Wanted: Someone to setup HomeAssistant for my house

I bought a bunch of Sonoff basics and a Raspi 3 thinking it would be easy to build a home automation system out of this.  I was going to use HomeAssistant.io and my android phone, weekend project, no big. That was 9 months ago and I still just have a pile of Sonoff switches and a kinda booting Raspberry Pi 3. I'm so out of my depth, I don't know what part of it is or isn't working, or if it's just not configured correctly, etc.  I need someone to either walk me through this or give me a bunch of files to download and instructions on how to flash the devices.   Name your price and what you can deliver.

Murphy/Wall Bed Over Couch

I am looking to get or make a forward facing full sized make bed that would flip up over a couch.  I see https://murphybeddepot.com/products/next-bed-free-shipping-to-cont-48-u-s-states, and also https://www.youtube.com/watch?v=9-rwAUR14Z8. I like the idea of a couch, and like the simplicity of flip up/down "next bed" - where there's no frame around the bed. Does anyone know of any plans or where I can make or get a reasonably-priced "flip up bed over couch" like that?

Powering car LEDs via USB

Hi guys, I've always wanted to make my car (my parents car :'c ) a little bit more fun, It's a 10/11 year old ford fiesta without Bluetooth/USB. Here's what I would like to do, just wondering if anybody can see any problems with this. I know very little about power or how electronics work. I want to be able to skip songs and answer calls without having to pick up my phone, for that I am going to buy this: https://www.amazon.co.uk/gp/product/B01E3UC59Q/ref=ox_sc_act_title_2?ie=UTF8&psc;=1∣=AP087GSGD7Y0R Now this will use my cigarette lighter for power which is fine until I get to my next part. I also wanted to put LED strips under each of the seats, and for that I would buy this: https://www.amazon.co.uk/Possbay-Interior-Atmosphere-Decoration-Sound-activated/dp/B017VSY3RY/ref=sr_1_3?ie=UTF8&qid;=1477573217&sr;=8-3&keywords;=car+accessories As you can see, that also requires the use of the cigarette lighter. What I want to do to get around the problem is buy this "1M USB DC 5V To DC 9V 12V" cable and also plug that into one of the USB slots: https://www.amazon.co.uk/2-1mm-Module-Converter-Barrel-Connector/dp/B01G56J4I6/ref=sr_1_2?ie=UTF8&qid;=1477573430&sr;=8-2&keywords;=usb+5v+to+12v. Do you reckon this is possible? Are there any obvious problems with what I'm trying to do that I may have missed/not be aware of? Thanks!! Tim Clark

Need help to create a DIY USB monitor

Hi all, I am working on a project to create my own portable usb monitor (eg. ltn101nt02) and a LCD controller board.  However, the controller board requires a 12v power input with more than 2A. I am thinking of using a boost converter but I'm not sure if it will work. Also, with the USB as power input, can it still work as a screen input for my monitor? Can anyone advise if i can modify the board such that I can use a USB for both power input and screen input? Thanks!

Two-way hinges

My wife and I bought an 80s designed house that's not that well designed. We keep one of the litter boxes for our cats in the garage, which is accessed from the inside through the laundry room; and we want to install cat doors so our aging felines can pass through the doors easily to get to it, while keeping the draft from the garage out of the family room. The interior door (between family and laundry rooms) is a standard hollow core and the exterior door (between laundry and garage) is fire code rated solid wood door.  We tried a standard top-hinged door with the cats already, at our old apartment, and the cats didn't take to it, so we we're hoping to do french doors, since they know how to get through normal doors pretty well. But we're kinda stuck on our lack of knowledge about hinge designs; we need hinges that swing both ways. Has anyone out there successfully completed such a design/installation and would be willing to share pics and secrets?

Turn my Raspberry Pi 0W into a bluetooth HID gamepad

Hello there ! I've been trying to get through this for weeks... many projects are quite similar but I have never found one that answers my problem. As the title says, I want to turn my Raspeberry Pi 0 W into a bluetooth HID gamepad. I figured out that another way is possible. Indeed you can create your own bluetooth HID device with either the Adafruit BlueFruit Ez-Key or a the RN-42 module (or even the HC-05 with the RN-42 firmware). But I want neither of these solutions. I want to use my Raspberry Pi 0 W in a way that it will be recognized as a bluetooth gamepad. Creating the gamepad is fine, I used the GPIO of the Pi for the inputs. But once the gamepad is physically done, how to make my Pi appear as a gamepad ? I've seen that you can use hciconfig in the terminal of Raspbian in order to change the class of the Pi and set it as a gamepad but I must admit that I didn't understand everything. And it's important that it appears as a gamepad and not as a keyboard. In a nutshell, I would like to turn my old wired nes controller in a bluetooth one, and play on another Pi where Recalbox is installed. (That's why you must appear as a gamepad and not as a keyboard, because Recalbox only works with bluetooth gamepads). Thank you in advance if someone takes his time to help me with this because I can't take it anymore haha !

