Anyone can hack IoT - Beginner's Guide to Hacking Your First IoT Device

By Andrew Bellini

Staying Safe

• Never work on high voltage (120v/240v)
• Never used damaged or modified power supplies
• Power off circuits when not in use
  • Easy to bridge something accidentally and cause a short circuit, bricking the device
• Watch out for large capacitors
  • They can be charged for awhile after the board is unplugged
