**The RaspiBlitz is a all-switches-on Lightning Node based on LND running together with a Bitcoin- or Litecoin-Fullnode on a RaspberryPi3 - with a 1TB HDD and an nice Display for easy setup & monitoring.**
Its mainly targeted for learning how to run your own node decentralized from home. Discover & develop the growing ecosystem of the Lightning Network by becoming a part of it.
Its mainly targeted for learning how to run your own node decentralized from home. Discover & develop the growing ecosystem of the Lightning Network by becoming a part of it. Build it as part of a [workshop](WORKSHOP.md) or as a weekend project yourself.
Variation: If you dont have a big bugdet to prefinance the part shoppings or people have already hardware they want to bring to can just buy the HHDs and SD cards and prepare them to run this scenario.
## B) Bring your own Hardware
Estimated Duration: 4 hours
Estimated Duration: 4-6 hours
This scenario is just adviced for small groups or you need to bring multiple blockchain copy stations - see details on "Prepare HDDs with Blockchain Data". Otherwise it needs the least prepartion time and prefinance and can be announced about participants 5 days before, so that they have time to order all the parts online.
* Instruct Participants to bring Hardware
* Prepare Blockchain Copy Station
* Setup Workshop Environment
* [Instruct Participants to bring Hardware](WORKSHOP.md#instruct-participants-to-bring-hardware)
Make sure that as early as the participants arrive at the workhop location to check their hardware list and even before official starting time take their HDDs and start the blockchain copy process.

Make sure you have the following Hardware and Infrastructure ready for the workshop:
* Lots of 'multiple power outlets/extensions' (min. 2 per participants - RaspiBlitz +Laptop)
* Network-Switch with enough ports (min 1 per RaspiBlitz)
* Enough LAN network cables (short ones to connect the RaspiBlitzes)
* Good internet connection at location with LAN port (or a WLAN to LAN adapter)
* Extra WLAN Router (if you are not sure if LAN & WLAN is not on the same network at location)
* One or two USB SD card adapters
* One or two USB-C to USB-A adapters
* Some Tape, Marker & Pens come always handy (also for participants to wirte down seed & passwords)
* And eventually some Bitcoin funds (if people dont have their own to start small funding channels)

Basically you follow the assemble instructions on the RaspiBlitz GuitHUb README. Think of a safe way to transport the assambled devices to the workshop location - HHDs like it soft.
# Prepare HDDs with Blockchain Data
## Prepare HDDs with Blockchain Data
This is the most time consuming part of the preparation. Try it once to get a feel for how much time you need to prepare one HDD.
A prepared HDD is formatted in EXT4 and named "BLOCKCHAIN". In folder called `bitcoin` it contains a copy of the following data folders from a running Bitcoin core client (same version on RaspiBlitz).
```
/bitcoin/blocks
/bitcoin/chainstate
/bitcoin/indexes
```
optionaly you can add also the testnet data:
```
/bitcoin/testnet3/blocks
/bitcoin/testnet3/chainstate
/bitcoin/testnet3/indexes
```
The bitcoin core client the folders are from needs to have `txindex=1` in the bitcoin.conf and needs to be stopped while the data is copied to the HDD.
