See the image in Step 3. The image shows the connections as labeled on the bottom or side of the button and how those wires connect to the pi. I don't have the breadboard setup any more.

I would suggest ensuring that the pins are wired correctly first. Sometimes a pin can "burn out" if not used correctly. Any GPIO pins can be used. So, if not working try another.The GPIO commands can be run from the command line.For example, $ gpio readall shows the state of all gpio pinsHere is a more complete description of how to use the GPIO pins:http://www.embeddedpi.com/documentation/gpio/mypi-...

Streaming video uses much less than 100Mbps (10-20Mbps per tuner). So, it wasn't the USB tuner or Ethernet not being able to handle the bit rate. In my setup, a tuner is only tuned to one channel at a time. In the US, over-the-air TV using ATSC is sent at HD resolution of 720p.My assumption was the RPI CPU couldn't keep up. However, I have no data to support that conclusion. 1 or 2 tuners worked fine, but as I added more it "broke", in that, the tv channel did not play clearly or without interruption. Moving to a higher-performing CPU resolved the issue.Yes, I have spent a lot more money on my projects than is justifiable. In general, you won't save money or time building your own system. I do it because it is fun and educational (or frustrating). I bought and returned multiple …

That sounds like a great Idea.Buy one and measure it. Your channels, resolution, etc. are going to drive CPU usage. My first build was on a Raspberry Pi 3B+. And the RPi could not handle 4 tuners.My Intel based desktop is unlikely to translate to a router's CPU. The hard part with tuners is finding the driver that will run on your system. I ended up talking with some very helpful people at Hauppauge.Good luck! I hope to hear how your measurements go.

So, I played around a lot with this. The easiest way is to just hook it up to 3v gpio and ground. The fan runs all the time. If you don't have a resistor, then the GPIO pins have an internal resistor, and you can try that. The reason for a resistor is all explained in step 2. I am not sure I can explain it any better by repeating the above.Are you using the transistor?If this is too complicated, then try this: https://sites.google.com/site/cartwrightraspberryp...

When I wrote this instructable 3+ years ago, I don't remember shinken being available via pypi, and I don't think pypi came installed.My pip install of shinken (Step 6) is probably causing the problems. (Run $ pip uninstall shinken)Instead of my instructions, you might want to try these instructions: https://pypi.org/project/Shinken/
- jeff.cartwright.562 commented on jeff.cartwright.562's instructable Install and Setup Shinken Network Monitor on Raspberry Pi
... someone else was having this problemTry $ sudo shinken-2.4.3 --init
Well, something must have gone wrong.If you did Step 6 and installed shinken and it started running, then shinken is installed.My guess is some error should appear when you run this command:sudo pip install shinken This must have failed. Try it again and let me know what you see.

I am sorry, I do not know the answer to your question. The doorbell with no circuit works because the push button closes a circuit in the garage door opener sending a small positive voltage.#1 Guess) I am not sure if doing it in parallel would work, because your circuit board may be sending more than just a momentary short. Perhaps, it is sending some type of command.#2 Guess) The circuit board may receiving signals from your remote, and the circuit board is sending the positive voltage to the garage door opener. Then it might work. To make it work, I think you would have to insert the relay connections between the circuit board and the garage door opener. You may want to insert a diode on the positive line to the circuit board so no current flows back into the board. You would want the e…

RPi 3 B+ has built in Wi-FI and should be able to play OTA TV in another room. Some of my TVs use Kodi and Wi-Fi.I run these on Roku: Netflix, Amazon Prime, Hulu, YouTube, ... I tried many tutorials and could never get these to run on Raspberry Pi without being choppy.Only OTA TV runs on KodiThe PVR needs to be another computer fast enough to keep up with the TV tuner. The TV tuner is connected to the antenna. I could get one end to work or the other, but I could never get 2 Raspberry Pis to capture AND play OTA TV. IMO, either the PVR or the Kodi machine has to be a PC class processor. Also, the PVR needs to have a large disk drive. You can use a USB drive on an RPi, but there is a limit of 400Mbps on the RPi bus (which includes ethernet, microsd card, USB, ...).The RPi plugs into one TV…

1. In my setup, each TV has a raspberry pi running kodi on osmcI have a pc running tvheadend on Ubuntu with four USB TV tuners. So, at most four TVs can be tuned to four separate TV channels. Start with one and add more as required2. The raspberry pi via kodi connects to a tuner and tells it the channel to use. If another TV tries to connect and no tuner is available, then it will show an error message like tuner not available.3. Kodi is the smart portion. It shows video on TV through HDMI cable. But sod my TVs are smart and they connect either wirelessly or via Ethernet to my LAN. I don't use smart TV features often.4. Tvheadend is the dvr. You can set and play recordings through any kodi device.5. My tvheadend pc was a gaming machine that I bought for my son. It came with a terabyte dri…

I am interpreting your question as two questions. #1 Can I control the system remotely? Yes, but I didn't implement a lot of controls. For example, I didn't see the need to change the zones remotely. From my cell phone, I can turn the alarm on and off. And I can trigger the alarm remotely, if some other device in my home automation system is reporting something wrong (or if I just want to annoy my wife).#2 Can the system send notifications when something is wrong?Yes, the system sends a text alert when it detects an issue. The python scripts contain the code. Basically, it sends a text alert through my gmail account to my phone.

