Roll24:LIVE

We'll be running video for the Texas Robot Roundup in Austin in one week, and I've pulled out all the stops on this one, its now or never folks!

Things are a little hectic right now with the preparations, but I know we will be live all day Friday and Saturday, and hopefully I can bang  out a behind the scenes post soon after!

Wireless HD Video

I've been experimenting with a new toy recently, and I must say I'm very excited at the opportunities it opens up for my business. As you can probably guess from the title (and also the picture above of me streaming from a borrowed Panasonic Lumix to my MacBook) that what I have been experimenting with is a way to get HD from a floor camera back to my laptop wirelessly.

Enter the Teradek CUBE,

The cube 220 is a network video encoder, capable of generating a unicast video stream in many flavors (from 480i all the way through 1080p) and broadcasting it over wifi or ethernet. This is very cool tech, because it brings capabilities previously reserved for production companies with access to HD-SDI Transmitters costing tens of thousands of dollars and operating using large batteries and and large amounts of licensed bandwidth.

Today, small start-ups, such as our very own Roll 24 Productions, can broadcast full HD wirelessly from light weight, ENG cameras with only several thousand invested. Naturally its not that easy, it would be that easy if the tech would just stop changing for a darn minute, but I'll complain about that some other time.

At any rate, you've probably gathered  by now that I've gotten my hands on a Teradek Cube, and last week Nick and I took over a booth at the local Diner to try and get it up and running.

As you can see I'm very excited. This equipment represents  large leap forward for my business. All I can tell you right now is that this thing is tiny, light on weight and light on power. It also works, and now that I have it configured its simple to bump video from anything that has a HDMI output to my laptop. you can look forward to a full technical breakdown sometime in the future, once I get my hands on a camera other than Nick's Lumix to test with, and develop a battery solution that is held together with a woodworking clamp.

Arkansas

A week ago today I was in Bentonville Arkansas with the robotics team for the OMB off-season regional, it was a mixed bag, plenty of fun, very tiring, a little stress and a little suck. All and all an excellent road trip.

It was also the first gig that our fancy new camera snake saw any action on (here's Harry in the bleachers rocking our camera) and the guy performed like a champ! It wasn't the best production I've worked on, Blocked ports meant using uStream instead of WOWZA and volunteer camera men were somewhat shaky, but once we got rolling there was no stopping us, and we served 158 unique viewers.

We also had our fair share of trouble off the court, namely with a ATV we nicknamed "the squirter" because of its apparent distaste for engine coolant...

And of course! what road trip would be complete if someone didn't lock their keys in the car the morning we were set to leave?

But hey! Like I said, just the right balance for the perfect road trip. It was a blast and I can't wait to take the trip again (hopefully) next year!

Pneumatic Crimper

Here is the rough CAD of my pneumatic super tool, extremely rough, but it easily gets the concept across.  I've got many of the parts ordered and already on hand.

Next revision will need.
- Less metal, this one would be a little pricey in raw materials
- Adjustable height between bottom jaw and top jaw in open position
- A working CAD that is to scale and uses the proper parts
- A more compact frame (if possible)

 Here we see many of the power and control components, and I've received even more components in the mail since this was taken. I've also started on assembly of  the control box and decided that there is no room for the big red E-stop switch (Bummer, it wasn't really necessary, but it added a touch of professionalism.)

Blogging is hard. My thoughts never flow on the page quite the way they do in my head. The last couple weeks feel kinda like what I imagine being hit by six trains converging  in a star at the same time would. I'm hoping the summer will call down, its going to be difficult to keep this up.

Broadcast Camera Snake

And there we have it! the completed camera snake, ready for broadcast use. (well its not pretty yet, but once I have a shorter firewire cable it will be 100% done)

But I do have a finished 200ft cable that passes power and DV to and from between the camera and producers location. Overall I'm quite satisfied, and as long as the cable stands up to portable use I believe this will serve me quite well for run and gun broadcasts. The end goal of this project was for the cameraman to only have to drag one cable behind them and this has been accomplished to satisfaction.

Powerizing a hand tool

I've started a new internship this week where I have had the pleasure of crimping hundreds and hundreds of 1/4" QCs. It really is a pleasure, no sarcasm there, but the hand crimpers are killing me, and giving me blisters.


So enter the magical world of pneumatics! below is the bimba pneumatic cylinder I will be using to modify my lame hand crimpers into awesome power crimpers!

So far my design consists of a tower to support the crimpers (or any hand tool with a lever type action) by one handle and pivoting "palm" that attaches to the other and is powered by the cylinder to drive the tool shut.
The cylinder will be actuated by a three way valve, triggered by a foot pedal.

The end product will be a powerful accessory which will power most hand tools for icreased speed and lower strain.

Custom Cables

I've been making my own Audio and Video cables for as long as I can remember needing them, and tend to hold myself to fairly high standards (in other words, I can make a mean cable if I do say so myself.) So this summer I plan to supplement my income by manufacturing some custom cables for sale on eBay and my website. Of course I'll offer the good 'ole friends and family discount, so if anyone out there is in need of any length XLR, 1/4", IEC, Power or other cables hit me up. I'll update you guys with ore details once I get in the swing of it.

The camera snake is coming together quite nicely as-well. The voltage drop over 200ft of cable, while still significant, doesn't phase the camera in the slightest (it claims 50% battery.) One thing that is becoming apparent is that even with cable as flexible and durable as mine, 200ft 1/2" thick cable is a monster to deal with, and difficult to roll/unroll without kinking. I'll have to figure some sort of management solution out.

Once I get my hands on a male 5pin XLR and nice RJ-45s with boots this project will be complete!
