I’ve had good experiences with them in the past, and since we were paying for DHL shipping to California, we were pretty confident the boards would arrive on time. We went with Seeed’s Fusion PCB service to make the actual PCBs. This badge had to be designed and fabricated on a very short timeline, but I like to live dangerously. We also picked up a few multicolor flashing RGB LEDs for extra special glowy blinky stuff. Since Tindie’s eyes are different colors, an assorted kit of 5mm LEDs was the best way to go. The battery holder came from Digikey, and holds a 1216, 1220, or 1225-sized lithium cell.Īmazon Prime is a godsend, and this is what we used to source the LEDs and batteries. I don’t really trust AliExpress datasheets, and if I’m building a board around a battery holder, I need to get the dimensions and pads right the first time. The battery holder was the most difficult part to source. That’s one order down, and about a fifth of the parts on the BOM. We’ll need bags to contain all these parts, and conveniently this AliExpress store also sells self-adhesive bags to put the board, LEDs, battery, and all the parts in. These ‘badges’ would actually be lapel pins, and we can get hundreds of them from the same AliExpress store used. With a somewhat cogent idea of what this badge should be, most of the BOM was already sorted. There’s only one way to find out if this will work. Anyone can get a PCB with a blue soldermask, but I haven’t seen any experiments exploring the artistic potential of Chinese board house PCBs. However, the Tindie mascot is blue, not purple.
and are also doing incredible work with OSH Park PCBs. A few months ago, made money of me using different layers of mask, silk, and copper on the standard OSH Park PCB stackup. This is an experimental board, although we’ve seen projects similar to this before. The PCB must fit inside a 50 mm x 50 mm square to get the best pricing from the board house, and the entire top layer, including the copper, would be art. The circuit would be very simple - just a 3 V, 1220-sized battery and two LEDs - and a pad for the lapel pin clasp on the back. We would build a badge in the shape of the head of our lovable robotic mascot, with LEDs for eyes. discovered ‘butterfly clutch tie tacks’ are effectively SMD components.īetween those two ideas, and I eventually came up with a workable idea. However, just a few days before these plans came to fruition, I stumbled across an entirely new idea in wearable PCBs. The Tindie robodog head, using colors taken from a standard blue soldermask PCB. It’s the perfect introduction to soldering irons. Since we’ll be hanging out at the Hardware Hacking Village - the largest concentration of soldering irons in Vegas this week - an, ‘I can solder’ badge an awesome idea. The first suggestion from was a simple ‘I Can Solder Badge’, or something like what Partfusion is selling on Tindie. This is obviously not going to be a complicated badge, but in the space of simple badges, what can we actually do with two weeks of development and manufacturing time? That gives this project only two weeks from conception to design to kitting badges, to physically lugging them over to the con. It’s almost easy, and there are zero excuses for anyone not to develop their own hardware badge for next year’s con. Is this even possible? Surprisingly, yes. That gave us barely more than two weeks to come up with an idea for a badge, design one, order all the parts, wait on a PCB order, and finally kit all the badges before lugging them out to DEF CON. Obviously, this means we need our own unofficial DEF CON badge.

We’ll be showing people how to solder, fixing badges, and generally being helpful to the vast unwashed masses. We’re sponsoring the IoT village, - the high priestess of Tindie - and I will be spending some time in the Hardware Hacking Village, praising our overlords and saying the phrase, ‘like Etsy, but for electronics’ far too much. This is also a banner year for the Hackaday / Tindie / Supplyframe family at DEF CON. We’ve already taken a look at Bender Badges, BSD Puffer Fish, and the worst idea for a conference badge ever, and this is only scratching the surface.
For the last few years, independent hardware wizards have been creating and selling their own unofficial badges at DEF CON, but this year it’s off the charts. DEF CON is starting right now, and this is the year of #badgelife.