Sorry, it looks like a typo. It should be: 239.255.0.1:1234, which should be channel 1. It should come from what you added when the command was run $ sudo nano klru.cfgand add # unique-multicast-ip:port always-on pid 239.255.0.1:1234 1 3 239.255.0.2:1234 1 6If 239 works, let me know and I will fix the typo.

Thank you.A1. I don't think the button has a built in resistor, but the GPIO pin does. I could have used the GPIO pin resistor. A2. My understanding is for the reset to work on the Raspberry Pi is for the circuit to be normally open. My guess for an on-off button, would be pressing opens the circuit (i.e., makes it off). So, you would want to use this in a situation where the circuit is normally complete and opening it would do something.

- jeff.cartwright.562 commented on jeff.cartwright.562's instructable Control a Cooling Fan on a Raspberry Pi 3View Instructable »
Can you check if you have the latest version of code from github? From your explanation, it seems there is a bug in the code.My design or explanation may not be the best. Basically, turning the fan on is dependent on the temperature, and turning it off is dependent on meeting a threshold temperature. However, the measurement of the temperature is not simultaneous with turning the fan on or off. There is a time delay, which allows the temperature to increase/decrease before it is reported. Depending on the application being run, the CPU can increase 20 degrees C in a few seconds. Increasing the delay may increase the size of this fluctuation.The above is why even though the fan starts at 50 it doesn't report the temperature until it is 52.6, and while it shuts off at 45 it doesn't report t…

Thanks! My old MacBook seems like a new computer. Instead of external USB enclosure, I used a USB 2.0 to SATA Converter/Adapter, ~$15. Before installing the SSD, I rebooted by pressing power key and holding down option key until I saw the boot drives. I selected SSD drive and booted from there. The SSD is very slow through the USB so this takes a while. When I was sure it worked, I installed the SSD. While I had the MacBook open, I vacuumed out all the dust from the fan.

1. HostnameWhen you set up the raspberry pi, you should have set the hostname.

Disconnect all pins. Put battey in geiger counter. Does geiger counter work? Geiger counter battery must be removed before connecting to raspberry pi. If geiger counter doesn't work, then you likely have a short. If geiger counter works, then ONLY connect ground and 3.3v, don't connect data pins. Measure voltage on geiger counnter between 3.3v pin and ground. What do you measure? On raspberry pi, measure voltage between ground and 5v pin. Please report what you measure.

I am a bit insane. Before I start on an instructable, I make a list of my requirements and then do a search for all possible solutions. Some solutions I throw out before I get too deep because they don't meet my requirements. Of those solutions remaining, I try to implement each one to some level. I'll start a draft instructable for each solution, and then at some point give up on it because it is more problematic than helpful. I then move on to the next one. I am sorry that OpenHab is not working for you.I found that OpenHab was confusing to install and get running, which is why I wrote the instructable.

A couple more guesses: * If all of the addons are installed, then it takes 5+ minutes for openhab to get to a stable state. Are you waiting long enough?* If the raspberry pi is operating correctly, then it should work the same way on every boot. Can you measure voltage on the raspberry pi 5v and ground pins? If voltage fluctuates and drops below 4.9v, then the power supply is at issue.

I am not sure I understand the issue. Is the Raspberry Pi hanging, or is your laptop unable to connect using a browser to OpenHab on the RPI? Please provide additional details.This seems to be an incomplete statement: "Boot message it is hanging on is:" What is the message it is hanging on? A boot message seems like the raspberry pi is hanging.Also, this doesn't look correct: "LSB: Rais network interfaces"Are you using Wi-Fi or wired connection? If Wi-Fi on Pi3, how is it configured?Are you using DietPi or Raspbian?Did you try running the unattended install, it should fix whatever is wrong?My wild guess is the openhab directory does not have the correct permissions. Some file in one of the sub-directories contains a file that cannot be read or written.

TO: jimmie.c.boswell, M2aestro and Gursimran Singh 425I read through the instructable and was interested by the comments and Singh's other projects. The combination of Singh's CFL-based light with wireless electricity is very cool. An LED-based lamp using only wireless electricity would be <fill in the blank> (more effective, higher lumens, more reliable, ... a bad idea, ???). And I am very tempted to pursue. However, this is way beyond my abilities/knowledge. Any chance one of you could make an instructable for this? Having reliable lamps that work at night and do not use electricity from the grid would be transformative.
