Idea Dump

  • By the way, I am discarding this idea...
    It was to provide a cheap yet reliable way of zoning HVAC to specific rooms using not vent covers, but shunts built into the ducts.

    Zoning HVAC is a very bad idea unless your HVAC itself is designed for zones. You end up either icing the condenser or overheating the blower. So while I like the ideas of pairing Onions to have each do separate tasks but work in concert, and the idea of snapping an Onion into a 120v mains instead of consuming an outlet for a transformer wall wart, these two ideas would not make for a good HVAC solution in the common household.

    Okay, I see this for Android but not for Linux. I'm sure I'll find something. I was just wondering if there was anything baked into Omegas.

    @TheMonkey-King said in Idea Dump:

    I need to read the APK guide, I suppose....

    But I wonder how hard it is pair (bluetooth) two Omegas (or Omega2s) together?

    Basically with the pair, you have one doing the monitoring and the second performing tasks. The reason for pairing is that the system is not completely shut down by one of them going out. True, the one performing actions could still be performing incorrect actions if it is the problem module, but there is an idea I could program a baseline action that performs no actions as the default.

    IF [one] perceives <threshold_event_z>, then
    [two] performs <action_z>
    IF [one] perceives <threshold_event_y>, then
    [two] performs <action_y>

    Would love if you could create offline / paper-wallets for bitcoin on the device, all automated and all that.

    this is a nice idea. It is something that i am looking into. I actually had the notion of creating a node on the Omega - but i am not sure that it will be possible. Will be looking into this further during the month - i only received my Omega2+ last week :) - and i will keep you posted.

  • I found a project idea on that I'd like to try with Omega2. Basically, putting up lights on the underside of the kitchen cabinets, with a motion sensor and an ambient light sensor to control when the lights turn on and how bright they are. Not really sure what I'd need yet, I have the Omega2+ with the expansion dock.

  • @francis-chung i would like to build a app to be able to code on the go. when ever you have an idea you just take your phone and code. i have the base visual of it but i need help to implement languages and have maybe a Github API to push projects.algologic_menu algologic_input

  • @Guillaume-Langelier this sounds interesting. Can you give use case example at how you expect it to work or how the user will use it ?

  • "The" panic button .

    Once you press it start a series of task like sending a message (email, SMS even WhatsApp and Telegram). It could also know your location with the GPS module.

  • Hi guys, I'm trying to set up an array of addressable RGB LEDs to create a large 8 bit style display. Maybe I'm just not looking in the right places but I can't seem to figure out how to go about setting this up... thoughts? Also I'm working with an omega2 and an omega2+

  • An automatic router rebooter, but one that would use the relay expansion, not the big, fat relays also available.

    Oh, and make it a full monitor, display average speed, data transferred, and last 5 pings on the OLED display. Sometimes routers fail by giving enormous ping, but don't disconnect.

  • Is it possible at all to stack several Omegas on Expansion docks to then create a tinie tiny web server? There's some obvious concerns: Powering all of the devices, configuring them to properly communicate with one another, and if it actually will work at all.

    PHP, Python, Ruby, and Java all have micro-frameworks that would/could work for a project like this; so programming it wouldn't be a huge issue.

    Use a stack of ethernet expansions. Then, use a switch and load balancer system for all the omegas.
    If you want to stack them with direct GPIO, I see too much trouble to make it work fine.

    It could look like this:

  • 16x 32 display board controlled via phone or pc
    I would like to make a 16x32 or larger led display board to put in a shop window and have it say open or closed and perhaps show store hours that I could control with my pc or phone and add timers to it. I'm wondering if anyone can or has designed it with the omega or omega 2 ?
    I would use something like this;searl|1071565168
    but I need to know what else I would need besides the power supply can anyone offer advice ?

    That seems potentially similar to a product Adafruit used to sell and posts some resources for at

    Going by what is there, it may be easiest to interface by using an auxiliary microcontroller to drive the display, and then set the message over a serial or USB interface from the Omega. For example, Onion->Arduino->Display.

    That's not to say that a direct connection is necessarily impossible, but unless you are designing a product, the effort in finding suitably precise control over enough I/Os and servicing them regularly is probably not worth the trouble compared to the cost of adding a helper micro, and even in a product, that helper micro could cost less than a dollar, while giving flexibility to replace the Omega with a different wifi solution in the future.

    For that matter you could possibly build the whole thing around an ESP8266 instead, though you'd likely need a board that exposes almost all of the pins and not just the few of some boards.

  • @José-Luis-Cánovas now that you mention it, directly connecting them via GPIO seems a little convoluted when you could just do what you suggested. I could make a server rack, getting ethernet cables isn't an issue, getting a switch and a load balancer system isn't an isse, it's now just a matter of saving up and getting 3-5 more omega 2's, AND ethernet expansions. It sounds like a super awesome project to do though.

  • I would like to build a functioning robot made with the Omega 2 plus. Are there coding languages that need to be downloaded?

  • I would like to build a digital photo frame with Instagram or Google photos feeding the photos.
    Has somebody already done this?

  • I would love to build a simple setup where the onion2 can run on a battery and be placed in a park or similar. here it should log all "devices" that it sees when scanning for wifi/bt devices in the surrounding. I would like to have a bunch of these setups in the same park/plaza and use the logged data from all of them combined to do a sort of movement pattern analysis for the guests.

  • I am trying to make a flexible digital led display, and I found one NEW LED "APA107 LED", so how can i make the display? and what kinds of controller/decoder i need?

  • 1- I'd like to build a simple alarm clock using Omega2+.
    It would display the current time in a 16x02 common "arduino display" (using Expansion board's GPIO), a common buzzer and blinking the Expansion board's built-in RGB LED.

    2- Build a level gauge for a tank.
    Where it can distinguish other and "heavier" liquids (in general, matte one) than upper water liquid (transparent one), measuring height of the "heavier" liquid without reporting the water height, just the other liquid.

  • So my "crazy idea of the week" is to build a module that will go in one of the GBIC slots on my Cisco 3524 switch to add wifi capability to it. I think that I could do this by marrying an existing 1000-base-T module for the switch and maybe (if the GBIC slot doesn't provide power/enough power) an external power source. Sadly, as much as I really want to do this and get rid of the consumer grade router that currently sticks around only to provide wifi I have neither the time nor a 1000-base-T module lying around.
