Been using SETI on the Pi3 for many months all is well and no issues. Just got a Pi4 and setup a fresh SD card with new copy of Stretch, added the SETI program for the add and remove apps, bit it didn't seem to install. One of the problems I have been reading about with the PI4. Seti@Home classic workunits:20,676 CPU time:74,226 hours   A proud member of the OFA (Old Farts Association) |

I will be back, but am very busy right now, so maybe to next week......... Of course there are those certain problems with my RPi 3B+, BOINC and Raspbian Buster still on - not getting packets ready. But let them be for a while. Hello again, finally back after a month. Last night I re-installed the Pi 3B+ with latest Raspbian, after that the Boinc Manager and then joined my seti account. Got new packets right away. I started small, just with 50 % capacity, and here it was this morning: my first packet for so long time had been crunched and uploaded. A new one already counting with the other that started yesterday. So, looks like everything is fine now with the 3B+. I wonder if this was guilty for the trouble I had before (packets did not get ready ever, starting all over again after reaching some point near finished): I use the Vivaldi browser. In the Vivaldi's Raspberry tip page there is a mention, that one should increase the Raspbian's swap size to 2048 MB to get Vivaldi running smoothly. That's what I did for both the Pi4 and Pi3B+ (I did not see any effect in Vivaldi's behaviour, though - Pi4 has 4 GB of memory)... Really can't know if that was it, but I'm no going to try again. Now I'm going to try BOINC and seti with the Pi4 again, that's a fresh install also, compared to those problematic times. There has been discussion over the Pi4. I can only say, that this thingy works nicely as my main computer. It does not run too hot at all, when installed into a passive heat sink case - the cooling element covers the Pi from top to bottom and looks good too. Even when running seti at 100 % temperature keeps at bearable level. Only complaints I have are the USB ports, that are not giving enough power to all peripherals I would like to have. But that can be solved other ways. Also the software gets updated regularly. Boot from SSD is what I'm waiting too... -iikka |

Hello again, Maybe it is the 'Add and remove programs' thing that's faulty with BOINC. I really don't know (again), but that is also something I did before with my Pi4, when having alien 'never ending' problems (with both Pi4 & Pi3)... Well, as in my last post I intented to do, I now just installed BOINC (with GUI) to my Pi4 from terminal, and all went OK. Now Seti is calculating the first packet since those alien days - I should tonight see, if packets really get through... -iikka |

Is the GUI fetching from a different location than the command line? |

I'm a newbie in linux world, and most likely got my systems messed up when ticking different setup options in the Raspbian's 'Add/Remove programs'... Huh. I'm learning slowly, and the command line seems to be best option many times. Anyway, both Raspi's seem to work ok with BOINC now, which is great -iikka |

[...] There's also a good article now over on Tom's Hardware: Raspberry Pi: Projects, Models, Prices, How to Get Started With over 25 million units sold, the Raspberry Pi is not only one of the world’s most popular computers; it’s also one of the most important. Originally designed to help kids learn about technology, this inexpensive single-board system is the leading choice for makers, developers and hobbyists who want to do everything from building industrial robots to setting up retro arcade machines...

Are there any SBC systems that Setizen's are running that are even sorta competitive with entry level X86 cpus? Besides Keith's NVIDIA Tegra 1? Tom A proud member of the OFA (Old Farts Association). |

I did a quick search and found this that might be interesting. :) Have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

Thanks for the link. I just blew more than 1/2 of an Amazon gift card on a 2nd Raspberry Pi 4 with the "official" power supply, the ICE tower and a SenseHAT. Last night I finally got around to overclocking my RPi-4. I've got it up to 1900 MHz using 4 over voltage steps. It's been up for 17 hours. It's Geekbench score went from 4800 to 6050, just over a 25% improvement. I'm hoping the new RPi-4 will do better since I had trouble with the first one (read on...). Months ago I bought a CanaKit case & power supply with a new RPi-3. The power adapter partially blew out the RPi-3, it has no power light. The adapter died a couple of weeks later. I thought that was a fluke so I bought a RPi-4 CanaKit since they were the first RPi-4s on Amazon. It's power supply zapped a brand new SenseHAT the first time I powered it on. The RPi-4 works but I won't plug anything into it. Two CanaKit power supplies burning out two RPis. I'll never buy anything from CanaKit again. My three RPi-3s use Miuzei clear cases and power adapters, they've been working fine. |

Well the EC YT channel rated the top SBC's of 2019 and the Nano came out as #1. #2 was the Pi4. He had a Intel SBC at #3 but it costs $400. Why bother? . . . . just buy a laptop for that price.

Thanks for the link. I just blew more than 1/2 of an Amazon gift card on a 2nd Raspberry Pi 4 with the "official" power supply, the ICE tower and a SenseHAT. Hi Sam, When I started with the Raspberry Pis I bought 3 Pi-3 CanaKits. I have had no problem with any of them. The only real problem I had was I tried a SSD on my first Pi and after some time, the Pi would no longer boot so I went back to the Micro SD card. Been running fine since. One thing I didn't use from those kits were the cases. I went with open cases for better airflow and cooling. Did you RMA your Pis? Have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

Just got a Pi4 and setup a fresh SD card with new copy of Stretch, added the SETI program for the add and remove apps, bit it didn't seem to install. Hopefully you used Buster and not Stretch. You need Buster for a Pi4. You shouldn’t add the Seti program, the project supplies the app and work units. Just install boinc-client and if you have a screen, boinc-manager. After that attach to the Seti project and it will download the multi-beam app. There isn’t an astropulse app for the Pi at the moment. BOINC blog |

As far as I know the SenseHAT sits over the top and therefore you won’t be able to fit the cooler, or if you fit the cooler you won’t be able to connect the SenseHAT. BOINC blog |

There are extended headers available and also extender cables available for the header to let you mount the HATs with greater clearance or even elsewhere away from the main board.
