Hello! I'm sorry if this is not in the right topic. Okay, so recently I have been ordering parts to build a small handheld console using RetroPie and the Raspberry Pi Zero, now I just ordered a display, but the problem is that I am a beginner when it comes to SPI display connectors, so I would real...

You may be better creating a systemd service per thing you want to start up Yeah, sounds great, but using services, how can I know openvpn is connected, and then run another script ? Since the service is idle, is there any way to get a return value or something like that ? If the systemd service is...

In general for your .cpp and .hpp files (or whichever variant you use for C/C++). #include <stdio.h> #include <cstdio> is used for system (i.e. stuff that's been installed) libraries. The header files will be within the include path. In the example above those are both the same set of definitions th...

Reading through the various posts, this seems very conspiracy theory related. I hope you've all donned your tin foil hats :roll: IMHO I suspect the only people that might care about being able to track someone at that level are the various 3 or 4 letter secretive organisations, and then probably onl...

It appears that many of these solutions require the image to be downloaded at boot. In a larger wireless environment, we may be limited on the bandwidth for the downloading. Are there any solutions to manage the distros loaded on the local device? Things like puppet and chef are designed for managi...

If you're on a network where DHCP is in use (which is most networks these days), it is very poor form to try to use an address that has not been assigned to you. And note that even on the same network you were on yesterday, there is no guarantee that you'll be assigned the same address (DHCP grants...

@mfa298 : My script only has one command for now, but I plan to add some more now that the basics are working. The log file on desktop was just designed to have some visual stuff at startup to check if the script was executed or not. Thanks all for your advice and clarifications ! You may be better...

I am thinking of coding a set top box/ tv tuner software in c#, which will either run on Windows IOT core, or Raspbian (using Mono). You could save yourself some work and install tvheadend on raspbian with a tv dongle (or several). With Kodi as well you could probably have a fully featured set top ...

The good thing about Linux and the Pi is that you have a huge choice of available languages. There is nothing stopping you from using any of them. Most "real" software is written in C or Python. You should probably at least add ruby and rust to that list as well, and if you want to include language...

Do you guys think this is OK ? If your script is only running a single command you could probably get rid of this entirely. There's a whole load of stuff in there that seems redundant This is totally untested, and I've not really used openvpn so could be all wrong, but hopefully gives some ideas. [...

I can work through the coding to enter values, but how to use those values to overwrite the dhcpcd.conf in a manual configuration. I'd be tempted to have a templated version of the dhcpcd.conf (and anything else you need to change) and then use that with a suitable search and replace type function ...

If I understood right, I should use a service rather than rc.local or init.d (which are not working anyway ...). ... The script runs fine when launched directly from the console, but nothing happens when I do : ... Am I missing something, is my service file correct ? It may help if you provided som...

So let me see if I understand. The Raspberry Pi has a webserver installed (something like Apache?). A webapp is then written using something like Django. Clients then can connect to the server (either by being on the local net or exposing the server to the internet) and then send commands and recei...

I want the raspberry pi to be accessible directly by a usb cable, or at least the Pi Zero. There is a way you can do this by hacking the kernel, and I have done it, but I want the next Pi to be even tastier by ADDING A USB TO SERIAL CHIP!!!!! You know the raspberry pi rival, CHIP, the 9 dollar comp...

Take a look at the many systems management tools that are out there for *nix type systems. The likes of Puppet/ Chef/ Salt/ Ansible may well suit your needs. With these you usually install an agent on the devices to be managed (the various pis) and write rules on a central system for creating users...

As part of the other half of my project I'd like to display and be able to change the IP address of the PI via the 16x2 display and a set of up/down/enter buttons. Is this even possible? You should be able to find LCD displays that can be connected to the Pi relatively easily. Connecting buttons is...

I am currently trying to test the communication between a transmitting and receiving radio on the ground that will have to send a command a very long distance up into the sky(around the distance of the ISS) to a particular satellite that will then carry through the function and then send back the d...

I'm using an official Stontronics power supply, output +5.1v. Are problems usually associated with third party supplies or are the Stontronic ones temperamental? I've not had issues with the Official Pi PSU, although you may have issues if you plug too much into the Pi that's also trying to draw to...

Hi All, I have build my gateway / router ISC DHCPd version 4.3.1, which works absolutely flawless. I have setup firewall rules etc, including failed2ban for intrusion detection. Now I try to use BIND9 as DNS server, but it is internal on the same pi. I can't seem to get it to work. When I SSH into ...

I just wanted to let anyone who commented about only the legal side of things know, I was already fully aware of all legalities in my area and have already factored them into the budget of this project. I probably should have stated that, but I assumed it was a given provided what type of informati...

There's no such thing as an non-regulated band. The 2.4 GHz band used by wifi is an ISM band in the same way as 434MHz and 868MHz and still has power and/or duty cycle limits. If you gave some details of what RF modules you're currently looking to use and what you're actually trying to achieve then...

What if I broadcasted on a non-regulated frequency such as 5.8 or 2.4ghz? I planned on modifying the circuit to add power to the signal. To my understanding, it just takes an input frequency and recreates it using the new power supplied to the circuit. So in theory, wouldn't supplying more power to...
