will rape you. This drone needs to be gas powered and is WAYYYYYYYYYY too heavy to operate legally within a mile of population.
I have two 3d printers (Replicator 2x clones), and I design and print prototypes for my father's company. I bought them specifically for this purpose, but I'm now thinking I could also do other jobs on the side with them to make extra money.
How would you go about advertising yourself (appart of social media) in a way that would reach that specific people who would need your services? This is not limited to 3d printing, any advice about advertising your DIY projects would be useful.
>>947508 First, get a website. Make sure your social media is up-to-date. Your website should go over what you are capable of and often means you will need some sort of demo video of your modeling, live demonstration of your models used in action, and the variety of awesome you can offer.
Then, you need to have a constant contact system that updates the second someone emails or calls you. They need to be able to call, email, or live chat you. You should also have video conferencing available for the larger clients.

Anyone into bone carving? I live in Norway and was thinking of maybe carving some simple jewelry and weapons with runes to offer for sale on various local norse reenactment groups on facebook. The dremel 3000 gold kit looks like it would pay for itself, now I'm looking at other tools. Any tips?
I have some idea of the electronics but my programming knowledge is almost non-existant.
What im doing at this stage is straightforward
i printed out circuits with some very basic signal conditioning (low pass filters) for sensors of physiological signals (PPG, accelerometer, thermistor, etc.) onto a pcb and am going to solder it to I/O port of an arduino uno.
I'll be grabbing data from the arduino's serial port and sending it to a PC via low-power bluetooth... Comment too long. Click here to view the full text.
>>949330 yah easy. >GUI uhh, use one of those microsoft visual programming suites. find the libraries required for getting your serial data and analyzing it. should just be STDIO.h or whatever. get it to print to screen. but before you do that, just write a simple terminal app that just gives you a periodic 1s update of the incoming data printed in plain text to a screen. once you can print that data to a screen then you can just input >> arbitrary output to any app. hell you could...

>>949120 Check /ic/. Krita is a bit unstable under some circumstances but there's good shit to be done with it considering the new animation features in 2.9. Pic related was done in Krita by some french animator.
Jetpacks are a far way off. For full flight the fuel to weight is way off, closest would be the ductfan packs but thats not jets. The jets OP showed wont fly the fuel needed. Not to mention the rules, laws that literally keep us down. Hoverbike just started low untethered flights. Backpack helicopter guy still cant take off. But if your intended to be touching the ground mostly. Mostly? Jet bikes with airbag jumping suspension will soon be an x-games favorite in time.
I'm currently trying to convert my old keyboard into a MIDI guitar pedalboard, but I figured the keys would be too small for my feet so I'm planning to put some washers on top of the keys. But what should i do so that the washer would stay on the keys? Tried superglue but it doesnt work. pic related.
sup, Electronics newbie here trying to design my first regulated DC power supply. Why does my transformer explode when I simulate my circuit in multisim? I have managed to prevent damage to the transformer by placing a high power resistor at 25 Ohms between the output of the bridge rectifier and the capacitor bank, however this causes a large performance decrease. Is there a way to fix this without significantly reducing my output? The transformer should output approx. 24Vrms AC.
I had a similar problem with some other simulation software (livewire). Had a similar setup: transformer -> bridge -> caps -> regul -> caps -> load. For some reason, the bridge diodes keep exploding at the start of the simulation. Never solved the issue with the simulation, but our best guess at that time was that the unloaded caps (at the start of the simulation) were threated as a short circuit, making the diodes blow.
>>949084 They have them for 15 bucks at walmart. Some things just dont make sense to diy. But if you really want to ive seen someone on youtube make one out of those handles old people use in the shower and some metal pipe. Looked like shit but seemed to work pretty well.
Doubt your microwave weighs that much, but two ordinary cross braced brackets should be fine. You want brackets that support 3x the weight of the microwave for the pair since who knows when some mongo (you) is going to drop a turkey on top of it. The ratings are for a static load.
