And that’s a wrap.

A huge thank-you to everyone who made OTA16 a fantastic event – the 8th and last, of the Over the Air series.


The workshop programme was full of some truly amazing talks, the hall was filled with the buzzing of collaborations and learning, the crypt was a bean-bag filled cozy hacking zone, and the hack entries were awesome! With huge props to the Sponsors who made it all possible.

And at the heart of the event is of course the Over the Air community – that’s you!

Here are the first of the photos in the OTA16 Album in our Flickr Group – do add your own as well.

Interviews by Christian Payne (Documentally) on Twitter & Audioboom

The lovely team at Nexmo, our cornerstone Sponsor this year, invited Christian to interview a number of participants, some of which you can find here on Audioboom, and others you can find on Twitter – such as his interviews with Rev. Graham Hunter, Paul Johnston, Dom Hodgson, Andy Piper (two times) , CoderDojo attendee Simone Luis,  Tom Durrant, Matthew Rollins, Tristan Roddis (and Paul again), Sam Machin, Alex Bucknall, James Smith, Hadley Beeman,

Here’s a taste of the conversations that took place – too much for one blog post naturally, so do check out the full storify.

Support our amazing Venue by making a donation

We’ve asked Rev. Graham to set up a dedicated donation tool for the attendees of Over the Air 2016, so that we can offer some additional financial support for this amazing building, and the services it offers both the local community and the technology community.

Our generous sponsors have made this year’s OTA possible, but only at a reduced rate for the venue, and they really need the financial help themselves. Please help us make up that shortfall by making a donation. 

This fund is for guests at Over the Air 2016 to make donations towards the cost of the event. Sponsorship has not covered the whole cost, and the church has been flexible with it’s hire fee – but is now facing a shortfall. Please give generously to cover the church’s costs, and support its wider work in the Hoxton neighbourhood. Ps. If you use GoCardless to donate, the fees are lower than Stripe – so the church ends up with more money!” – Graham Hunter

Running OTA16 on an ‘austerity’ budget

2016 has certainly been an interesting year – possibly the most glued-to-the-news that we’ve ever been, and huge divisions exposed across western society.  An excellent time for us to come together in a celebration of what we can achieve when we share knowledge and collaborate on fresh ideas for a shared future.

But it has been a year of changes in the mobile industry as well, with many reorganisations taking place, and tactical changes to how companies approach developer relations and outreach. Many of our supporters over 9 years of Over the Air have been faced with budget cuts, stretched teams, and major layoffs… necessitating our move to a new date from the original plans for September.

Winning a few more months to plan the event has unfortunately not had much of an impact on the financial picture – even with the help of all of you lovely people who have chipped in a fiver. We now find ourselves running an ‘austerity’ budget, and are having to get mighty creative on where we can save a quid or two.

Can you organisation support us?

At the moment we are particularly looking for two Lunch Sponsors – without whom we’re going to have to ask everyone to brown-bag it for the two days. We don’t have enough money for a second Marquee, and we also don’t have money for Bean Bags.

Here’s what the budget looks like – we are currently £5k short of the ULTRA minimum budget.

We’re getting Arty at OTA16

21617447969_65c88afdb7_zOver the Air has always been able celebrating programming & development as a creative discipline, but this year we’ll be inviting you to explore your artistic side as well.

We’re pleased to welcome Hercules Fisherman to the team as curator of the Art Space this year! You may know him as Herx, and a fixture of the Hardware Hacking and Start-up scene, but Hercules is an artist as well, and he’ll be bringing a whole new realm of creative expression to the event this year.

If you’d like to contribute interesting materials for an artistic hack this year, do send him a note on Twitter! @Herx


NEW DATES!!! November 25th & 26th, 2016

Many of you who have been following us on @overtheair and #ota16 have been asking us about when registration would open this year, and indeed we’ve been hesitating to go live because we saw that this moment was coming… we need to move the dates for this year’s Over the Air to November.

It’s been a mighty ‘newsworthy’ few months with lots of changes going on in the industry, and we simply haven’t had enough sponsorship commitment at this point to put on a good event in 6 weeks time. But now that we’ve bitten the bullet, we’re raring to go again.

For starters: Registration is now Open!

Although tickets are free as always, for the first time we are inviting those who are able to make a donation towards the costs of the event. If you can make a contribution of any value, it will be greatly appreciated.

And while you’re at it, why don’t you also submit a proposal for a workshop? As sessions become finalised we’ll be posting them along with speaker details on Lanyrd.

We hope to see you in November.




On Diversity at OTA

As more and more companies become aware of the issues of diversity of representation within the technology industry, we occasionally get asked where we stand on this issue as Event organisers.

Well, we care about it very much, and make a concerted effort each year to reach out to communities of people who are typically under-represented at technology events, especially Hack Days. It’s one of the reasons that we have always worked hard to keep the event free to attend – we know that financial barriers also play a role in this.

We are quite proud of our consistent gender balance at our events, which has ranged from 30% to 50% female amongst both participants and speakers (check out the 2015 speakers list on Lanyrd). Exactly half of our Keynote speakers over the years have been female as well.

To ensure that our event remains a welcoming and positive place for all, we explicitly support the Hack Code of Conduct and the Diversity Charter.

But we are not resting on our laurels, and care about other areas of diversity as well. Technology events are rightly challenged on their record in welcoming and giving the stage to people of colour, people of different faiths, people with physical mobility challenges, and people in the LGBT community.

Help us spread the word!

When community groups form along these lines it is quite simple to reach out with an invitation – but we know that we could be doing better at spreading the message more widely. As we prepare to open up this year’s registration, please share your suggestions with us about how we can reach new people who might not otherwise know about Over the Air.

Recommend a Speaker

Know somebody who is involved in an innovative / inspiring line of work and a great speaker, who isn’t getting the stage time they deserve? Then encourage them to submit a workshop proposal or Lightning Talk proposal (while getting them on our radar as well) – or better yet, recommend them to us as a potential Keynote speaker.

Younger participants also welcome

It’s worth mentioning that we make the event accessible to younger people as well, not only inviting students and recent graduates to join us as participants, but also offering ‘Coding for Kids’ workshops on the Saturday morning. Last year for example, Coder Dojo London ran a highly successful BBC Micro:bit workshop for kids on Saturday, which was the first public event of it’s kind, and Microsoft ran a BBC Micro:bit training session for parents, ‘Coding for Kids’ volunteers, and enthusiasts the day before. (N.B. that children under 18 must be accompanied by an adult at the event)

Sponsoring Diversity

We are still looking for Sponsors for this year’s event – if your company is passionate about supporting diversity in tech, then OTA16 is a great opportunity to keep those financial barriers down and add your voice to the welcome call. Specific opportunities include sponsoring this year’s Coder Dojo workshop, sponsoring the Lightning Talks that feature a diverse range of speakers, and sponsoring the venue, which is fully wheelchair accessible. Get in touch with margaret at overtheair dot org to find out more.
