TeaBot V2

Tea timer/dipper to make sure your teabag only remains for the intended time in your cup.

It has the following features:

• adjustable time from 1 to 9 minutes
• start/stop button
• power switch
• powered via micro-USB cable
• one hand usage 😊

This is a completely new design, but with nearly identical electronics and programming from TeaBot V1. 

After using TeaBot V1 for about a year I finally wanted to get rid of some of its limitations:

• No one hand usage (which is annoying in an video conference). These are in detail:
  • Starting the timer (without the whole thing moving around)
  • Attaching the teabag
• Open electronic (on a breadboard) at the back (and sometimes ripped out cables)
• No stop function (e.g., if you started with the wrong time setting)

Used Tools:

• Design was done in Fusion 360. 
• Electric Layout was done in fritzing (and if a PCB is needed I tend to use their service as well).
• Programming was done in Ardunio IDE.

Used Parts:

• Arduino Nano V3
• 0,96 Zoll OLED 
• 9g Servo
• Switch
• Button
• Poti (I used the 10k Ohm, but 5k Ohm to 50k Ohm should be fine as well)
• Micro USB Plug

As you can see I typically get my parts from AZ-Delivery or Amazon.

Printing:

Base, Body and DisplayHolder can be printed without supports. The Arm requires supports. The assembly of the servo / arm unit is tricky and needs to be addressed in the next version…
