ANAVI Macro Pad 8 Manufacturing Progress

ANAVI Macro Pad 8 is an open source, programmable, eight-key keypad with backlighting, underlighting, and OLED screen. Following the successful crowdfunding campaign we manufactured the printed circuit boards in a small local factory in Plovdiv, Bulgaria, EU. We would like to explain in detail the whole manufacturing process.

The fabrication includes a procedure called panelization which groups together a number of PCBs on a larger board called a “panel”. In the case of ANAVI Macro Pad 8 the “panel” contains 3 boards. All of them are gold plated through electrolytic nickel-gold process. Gold is very expensive, especially at the moment, but it is still worth it. Gold-plated PCBs have excellent quality with high hardness, wear and oxidation resistance.

Sourcing parts in the COVID-19 time is a challenge but we work with trusted and reliable suppliers. We bought Microchip ATmega32U4 microcontrollers from Mouser. They arrived from the warehouse in Texas, USA. Each microcontroller is with TQFP-44 package that requires surface mount technology (SMT). The local factory has already assembled them alongside with all other SMT components.

The assembly of Gateron red mechanical switches and the red 3mm LEDs for all developer kits requires through-hole technology, a.k.a. manual soldering. This is a time consuming process. To simplify the work and to keep the mechanical switches on their places we created this plate that matches the size of the panels.

There are special holes on each mechanical switch for the 3mm LED. After soldering all of them, the leads of the LEDs have to be cut from the back side of the panel.

After all these steps, testing and packaging the developer kit will not require any soldering. However, people who enjoy soldering like me can order a maker kit and experiment with various mechanical switches and 3mm LEDs with different colors. Furthermore, the maker kit allows to perform a hot-swap upgrade as explained in the previous post.

After burning a the same bootloader as in Arduino Leonardo, flashing the open source QMK firmware and testing our mechanical keyboards are ready for packaging!

ANAVI Fume Extractor Parts Sourcing

The crowdfunding campaign for ANAVI Fume Extractor in Crowd Supply has been very successfully so far so we have already contacted suppliers and started sourcing various components. Most of the mechanical parts have already been delivered and we can have a closer look at them.

As some of you know, we will make and assemble the printed circuit boards in my beautify hometown of Plovdiv, Bulgaria. One of our goals is to support local manufacturing and if possible purchase parts from local factories and suppliers even when their prices are not the best. Of course, ANAVI Fume Extractor contains a lot of parts and some are so specific that nobody manufactures them locally. Because of this the project also relies on trusted suppliers from the US, the UK, Germany, Poland and China.

Parts for ANAVI Fume Extractor

Transparent Acrylic Enclosures

Each kit of ANAVI Fume Extractor contains 4 transparent acrylic enclosures. They have been designed with the free and open source tool OpenSCAD. The source and the schematics are available in GitHub. For the laser cutting I rely on a local Bulgarian company from Stara Zagora.

There are protective films on both sides of each acrylic enclosure. You must carefully remove them before assembly your do-it-yourself kit with ANAVI Fume Extractor.

Screws, Nuts and Stand-offs

20mm M4 stands-offs

ANAVI Fume Extractor contains various screws, nuts and washers for attaching the printed circuit board, the fan, the display and the sensor modules. The most difficult-to-source part is the 20mm M4 metal stand-off. Each kit contains 4 of them. We couldn’t find anyone in Bulgaria making stand-offs with the required size, so through a local supplier we imported the “abstandsbolzen” from Germany.

80mm Fan

80mm 5V DC fan

The key part of ANAVI Fume Extractor is the 80mm 5V/0.25A brushless DC fan. This type of a fan is primarily used in personal computers which makes it relatively quite and compact. Unfortunately, this is another part that nowadays nobody makes in Bulgaria so we are importing it from China.


All kits will come in an eco friendly recyclable cardboard box made in another Bulgarian town Lyaskovets. Although we do our best to reduce plastic packaging as much as I can, some small plastic bags made in Veliko Tarnovo, Bulgaria are still required to store the components in the kit. The stickers will be printed in Plovdiv.

The next step is the manufacturing of the printed circuit boards. Numerous components from various suppliers all around the world have to be assembled on the PCB. We will make it in a small local factory in my hometown of Plovdiv, Bulgaria. The manufacturing is scheduled to start right after the end of the campaign when we know the exact quantities.

Thank you for supporting entirely open source projects like ANAVI Fume Extractor!

Improving Industrial Manufacturing with ANAVI Light Controller

ANAVI Light Controller is an open source WiFi development board for controlling 12V low-cost analog RGB LED strip. Although it has been designed primary for home automation, recently ANAVI Light Controller was integrated in an industrial environment. is an innovative French start-up company reinventing the shipping. The company specializes in “first mile” logistics and provides services to e-merchants. Their warehouses in Paris, Marseille, Bordeaux and Lyon package and ship e-commerce orders. can be integrated with all leading e-commerce platforms, including the popular open source solutions PrestaShop, Magento and WooCommerce.

ANAVI Light Controller Andon Manufacturing
Wing’s warehouse using Andon manufacturing system implemented with ANAVI Light Controller and 12V RGB LED strips.

Running around the clock such an innovative logistics business requires excellent organization. To ensure high efficiency of the working process Paul Cancouet, project manager at Wing, implemented the Japanese manufacturing system Andon using ANAVI Light Controller.

Andon is a manufacturing term to alert about a problem in real-time. Pioneered by Toyota after World War II, Andon provides the ability to detect problems affecting manufacturing in real-time and fix them as soon as possible.

Paul and his team at Wing constructed a light indication on each desk at their warehouses, using ANAVI Light Controller, 12V RGB LED strip, appropriate 12V power supply, outdoor wall light, PVC tube and a 3D-printed socket. All Andon light indicators are communicating over the machine-to-machine protocol MQTT. The software on the server is written in JavaScript and Node.js. It spreads the information to Google spreadsheets, Slack channel and a HTML5 web interface that acts as a global monitoring dashboard.

The best part is that shared their server side source code in GitHub. ANAVI Light Controller is also entirely open source as the board has been certified by the Open Source Hardware Association and the default firmware is also available as an Arduino sketch at GitHub. Thanks to open source other factories can easily adopt the same solution and significantly improve the efficiency of their manufacturing process.

Paul Cancouet shared more details as a Crowd Supply field report. His industrial automation has been also covered by

ANAVI Light Controller is available at our distributors around the world: Crowd Supply, and Pi Supply.
