  1. Never gave it a try, but apparently some people had good experience using Tile Bluetooth tracker (or other variations) for tracking stuff... maybe give it a shot?
  2. This is a extremely simple project, but, it saves me so much time. One of the things that started happening way to often is, I'm not the one who is misplacing the TV remote but I'm always the one recruited to find it... which is not fun. So I built my own WiFi remote, it sits on a shelf and I interact with it with my phone and PC. Honestly, I wish my smart TV has this feature since now I don't even need the remote that came with the TV. Hopefully someone else finds this useful too.
  3. I've ordered some components from DigiKey. Unfortunately there is no eval board available for the ICs I want to try, so I'll have to build my own, which will take some time (release design, wait for PCBs to come back...) but at least we are moving! @startrek03 I was thinking of maybe using Python and Qt, but if majority of people use Windows, it might be easier to use C# or VB.Net to make something. I will create an API document to show how you can communicate with the hardware, then there will be one or two apps (Python and .Net app that I/we create) and then anyone in the co
  4. @Som3a that's a very good point. I'm thinking of having something like: simple and advanced display. Ie if you just want to set the fans to certain speed or configure them when to turn on/off, it's two clicks. But there should be an advanced view that you can choose to turn on, and it should give you ability to tune and change every feature/option. Also, I'm hoping that since this is going to be open-source open/hardware project, people can contribute by writing their own guide, video or a tutorial how to do certain things. In my mind beauty of open-source and open-hardware is
  5. Awesome, thanks @startrek03! I like the mockup on the right with "split window" design. I believe something like that should be fairly easy to implement. I like the idea of having information grouped in their own tabs and then showing only relative information instead of spamming the entire screen with all the information and all the settings. I'm still long way from the SW component but I'll put this in my notes so I don't miss it later on. Currently I'm in the phase of selecting components for driving the FANs, making sure they are available, affordable and easy to us
  6. Great point! I'm not an expert when it comes to UI/UX but maybe someone would contribute with some mockups, ideas or constructive criticism once software part is up and running. Do you have an example of an app that has great UI that you like or think it would be suitable for this type of project?
  7. Thanks thrasher_565 for the feedback. There are plenty of solutions out there, but most of them are closed source and in some cases price tag makes it hard to justify buying something that just turns the fans on/off. With open-source, open-hardware solution, you would get something that you can build on your own, if you want and also customize any way you want. I don't expect everyone to do this, but it's enough that couple of people take the advantage of open project and modify it to fit their need and then share back to the community. My impression is that a lot
  8. Thank you for your feedback, I'll make sure to include progress pictures and updates. And just to make sure we are all on the same page, when I say support, I don't mean / expect any money or any other compensation. I'm doing this because I'm and enthusiast and I love doing these projects and would do them anyway. By support I mean suggestions, feedback, ideas or doing something for the project.

  10. For a very long time I was planning on designing my own fan controller, and I'm finally doing it. I want to release the design as open-source/open-hardware so anyone could use it and benefit from it. Now with that said, I want this project to be driven by the community. This means that my goal for this project is to design something will be: Helpful / Useful - you can use it to solve a problem, or improve the quality / reliability Open - Design must be fully transparent and well documented. This way new features and integrations can be easily implemented. Acc
  11. Thanks! Mainly because it's much easier to make any changes (i.e. add content, fix typos and etc) in one place vs many. For that same reason I use git to provide all the resources and just post a link to the github repository on my website. :)
  12. Hey folks, I'm not sure if this project of mine passes the criteria for a mod but I like to think it does and I've shared instructions and source files on how to build your own. Here is the link to the post. I've been playing around with this idea of showing usage metrics but in a more analog and "cool" way, so my solution for now is having a "dashboard" of sorts, with analog gauges that show CPU, memory, network and GPU utilization. To be honest, it doesn't do much, but I think it looks super cool and I hope it helps someone build it into their ne
  13. How many cards? Do you need to differentiate them or just detect when card is present/absent? If you need to differentiate them, then NFC tag and NFC reader would be a start. If you don't care about which card is placed, just is it placed or not, then for detection you can use magnets and reed switches, light dependent resistor, proximity detector or a simple emitter and receiver LED. Try explaining your project a bit more and you will probably get more details, maybe even links to similar existing projects.
  14. I agree, Nixie tubes have a certain vibe that hey bring to every room. I'm definitely going to build one of my own when I get a chance. Only downside is that Nixie tubes are so darn expensive since they are considered "luxury" item nowadays, which is understandable considering their use-cases. I like that whoever looked at my clock, at a first glance they thought it's some kind of artistic installation or cool animation made with LEDs and then when they find out it's a clock, they are even more impressed.
