I just don't see some of the data.

I manage MySQL databases. And this was not difficult before. But now I tried many thoughts and ideas how to solve the complexity, but didn't correct the problem. I can't access the amount of data due to the complexity of the program. And I can't understand what to do about it.

Compact ight sensor switch with low voltage

Hi there,I've got a led light that's operated via a magnet, if it doesn't detect a magnetic field it turns on if it does it turns off. It's a led light for car door(check picture for reference) and uses 3x AAA batteries in my case 1.2v x3 (3.6v), if you use regular batteries it's 4.5vBy mistake I've order a tiny light sensor module 3.3-5v(check picture) which obviously can't be used as a switch, not in it's present form. While I'm good with solder, I've build an ebike, I'm a computer guy but when it comes to things like this like this make me feel powerless :( ..I 've used 12v light sensor switches but that's a different topic.So, how can I have a low powered light sensor switch that's compact and can save me from replacing the batteries frequent? ...the led light turns on even at daytime which has no point in doing that. I'd appriciate any help :D

Building Touch Sensors from Scratch?

I am very familiar with velostat and conductive fabric and how to combine them to make textile touch sensors. I would now like to make a touch sensor that's more solid, and made from a firmer resistive substance than velostat. I've been looking up the resistivity/conductivity of different metals here: https://www.thoughtco.com/table-of-electrical-resi.... In theory, as long as one metal (or other material) is more conductive than the other, it should work the same? I've read on silicon and carbon fiber, but I'm not sure if what I'm researching is the solid kind, or the flimsy/squishy/bendy kind.

Gap measurement using a sensor

I want to measure a very tiny gap of about 20-30 microns(0.02-0.03 mm) using a sensor with the help of arduino and then display it using a 16x2 Digital LCD Display. Can someone help me out with the sensor that I will need for this purpose with exact name and its working.The gap that I want to measure is the gap between the the joints of a healing fractured bone.(the joint where the tissues develop to join the broken parts together.)Since this is a leg bone any person walking with such a fractured bone will put pressure on the bone and the gap present in the bone will reduce. So that is what I want to measure using a sensor and arduino. Since this gap will be too small (20-30 microns) I am unable to find a suitable sensor for the same.PS: Main issue I am facing is the measurement of gap using a sensor and arduino since I can find a suitable sensor for the same.Please find the attachments of the bone and the gap I want to measure.Also the thing I am doing is a close case of greenstick fracture. refer to the attachment of greenstick fracture.

Arduino-Based Solar Heater for My Above Ground Pool

A few weeks ago I grabbed the garden hose to top off the pool and noticed how hot the water was as it came out. (the hose had been lying in the sun). So, I decided to put it to good use. We've been looking at solar heaters for the pool but found the prices prohibitive, and being a DIY'er I decided to build my own. I have 50' of black, tangle-free hose coiled on a 2' by 4' piece of Wolmanized, 3/4" plywood. This is perched on top of an 8' 4by4 post which I sunk into the ground near the pool's filter. To feed the hose I installed a faucet in the filter's return line which is under sufficient pressure to travel up and into the hose. The other end comes down to an electric valve before emptying back into the pool. The Arduino portion of the project consists of an Arduino Uno board, a DS18B20 temperature sensor probe, a 12-volt, 3-amp power supply, A small prototype board that holds two 12-volt relays and two 2N3904 transistors which the Arduino triggers, two 12-volt car-type relays which are triggered by the smaller ones, and a Mallory Sonalert. My idea was to have the Arduino monitor the temperature in the return line from the solar hose coil, and when it reaches 80 degrees F, the Sonalert goes off for 5 seconds to warn swimmers that hot water will be coming out of the return spout in the pool. And after the warning sounds, the electric valve then opens for 2 minutes, flushing the warmed water into the pool. Since the system is driven by the pool's filter, the solar hose is replenished during this flush period, and when the valve closes, that new water is then heated, and the whole process starts over. The Arduino code consists of a couple libraries to incorporate and read the temp' probe's output, a subroutine which tests both the Sonalert and the valve when the system is first plugged in, and then the necessary code in the Void Loop section which simply waits for the temp' to reach a preset level and then sound the alert and then open the valve.The system is built into an 8" by 6" electrical box that mounts on the 4 by 4 post just under the solar hose panel.The systems been up and running for about a week now and I've averaged about a 2 degree rise in the pool's water temp' per day.If anyone is interested in seeing photos of the project, or the Arduino code, I'll be happy to provide. UPDATE: Here are some phots of the project...

​Make an optic close focus.

