Hello everyone!

I have a few projects lined up that I want to do, but I dont know where to order my parts from.

Up to now I was using grobotronics.com seeing as they ship to Cyprus which is where I am currently, because I needed basic stuff, but their stock is limited in terms of variation.

The parts I need for my project are a BNO085, Arduino Micro, and for a separate project some kind of STM32 (not sure which yet).

Anyone know a relatively cheap online store that has a wide selection of more these more specialised type components, that ships to Europe?

Thanks in advance!

Hello guys. I have island installed and have my "work profile" installed, which contains among others my browser in the island tab. The situation is that I have several PWAs that I dont want to receive notifications for while I am at work as they are distracting and unnecessarily annoying, but I want to receive them normally while not at work.

I have been trying to figure out how to get it set up so that I can both trigger the actions at scheduled times, or manually through the quick tile I created from macrodroid (my work hours are not really stable/fixed).

However, when testing with a push notification testing site, regardless what I do I still get the notifications.

Here is my setup so far:

Macros:
Enable Work Profile
--------------------------
Triggers:
    Day/Time: 08:00 Mon, Fri
    Quick Tile On/Press

Actions:
    Action 1:
        Target: Broadcast
        Send Intent: island.intent.action.FREEZE_APP
        Extra 1: package_name = com.brave.browser
    Action 2:
        Display Notification (with a message saying work mode enabled)

Constraints: None

Disable Work Profile
--------------------------
Triggers:
    Quick Tile Off

Actions:
    Action 1:
        Target: Broadcast
        Send Intent: island.intent.action.UNFREEZE_APP
        Extra 1: package_name = com.brave.browser
    Action 2:
        Display Notification (with a message saying work mode disabled)

Constraints:
    Day of the Week: Mon
    Time of Day: 19:00 - 19:01
------------------- OR --------------------------
    Day of the Week: Fri
    Time of Day: 22:00 - 22:01

Some things to note:

I am using /e/os version 3.0.1-t-20250606498724-official-FP5 Android is version 13

What am I doing wrong here? Ideally I would like to have as few apps installed as possible to achieve a single task, but as I understand it macrodroid doesnt have the necessary permissions to affect other apps notifications (hence why island is necessary).

If there is another way which is easier to achieve what I am trying to do I'm all ears, however I do not want to use do not disturb for this purpose because obviously I need to be able to use my phone normally while at work except for those 2-3 apps I dont want to receive notifications for, but there are also situations where I want a full DND experience where I will get nothing coming through, not even alarms (e.g. meetings/classes, etc). Also for those unfamiliar with /e/os, it doesn't currently have the Focus Mode feature so that is also out of the picture.

Many thanks in advance!

Hello everyone! I just wrote an extremely simply single-page tool using just HTML and Flask to convert google maps links to Osmand.net links, and I would like to host it somewhere.

I don't need any fancy bells and whistles, as long as it supports Flask as a backend.

Im no web developer, so I haven't actually hosted my own page anywhere before. As such, simplicity of use and setup is quite important. For example if it allows me to also buy the domain in the same platform thats good.

While I use Flask, there is no data being stored. All the flask app does is take the link given by the user, convert it to the osmand.net format, and return it. Super simple!

I looked on buy-european.net and found Infomaniak Web Hosting. I quite like the fact that they use 100% renewable energy to power their servers according to the page above, but I'm not sure if it would be the best option given how inexperienced with all this I am.

Would love to hear your suggestions! Thanks

Edit: Ended up going with hetzner. Site is pretty much set up right now.

gmaps2osm.de

It has some screen-reader support (still need to get it tested by visually impaired people), and is also set up so that you can install it as a PWA on your mobile device (add to home screen).

Here is the github repo: https://github.com/promitheas17j/gmaps2osm

I would really appreciate any feedback from experienced and not so experienced web developers alike :D

[Solution at end]

Essentially what the title sais.

