ATTINY85 IOTA SEED Management

DIY Build of IOTA SEED Management consists of the components:

• USB-Case as a 3D Print
• ATTINY85 Digispark USB Board
• (Optional Photoresistor)
• Arduino Development Environment with ATTINY85 drivers (http://arduiono.cc)
• 2 Versions of Code
• 1. Plug & Play needs only the board, add the one Seed in the code and compile (Community edition)
• 2. Nine (9) Seed Version needs some small assembly of a Photoresistor and some work, provided by a Youtube video (tbd>)

Plug and Play Version

Overview:

1. Assembly

• Place the Board into the USB-Case (3D-Print).
• Doubleclick on the INO-File and open it.
• place your SEED into the 1st line of code (new SEED can be created here)
• compile code
• upload the code to the USB Board and add the Board to the USB Connector

2. Useage

• Open your IOTA Wallet
• place the cursor to the SEED entry
• add the SeedStick
• SeedStick fills in the SEED
• Remove the SeedStick (dont't forget)
• Only at 1st Useage: write the 3 letter shortcode (Wallet output) of the SEED onto this new build SeedStick case (to identify which Stick is the right one if there are several)

3. Problems

• if you add the SeedStick the SEED will be placed anywhere where the cursor is located
• Be always sure that your cursor is where the SEED should be inserted.

4. Safety

• Add the SeedStick to insert the SEED, remove the SeedStick immediately
• Keep complete Github repository and Arduino INO - Files on a USB-Stick and execute:
• 1. download and run Arduino from a USB Stick
• 2. then close your network
• 3. add SEED to code
• 4. compile and upload code to SeedStick
• 5. remove SeedStick and close, remove the Arduino environment incl. USB Stick
• 6. connect, open to your network
• 7. open IOTA Wallet, place cursor to the SEED entry
• 8. test and use it: stick the SeedStick to a USB port and wait 1-2 seconds to fill in
• 9. remove SeedStick
• Be happy
