I have serious concern whether this cable are able to power-on Raspberry Pi (which could have up to 4 USB device) and an external drive.
Have you used the cable on Raspberry Pi and other USB device without problem (no blinking red LED on Raspberry Pi) ?

Yes, I have 3 of them in use now. I was going to build another one and was looking for the same cable.
The Pi in theory can only have 3 USB devices because it is taking up one. But, so long as you have enough amps coming out of the 5V wall adapter it works fine.

It's more to keep it neat.

I think the Pi can also be powered by connecting to the GPIO pins. I'm not sure if that's a good idea as you typically want to power the Pi "normally", and any power hungry devices should either have their own power, or just connect as few as you can directly to the Pi.

A powered hub makes sense if you're connecting several USB devices, like more than one hard drive or SSD.

The Pi is actually good to run a full node since power consumption 24/7/365 is going to be like less than $1 a month, depending on where you live. I've seen figures close to $5 to $10 per year.

Signature. You know what to do.

I moved Bitcoin core to another device at 64% and the HD is now reporting errors on two machines. Errors also on Bitcoin core asking to rebuild the database. I can still access my HD. Sigh... I guess that means either the data or HD or both are corrupt? Letting core repair just starts the sync again from the beginning.  Cry

Try reindexing the Blockchain most likely while attempting to copy there were a few block files stuck mid-download or mid-index and resulted in corruption, reindexing should help you with that. If possible, it's probably better if you just download/sync it on your computer (to make sure everything works) and then just move the files to the external SSD/HDD which you can then connect to RPI.

Hello everyone,

this is my new post on this forum and I didn't want to start a new topic. I am also looking to learn to run a Full Node and connect it to Coldcard + Wassabi (in the future) and all of this is new to me. I was researching a lot last couple of days but found the best information in this thread. So in short I just wanted to as you guys about opinion:

Since I'm new to RPi and to putting my hardware together as well as running Bitcoin Core and Linux in general (yes, I've been living under the rock..  Grin ) wouldn't it be easier for newbie like me to:

- Download Bitcoin Core to my spare laptop ( i5, 8Gb RAM, SSD drive) and set blockchain to sync on external SSD
- Learn Linux (i was planning to do a course on this anyway)
- Then wait for stable version of new RPi and buy components (I've already looked into that so I know what I need) and learn to set it up there (preferably running over TOR?)
- Set the blockchain directory on RPi to that external SSD I've downloaded it on my laptop
- Enjoy compact size Full Node running 24/7 and then learn to use command line / SSH to broadcast transactions from my ledger to a multisig guarded by Cold Card (prefferably going throu Wassabi first for annonimity)?

Interested in your opinions. If this is wrong place I'm sorry, I'll post it somewhere else.

Cheers!

(all of this is what I've learned on Twitter, I've been lurking in this space for a while but never on this forum. Forgive me if those questions are super dumb)

You are right on point. I would check the third one though. Raspberry Pi 4 was released just not too long ago. I doubt there will be a new Raspberry Pi releasing in the next few years unless there is a huge jump in ARM technology. No need to wait for a new one if you want to use your wallet.

Welcome! Indeed, this is a perfect place to start. I'm in a very similar position to learning these things and would appreciate your shared experience in this.  Looking forward to hearing from you.

But there will be Raspberry Pi 4 with newer revision codes, especially to faulty USB-C design on Raspberry Pi 4 which makes only specific USB-c cable works.

They usually get pushed out very silently (with the newest batch) so... maybe? You got a point but it's really not that big of a chance like the first few Pi models. (B - B+ kind)

But usually it's more stable (depending on what the revision) and is what @KD6-3.7 waiting for.

Additionally, it's not pushed out silently because Raspberry Pi have good documentation of all revision codes along with the changes.
The real problem is seller don't know the revision code or don't bother post the revision code.

Yeah, with wait I meant for more stable and bug fixed version 4. Thanks for advice. Will keep you updated. For now I will order 1TB SSD and sync on that spare laptop. Tomorrow I'm sitting down to Linux course. WML  Wink

Had to step away for a bit due to travel and now finally getting back to the Rpi 4 full node mission.
Wow, what a difference downloading core to an internal ssd on a good computer makes! Finished in 20 hours!  Was expecting at least a few days from my previous experience.
I should have it copied to an external HD and running on the Rpi shortly.  Fingers crossed.

