Raspberry π

I'm basically a silicon collector at this point

Any news on what their power performance is like? I'm still on the lookout for dev boards that have a sleep current lower than 20ua. I'm having a really hard time getting the Heltec boards to meet their advertised specs.

Lol. I may have impulse bought a Pico W and another regular Pico yesterday.

I've got a Pentium 133 in a box frame on the wall above the toilet cistern

Doesn't look like it yet, but I wouldn't expect it to be any better than the Pico (0.8mA in dormant mode).

Is the heltec board based on the ESP32?

Handy if you want to make it water-cooled

Is the heltec board based on the ESP32?

Some of them are but the ones with the excellent claimed deep sleep stats are based on ASR605x

Not that it matters if you can't get close to the specs in real life. To be fair, we're getting about 1 year of operation out of the Heltec boards with a 300ma battery with our current code (and attached sensor). It should be closer to 2 years though.

They claim 3.5uA as opposed to the 20uA I said earlier.

Which boards specifically?

Linked in above post. Its a module, not a dev board.

Ah yeah I just thought from your earlier post you had a dev board

I do actually have a couple of the boards somewhere. Free to a good home if you wanted to have a play.

I was just curious! Thanks

Most awesome ^

Having another go at setting up a P2P/newsgroup downloader thing, nearly there this time, much helped by dietpi.

Last step is to set up OpenVPN, which is installed. Do I just replace the .ovpn config file with one of the ones provided from my VPN provider?

^ how does the syringe make the submarine rise and fall?

It’s got a tube connected to the outside of the submarine—it pulls in water as ballast to descend.

Oh, I must have missed that bit :)

I tried to do the same thing, gave up in the end as the pi just wasn't stable enough and would often crash when extracting large files from newsgroups. This was a Pi4.

From what I remember I just replaced the relevant bits in the openvpn file with the config file from my VPN.

Oh wow ok, I've done it in my laptop before but didn't realise it would be very taxing on the system.

Did you try increasing the size of the swap file?

It wasn’t really explained, I was confused as well

It probably depends what you're doing with it. At times I was extracting 50GB files together with the overhead from the VPN.

I experimented with a few things, can't remember if the swap file was one. First issue was overheating so I had to remove it from the case. A fan would probably have helped.

I didn't bother trying different software (I was using sabnzbd) so don't know whether that would have helped.

Anyone have a raspberry pi 400 for sale that they're not using?
