Open Hardware Summit badge: accelerometer demo

Want to use the KX122-1037 Accelerometer (datasheet) on the 2018 Open Hardware Summit badge?

Step 1:

Make sure that R12 and R13 are populated.

R12 and R13 are 2.2K Ohm resistors for the I2C bus. This is needed for the accelerometer to work. We mistakenly had DNP (do not place) on the BoM (Bill of Materials) for R12 and R13.

Awesome people at Artisan’s Asylum makerspace helped to solder these resistors on the badges right before Open Hardware Summit! 💜✨

It is possible that some badges were not reworked. Please email [email protected] if they are missing from your badge.

This photo shows what is will look like when R12 and R13 are missing:

Step 2:

Download the Python file named accelerometer.py from the ohs18apps repository on GitHub:

Start the FTP server and connect to the SSID listed on the badge:

https://photos.app.goo.gl/SKBWbUtKghszr9Ns5

Open your FTP client application and connect to 192.168.4.1:

After the transfer completes, power cycle the badge by removing the batteries and reinserting.

Press the left application button (with the paintbrush and pencil icons) to enter the menu. accelerometer.py should then be listed under Available Apps menu. Press the down cursor until accelerometer.py is selected and then press the application button again.

Step 3:

The KX122-1037 Accelerometer datasheet describes the 3 different axis:

Here are examples of the X, Y and Z axis of the accelerometer for reference:

X axis positive max

X axis negative max

Y axis positive max

Y axis negative max

Z axis positive max

Z axis negative max

Open Hardware Summit highlights by Leslie Birch

Great post by Leslie Birch about the Open Hardware Summit last week:

Five Awesome Tech Moments at Open Hardware Summit

Open Source Hardware Association (OSHWA) recently held its Open Hardware Summit in Boston. For me this is one of the few times during the year that I get to hear about open source hardware projects directly from creators and users.

It’salso a fine time to play with some tech on location and network with people that have the DIY bug. Public Lab was in the mix with Jeff Warren talking up his reverse engineered toaster design for OSHWA’s new certification process and Bronwen Densmore wielding the new community microscope kit.

The Open Hardware Summit is coming on Thursday, September 27th at MIT. OSH Park and Screaming Circuits are producing an electronic conference badge this year for the Summit. The badge features an e-paper display and an ESP32 microcontroller.

All 300 badges assembled by Screaming Circuits have arrived!

Thanks to Duane Benson and the rest of the team at Screaming Circuits for all the support on this project.

OSH Park is producing electronic conference badges for the 2018 Open Hardware Summit. The hardware has been designed Alex Camilo, based on concepts from the ESP trINKet by Mike Rankin. The badge features an ESP32 microcontroller and a 2.13″ E-Paper display.

OSH Park shared project for the Rev 3 by Alex Camilo :

We expect this to be the final revision.

Timeline:

It is ordered on Super Swift today and should be validated next weekend. This will allow us to order the full quantity PCB panels in August 13th. Assembly is estimated to be 10 business days from the day when all components and PCBs are received.

Rev 2 photos:

And for those interested, here is a link to a gallery:

Terminal output on Rev 2 prototypes:

The Rev 2 prototypes have NodeMCU boards soldered on to the back to serve as a USB to serial adapter.

One of the Rev 2 prototype boards that Alex sent me has the default e-paper demo:

The other has MicroPython installed! 🙂

Open Source Hardware Certification Logo is Official

Michael Weinberg writes on the Open Source Hardware Association blog:

Open Source Hardware Certification Logo is Official

We at OSHWA are excited to announce that the OSHWA Certification process has an officially registered trademark. This registration will make it easier for OSHWA to prevent people from using the OSHWA Open Source Hardware Certification logo if they have not actually gone through the certification process. We hope this will give the community more confidence when they see the OSHWA certification logo on hardware out in the world.

Ada Lovelace Fellowship deadline is April 30th

The application deadline is Monday, April 30th, for the Ada Lovelace Fellowship to attend the 2018 Open Hardware Summit:

Ada Lovelace Fellowship

The Ada Lovelace Fellowship was founded in 2013 prior to the annual Open Hardware Summit at MIT by Summit Chair Addie Wagenknecht and OSHWA Director Alicia Gibb as a way to encourage women, LGBTA+ and/or other minorities in open technology and culture to actively participate and foster a more diverse community within open source.

For the sixth year, we are excited to offer up to ten Open Hardware Fellowships to members of the community which includes a $500 travel stipend and entrance to the Open Hardware Summit.

By offering the annual travel and summit conference assistance to community members, the Open Source Hardware Association hopes we as a community can encourage more women, LGBTA+ and/or people of color to participate in open source. We have many strong leaders and speakers in our field and we personally want to continue the trend upward.
