my new vertizontal cart

Hey all, just thought I would post some making-of and in-action photos of my new cart. I built it just prior to a film I'm currently on and it has been performing very well. I really wanted an encapsulated rack based design, but also have something that is portable enough to break off into a smaller "brain" for insert car shots, etc. I also wanted to make the rack unit as ergonomic and space efficient as possible. I'm one of these fellows who likes to stand while he works as well.

The first photo shows the panels cut out and being held together for final measuring purposes. All the equipment fits in with not much room to spare so I really had to make sure there was clearance for connectors, cables, etc.

The next four photos show some tiny drawer slides I found to mount my keyboard on. The angled shelf holds my 788T and the keyboard hides underneath it until I need it.

I can't say enough about how much I like the computer in the next few pics. A friend and I built this hackintosh and it has been really great (despite a few hackintoshy bugs that are getting ironed out). The gist of the computer is that it's all solid state, has panel mounted XLR ins and outs for audio via an internal USB audio interface, and a very efficient 12V regulated power supply with a panel mounted XLR4 input. I wanted it to run Wave Agent, LecNet, and something for playback. Having two monitors really makes a huge difference for certain programs as you can see in the photos, and also puts a lot of display in 3 rack spaces. The computer itself is mounted on the back of the cart on it's side behind the two 7" monitors.

Next! Lights. I made a wooden enclosure wrapped in diffusion and placed an 12V LED light strip inside for the front of the cart. For the back I placed the same type of light strip naked wired to a rocker switch.

Other things... I mounted a female XLR input on the front of the cart that I plug my slate mic into. Makes a nice sturdy connection point that terminates to a TA3F for the channel 8 input on my 788T. I have I/O panels on the lower back of the rack for all my other connections.

The last few photos shows the cart in real life. I call it a "vertizontal" cart for because my gear is arranged in a vertical style, but mounted on a horizontal cart. My cart base is a Rubbermaid with 8" pnuematic tires replacing the casters and all the fixings for boom poles, cable hooks, antenna mast, etc. I am planning on building a steel skeleton inside the cart for more rigidity. The rack on the bottom has drawers for gear and lightweight Crown XTi series power amp. You can see how the rack comes off easily (two thumbscrews on each side into aluminum brackets) and fits, for instance, into a bus for a driving scene or onto an insert car.

Thanks for looking!

Very unique approach --- I like it. "Vertizontal" description is clever but I think it is basically an upright horizontal design that just happens to be supported by a horizontal cart (platform). At some point in the future I'll bet you ditch the Ruubermaid and go with a wheeled platform base that has essentially the same footprint (square, upright) as the cart racks. Your design is one of the few that uses a triangular or trapezoidal (something other than square or rectangular) main car space. This helps provide working access to the gear without having to have too many sliding shelves or having to reach into the cart. Several of the RastOrder carts do it this way and I think it makes a lot of sense. Now, I am inspired to build yet another cart that is truly modular with an upper part that can be easily separated and used in a more mobile fashion. As you know, my present cart was designed to separate into two parts but the upper part (with most all the gear) just got too big and too heavy to lift off the lower part so I never separate the parts.

Also, curious about the Hackintosh route you took with the computer. It looks like you are running all Mac software so why not go with a Mac Mini? I guess Lec-Net is Windows only but that can be run in Mac OS with emulation (or dual boot if you want). Maybe starting with the hardware you used gave you as lot more flexibility with the I/O, stuff you definitely would not have with a Mac (we all know how Apple doesn't want you to do any fiddling under the hood).

Jeff,

I think this explains Alex's choice for the Hackintosh. Sounds brilliant to me...

"The gist of the computer is that it's all solid state, has panel mounted XLR ins and outs for audio via an internal USB audio interface, and a very efficient 12V regulated power supply with a panel mounted XLR4 input. I wanted it to run Wave Agent, LecNet, and something for playback."

I also think Alex will ditch the Rubbermaid, and end up with something more along the lines of the top section footprint.

And yes, Fabian I was pretty sure it's a K, because it reminds me of my K75s dashboard.

Regards,

Jim Rillie

Thanks guys.

Spencer, yes there was definitely inspiration from an arcade cabinet!. I stumbled upon this http://www.instructables.com/id/How-to-build-a-Nintendo-arcade/ one day and instantly imagined it on a cart. I am thinking about having some classic arcade vinyl graphics printed that I can stick on the side...

I may ditch the Rubbermaid one day, but for now it really fits my needs. It's just big enough without feeling like a larger Magliner cart. I have all my gear arranged just like I like it with a small space on the side (the rest of the cart top) for prepping wires, additional gear, etc. Who knows though? I seem to change my setup frequently so I may not be so in love with this setup in the near future.

The Hackintosh certainly isn't as pretty or small as a Mac Mini, but it is a purpose-built computer whereas the Mini isn't. I also forget to mention that it has FW 400 and 800 ports, and eight USB ports for max connectivity. This might sound like overkill, but I will never need to rely on a USB hub or adapter cables for different FW connections now. And having the more rugged, locking connections for audio and power built into the box make it feel more reliable to me.

Unfortunatly I am not a bike guy, so I can't say which model it is. I built the cart in a friend's basement who is a bike nut. I sent him a message asking which bike that is. I'll let y'all know.

Alex,

With all that computing power onboard, what are you using your laptop for? And does anyone ever accidentally deposit a quarter into your cart?

Looks great. Really cool. I remember you showing me the designs. Glad it has worked out so well for you.

Never did much cart work ; what's the main use of speakers on the cart ( I notice your Speakeasy unit) ? I guess, keeping the boom on between takes and monitoring what's happening on the set ?

I feel a little dumb asking something that's surely obvious since a lot of carts I see have some kind of speakers on them... :-S

Hi Pierre, I find myself using the speaker quite often actually. There are the times you mention when I am between takes and don't want to wear my cans (or in-ears in my case). Also, it comes in very handy for playing back takes for a group of people, auditioning playback tracks for talent/clients back at the cart, and playing tunes while wrapping at the end of the day!
