Meetup Descriptions

Some HHV Challenges

By Rob Rehr


HHV members have created a few challenges for this year’s Hackfest. Come learn and chat about those challenges, or bring new challenges to share with the community. This time will start with an introduction to this year’s HHV challenges, but the remaining time will be open to community questions and conversations

PCB Rework

By Ben Gardiner


Have any tips for how to make your own use of a PCB? Do you love bodge wires? Should they be blue? Join us for these and other pressing questions around the topic of PCB rework.

3H: Hardware Happy Hour

By Rob & Ben & All


Wind down the first official day of HF talking about hardware! Bring a project to share! All hardware projects are welcome, from a simple Arduino based thingamabob to your company’s newest hardware product (and how you earn your living). The main focus is meeting like minded people who are building fun things!

Badge Hacks

By Rob & Ben


Badges are cool and all, but they’re more or less glorified development boards. How have you modified your badges so that they do more than just collect dust? Bring a modded badge to show off, or simply join for inspiration!
