Interactive WeddingBots Built Into Nespresso Capsules

Today is a very special day for [Mandy and Sebastian], as they conclude the sacred solder joint of marriage. We send our sincerest congratulations and best wishes to the bridal couple, and can’t help but envy the guests of their ceremony, who received a very special wedding favor: A WeddingBot.

img_3337For their wedding party, [Mandy and Sebastian] created a little game on their own (translated). Each guest would receive a unique, little WeddingBot. Each of these is individually tailored for a certain guest and features a fitting look, a characteristic behavior and would play a special melody or jingle meaningful to this guest. However, the guests don’t get their WeddingBot, they get the WeddingBot of another guest – and the challenge to find this guest on the party. Guests would then exchange their WeddingBots, which also makes a great occasion to introduce themselves to each other. If the clues given by the WeddingBots themselves would not suffice to find the right owner, guest could place a WeddingBot on a clue station, which then would provide further hints by displaying images, texts or even riddles.

The design is based on the ATtiny45 microcontroller, with LEDs for the eyes, a light sensor, and a piezo disc for the sound as the main components. As an enclosure, they chose to repurpose empty Nespresso® capsules, which look nice and adds volume to the PCBs. The smiley face silk screen on the PCBs was then individualized with a black marker and packed in a beautiful hand-crafted box. The little fellows communicate with the Raspberry Pi based clue station by flashing their LEDs in a certain pattern. A light sensor hooked up to the Pi lets the station identify the bot and display the corresponding clue on a screen. Check out the video below to see how it works:

  1. I’m glad to see someone finding uses for those pods, my wife got us a machine and for all I love the coffee, I hate the waste. Ours is a machine that uses plastic pods, the only ‘hack’ I’ve found is to pierce the foil completely, tip out the coffee and collect it in a bag to throw on the garden.
