Yeah, it is written funny. But what it means is that the Linux kernel already comes pre-packaged with the drivers necessary to communicate using the protocol used by this device (UART or USB). These Linux drivers (and by extension Raspbian) are natively capable of interfacing via the GPIO pins or via the USB connectors. It is not true that the device is “driver free” as you always need a driver for this, what they meant is that it is not necessary to install any additional drivers for Linux. So “free from installation” I suppose.

Windows does not come pre-packaged with these drivers, so you need to install them if you want to interface with the device via USB. The chip that the board uses for the UART -> USB conversion is the CP2102. This chip is a common chip used in some ESP32 boards, and I think it would work fine with the standard CP210x driver. But on their site they do provide a specific driver for free (SIMCOM_Windows_USB_Drivers_V1.0.2.exe)

The board finally arrived and it is indeed the SIM7600G-H, which is the global version.

I tried it on my raspberry pi 5 and struggled a bit because there was a change to the UART interface between the PI 4 and PI 5 and the documentation on this board describes the PI 4. But, after some fiddling around I figured out the correct setting and got it to work. The main difference is that the “UART0” needs to be explicitly turned on because the default debugging UART now uses the UART10 interface that is somewhere else on the board.

Thanks for checking!

SMS for 2fa is deprecated here because of insecurity and TOTP is generally preferable. Can you use that instead?

My first choice is a YubiKey, second choice is the Aegis Authenticator app, and the phone I only use for services that force me to. A few still do, unfortunately!

I understand about DIY and am interested to hear how this goes for you. I might like to try it myself.

If I manage to set up something that I think is interesting and functional enough, I will post about it 😄

If you can use those sims in mobile phones then I’d call them mobile plans. Can I ask what country you are in? Here in the US, mobile service costs a lot more. I have been getting SIP service from vitelity.net but twilio.com and voip.ms are better known here. I don’t know about jmp.chat.

The Netherlands. I just checked and it is €10 for 5GB/month or €8 for 5GB month if one pays for a year: https://www.lycamobile.nl/en/bundle/monthly-plan-xs/?m=12

But in the shops they have signs with deals and you can get often get codes for cheaper. They print out the codes for you and you can top-up by issuing a USSD code when needed. I buy a stack of codes, type them into my notes app, and use them when I need them. Since I commonly have WiFi available I sometimes go months without activating them.

In the home base I wouldn’t need data, as it is interfacing through the raspberry pi. Most of my phone activity is getting codes for 2FA for some important services that force me to. Since I rarely make calls, I can top up €5 of credit when needed. I need to make sure to top up every 6 months so that the SIM does not get deactivated. That’s why estimate ~€10 for every 6 months.

This works for me because I do not use the standard phone features (SMS and calling) often. If it were up to me, I would not have the phone functionality at all and simply keep the data. But sometimes I need a phone number. The purpose of this project is to keep the convenience of having a phone in the rare cases I need it without constantly having on me a device broadcasting unique identifiers. As for why go self-host route… I think the same can be said for many other self-hosting projects, it is nice to have more control. It is not really about the money. Saving money is part of the fun, and that is an easy way to “justify” what I’m doing… but the reality is that any savings argument probably gets thrown into the BS pile when we account for the time invested, failed attempts, and the extra stuff I buy for trial and error. Ultimately for me it’s really not about money, it’s about being mindful, learning, and having fun.

I haven’t had trouble using a hosted number for banking and it feels better to me than using a mobile number. The cheap mobile providers (MVNO’s) I use here are sketchy, mobile numbers change all the time, etc. I use a VoIP number as my permanent stable number and forward it to my mobile. So if I switch mobiles, I just change the forwarding. In theory you can port phone numbers between carriers but I’ve had significant hassle doing that. That’s just here though. It may be different where you are.

I have found VoIP numbers from Canada and the US, I am not sure if it is easy to get one from the Netherlands. I have experience being banned from sites immediately after registering with the VoIP number because of “suspicious activity”.

Thanks, I will look into those.

Is there a reason you don’t want to just use a SIP service by the way? It would certainly be cheaper than that board plus a mobile plan.

At the moment I am using a SIP service - at least I think I am. Is JMP.chat a SIP service? It works to a degree for me but there are many drawbacks. I can’t get a number from my country, many services recognize and block the phone number as a VoIP phone (for example, telegram), and I have to trust an additional intermediary to get my unencrypted SMS and 2FA codes. I do trust the service providers to a reasonably high degree, but I don’t think it is wise to associate their numbers with sensitive accounts such as my bank account.

The VoIP idea is not the reason why I began playing with these boards in the first place, though. It is an idea that I thought of while playing with these modules. And I don’t use mobile plans. I use sim cards that I can top up when needed, so the cost is about $5 every 6 months or so for the home base, and about ~$5 a month for the data I use for my mobile router. The reason why I want to control the device through the raspberry pi is that then I also have more fine-grained control over the top-up process and I “own” my phone number without an additional intermediary.

