Introduction: DeskPomo----pomodoro Timer to Improve Your Working Productivity.

About: About two years ago when I was doing my industrial design project I wanna find out a hardware solution to let me have a FPV(first person view) experience remotely. My use case at that time was to know how my d…

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The technique uses a timer to break down work into intervals traditionally 25 minutes in length, separated by short breaks. These intervals are known as "pomodori", the plural of the Italian word pomodoro for "tomato". The method is based on the idea that frequent breaks can improve mental agility. ----copy from wikipedia. \

As a maker, I'm really look high to the working productivity. Since that, I've been trying to use some time management app on my iphone. But after a period using I find out that the phone was just maked me distract all the time. I have been spent a large amount of time when facebook or twitter notification comes up which I don't even notice. Finally, I‘ve decided to pick up my seeeduino and work out these little cute gadget which keep me focus on work.

Step 1: Hardware Assembly

Material required:

Mechanical bit:

1. Lasercut plywoood. (source file provided)

2. 8x3mm screws and nuts X4.

3. 25x3mm spacer screws X8.

4. 6X2mm plastic rivet X5.

5. 8x3mm plastic rivet X3.

Electronic bit:

1.Seeeduino V4 or any arduino board X1.

2.Grove-based shield X1.

3.Ws2812 LED breakout board X1.

4.Grove-Touch sensor X1.

5.Grove-4digit bit X1.

6.Grove-servo motor X1.

7.Grove - Universal 4 Pin Buckled 5cm Cable.

Tools required:

1. Laser cut machine.

2. Soldering tool.

3. Hot glue gun.

4. Screw Driver

Step 2: Electronic Bits Assembly

As the photo shows, using plastic rivets to mount the board and sensor on the laser cut plywood.


Soldering is always the most fun part. In this cast, because of the WS2812 break out is very tiny, so

the whole process gonna be a little bit tricky. First, use some hot glue to set the led pad on position. Second, carefully solder and wire up all 5 leds. Within this phase, you should break up one of the Grove connect wire and solder on led pad in the same way as the picture in order to make sure it will easily connect to the basic shield. finally, using hot glue to cover and tide up all the leds.

Step 4: Final Assembly

The whole construction which is not hard, just do it as the the picture shows. Only one thing should becareful is attaching the wire. Do it as the instruction below!!!!!

Grove-4 digit --------------- D2.

Grove touch sensor--------D4.

Grove servo-----------------D6.

Neopixel LED Breakout----D8.

Step 5: Coding

Once you power the deskPomo. It will automatically start counting and once the counting finished our deskPomo would shows the sum up pomos for you. In this stage, if you still working on your current project, tap the touch sensor to move on. If you have already done your project, give a long press(>=2s) to send the pomos to Total channel. You get it? Enjoy.

Step 6: Function Flowchart

As the flowchart shows, the whole process will be separate into 4 stages.

Step 7: Download the Lasercut File

Have fun and tell me how much pomos you've collected!!!
