ANAVI Macro Pad 8 Developer Kit Assembly Guide

Please have a look at the video and follow the steps below to assemble ANAVI Macro Pad 8 Developer kit. Although you can do it with your bare hands, simple tools like a screwdriver, tweezers and a keycap puller might be useful.

ANAVI Macro Pad 8 developer kit comes with 8 Gateron mechanical switches and red leds. If you prefer another type of switches or color of the LEDs, please have a look at the Maker kit which requires soldering but allows to use different Cherry MX compatible switches or even make a hot-swap upgrade.

Step 1: Stickers

The first step optional. Each kit includes a set stickers. Feel free to add them to the translucent keycaps included in ANAVI Macro Pad 8 developer kit. You can do it with your bare hand or eventually with the help of tweezers.

You can place a sticker on the top or on the side of the keycap. If you like retro electronics you may find some similarities in this approach to the famous keyboard of the best selling personal computer of the 20th century Commodore 64.

ANAVI Macro Pad 8 is powered by the popular open source firmware QMK which allows you to create various layouts. You can make a keymap with 2 or more layouts. A sticker on the side of the keycap might be useful as a visual aid to indicate the additional function of the key.

Step 2: Keycaps

Place all keycaps on 8 mechanical switches of ANAVI Macro Pad 8. You can easily do this with your bare hands. It takes just a few seconds.

As you can see in the video a keycap puller might be useful if you make a mistake and want to pull off a keycap and place it on another location.

Step 3: Peel Off Protective Films from the Acrylic Enclosure

Peel off the protective films from both sides of the two laser cut transparent acrylic parts. The removal of the protective films is quite annoying but once you get rid of them, the acrylic enclosure will be crystal clear and fully transparent.

Step 4: Assemble the Acrylic Enclosure

Assemble the acrylic enclosures. In the cardboard box you also will find M3 black plastic screws, nuts and standoffs. Although you can assemble them with your bare hands a screw driver might be handy.

First place 4 of stand-offs with screws to the bottom acrylic part. After that place ANAVI Macro Pad 8 on top of them. The printed circuit board has 4 mounting holes for this purpose.

Add the rest of stand-offs on top of ANAVI Macro Pad 8 to secure the printed circuit board to the bottom part as shown in the video. Place the top acrylic part and fasten it with the 4 M3 nuts. Finally add the silicon protective pads on the screws on the bottom.

Step 5: Mini OLED Display

Step number 5 is optional. The default open source QMK firmware for ANAVI Macro Pad 8 support mini OLED display connected over the communication bus I2C.

By default mini display in yellow-blue 0.96″ I2C OLED. It comes with 4 jumper wires which might be useful for debugging purposes or if you plan to make a custom 3D printed case. However for the default acrylic enclosure the wires are not needed.

Peel off the protected film and place the mini OLED display as shown in the video to ANAVI Macro Pad 8. Pay attention to the labels that indicated the pin connectors of the display. They must match the labels on the keyboard.

Step 6: Turn On ANAVI Macro Pad 8

Gently plug a USB to microUSB cable to connect ANAVI Macro Pad 8 to a personal computer. Please be careful with the microUSB connector because a harsh bending of the USB cable may damage the microUSB connector.

Thanks to the QMK firmware ANAVI Macro Pad 8 will be detected as human interface device and should work out of the box. Furthermore with QMK you have the freedom to fully customize each key.

Please note that a USB to microUSB cable is not included in any of the kits. Reuse a cable from an old electronic device or purchase a cable according to your taste. Make sure that the cable supports both power and data transfer over USB.

Thank you for supporting and using our open source kits. Stay tuned for more updates, including details for soldering ANAVI Macro Pad 8 Maker kit.

ANAVI Gas Detector Assembly Guide

ANAVI Gas Detector is an ESP8266-powered, open source, Wi-Fi development board for monitoring air quality and detecting dangerous gases. After a very successful crowdfunding campaign at Crowd Supply we are manufacturing a batch of units in Plovdiv, Bulgaria. All kits of ANAVI Gas Detector also include MQ-135 sensor module, USB to UART debug cable, an acrylic stand and a mini OLED I2C display. In this article you will learn how to get started and assemble all parts in about 10 minutes.

The printed circuit board of ANAVI Gas Detector has the same dimensions as the one for my other open source product ANAVI Thermometer so actually both use the same laser cut acrylic stand. Both ANAVI Gas Detector and ANAVI Thermometer have been designed using the open source software KiCAD. The open source software OpenSCAD was used to design the case.

ANAVI Gas Detector Developer Kit

In this article you will learn the exact steps how to assembly ANAVI Gas Detector Starter Kit. The procedure is the pretty much the same for Advanced and Developer kits, however they including additional I2C sensor modules. Appropriate nuts, screws and washers are included in all kits.

Getting started with ANAVI Gas Detector Starter Kit

Step 1

Peel off the protective film from the acrylic stand. Also remove the protective film from the display.

Step 2

Mounting the mini OLED display to the acrylic stand

Using a screwdriver, gently attach the mini OLED display to the acrylic stand with the M2 screws and nuts as shown on the photo. The mini OLED display is fragile so please be very careful. Do NOT fasten it too tight because the torque may break it.

Step 3

Add four M2.5 screws and nuts to the case of the acrylic stand. In the next step we will put ANAVI Gas Detector on top of the nuts.

Step 4

Add ANAVI Gas Detector on top of the nuts and fasten it with the additional M2.5 nuts. At the end you will have a spare M2.5 screw and nut to optionally attach an additional sensor to the acrylic enclosure.

Step 5

Connect the mini I2c OLED display to the dedicated slot for it on ANAVI Gas Detector

Gently connect the mini OLED display to the dedicated slot using the male to female jumper wires. The colors of the wires do not matter. Just have a look at the labels on the top of the OLED display and connect each of the four pins to a pin with the same label on the dedicated slot for the display on ANAVI Gas Detector.

Add the MQ-135 sensor module for monitoring air quality

Plug the MQ-135 sensor module in slot labeled as MQ. Owners of Advanced or Developer kit should also plug the additional I2C sensor modules.

Finally, you are ready to turn on and enjoy ANAVI Gas Detector!

On first boot you need to calibrate MQ-135 and configure and connect ANAVI Gas Detector to your WiFi network.

The so called “burn-in” procedure for initial calibration of MQ-135 is important to be done on first boot. Despite its fancy name it is actually quite easy. Just place ANAVI Gas Detector with MQ-135 sensor module in a room with clean air and leave it running for at least 24 hours. This has to be done only once when MQ-135 sensor module is used for the first time. After doing this procedure, on every next boot ANAVI Gas Detector and MQ-135 will do a quick calibration in couple of minutes and start working properly.

We have also published this tutorial as an update at Crowd Supply to notify all backers of ANAVI Gas Detector. The whole user’s manual for ANAVI Gas Detector is available at GitHub. This is an entirely open source project so as usual ideas for improvements and bug fixes are always welcome!
