As part of the certification program, OSHWA ensures that the definition of “open source hardware” used by a specific project (in our case in these 3 mini mechanical keyboards) matches the community’s definition of open source hardware. They provide a unique identification number (UID) for each version of the certified open hardware device based on the country code and a number. So now we have:
The prefix BG is the country code for Bulgaria, because all these mini mechanical keyboards are made in my hometown of Plovdiv, Bulgaria. As truly and entirely open source projects, we also go one step further. Only free and open source software has been used to design the printed circuit board, the stickers, the firmware, and the documentation. In previous updates we explained how we use KiCad for designing the printed circuit boards and the open source firmware QMK and KMK written in CircuitPython.
As part of the covered stretch goals, each kit will include stickers from ANAVI Technology and KiCad, the free and open source CAD software used for designing the printed circuit boards of the keyboards. Furthermore, ANAVI Macro Pad 10 kits will include 32 super-cool emoji stickers. You can stick them on the top or sides of the translucent keycaps. Last but not least, we’ll be publishing various video tutorials to ensure getting started is easy.
ANAVI Macro Pad 10, ANAVI Knobs 3 and ANAVI Knob 1 all come with gold-plated black printed circuit boards, Raspberry Pi RP2040 microcontrollers, USB-C connector and clickable rotary encoders. The popular open source KMK firmware allows you to easily program and configure custom keyboard layouts and macros using CircuitPython.
Do you remember our tiny keyboard with just 2 keys called ANAVI Macro Pad 2? Recently AE Chadwick used ANAVI Macro Pad 2 in his amazing home automation control center for his 1939 Minimalist Cottage.
AE Chadwick ran new wiring straight up into the ceiling and through one wall to connect to his home media server. Stream Deck is the primary interface and ANAVI Macro Pad 2 fits below it. Our open source hardware 2-key keyboard has a simple but important task in this complex setup to perform the feature ” “tap any key to wake the computer.”
AE Chadwick also designed a panel cut with CNC and 3D printed parts to hold the electronic gadgets. He was kind enough to share his experience in a Crowd Supply Field Report.
AE Chadwick, thank you for using ANAVI Macro Pad 2 and for sharing details about your project with us! It looks amazing!
The printed circuit board of ANAVI Info uHAT has a green solder mask and a gold surface finish. There are a few steps more to complete the manufacturing process. An EEPROM has to be flashed and soldered on each board. It will contain software description of the add-on board following Raspberry Pi Foundation’s HAT (Hardware Attached on Top) specifications. After that each board will go through a quality assurance, and finally each kit will be packaged in a recyclable cardboard box.
Low-volume manufacturing is not an easy task nowadays, especially during a global chip shortage. As usual we will keep you updated. Thank you again for supporting ANAVI Info uHAT!
OSHWA runs the certification program ensures that the definition of “open source hardware” used by a specific project matches the community’s definition of open source hardware. They provide a unique indentification (UID) for each version of the certified hardware based on the country code and a serial number. For example, the UID for ANAVI Info uHAT is BG000081. The prefix BG is the country code for Bulgaria, because the Info uHAT is made in my hometown of Plovdiv. The serial numbers show that now there are 81 open source hardware devices from Bulgaria.
Thanks to early backers ANAVI Info uHAT was successfully funded and hit its first stretch goal in a just a couple of days. So we’ll be adding some awesome KiCad and ANAVI Technology stickers. KiCad is the free and open source software we used to design this and other Anavi printed circuit boards.
As a small open source project, ANAVI Info uHAT relies on the community of passionate open source makers. We are near our second stretch goal of $1,000. If we hit it, we will make more video tutorials for all supported sensors.
There is still more than a month until the end of the crowdfunding campaign and we hope more people will jump in and order ANAVI Info uHAT!
By the way, “field report” is a program by Crowd Supply to highlight talented creators by publishing their projects, spreading the word among the community and also giving a $25 Crowd Supply credit. So if you are using any of our open source hardware products available at Crowd Supply don’t think twice and submit a Crowd Supply Field Report now 🙂