Can I mirror my trezor wallet on Bitcoin core? Perhaps a watch only wallet.  I'm not intending to use the synced wallet for new transactions quite yet since I'm familiar with the trezor.

Yes...With a but....it's not that simple.

1) Run the Trezor back end. https://github.com/trezor/blockbook

2) Connect the back end to your Bitcoin Core node

3) Use custom back end in option in the Trezor Web Walett and connect to your backend

So...Yeah, it can be done.

you can also use Bitcoin Core team's HWI: https://github.com/bitcoin-core/HWI

guide here: https://github.com/bitcoin-core/HWI/blob/master/docs/bitcoin-core-usage.md


There's a big change to how the wallet sub-system works that's probably going to make it into Bitcoin 0.20.0, at the moment creating a watching wallet is pretty painless (although it will take a while to scan the blockchains for tx history), but spending using Bitcoin's GUI isn't yet possible. Continuing to use the separate Trezor apps is still the only way to do it (or use the cli tools for HWI)

Ultimately though, using Trezor's web wallet as the front end is less satisfactory as a solution than using an integrated tool with Bitcoin's GUI, both for how streamlined the process and how secure/minimal the system will be. But the earliest possibility of using that is gonna be 0.20.0, and that's not scheduled for release till May 2020. The watch-wallet scanning may well receive a big performance boost with BIP157-based utxo querying. Again, that'll be in 0.20.0 at the earliest (but you can enable the filters for BIP157 now if you're using Bitcoin 0.19.0+)

Ok, so for now I did downloaded a blockchain on that spare laptop using a newly purchased 1TB Samsung SSD. It took around 26-30hs which is amazing. Re-syncing after a night off takes only several minutes which is dope. To learn how to do it I watched those tutorials:
Linux - https://www.youtube.com/watch?v=bju_FdCo42w&list=PLtK75qxsQaMLZSo7KL-PmiRarU7hrpnwK (watched till like 34-35th video)
Full Node - https://github.com/k3tan172/ubuntu-node-box/ - only installed Core for now. Haven't setup incoming connections, TOR or anything yet since I'll do it when I migrate to RPi.

RPi is a project for this or next month so I will update you guys on specs I will decide on and on learning/progress.

Thanks for all the help Smiley

I know it's been discussed before in the thread, but I just came back to my office from one of my clients that has an embedded device that was dead. It is nothing more then a Pi in a case in the back of their id scanner.

Cause of death...a power adapter that probably cost less the then the $0.25 I put in the parking meter in front of their office because it's raining and I didn't want to park in the free lot and walk.
Seriously, I put in a phone charger that I had in my trunk and they were back online. I cracked open the dead one and it was so poorly constructed I was surprised it ever worked.

the RPi 4 even has a special new disk-over-USB protocol to make SATA work better than it did with the RPi3.

so I got this detail wrong

What we want is a USB SATA caddy that uses the UAS standard (sometimes called UASP, and stands for USB Attached SCSI). This allows the OS to issue ATA commands over the USB interface, which ordinarily USB does not handle.

This gives you:

  • the TRIM command, only used with SSD storage
  • improved random IOPS performance, as low level commands sent to the disk can be queued, instead of issued sequentially

The full performance of a direct SATA interface still isn't quite possible, but it's negligible for use with these single-board devices where the CPU is by far the more oft-encountered performance bottleneck.

Bascially, you can ditch the slow unreliable SD card for everything except /boot, and I think in the case of the RPi4 even that partition can be on an SSD and SD cards are entirely unneeded. I was wrong though that only the RPi4 can do this, any RPi should work with a UAS based external disk caddy. You just need an operating system that's new enough to talk UAS (which should be everything modern, it's kind of an old standard that took a long time for manufacturers to support, there aren't many UAS disk caddies available on the market)

I've downloaded core 0.19.0.1 files and extracted them to my Rpi desktop but I'm having trouble running bitcoin-qt. The readme files point me to run bin/bitcoin-qt but when I click it ask me which application I want to use and gives a list of options that don't seem right.  What do I do to run this or get core setup?

Looks like you attempt to open the blob/binary of bitcoin-qt. What you should to are :
1. Make sure bitcoin-qt have execute permission (right click bitcoin-qt from your file explorer and see option to make it executable)
2. Try to run it with command

Code:
cd /path/to/your/bitcoin/qt/file
./bitcoin-qt
