Don’t forget that Sunday, 10/23, we have two back-to-back excellent workshops at Resistor: Alexis’s HTML5/CSS3 deep-dive workshop (sold out), followed by pumpkin hacking for Halloween.

The pumpkin party starts at 4pm. Please register (free!) on Eventbrite to RSVP. We’re thinking circuits, laser cutting, and maybe more.

We have a very small number of pumpkins available, along with cutting tools. Please BYOPumpkin. If you’ve got orange or purple LEDs or weirdo electronic components (or UV LEDs?!), bring those. We wouldn’t say no to contributions of snacks or tasty libations, either.
