BioAmp EXG Pill

The BioAmp EXG Pill is coming soon to Crowd Supply:

Professional-grade analog front-end amplification for ECG, EMG, EOG, and EEG biosensing on one tiny board

BioAmp EXG Pill is a small, powerful Analog Front End (AFE) biopotential signal acquisition board that can be paired with any 5 V Micro Controller Unit (MCU) with an ADC. It is capable of recording publication-quality biopotential signals like ECG, EMG, EOG, and EEG, without the inclusion of any dedicated hardware or software filters. It’s small size allows easy integration into mobile and space-constrained projects, and it’s powerful noise rejection makes it usable even when the device is close to the AC mains supply. Any 1.5 mm diameter wire can be used as a strain-relieving electrode cable, making BioAmp EXG Pill very cost-effective in comparison to other options.

Data Fitness Connector (DFC) update on Crowd Supply

New update for the Data Fitness Connector (DFC) on Crowd Supply which wirelessly connects your Peloton bike to third-party apps, fitness watches, and more:

The DFC Build Process by Jason V

At this point we’re about two thirds of of the way through the campaign, and we’re very excited to report that we’ve hit our funding goal! Thank you!

This week’s update is for the curious minds out there who like to see how things are made. We’re taking you behind the scenes for a look at how early prototypes were put together. The final version of DFC will be made by our manufacturing partner here in the US, but we needed to build a few ourselves so we could test them before ramping up production.

In the time-lapse video below, you can see how a prototype DFC circuit board was built, starting with the application of solder paste atop a stencil, followed by the careful placement of all those tiny little components that make it work. After that, the board was placed in a circuit oven (kind of like a fancy toaster oven), which melted the solder paste and secured everything in place.

Building circuits by hand in this way is an odd mix of calming concentration and frequent frustration, so we’re happy to hand this off to a robotic pick-and-place machine for mass production.

Data Fitness Connector (DFC)

Free Your Cycling Power & Cadence Data!

The Data Fitness Connector (DFC) data broadcaster is a Bluetooth device that allows Peloton bikes to communicate with fitness watches, head units, and apps—a feature that’s not available on stock Peloton bikes. It reads power and cadence data in realtime, through a cable connected to your bike, and broadcasts them to nearby devices, including those built around non-Peloton platforms like Zwift and Garmin. This allows you to enjoy the built-in functionality of your bike while simultaneously utilizing features and services that depend on third-party platforms.

Who Wants to Ride a Bike in Walled Garden?

Interested in the fitness data you produce? Want more control over who else has access to those data? Prefer not to be locked into a particular platform? If you have a Peloton bike, then DFC is for you.

PiMod Zero: Raspberry Pi Zero RF Video Modulator

We excited to see this Raspberry Pi Zero RF Video Modulator on Crowd Supply:

PiMod Zero

Dust Off That Old TV

PiMod Zero brings old tech back to life by allowing a Raspberry Pi Zero to display color or B&W video – and play audio – on vintage televisions. It provides a super-compact way to watch old movies, play retro games, present digital art, or navigate your operating system using any television that receives standard NTSC broadcasts on VHF channels 2 and 3 (55.25 MHz and 61.25 MHz).

In the past, you would have needed a cumbersome RF modulator box to adapt the HDMI signal from a Pi Zero. Now, with this convenient HAT snapped on top of your Pi Zero, no additional dongles are required. In fact, once the Pi is powered up, the only other cable you need is a piece of coax to connect PiMod Zero to your TV.

Configuring the Raspberry Pi to output composite video and stereo audio to PiMod Zero is extremely simple. Handy scripts and thorough documentation will be available in our GitHub repo.

This allows you to enjoy the built-in functionality of your bike while simultaneously utilizing features and services that depend on third-party platforms.

One of our goals for this project is to make it easier for hobbyists to design and build hardware that interacts with fitness machines, which is why we’re offering a Maker Edition of DFC. Sure, if you’re trying to start the next indoor fitness revolution, you probably have your own hardware team. But what if you just want to crank up the music and cue some heroic lighting when you hit your pace? Or progressively inflate a balloon so you know your workout’s over when it pops? DFC lets you bring your quirky idea to life and take it for a ride on the handlebars.

Or you could do something practical! If you must. Add a dedicated display and use it to chart realtime metrics that Peloton doesn’t display. Or log your raw data offline for the last word in platform independence. Or attach an array of sensors and see how your performance is affected air quality, humidity, and other indoor environmental factors.

The nRF9160 Feather Is Now Served

Jared Wolff has design a Feather form factor board with the nRF9160:

The nRF9160 Feather Is Now Served

Low-power shutdown, built-in 4FF SIM card slot, flexible power supply, and more.

I was a complete failure. My prototype wasn’t working. I spent at least an hour trying to rework a frustratingly large LTE module on an impossibly small circuit board.

It wasn’t going to work.

So I went back to the drawing board. I poured my years of hardware experience into a tiny form factor.

The end product?

Something smart. Something with LTE, NB-IoT, and GPS. Something anyone could get started with right away.

And thus, the nRF9160 Feather was born.

I need your help! 🙏

To make this campaign a reality, I need your help to meet our minimum order quantity of nRF9160 Feathers. Without that, we’re dead in the water! Head on over to the campaign page to reserve yours.

For those of you who’ve already committed, I thank you from the bottom of my heart. I can’t wait to get the nRF9160 Feather into your hands!

