(Optional) Change hostname to “definode” with “sudo raspi-config”

Standard hostname is raspberrypi. You can change the name to definode to be able to enter the wallet in your browser with http:\\definode:5050 instead with http:\\raspberrypi:5050

• Open terminal
• Enter sudo raspi-config
• Select System options
• Select Hostname
• Change it to ```definode``
• Exit with OK
• Reboot

Remote control VNCViewer

• Download and install VNCViewer tool on your PC/Mac: VNCViewer
• DefiNode should be powered on and running
• Open VNCViewer

• Click "New connection"
• Enter the hostname of your DefiNode in "VNC Server". If you changed it to definode, please use this. raspberrypi is the standard hostname. You can also enter the local IP address, you've written down, as mentioned above.
• Klick OK
• Double click the new connection

• enter pi as username
• enter the password you gave the DefiNode at the first boot
• press OK and you should see the DefiNode desktop

Now you can connect to it any time from any device and mage it conveniently.

🎉 Congratulations! You've done a very good Job so far! 🎉

🎉 You can now disconnect the external Monitor, mouse and keyboard and proceed work with the Remote Desktop 🎉

Download script and execution

• Open a new terminal Terminal

• Enter: this command and press ENTER

git clone http://github.com/definode/definode && cd definode && sudo sh setup-build-definode.sh

🎇 #Watch the magic happening (for ~3h) 🎇

I know its long but this is really necessary to ensure you build the official software from DeFiChain on your DeFiNode.

• Steps done in the background:
  • Downloading and installing the official DeFiChain software. Nothing is changed and 100% original source code is downloaded
  • Downloading the latest blockchain snapshot (no 100% sync needed after installation)
  • Start DeFiChain and wallet

There may be some orange messages appear in the terminal, but this is nothing to worry about.

First Wallet usage and test

When everything is finished and running you will get the message "Please open your browser http://localhost:5050" in the terminal

• Open the chromium browser on your DeFiNode and enter http://localhost:5050 -> press enter

• You can also use your PC/Mac/Mobile phone browser (when in same LAN) and enter the IP Address (or hostname) + Port to remote control the Node from other devices. I.e. 192.168.0.236:5050 or http:\\definode:5050 -> press enter. You can bookmark this in your browser.

For advanced use, like backup / restore wallet, master nodes, blockchain explorer... please check the FAQ and troubleshooting guide below.

🎉 Congratulations! You've successfully installed the Defichain software on your DeFiNode 🎉

2. 3D Printing

All files can be found in the 3D files folder. Every part was specifically designed for 3D printing and can be easily printed with every FMD printer.

My preferred material and settings:

• PLA
• 0.4mm nozzle
• Temps depending on the brand you are using

Slice files

Use your favorite slicing tool.

I recommend using raft for:

• The top part
• The mid part

Rest of the parts can be printed directly on the plate.

Use higher quality settings to have the best looking DefiNode.

Add support where the slicer recommends

After the print, clean everything very good and remove the support.

NEW! Order your DefiNode case online

Check out the new printing service by Gabriel Kunzer https://www.gabrielkunzer.com/definode/. You can order your case in many colors! Great service! 🔥

3. Custom Case assembly

If you successfully finished step 1 and the wallet was running in the Raspberry you can now start assembling the DefiNode. Please clan the 3D print as good as you can. You can use a cutter knife to remove support or other unnecessary remaining.

Shutdown via VNC (not just power off) your Raspberrypi. Remove all connections and USD stick.

Put Raspberry into case

• Use a soft material table pad on the table if possible.
• Slice in the Raspberry connectors first
• Press the back side very gently in to the hocks.

That’s it, no screws, nothing. Easy, isn't it!

Cut grids and insert

Prepare scissors, cutting template and the flexible fan grids you've purchased from Amazon.

• Use the template to cut two fitting grids
• If it will not fit right away, you can trim them later on

• Make sure the slots are clear very clear, so you can easily insert the grid.

• Check the orientation and slide in the grid. This should go very smooth.

Connect PSU

• Slide the cable in like in the picture below
• Connect the USB-C connector to the raspberrypi

• Flip the case und put the power cable into the strain relive and hole at the back.
• Make sure the power switch is outside the case

Assembly of the bottom

• Here you can add a SSD if you want too.
• Make sure the bottom is oriented like in the picture. I will not fit otherwise!

• Put the mid part on top
• Make sure the locking mechanism aligns 100%
• Slightly press down the mid
• It should slide and lock pretty smoothly. When not, check for 3D printing remaining and remove them.
• Always make sure the cables align

Connect and assembly Fan

• Prepare the fan and two jumper cables (male -> female)

• Connect both to the Black and Red wires on the Fan connector (yellow is not needed). I dosn't matter what colors the jumper cables have.

• Connect the jumper cables according to the picture
  • Red cable goes to Pin 2 on the Raspberry
  • Black cable goes to Pin 6 on the Raspberry

• I should look like this (don't pay attention to the green, yellow and orange jumper. Those are for the LED ring and will be described later)

You can switch on the Raspberry without the USD Stick to test if the fan is running.

If you want to add the LED Ring jump to chapter 4 and come back here, when this is finished.

• Insert Fan exactly like in the picture. You can bend the jumper cable so the fan will not hit the when rotating.

• Organize the cables and insert the air guide like in the image below. Make sure the air guide is flat on the fan and has a good fit. If not, check if the cables are proper organized.

• Check again if the fan is working by powering on the Raspberry without the USB Stick.

• You cannot close the DefiNode by mounting the top. Make sure it aligns and press is slightly down.

• If you have to open it again, you can use a big screwdriver or a 5ct coin or similar.

Final Assembly (USB Stick and Network cable)

• Connect the LAN cable
• Insert the USB Stick

Power on

• You can now power on the DeFiNode and process with using the wallet a described in chapter 1.

4. Bonus (only for advanced users with soldering iron) not essential for operation, but very cool.

If you want to make your DeFiNode even cooler, you can add a RGB LED Ring to it. The Ring can be programmed to show any animation you want. For now a pink circle indicates the DefiNode is running.

As in the shopping list, you need to get one RGB LED ring and 3 jumper (female -> male) cables (you should have them already)

[x] LED Ring amazon link

What you need:

Soldering

Solder the male side of the jumper cable only to:

• DI pad
• 5V pad
• GND pad

DO pad is not needed here. Color of the jumper cable is not important. As long as you do the Raspberrypi connection properly.

Now it should look like this

Assembly LED ring

• Mount the ring as in the image below. Don’t use too much pressure, you may break off the hock.

Connect LED ring (right after step 3.c)

Install LED script and auto start it

(TBD) but check the txt on GitHub

LED (rainbow) test and usage (in development)