I want to be able to put my night vision monocular in front of my 2x scope on my airsoft.I need a combination of lenses to put between my scope and the NV to let the scope focus at a couple of inches (instead of 30 feet), and reduce magnification because otherwise I’d just be looking at a tiny part of the phosphor screen heavily magnified.I know it’s possible because a commercial unit is available, I just don’t know if it’s feasible for a guy like me (doesn't have a degree in optics) to build (I'm thinking no, but I figured I'd ask).Thanks for any help you can offer.

Arduino heating controller: solar panel, oil burner, stove. NEED HELP AND ADVICE

HI this is my first time with arduino and electronics so please be forgiving.i want to make a controller for my home heating system and if it possible be able to control (change temp. setting, see statistic, etc. by phone - Bluetooth).so, i have three source of heat: solar panels (water), oil burner, wet stove. first part of plan is to connect all electrical components correctly (to make sure nothing blowup), second step is the program. third connect controller with phone by android or have a option to send sms to turn on/off oil burner.let's startthe heating system should looks like that (photo attach)please don't focus on the plumbing (that's only sketch), electronic and programing is more important.program (second step) should do:1. if T5 >T2 pomp P2 work 2. if T3>55'C , P3 work but only if O1 is switch off (automatically P1 and M1 is off, because they will be connect directly to O1 power) 3. option to on/off O1 by click on the phone (or by modul GSM in the future e.g sim800L) 4. additionally options 2 and 3 they are conditioned by other sub-option of 5 zones (where hot waterwill flow, so what will be heat): a)olny hot water in the tank- M3 open, b)only underfoor h.- M2 open, c)only radiators- M4 open, d) all heating, no tank- M2 i M3 open, e) all M2 M3 M4 open. so, before turn on O1 start making fire T3, one of the zone have to be pre-sellect.also if T1 >60st.C (and O1 and P3 are off), P4 will turn on (dump extra hot water to underfloor h.).that's all, nothing more .... but it's to much complicate for me right now. :smiley-confuse: and third part: all should be controll by simple phone app (android) e.g. turn on/off oil burner (maybe timer), change temp. in tank, change zone, see statistics etc.thera are elements what i have already- arduino nano-logging data module-relay 8 ports-bluetooth modul At-09, ble-4.0-extension board nano v3.0- temp. sensors DS18B20 i connect everything by all info what i've found in internet. also i tried to do simulation in THINKERCAD but many of my elements are not exist in the program, stiil no win. i didnt want to connect power just in case of blow off :o this is what i already found online:http://www.reuk.co.uk/wordpress/arduino-solar-water-heating-pump-controller-design-and-code/https://thesolaruniverse.wordpress.com/2016/11/21/monitoring-temperatures-in-floor-heating-loops-with-an-arduino-with-data-display-on-a-3-5-tft-screen/http://house4u.com.ua/articles/solar-controller/en/part11.phphttps://www.instructables.com/id/2nd-Gen-Arduino-Hot-Water-Solar-Collector-Controll/https://forum.arduino.cc/index.php?topic=70048.0and about bluetoothhttps://arduino.stackexchange.com/questions/19517/hc-05-bluetooth-module-inq-command-doesnt-worki only showing the links to proof my hour's spend in google.i think first two are the best.so i put together all what i found and this is my first program:const int TANKSENSORT1 = A0;

How can i get my PC to detect a WIFI signal again?

About 3 weeks ago, I was trying to update from win10 v 1709 to Win 10 version 1803 but I couldn't finish because the signal for this particular WiFi at the Lodge became so weak all of the sudden. Actually, the lodge has two routers- one with the excellent signal and the other with a very weak signal. What surprised me is that my android phone detects the signal immediately I enter the lodge premise but my PC won't. This WIFI network only shows up on the available networks for a few seconds and it disappears for hours. Sometimes I get lucky, it comes on and connects automatically but limited service. So I think my PC has a problem and not the router. Any help please. I'm stuck here for like 3 weeks, school work isn't easy to do anymore. I've atrached pictures from which u will see what Im talking about. I'll appreciate your responses.

Convert airgun/Paintball gun to be fired by a computer (12v solenoid valve)

Hi!I have a project this summer where I need to convert a paintball marker and a co2 Airpistol to be fired by the use of a solenoid valve powered by 12v.The project goal is high-speed photography, more or less photographing object being hit by a projectile.What i need is a way to fire these guns precisely by the use of my computer and software, and since I already have plenty of 12 solenoid valves that work with this system I thought my easiest way is to adapt these valve to trigger the guns one way or another.I just purchased a Valken V-TAC SW-1http://www.valken.com/Marker-V-TAC-BLACKHAWK which I plan to use as base (for parts) My reason for getting this particular one was that it was on sale for 50% and seems to be fairly popular as it's based on the Tippmann 98 design.I attached an image of the valve I used with my controller and software (Cognisys Stop shot) now I can probably use any 12v solenoid valve (with the same spec ?) as the one I use now so it doesn't need to be these exact valves. As long as they can be operated by turning on-off power with the same powersource i use to control my current solenoid valves.From my understanding, most airguns use a pin valve, which is hit by a trigger mechanism that is then rearmed by the blowback.What would be the best way to modify an airgun for my needs? Replace the pin valve with a suitable solenoid i can control instead? Or go for a design that uses maybe use a piston and 2-way valve to hit that pin?The gun does not need to be mobile or ergonomic, it will be placed in a rig regardless, however keeping the barrel and keep the Picatinny is preferred to be able to mount marking aids etc. and mount the gun to a tripod.Any tips or suggestions are highly appreciated!Thank you!

