The PhotonHome is an open platform built upon the Particle cloud backend. Gone will be the days where hobbyists and their hardware/software projects are limited to controlling just sensors and low power devices.
By building a safe platform for people to control AC power, makers will be able to make real physical changes to their environment. Possible things to connect and control can be lights, refrigerators/freez

Why This Is Important:

What kinds of things do you make? Do you make things for entertainment? What if you could get paid for the things you make? The electronics that are all around us come in two types, the high-powered things like lights, and appliances. These appliances use a lot of energy, and do real work for us. The other type of electronics we have are the digital electronics, like phones, computers, and microcontrollers.

Microcontrollers can use less than 1 watt to do some really smart things.

Appliances use thousands of watts, to do some a really simple hard thing, like heat, cool, make wind, pump liquid, create humidity, or boil.

Do we want to all re-invest in smart appliances, when at this point there is no clear standard for IoT communication?

The PhotonHome takes that problem and goes to the root, which is A/C power. Linking together A/C devices at the outlet level allows everything to be on the same page, without having to reinvest in brand new IoT appliances.

The Photon is an up-and-coming microcontroller providing easy WiFi connectivity with a built in cloud backend. The key to PhotonHome is that it is the home base for a network of WiFi enabled sensors, and the somewhat dangerous part of interfacing to A/C devices is ready-to-go and safe.

PhotonHome is empowering makers to use their electricity in a way to create value. If we can figure out how to be even a bit more self-sufficient in our lives, then that is a good thing.

Features:

Control up to 4 A/C wall outlets.

Enclosure isolating the A/C voltage away from user.

Allows the Particle Photon environment to control A/C devices.

Example Projects:

  • Frost Ferment a Lager using a temperature sensor, and a minifridge.
  • Use a space heater and a temperature sensor to maintain a room temperature, rather than get too hot while you sleep!
  • Maintain a garden using a heating mat, humidifier, lights, and a fan.
  • Make a fractional still, using a k-type thermocouple, water pumps, and an electric range....
  • Boil liquids, potentially even with the science-y kind of stoves with the stir bar, for a certain time or temperature with a k-type thermocouple.
  • Grow bacteria/fungi in specific temperatures/humidities, for whatever reason of your choice?

We want you to go out there and make something of value with the PhotonHome.

    I have been working on this project for a couple years now, and I have finally made something that is fairly easy to make and useful for me, but I always wanted this to be useful to others. This project has 790 followers, but only 4 comments!! Who are you people out there who thinks this could be useful? Message me! I am thinking of doing a small (5-20) production run for friends and family, and wanted to put my value proposition out there:

    Who is interested in a 4 controllable AC outlets with AC current logging, powered by the Particle environment, and temperature/humidity/light intensity sensing for <$100? And it has a web and iOS app interface?

    I think this is could be the home "growers", brewers, makers, distillers new favorite toy.

    Please I need any feedback I can get, if anyone messages to express any sentiment to me about the project, I will post a public GitHub repo with PCB design files, Bill of Materials, Software, and Firmware. (its currently private for my ease of login and security, not for lack of transparency)

    Check out this demo application for the PhotonHome, growing hydroponic pumpkins. I first started a number of pumpkins in a coco coir and vermiculite mixture in a starting tray from a garden store, then I moved the two best growers into the clay balls "hydroton" in the planter. Right now I am planning on doing a 5 minute water every hour, but maybe 15 minutes every 3 hours might work better?

  • AC/DC Converter

    sako093801/23/2016 at 23:31 0 comments

    I found some nice AC/DC converters from Jameco Electronics, which are fairly high current switching ones. I got a 5V@3A one for $10. This allows me to put this in the case, and have the entire system be powered from the AC power input. No more external wall-wart!

    Also, my Photon sense PCB is at the fab. That will have 2 NeoPixel outputs, 1 thermocouple, 1 controllable USB, and 1 DHT22 Temperature and Humidity sensors. I have gotten the parts already in the mail. I'm glad the AC/DC converter worked well, because for the NeoPixels, I'll need a lot of 5V current.

  • Sense Board Complete!

    sako093801/16/2016 at 23:04 0 comments

    This is a bit of a side project, but I need more Photon sensors to control the electrical outlet controller. I am creating a PCB with:

    2 - NeoPixel WS2812B outputs.

    1 - USB port with power switching

    (This is to test the switching high-side switch, which will be featured on the next PhotonHome revision)

    1 - DHT22 Temperature and Humidity Sensor Input

    (I can't keep putting the whole sensor PCB in the freezer, its going to short someday)

    1 - Thermocouple input header

    (This requires the SparkFun Thermocouple Breakout - MAX31855K)

    Here is the schematic:

    Here is my first pass of PCB routing:

    Once I get paid for another electronics job, I am going to order this board and the materials for the next iteration of the PhotonHome. This board will give me the sensor functions that I need, and test out a few circuits which will appear in the next PhotonHome revision.

    Here is the video: I used the device in order to control a space heater. I used the space heater and the SparkFun Weather Shield in order to defrost my refrigerator, but with a control system so it doesn't get too hot and potentially melt plastic. Check out the video, you'll be able to see the new case and a full working demo!

