The Pixel 2.0 is a tiny OLED screen for your wearable Arduino pleasure

March 3rd, 2017 Comments off


The tiny Pixel 2.0 is basically an Arduino board wedded to a tiny 1.5? 128×128 color OLED screen. This means you can stick it inside a wearable and address the screen directly from the Arduino board, an improvement on current “solder the screen to the Arduino and hope it works” world of DIY electronics.

This teeny-weeny board costs $75 on Kickstarter and should ship in June. It’s completely open source so you can dig into the schematics, build your own, or generally do whatever you want with it. An on-board SD card slot lets you store data like games and videos and you can program graphics to the screen using the Arduino SDK.

The Pixel 2.0 has surpassed its goal of $5,000 so it’s ready to ride.

This is the second version of the Pixel created by Rabid Prototypes of Boston. They also make a nice high speed Arduino board called the Neutrino and offer lights, motors, and other gadgets for your DIY funhouse. I’d love to see a micro arcade game running on one of these things and, given the acceptable pixel density, it sounds like it just might work.

Any headphones can be Bluetooth headphones with Jack

February 27th, 2017 Comments off


When Apple decided to strip its flagship phones of the headphone jack, certain people were angry. Those relying on the headphone jack for non-music things were grumpy, but so were those of us who had recently dropped hundreds of dollars on new, high-end headphones. Jack — a Kickstarter campaign in its final hours — offers reprieve to both groups.

The product is made by Podo Labs, which you may remember from two different stickable Bluetooth cameras, both funded very successfully on the Kickstarter platform, too.

“We were on the Highway1 accelerator,” Eddie Lee, Podo’s co-founder, tells me, and we’re doing a lot of work developing our own Bluetooth stack. When Apple announced they were going to remove the headphone jack, we looked at each other and thought — well, that’s something we can help with.”

The result is Jack. Jack is a simple Bluetooth device that helps music and podcasting fans reconnect with their phones, even if the headphones they love are encumbered with the ancient technology of “wires,” on which Apple so courageously declared its violent putsch.

I may have slightly disassembled Podo's Jack when I met the team. Whoops. Sorry, guys.

I tried out the Jack last week, and it delivers on its promise. Crystal-clear sound, easy to pair and the device is designed to be unobtrusive. The metal clip encircling its case could be mistaken for a tie clip. If anyone in the café where we met would have worn a tie, that is. Either way; design-wise, it’s simple and understated.

“We’re hoping to sell Jack at $39, eventually,” says Lee, “but for the Kickstarter campaign, we’re selling them for $29.”

The Jack has a couple of cool tricks up its sleeve, too. The Podo crew tells me you can hook several of them up to each other wirelessly, connecting them to several sets of headphones or speakers. Perfect for creating a tiny silent disco experience, I suppose.

“In theory, we can hook up an infinite number of Jacks to each other,” Lee says, before admitting that they’re not yet able to consistently do that. “On the Kickstarter campaign we are selling two of them as a buddy pack, because we’re able to get two Jacks to connect and work well consistently. We are optimistic about being able to do more than two, eventually.”

The Jack can work both as a receiver and a transmitter. The case for the latter is to add Bluetooth functionality to devices that typically don’t have it — televisions, for example.

I feel that Podo’s biggest challenge is going to be defending the price-tag; $39 may be worth it if you have a $500 pair of headphones you can’t use otherwise, of course. Nonetheless, there are cheaper devices already available — convincing customers to shell out more money may be a hard argument to make, even if Jack does prove to be higher quality with better battery life and snazzier design. That hasn’t stopped more than 15,000 people from backing the Kickstarter campaign with more than three-quarters of a million dollars so far, though, so what do I know.