Reformatting bugs

I just published an instructable but I'm dismayed to see the autoformatting has made it look pretty rotten. Steps 2 & 3 have wide aspect ratio images and they have been cropped and rendered in very low quality. The autoplay youtube function (where you can make a youtube video look like a gif) no longer works and the aspect ratio chosen seems to be ignored, so you get the black bars even when you do hit play. Any chance this cropping/breaking can be fixed? Thanks.

Li-ion 5 pin, pinout?

Good Day Fellow TinkerersI have a battery that came out of a Android Tablet that i want to use for another project.It has a cuircuit board attache to the top which i would assume is a over/under charge protector and it has 5 wires coming off of that. 2 x Red, 1 x White and 2 x Black.The two black wires are connected to the same pad on the "protection circuit" and the two red are connected to the same pad. The white wire is on a separate pad i.e. 3 pads, 1 with 2x red, 1 with 2 x black and 1 with 1 x white.I figure the Red would be positive and the Black negative and then i would assume that the white is the Thermistor connection.My Question :How do i connect this externally from the tablet to charge? I figure red and black are the usual, but how do i connect the white wire?Thanks in advance for any help :)

Car phone charger works in a 12v car port but explodes from a 12v DC adapter?

I've got a lighting project that is powered by a 12v power supply and is driven by a 5v arduino. I want to minimize the amount of wiring I run to the project and power the arduino from the 12v power supply. One of the instructables recommended to use a simple car phone charger. 12-24v to 5v. Well I did and the thing exploded. I checked the polarity (bought a few of them) and it's correct, there's also an onboard LED for indicating power on. Thing lights up, works for a second and smoke starts coming from the IC.What is so different between the car 12v and DC adapter 12v?the onbaord IC is ADB85063

Landscape Lighting Electrical Connections?

We are in a newest home (5 years old). We had in-ground wiring installed but no lights. My wife now wants landscape lighting installed.I have two sets of 12 awg wire terminating near an outlet at the rear of the house. One wire was tapped with black electrical tape while the second 12 awg wire had green electrical tape.I found all the wire loops (where they come out of ground)However, I also found a junction box. There are two sets of 12 awg wire into the junction box but nothing is connected (pic attached)I then found a location where two sets of wire terminate. (Pics attached) comes out of ground, does a loop, but there's also an end piece. First I assumed, I had a "loop" system" but the junction box and now these two locations with en end piece of wire is throwing me off. Thoughts? Any suggestions would be helpful.ThanksB

Problems entering a contest

Hello,I have noticed some time ago that when I enter an Instructable into a contest it doesn't work the first time and the instructable isn't listed as an entry even after a few days. I always had to re-enter and then it worked. Now it just doesn't work and that's it. I've entered my latest instructable three times between yesterday and today and nothing. I tried the fourth time now but I wanted to mention this already because there seems to be a problem. My instructable matches the topic 100% so I don't think it has been refused as an entry.

Power outlet controlled by windows driver (not master/slave circuit)

HI, the idea is to control a power outlet when the OS is booting. And even more important, when the OS shuts down. the outlet should turn off before the PC goes in shutdown.A master/slave socket (which i have) only switches off when the PC goes into OFF modes which results in a big bang on my Active Speaker setup. (behringer B2031A with B2092A).So, in short. i need a circuit thats being controlled ON after a driver has been loaded during BOOT.and that cicuit needs to power down when the Driver is being offloaded during shutdown.AC being controlled by a solid state relayThank you for anyone who can helpbest regardsmarco

Husqvarna chainsaw carburetor adjustment tool

I just worked on a Husqvarna 142 chainsaw for a friend. Yes, there are openings in the side of the machine so the Low and High carburetor screws can be adjusted, but a special tool is required, or parts need to be removed from the saw so the screw shanks can be grasped with a pair of needle nose pliers. A special tool is svailable for about $6 US. It fits over the longitudinal ridges on the upper part of the screw shank. I discovered the right size of semi-rigid plastic tubing makes an effective adjustment tool. Just cut a length three or four inches long. Push one end onto the desired screw shank and turn to adjust. The tubing is rigid enough that it does not twist, but turns the screw needing adjustment.