Help requested for purchase of components

Hi. I'm a newbie to embedding but I have a project that needs this and there is no commercially available solution that I can find so I need to learn how to build it myself. This can and will be done in modules... I figure I can tackle one task at a time until I end up with a complete working system, but use the system in the meant time, as I get it completed. The main goal is for an electric motorcycle conversion dashboard,  which will include a password protected relay switch "ignition key" to power the vehicle on securely (Task #1), a user configurable display to show speedometer, odometer, tripometer, clock, battery pack voltage, motor rpm/temp, controller temp, coolant temp, etc via a waterproof rugged tablet (probably a Windows 10 tablet, probably with an Android emulator installed). I'm finding that there are so many different options available, I don't know what to purchase. I want to spend my hard earned money wisely and just buy what I need the first time. Instead of learning the "hard" way, I want to learn the "smart" way. Please help me get started. Thank you in advance!

Charging SLAs from DC

Hi Instructables community! I am building a K9 robot - one that is going to be covered in solar cells-in such a way that I get a voltage / current ratio of a pretty high number. I plan to charge my SLA partially via these cells so I can lengthen the space between charges. Unfortunately, my 6V 4.5Ah SLA battery is charged via a plugin adapter and I do not wish to pull it apart unless there is no other choice - so is there are a way I can charge my battery from a constant DC voltage? If so, do any of you know what voltage/currents I'd need to feed it? I can get most any current/voltage specs via transistors and voltage boosters - just I don't know the equation. Thanks for all your help! Jonathan Davis NitroJon Labs

Need help with a wiring diagram for a on/off/on switch parallel/serial battery

Ok I'm not really electronic savvy but I can solder and follow a diagram. This is what I want to do: I have a toy four wheeler for my kids. Has one battery and a push button that makes it go. When you release the button it stops.  I want to add another battery and push button so when you push the original button the batteries run in parallel. The speed will run the same as with the one battery but twice the run time. (please correct me here if I'm wrong) When you push the the new added button at the same time as the original button it will switch to running the batteries in series so it will be faster running on twice the volts. So i'm figuring I need some sort of on/off/on 6 pin switch and a push button switch but not sure how to wire it exactly. Found this which gets me close but I want to add in the push button switch to make it work instead of the toggle switch.  https://www.instructables.com/id/SIMPLE-ParallelSeries-Select-Switch/ The original button is on the handle and you push it with your thumb. I will add the new switch on the other handle. Something like this https://www.ebay.com/itm/5x-Red-Square-Pre-Wired-Momentary-Push-Button-Switch-Reset-1-2-AC-250V-Car-12V/182680718419?epid=11005923516&hash;=item2a889e8c53:g:YoMAAOSwr9VZwoA7 Any thoughts on this would be awesome!

I just connected the + and - of laptop adapter to the cordless drill, BUT it do not want to turn and ONLY MOVE SEQUENCE (move-stop-move-stop-move-stop....). Its move is so strange for me, it's like pulse voltage because the drill just move for a moment then its stop, then its move and stop and always like that... I don't know is it DC or AC, and I've try to make circuit to make its voltage become DC using 4 diode and capasitor, But the result is same (move-stop-move-stop...). Then, I try to connecting the cable adapter to the drill and then pull off and connecting again with rapid sequence. Then the drill want to turn fastly... Please Help me, how to solve this, i need this adapter work for my cordless drill....

MODpreFAB

muddywaters asked a question seeking cheap, possibly DIY, home building. There are lots of great answers to that post; some of the most interesting mentioning prefab and shipping container structures. I recently had reason to read Phoenix, AZ's main newspaper, which had an article entitled “Rehabbing PreFab”, discussing a local project at Taliesin West architecture school. Students are exploring the PreFabricated homes, with Modern architecture styling. Definitely a new take on PreFab. Exciting work, particularly the shipping container mod-mods. Doing a quick search turns up the website busyboo which has many articles regarding contemporary exploration of highly artistic PreFab units. The price of these designs is quite different from traditional prefab homes, partly a reflection of the limited market and partly the cache styling. What do y'all think?  Borrowing design ideas from these MODpreFAB companies, perhaps a DIY opportunity! $$$ Only fools buy retail $$ wholesale $ Those who can, DIY!

Convert AAA battery power to 12V jack?