I agree, it looks like a nice board!

But… after ordering it I noticed that while the pictures in the website show the “SIM7600G-H” chip - which supports global GSM and LTE bands - the text description specifies that the chip included in the kit is the “SIM7600CE-T”, which supports the Chinese bands. I am not sure I will get the correct version now 😅 But there are other “SIM7600G-H” modules and USB dongles available out there, and from what I have found this chip is a nice option for GSM/LTE projects.

Thanks a lot for digging! This is a very useful

Ooh, thank you! This looks exactly what I am looking for.

If only I could get my contacts to join me… I have two (real-life) friends in XMPP and none in Matrix 😅 I count my blessings and am thankful to have a few contacts that use Signal. I make sure to compensate them for their service with memes borrowed from Lemmy.

My Reddit meme experience:

1. It rings a bell but I am not familiar with the details, I will look into it but I can’t address it right away. I am well aware that the US is an imperialist nation that has committed and continues to commit horrible acts all over the world. But the point is that this is not the official narrative of the US government. They may give some concessions about what occurred in the past, but the official narrative about what is happening now is always that they and their friends are the good guys.

2. I am not from the US and the question is about conspiracy theories in other countries. If the question means whether Americans are more prone to believe US-conspiracy theories, then yes, simply because they are much more likely to be aware of them. Many people in other countries don’t consume as much media in English and might have no idea who Jeffrey Epstein was. So they probably have no opinion on whether there was foul play on his dead. But I think that if you talk to someone in Mexico and tell them the story of Epstein, most will agree that there was foul play involved. I am telling you this from my personal experience, at least within my circle but I think it expands more generally. We have a general distrust of the government and law enforcement, and so a story in which foul play is involved to silence someone else resonates. It happens all the time! Journalists are being killed all the time around here to silence them, and very often they are being critical of people in power… Is it really that unwarranted to be suspicious?

Fascist as in the US actively supporting and financing terrorism in countries it wants control over, historically.

Isn’t this a conspiracy theory? I think that the official position of the US is that they are not financing terrorists, and many of their military actions have been performed to defend citizens from their ruler’s human rights violations. Isn’t the Cuban embargo officially there to protect the Cubans against human rights violations? I think that arguing otherwise makes one a conspiracy theorist.

I am not saying this to argue, I am trying to explain what I understand with conspiracy theory - someone who is skeptical about the official narrative, and believes that those in power will not always be transparent and honest to the public.

And I think that being suspicious has been co-opted by the right wing, yes.

I am aware of the “drain the swamp” rhetoric, that there was a QAnon, anti-vax, and other more fringe theories. But I think that this is a sub-set of conspiracy theorizing that is amplified by the media. Many conspiracy theorists are investigative journalists and critics of governments. And many conspiracy theories have ended up being true. I don’t think that critical thought and skepticism is an exercise that only right-wingers should participate in.

What do you mean? Can you describe what you mean with ‘fascist rulership’? Then maybe I can try.

For example… people in Mexico many people suspect that politicians have associations with drug dealers, and many believe believe that particular bureaucratic systems (such as handing out public infrastructure projects) are exploited to distribute funds in ways that benefit those in power and their friends, these people I would classify as “conspiracy theorists”, and in many cases they have been correct. You think that these people will always side with fascist rulership?

I think that the distrust of governments and generally those in power is a world-wide phenomenon. But I personally don’t think that it is unwarranted. Corruption, abuses of power, and conspiracies are widespread.

“In November I had received two letters from Teachers’ Pensions asking me euphemistically if I was dead,”

I am curious about how one euphemistically asks someone if they are dead. Any guess?

EDIT: Ah! After sending this answer I saw jorge’s answer!! So this answer is redundant, but at least you can see that two people arrived at virtually the same conclusion 😀

We need to define a threshold of energy that we consider “ionizing radiation”, and we also need to a more precise definition of “starlight”.

I will arbitrarily select the ionizing radiation threshold to be at 10 eV (124 nm). As for “starlight”, let’s just say that we want to push the 750 nm red light all the way until the point where it becomes ionizing. One thing to consider is that in this situation you will also push infra-red light from the stars towards the visible, so if a star emits a lot infrared this IR light will become “starlight”. So the answer can be muddled up by all of these definitions as well as the emission properties of the star.

To keep it simple… Let’s shift 750 nm red light to 124 nm ionizing radiation. You can rearrange the Doppler expression from this website to solve for the “v” to get the velocity needed to transform 750 nm to 124 nm. The solution I get is -284,035,329 m/s, with the “-” sign indicating movement of the receiver towards the source.

You can double-check by inputting 750 nm as the wavelength from the light emitted by the source, -284,035,329 m/s as the velocity, and the speed of light as “c”:

Then, if you agree with the assumptions, definitions, and the analysis, the receiver needs to move at about 94.68% the speed of light to shift the redder starlight into the ionizing radiation range.
