The hardware costs for our foosball table hack was about €150, consisting of the following factors:1 x Arduino Uno€301 x Arduino Wifi-Shield€802 x Infrared photo sensors€20bits and pieces€20--total€150The foosball table itself was already at our agency, as were the iPads or smartphones which are being used as displays.As all the programming and designing was done in-house, the labour costs were fairly reasonable as well:2 x Frontend Engineer for 2 weeks€250 p.d.€5,0001 x Designer for 1 week€200 p.d.€1,0001 x Project Manager for 3 weeks€250 p.d.€1,250--total €7,250After we finished the project many of our perfectly connected colleagues used their social media channels to promote the work, which was the only promotion.Since we obviously hit the mark the project received wide media attention, including many major German newspapers and all special interest magazines. Furthermore the word spread internationally, including Wired and Techcrunch – the leading online magazines for our target group. Then the bloggers picked up the story…So we generated a total media volume of over €200,000 by investing €150 plus some fun (which cost the company €7,250).
