Cheap travel small screening projector

Published Date 4/25/16 8:52 AM

LED bulbs, cheap lithium battery’s and high power USB charging have changed what a projector is. Its now easily possible to have a full cinematic experience in your pocket and run it for hours on very cheap USB battery’s. The days of expensive, power hungry and fragile projectors are over for all but the most demanding permanent set-ups. The are hundreds of these “micro” projectors available, they vary in quality a lot, here is a review of a good one.

If your looking for a very cheap travel/small screening projector I can recommend this one

ECsee-ES130-Mini-DLP-Projector

Tiny, relatively well made, lots of ports and did I say very cheap.

LED bulb so robust long life and low power.

Plays videos from HDMI, USB thumb drive, micro SD card in many formats (it will not play surround sound audio files). As with many embedded playback devices it can get the aspect ratio wrong this is a normal problem. Will work fine by HDMI with image and sound from a laptop etc.

Used it at a recent all night illegal rave party under a railway bridge to provide background images, plunged into a small USB battery (5000mah) it easily lasted the night on loop.

Fits in your pocket and has a built in battery which last 1-2 hours, charges/runs off standard USB up to 2amps.

Its no were near its rated 800 lumen, more like 50-100 which is normal for a projector this size. You would have to pay something like £500 for a 500 lumen LED projector. Its brighter and the sound is louder if you plug it into a 2amp USB battery/power supply rather than run it off its internal battery.

Sound might be an issue when running on mains power due to hum.

In darkness it creates a large bright (somewhat over saturated) image, like all micro projectors it will struggle to overcome ambient light.

Open Media Network

The project

The Open Media Network is a project to play a small role in revitalising the open web. It uses the tried and tested technology of RSS, taking it out of a basic personalised mash-up of feeds into an open metadata social network. Its initial focus will be around alternative media, enabling projects to grow and cross-fertilise independently of the social media corporate giants.

Rationale

The #dotcom silos are completely dominant in terms of people’s identity, for publishing and for networking etc. At social events you once gave your phone number, then your email address, and now you friend on facebook.

By contrast, the open web has plateaued or is already in decline, depending on your point of view. To fix the issues of why the open web is failing we first need to look at why it succeeded:

The internet/web was a KISS trust-based network that took over the world we have been living in for the last 30 years, and it was no accident that identity checking and security were missing from the original internet/web.

To reboot the open web will take many overlapping streams of open projects. Here we are proposing a KISS project to that end.

Let’s look at a small, once healthy stream. Alt/grassroots media used to play a large role in the world. Now all that remains is a few sprigs of green in a polluted/dry river bed. In its heyday the global #indymedia (link broken) network rivalled the BBC and CNN in its scope and coverage on the big days of action and international summits. Now all that is left are some strongly branded small projects (http://novaramedia.com), that grew from #dotcom social media and are only networked within them, and a handful of big legacy projects (http://www.democracynow.org).

The problem we face is a pre-web problem, that of silos. That is each project is a small pool in a empty/dry river and there are very few links or shared data from one to the other (link to 3 projects). The currency of the web is the “valid link”to build networks. Alt-media’s growth is severely limited by this lack.

Open Media Network

The OMN is one project to fix this problem.

It is a project of the 4 opens. It is a human-based project at its core, as opposed to an algorithmic project.

Quite simply we want alt-media sites to link to each other and share content, to become a healthy network rather than isolated drying-out silos. 

The outcomes needed for it to work are easy to achieve, and they have a large possibility to grow/empower projects as a network.

The project uses RSS as a data object exchange format, using a tagging folksonomy as a way of shifting the data flow between federated sites. It uses both native code plug-ins and javascript to “embed” links to this tagged data flow in open web sites and blogs (working example visionontv side bar on http://newint.org)

RSS aggregating news portals are not new, which is a major part of their strength for the realizing of the Open Medium Network. Taking this tried and tested tech into an open metadata social network is new. Another thing which will be new to some of the media side of the project is the 4 opens.

Each participant in the OMN will embed at least one news river in their sidebar. 

The plan is to build synching aggregating portals / hubs (based on existing CMSs) that feed those sidebar rivers.

Human networking based on trust is key.

Aggregators choose to link RSS feeds into their hubs.
Users choose the tags for the link streams from the hubs into their side bars. 
To facilitate trust, basic security is built in.

  • flows can be on auto or moderation
  • there would be a feed-based roll-back for when spam gets through the trust network.

User embeds, either native or JS, are boolean tag based and have metadata editing rights based on trust (hosting hub gives them this), with 3 levels: auto/moderation/rollback.

NOTES for Developers:

This project uses technology to build a human network. There’s a sense in which the simplicity is as important as the code. The project can grow to work in many different ways but the base has to be KISS. 

NOTES for journalists and media makers:

You retain complete control of what appears on your site. As the trust network builds, it will become higher quality and faster to administer.

Outcomes

From simple springs big rivers grow to feed the sea.

In my 30-year experience, I have seen too many alt-media projects grow, flower and fade away, without aggregating or archiving themselves into a state of permanence.

This project can play a crucial role in solving this, as hubs will not only be able to moderate the flows of news, they could achieve it, with no extra work, in a massively redundant distributed way. 

The same basic project and tech will work fine for the blog-rolls of sites, creating more “static” dynamic linked side bars. This will reboot the idea of “webrings”. 

It can also form the basis of identity. People are just a tagged data object that can be sorted into “flows”. This opens up social networking to creative thinking. 

Sites link to each other both though trust, the human side, and through links, the machine side. Both are a good opportunity for the open web to compete with the closed silos.

The networks of hub sites become portals in their own right, driving traffic to the root news orgs/blogs that feed them.

300 words

The Open Media Network is a KISS hybrid client server/peer2peer project to play a small role in revitalising the open web. It uses the tried and tested technology of RSS. Its initial focus will be around alternative media, enabling projects to grow and cross-fertilise alongside the social media corporate giants.

For the full background to the project see this http://hamishcampbell.com/en/home/-/blogs/open-media-netwo-1?

  • Stage one (6-12 months) basic linking and embedding programming, basic beta roll-out – the outlandish funding.

  • Stage two (6-12 months) is synchronising and meta-data editing, then expanding roll-out.

When we have basic working code, set up a number of exemplar hubs to beta test the project in the real world and push out embeds to existing real world alt-media sites.

This project is largely social technology. The tech part is configuration and repurposing existing CMS’s and their plug-in architectures.

Pre-programming – there is a need to look at the existing code/plug-in base and spec out a number of roots to working aggregating CMS to seed development.

List the parts that need scripting/programming/configuring.

Work out the basic meta-data format (RSS/atom) 

These no exclusivly act as “seeds” for the aggregating hubs. They already have some of the basic functionality needed. Take this list to open source programming projects such as LINK etc.

As an open project built peer2peer, the core is to get a lot of people at different levels of expertise working on each bit and run them all in parallel. There is no right answer and no signal point of use/failure.

 visionOntv project can offer to match the funding coming from outlandish.

I take this comment from a famous programmer as a complement “feels dated in the language and tech” that’s the point 😉

————————–

Briefly describe what support in addition to funding you would require to make your project a reality. This could include people with other skills, or office or event space.

The funding is nice to keep focus, but the core help is the links and knowledge network that outlandish provides. The content and media side we can handel. The running of aggregation we have been doing for over 20 years, over many generations of failing alt-tech. At the moment we only have youtube play lists and embeds, this is a crap situation, not to say embarrassing state of alt-media.