So I figured out a really good option for my external rumble pack I want to make, I see these Wii lightguns use X2 AAA batteries and have a micro switch that engages the internal rumble motor on the handle of the gun. The batteries are connected to a microswitch and the switch is pressed after the trigger is physically pulled. How can I convert the AAA batteries power method into an external 12V power connector for continuous use and stronger motor vibrations etc? Like I said this is my first DIY thing. I want the AAA battery method to be converted to a stronger more capable 12V. I plan on buying some strong force feedback motors that need 12V. Eventually adding a small Solenoid too.

I should add that I want this pack to be powered by a wall adapter and cable. 12V I am thinking. Recoil and hard hitting rumble will need juice. I can find a way to affix the device. I just need to know what parts I need, and how to wire it all up. I know I need a switch that can be physically connected in way that a trigger pull will engage the motors. I know I need help. Please any help would be appreciated. I also would like to use "solenoids" or "Actuators" I just need to know from more experienced builders what would be better for an external universal type "pack".

Hi This is Eabul. i want to save data to eeprom from press button . when TemperatureUp button press. increase float data like as 0.01> 0.02--------30.10> 30.61 and this value save to eeprom. and when TemperatureDown button press . decrease float data like as 30.60>30.59-----29.10 and update minus value eeprom and increase and decrease valud view lcd display . but when press button save int number not float. and show me lcd display int value. please help how to write and read float value from eeprom. press button. hear my code. //For Display #include // 3wire display LiquidCrystal595 lcd(4, 3, 2); // DS, ST_CP, SH_CP //For time #include #include RTC_DS1307 RTC; //for humidity #include "DHT.h" DHT dht; //for stor tempereratur and humidity #include int SetHumidity; int HumidityUp = 10; // switch up is at pin 10 int HumidityDown = 11; // switch down is at pin 11 float fix = 0.01; float settemp; // make a variable called temp float TemperatureUp = 12; // switch up is at pin 12 float TemperatureDown = 13; // switch down is at pin 13 //result view int led = 0; // led is at pin 0 void setup() { //For timer Wire.begin(); RTC.begin(); //For welcome screen lcd.begin(16,4); lcd.setCursor(0,0); lcd.print("Welcome Elab"); delay(2000); lcd.clear(); //for dht-11 pin setup dht.setup(A1); // data pin 2 } void loop() { //For tempererature up / down float temp[3]; getTemp(temp); float tempererature = temp[1]; settemp = EEPROM.read(1); // read the settemp on the eeprom if(digitalRead(TemperatureUp) == 1 ) { settemp+=fix; settemp++; EEPROM.write (1, settemp); /* write the most recent settemp in eeprom data stoage*/ } else {} if(digitalRead (TemperatureDown) == 1) { settemp -= fix; settemp--; EEPROM.write (1, settemp); /* write the most recent settemp in eeprom data stoage*/ } if (tempererature >= settemp) { digitalWrite (led, 1); } else { digitalWrite (led, 0);} //else { }; lcd.setCursor(0,0); lcd.print("T:"); lcd.print(tempererature); lcd.setCursor(8,0); lcd.print ("ST"); lcd.print (settemp); lcd.print((char)223); //End tempererature controll //For humidity up / down SetHumidity = EEPROM.read(2); int humidity = dht.getHumidity(); if(digitalRead(HumidityUp ) == 0 ) {SetHumidity++ ; } // add one to the settemp else {} if(digitalRead (HumidityDown) == 0) { SetHumidity--; } // Reduse settemp else { }; lcd.setCursor (0, 1); lcd.print ("CH:"); lcd.print (humidity); lcd.print ("%"); lcd.setCursor (8, 1); lcd.print ("SH:"); lcd.print (SetHumidity); lcd.print ("%"); delay (1); // wait 100 milliseconds EEPROM.write (2, SetHumidity); /* write the most recent settemp in eeprom data stoage*/ //End tempererature controll controll } //analog temperature void getTemp(float * t) { const int analogPin = 0; // replace 0 with analog pin const float invBeta = 1.00 / 3380.00; // replace "Beta" with beta of thermistor const float adcMax = 1023.00; const float invT0 = 1.00 / 298.15; // room temp in Kelvin int adcVal, i, numSamples = 5; float K, C, F; adcVal = 0; for (i = 0; i < numSamples; i++) { adcVal = adcVal + analogRead(analogPin); delay(100); } adcVal = adcVal/5; K = 1.00 / (invT0 + invBeta*(log ( adcMax / (float) adcVal - 1.00))); C = K - 273.15; // convert to Celsius F = ((9.0*C)/5.00) + 32.00; // convert to Fahrenheit t[0] = K; t[1] = C; t[2] = F; return; }

Reset password not working

I recently received a temp password for my account, and now that I am logged in and trying to change it to a new one of my own, I am running into a problem. When I enter the temp pass in the 'old password' window one, I get an error message saying "wrong password" I know the temp passes are often limited in functionality to a short time window, so am hoping for a rapid reply & help on this problem.  Mary