I want to give this genre a try, but I also want to use mods. Also, Im on Linux so if there are any extra steps I need to do if I install through lutris/steam (as non-steam game) then I would really appreciate your input. The only reason I am currently considering steam as a non-steam game for the install method is just so I dont fragment my games library too much across multiple platforms/apps. If there is any reason not to install it in steam please also let me know.

Much appreciated!!!

[SOLUTION]

Turns out the torrent I found was just a .rar file of the game with the crack file already there. All I had to do was unpack it, then add it through Lutris as a locally installed .exe. I did have to change the runner to proton-ge as the default wine would not start the game. I also had to go into the prefix it created and apply this fix (steamcommunity link) to get it to stop displaying an annoying pop-up message every 30 minutes or so (yet to test it out, but it should work. Will edit again if it doesnt remove the pop-up message).

Also, strangely enough at least for my experience with pirating games, the in-game mod "store" worked perfectly, and I didn't need to manually move files to a mods folder, though I'm sure that would also work just as well.

EDIT 2: The workaround to edit the playtime in the game files worked and I no longer get the pop-up message.

Hello once again everyone!

I've made considerable progress on my thesis thanks in part to you guys answering my previous post here. I'm already writing up the report, and have pretty much the entire system programmed through the Arduino.

However, I am still having difficulties figuring out how to initiate/force a disconnect of all BT devices connected to the HM-10 module (this is the one I got). You can refer to the post I made on the arduino forums (link in post) where I also searched for the solution but had no luck, but sadly its been almost 2 weeks and still no answer.

To cut a long story short, I have all the pins of the HM-10 wired except the BRK pin currently, even though I wired that up previously and tried sending LOW-HIGH-LOW and HIGH-LOW-HIGH pulses to try to disconnect. As far as I understand it, what I have is not exactly the HM-10 but an HM-10 mounted on a breakout board(?).

The data sheet on the website I got it from seems to be for the bare HM-10 so its a bit confusing for me. It talks about a specific pin (PIO0) which looks to be wired to a switch, but there is no switch or button on the actual module and that doesn't help me anyway as I want to initiate a disconnect from code.

So how can I make it disconnect from all devices when the user for example selects a certain option from the menu of my system?

As always, I will greatly appreciate any help, and of course if you need any more info let me know and I'll try to provide it.

Hello everyone! First off, I need to mention that my background is in Computer Science (this project is actually for my thesis) and not in Electrical or Computer Engineering. As such, everything I've learned has been largely on my own, within the past few months.

That being said, I would feel more confident if an experienced set of eyes could take a look at my schematic and let me know if anything pops out as wrong/bad practice. Furthermore, with regards to the decoupling capacitor on the DS3231M RTC module (C1 on the schematic) I have a question: Would there be any problem if I use an electrolytic capacitor instead of a ceramic one? I read some stuff about the topic and people recommend using ceramic capacitors most of the time (I think) but others say that there shouldn't be a problem to use an electrolytic capacitor. I'm asking because I've already placed an order for parts, and one of them is this assorted set of electrolytic capacitors.

Please if you notice any mistakes or things that are not done the best way let me know, and try to explain why as simply as you can. As I said, I don't have a background in EE, even though it highly interests me and I want to learn.

Here is the schematic:

Many thanks in advance!

inb4 why youtube link when piped exists I have been struggling to find a piped instance that works recently. The instances I've tried are either Bad Gateways, dont exist at all anymore, or their search box just doesnt work (I type something in and hit enter/click the search button and just nothing happens)

Should I just buy the cheapest PS3 Eye camera from ebay and see whether I get the flat lens or round lens, and proceed accordingly?

Its a real hassle to determine if its a flat or round lens from the photos people upload on ebay, as they're not very good quality.

Edit: I found a really cheap one on ebay which was at auction and got the highest bid (it was a little over 4 euro with another 4 shipping, so honestly not bad at all). When it arrives I'll try out the steps in the video and report back here I guess. Hopefully it can help people when buying these cameras to not struggle looking for the rounded lenses and worry that if they dont get that one they cant do their project.