    Hello everyone! I am super excited to say that today my project reached 100 followers, (I'm at 102 now). I am super grateful for the support. I am also super excited to project is finally in working order.

    Now to the tech: Over this next week I plan on devising some software to put on the controller that will let me do a variety of outlet controlling functions, and do it in a consistent way so I don't have to open up the box in order to reprogram the Photon continually.

    Lastly I just wanted to say keep following the project (and share!), and expect some big developments over the next couple months. I am currently building a Photon powered PCB reflow oven(its like 70% done), and with that reflow oven I will be redesigning the board to include a Particle P1 module, and a small AC/DC converter that will allow the P1 to be powered by the AC wall input that is already required.

    I believe I have all the skills necessary to get this done, and I hope 2016 to be my breakout year!

    PS I'd love a comment. It shows people are listening. I'm thinking of migrating over to a solid state relay, and hopefully a powerful one at that. I'm playing around with SparkFun's 40A one, but if anyone knows of any high powered, but fairly cheap one, I am all ears. DigiKey averages like $20+ each for the power I am looking for, while SparkFun's is only $10.

  • Breakthrough Day! It works!

    sako093812/30/2015 at 06:15 0 comments

    After finally obtaining the last component of the project, (the 5x20mm 8AMP minifuse!!) the project has finally come to fruition! Luckily I was home for the holidays and I got to show my parents where their venture capital went to. My dad helped film this video and helped me get through the message of the PhotonHome:

    The two boards featured in the video is the Particle Relay Shield, and the SparkFun Weather Shield. Upon finally getting everything wired up and complete, without any software at all, using the Default "Tinker" Photon application which allows toggling IO pins using a smartphone, this in turn toggles the relay which switches mains power to the outlet.

    That was an exciting first step! But what is even more useful is using sensors to toggle the outlets. I already had a simple app for recording the temperature and humidity using the Weather Shield, and within two minutes I had the Weather Shield sending humidity threshold events, which can be received by the outlet controller in order to toggle the outlet.

    Finally, today I made the DHT22 interface board, which will allow me to use my 3D printed DHT22 holder shown in the last project log. Also, another Photon board was built which has DHT22 input, and NeoPixel output.

    For the final project demonstration, which will be happening soon I will have high voltage wires in the case, and interfacing with the DHT22, the NeoPixels. These systems will work together in order to take upmost control of your home, and your projects.

  • Progress Hasn't Stopped!

    sako093812/21/2015 at 00:04 0 comments

    Just wanted to let everyone know that progress has not necessarily halted, though I lost a lot of motivation to post when I didn't advanced in the Hack-A-Day prize.

    New Developments: I have spent so much time creating PCBs for this project, when I have mostly looked over pre-built solutions and using that in the project. I have finally caved... And I think it was a good learning experience to try going the hard way though. I've decided to use the Particle Photon Relay Shield instead of making my own relay PCB. The annoying part about their board is the connector they use only allows using smaller gauge wire, and the connector doesn't have common entry point, which would make sense, seeing as they are advertising as good to use for AC. But check out the new entry to the family!

    The board on the right is the Photon Relay Shield.

    Also, while the SparkFun Photon Weather Station was pretty cool, what I really need is only NeoPixel LED output, and a temperature and humidity sensor. The DHT22 is cheap and easy, so I made a 3D printed body for it, and plan on putting a tiny circuit board inside, which will provide the 10K pullup for the data line and then just a 3-wire JST output.

    Finally! Woo, that was a lot of pictures... I had a class this semester at CU Boulder called Democracy in the Digital Era, and we made the "Voting Booth of the Future", look up CU Boulder ATLAS Expo! But I made a dual NeoPixel strip, and single button input PCB, for the Photon. I plan on modifying this PCB and getting it professionally printed, but also add an input for the 3-wire DHT22 sensor. I have 2 more level-shifter outputs remaining, should I add more NeoPixel outputs?

    The board on the right is what I made for that class, and plan on modifying super easily. As for the the gray 4-gang case, I drilled a hole for my AC power input, and that fits nicely. All the wires inside are connected using nice quick-connect or ring-terminals, which is why I'd love a better connector on the Relay Shield!!!

    Let me know what you think of the progress! The end goal of this project has changed just slightly, its Winter Break so maybe I'll get around to updating all of that.

    :)

Cool project, is this open source? I'd like to build this myself. I didn't see a link to any of the design files or code.

sako0938 wrote 01/23/2016 at 18:53 point

It is actually running with a stock Particle relay shield, a photon, a power input connector, and ... I'll get an updated parts list with the specifics on it. Things moving too fast to keep it updated. Just got an AC/DC converter in the mail, though it should be the finishing touch.

sako0938 wrote 06/11/2015 at 19:56 point

The posted PCB is a little iffy. What is currently under development uses an isolated switching regulator, and optoisolators to protect the user side from the AC side. I guess I will do UL if it seems people may really want this.

zakqwy wrote 06/11/2015 at 19:51 point

Are you planning on going after agency certification (UL, etc)? I don't know much about things like clearance and creepage other than that they exist--I'm assuming you've followed generally accepted rules for this stuff?
