7 November 2010 - 23:28£5 App #23 – “Things we built this summer”

Last Tuesday we had our 23rd £5 App event, given that it is only our second event this year we chose to let people “show and tell” about the things they built this summer. We had 9 speakers, I bought the beer, John baked the cakes.

Shardcore and the Englightenment Machine

Shardcore‘s Enlightenment Machine was installed at the WhiteNight festival a week back, here he explains what’s going on:

Jon and Digestly

Jon‘s Digestly lets you summarise tweets which can then be sent by email to e.g. your mum who wants to hear more about you:

Ian (me!) and the Social Microprinter

My Social Microprinter is a CBM 231 receipt printer + Arduino + WiShield + remote server, it prints tweets and useful info using a regular shop’s receipt printer via serial:

John’s Arduino-powered door-bell couples a regular remote-control doorbell with lego, wood and a big bell:

Seb built a Family Fortunes clone recently (we played it at BarCamp Brighton) using Flash, Nun-chucks and an iPad:

Emily and SocialTies on the iPhone

Emily is working on an iPhone app with me that we’ve named SocialTies, it helps you find your friends and ‘similar people’ when you’re at an event or conference. It was inspired by the fruitless hours I’ve spent at events wondering if I’ll ever find anyone I know…

Kyran and JavaScript Social Graph Visualisations

Kyran and I have been working on some social graph visualisations, Kyran’s interface lets you see where you sit in an event’s social network whilst reading real-time updates from attendees:

Mike and the Tardis Money Bank

Mike’s Tardis Money Bank was designed to help him and son keep tabs on pocket money. It has gone on to be used by many families since its launch:

Jay and Twitter Election Predictions

Jay’s real-time election results predictor read Twitter during the UK elections, the results were interestingly accurate:
