Re: Send SCPI command to a RP 3B+ using VISA thought Ethernet
Hi, I don't know if there is an implementation of a SCPI server running on Linux/ARM, but if I remember correctly, SCPI protocol is just plain ASCII commands. You could then "just" write a TCP server in your preferred language that parses the string comming from a TCP socket and responds a...

Re: Is MAGI mining profitable?
Pi3 gives me 11 khash/s don't have an energy meter attached to it so not 100% sure of it's usage. How do you achieve 11 Kash/s? I've just compiled it, and it runs @ 4.4Khash (4*1.1). Did you use special compile options? Overclocking? Thanks Nothing special other than using the 64bit OS https://gith...

Re: 24x7x365 Products using RPI2-How to get rid of Kernel Pa
USB Flash drives use the same memory technology than SDCard, and they have the same "weaknesses": they support a limited number of write/erase cycles on each memory cells. The error message you get could be caused by a filesystem corruption because of a faulty flash drive. I once tried to ...

Re: Elevator project
It still makes no sense. Getting stuck in a lift because the interface is busted is no fun. The same would be true for any other GUI application. Windows PC, Android phone, car entertainment system,... everything tends to crash one day or another, it does not make sense, but it happens... The mere ...

Re: Transmission drop connection
You mean that your internet router gets disconnected from the internet when you download a torrent from your RaspberryPi? Some router cannot handle a lot of connections at the same time, and torrents tends to connect to a lot of peers on the internet. The router from my ISP had this problem, it woul...

Re: Elevator project
Certainly not one for commercial use. It depends on what the RaspberryPi would be used for... If the rPi is used for driving actuator, reading sensor and garantee the safety of the elevator, you're right. But if it is used as an HMI (Human Machine Interface), GUI,... which communicates with another...

Re: USB 2.0
If you really need all the bandwidth available on USB3.0, you'll need a higher-end (and higher priced) device. High-end NAS cost more money than a RaspberryPi, there has to be a reason for that... Some device may be compatible with USB3.0, but may not provide the full speed of USB3.0. That beeing sa...

Re: Personal distributed "cloud" storage
Yeah, rsync is an easy solution, but it is not really "distributed". Rsync will synchronise data from one box to another... But if I have 3 or 4 boxes, synchronisation might become a nightmare... Here is an example of what I have in my mind : I build 4 identical boxes (rpi + hard-drive). I...

Hi, As many of you, I have a lot of data (music, files, work, pictures,...) spread across several devices and hard-drives. I would like to safely and easily backup all my data, and perhaps the ones from my family and friends. I could buy a NAS and a bunch of hard-drives, but it's quite expensive, an...

Re: Combining 2 tutorials
You can store the result of gettemp() in a variable in order to use it later:
Code: Select all
# As an integer
tempDS18B20 = gettemp(id)/float(1000)
# As a String
tempDS18B20 = '{:.3f}'.format(gettemp(id)/float(1000))

From what I can see, you have merged 2 python scripts into a single one. Now, you'll have to rearrange some things in order to make it work the way you want. First you can remove the line #!/usr/bin/python (on line 39), because it is already specified on line 1. Then, what happens when you execute y...

Re: Two web server on the same RasPi
You can start as much webservers as you want (as long as there are enough ressources to make them run), BUT, they cannot run on the same port. In your case, you can start the first one on the port 8080, and the second one on the port 8081, for example. I don't know any thing about the 2 applications...

I searched for "soffice.bin" in google and found a lot of entries about soffice.bin eating all the CPU and RAM.
Are you using OpenOffice on your pi?
