It is 2:30 AM. Approximately half an hour ago, I plugged in the Pendant prototype and uploaded some code. And it worked flawlessly.
Right now, sitting in front of me, I have two prototypes: The DigiBadge V2 Mini, Revision 3B, and the LED Matrix Pendant, Revision 5. Both of them required a little work to get working, but Revisions 3C and 5B address these minor issues and will, unless something goes terribly wrong, be the production revisions of these boards.
Now, as a picture is worth a thousand words, I’ll show some:
Oh, but wait! There’s a video, too!
Now that you’re all oogly-eyed and slackjawed, I’m going to go over just how you can get your hands on one of these.
First up, a pricing breakdown:
The DigiBadge costs $15 USD. This does not include an SD card or any of the special art seen above. The DigiBadge is designed to be a Digital Color Communications Badge (For more information, see this BronyCon blog post), and it’s been trimmed down as much as possible to be as affordable as I can make it. However, it comes preloaded with code to take advantage of any inserted SD cards with properly formatted images on them, and can play them in a Slideshow mode (As shown in the video above), or as a still image with manual cycling, in addition to the DigiBadge functionality. I’ll be writing a post on all the features of the DigiBadge in the next few days.
The “Art Cards” as I’ve been calling them, currently contain eight images: Six “Twilight and the Rainbooms” images (One for each of the Mane Six) by Trish Forstner, one “Flutterbat” image and one “Vinyl Scratch” image, both by LeekFish. These cards will be sold separately for an additional $10. They’ll be able to be simply slotted into the DigiBadge with no changes in code required. I’ll be giving more information on these art cards (And how they’ll change in the future) with the DigiBadge post. Never worry, though! I am a huge proponent of ensuring artists get fair and appropriate compensation for their work, so the more of these sold, the more money they make as well.
The Pendants will be selling for $10 and will come in one of a few pre-programmed varieties. The Pendant is designed to be modified and changed by the user – If you’ll take a look at the images of the Pendant above, you’ll see numerous pins broken out. Every one of the ATMega328’s pins are broken out, including 3 Ground and 3 5v pins. Additionally, as the matrix driver is an I2C device, the only restriction on pin usage is that I2C address 0x70 is in use.
All three of these items will be available for pre-order within the next few days. Pre-orders will have the option to pick up at BronyCon – This will be the earliest possible to get them! Currently, my focus is on making everything for the convention, so any orders that need to be shipped out will be shipped after the convention. At this point, I’m not 100% sure when that’ll be, but I’ll be sure to keep you guys posted!
But for now, it’s almost 3AM, and I should be sleeping. If you have any questions, post them in the comments or hit me up on Twitter – Either at the Matchfire account, or on my personal account.