P.S. Huge thanks to Hackster and GroupGets for making this happen. You guys and girls are great. ❤

iCEBreaker FPGA: new video streams and new content

https://twitter.com/esden/status/1249917248795340800

An update from our Dorkbot PDX friend, Piotr Esden:

iCEBreaker FPGA: new video streams and new content

iCEBreaker Production

As you read in our last update in November, we finished fulfilling the campaign, but that does not mean work on iCEBreaker has stopped. We keep producing iCEBreakers and Pmods to keep 1BitSquared US and 1BitSquared DE, as well as Crowd Supply and Mouser, stocked.

For those of you who are patiently waiting for your shipments, don’t worry. A package with additional inventory is going out to the Mouser warehouse today!

Continuing Work on iCEBreaker

We are continuing work on new examples and additional iCEBreaker hardware. If you are not following 1BitSquared or Piotr on Twitter, you might have missed some stuff that Piotr is working on. Since January, Piotr started streaming on Twitch on a fairly regular basis. You can follow him on Twitch and be notified every time he goes live. Piotr is also announcing upcoming streams at least a day in advance on Twitter as well as on the 1BitSquared Patreon page.

As a result of the Twitch streams, we’ve had a few interesting new developments for the iCEBreaker platform. A few weeks ago, we published Litex RISC-V SOC generation examples that you can find in the iCEBreaker GitHub Organization. Piotr gave a Twitch stream presentation about the build system and how to use it. You can watch the stream Archive on Twitchdiode.zone, and YouTube. This example gives you the foundation to create your own SOC for the iCEBreaker, start adding your custom hardware to the RISC-V core, and program it in C or Rust. We are also working on MicroPython and maybe even CircuitPython support in the not too distant future.

Upcoming Twitch Stream

Piotr has scheduled a Twitch Stream for Tuesday, April 13th, 2020 at noon PDT. He will be working on a new Pmod for the iCEBreaker that will allow us to connect NES or SNES controllers from two very popular 8-bit game entertainment systems. 😉 That same Pmod will also contain a stereo audio output. This Pmod together with a DVI output, LED Panel output or VGA output will be an ideal combination to recreate old or build new custom game consoles and a wide range of emulations, for entertainment, preservation, and education.

electronics-lets-play-stream

If you are curious when the stream will happen in your timezone you can either check on Twitch itself, as there is a countdown timer till the next stream below the video streaming window, or you can check timeanddate.com.

Keep Supporting our iCEBreaker work

If you like to see continuing work and content creation for the iCEBreaker platform, and you already have all the hardware you need, then consider supporting us through Patreon. We keep adding perks for Patrons, like KiCad panel templates and behind the scenes news. We have a few very generous supporters that make the Twitch streams possible, but any additional support is appreciated.

Stay in Touch

And don’t forget, the continuing development and support for iCEBreaker keeps on rolling on the 1BitSquared Discord server, and iCEBreaker forum! So join the fun and show off your iCEBreaker projects! 🙂

Stay safe and healthy,
Piotr and Danika

CircuitBrains Deluxe

Easily Add a Powerful Microcontroller To Your Next Project

CircuitBrains Deluxe is the smallest soldererable ATSAMD51 module. Skip on all the tedious work of adding a 32-bit microcontroller to your next project. We’ve taken care of the tough work of pin mappings, power & decoupling layout, clock, flash, assembly, bootloader, and firmware. All you need to do is drop a footprint into your next PCB design project, connect your peripherals and USB connector, then solder it on and write your code.

Just Solder It On

Save time and frustration on your next project. We’ve taken care of the finicky fine-pitch surface mount assembly for you. CircuitBrains comes in an easy-to-solder castellated module format. You can either incorporate it into your project PCB design, or solder wires directly to it via the extra holes in each castellated pad. We’ve also made it easier to hand solder these modules by including a larger “hand solder” PCB footprint for your design.

Add Some Power to Your Project

The core of CircuitBrains Deluxe is the Microchip ATSAMD51J19 32-bit ARM Cortex M4 microcontroller, which can run up to 120 MHz. In addition to a powerful microcontroller, each CircuitBrains Deluxe module has 8 MB of Quad SPI flash onboard. You’ll have plenty of space for your project code and media files.

Easy to Program

CircuitBrains comes preloaded with CircuitPython. Who doesn’t love Python on microcontrollers? Plug your device into USB, modify your code, and see the changes take effect as soon as you hit Save.

Small Form Factor

CircuitBrains Deluxe won’t take up a lot of space. It was designed to be used in small projects. At just over 1 square inch (29 mm), there aren’t many places this thing won’t fit into.

Open Laptop Soon to be Open For Business

How better to work on Open Source projects than to use a Libre computing device? But that’s a hard goal to accomplish. If you’re using a desktop computer, Libre software is easily achievable, though keeping your entire software stack free of closed source binary blobs might require a little extra work. But if you want a laptop, your options are few indeed. Lucky for us, there may be another device in the mix soon, because [Lukas Hartmann] has just about finalized the MNT Reform.

Since we started eagerly watching the Reform a couple years ago the hardware world has kept turning, and the Reform has improved accordingly. The i.MX6 series CPU is looking a little peaky now that it’s approaching end of life, and the device has switched to a considerably more capable – but no less free – i.MX8M paired with 4 GB of DDR4 on a SODIMM-shaped System-On-Module. This particular SOM is notable because the manufacturer freely provides the module schematics, making it easy to upgrade or replace in the future. The screen has been bumped up to a 12.5″ 1080p panel and steps have been taken to make sure it can be driven without blobs in the graphics pipeline.
