Here’s a nice trick I learned about when I was building an escape room. When using an Arduino to control LED tape, instead of building your own LED driver with MOSFETs, cheap LED amplifiers can be used. Here I stuck one to the back of an Arduino Nano for a super-compact driver.
Right now I’m working on a project that plays back 32 tracks of audio over 32 discrete speakers. Each track needs a different amount of delay and EQ, since the speakers are spread across a large area with lots of audio reflections. There’s no way to EQ or delay on the multitrack audio server we’re using, so we need something else. Continue reading
On a recent gig I was introduced to the Riedel Riface. It’s a custom rack-mount chassis for two Motorola GM360 radios, so they can interface with an audio console, intercom system, or even themselves to use as a repeater.
One of the other guys in the company figured he could build one for cheaper than the commercial version. It uses two Icom IC-F6011 base units. Getting audio out of the Icoms is easy, there’s a 3.5mm stereo jack on the back.
Getting audio into the unit is more of challenge.
ENG lenses are great. They have long zoom ranges, zoom motors, comfortable hand grips, and are more ergonomically friendly than other zoom lenses (especially still lenses.) So it’s no wonder people want to put this glass on their digital cinema cameras.
The job: Build a two-part light-box wall 3 feet high by 15 feet long and 3 ft by 21 ft. The box’s panels must be interchangeable to accommodate different designs. The backlighting for the wall must be pixel-controllable for animated wipes and patterns.
This light box was to be installed in a television studio to cover up an existing ugly concrete wall. Designs were done in SketchUp during the planning process. Continue reading
Making your own XLR cables is a great way to ensure you’re getting a quality product built to your exact specifications. One you get good at making standard cables, making custom adapter cables is a piece of cake. I’ll show you how to make a standard XLR cable below. Continue reading
Inspired by a new soldering iron and a surplus of orange LEDs, I decided that I wanted to build an LED flasher circuit. We’ve all seen two LEDs flash in an alternating pattern, but what about something a little more interesting? Oddly enough I found my answer on YouTube. Continue reading
I have always been a fan of audio. I like hearing stuff. I hate when films (student or otherwise) have bad audio. Using the on-camera mic is right up there with not using a tripod in my pet peeves of films. I have a lot of audio equipment, more than most student film makers probably. Here’s a list of what I have: Continue reading
Taking things apart is one of my hobbies. Doesn’t matter if they’re broken or not, I’ll take it apart to see how it works. In case it does break, I’ll know that I can fix it. I bought two T4900 radios from eBay. They are awesome little radios. The audio quality is phenominal, especially compared to the T6200’s, which is much worse, despite being newer. Anyway, I finally figured out how to take them apart: Continue reading
In my ongoing hunt for good audio, I decided it was time to get a real audio interface. I had been jury-rigging my mixer with more adapters than most people own in order to get the sound into my laptop. I finally gave up and just did a search on eBay for “audio interface.” I picked the highest price I was willing to spend, and watched every single one below that price. With the help of JBidWatcher (an awesome piece of software) I was able to snag a Tascam US-122L for half-price.
I was excited when it arrived, all shiny and visibly used. But as long as everything works, I don’t care about a few scratches. I installed the software, fired up Audacity, plugged in a mic, and… Nothing. Audacity gave me an error. I thought I had researched this one and confirmed it was compatible with Audacity. I tried Garage Band. It worked perfectly. It was obviously something wrong with Audacity. But I had read about people using it with no problems. On a whim, I decided to install the Snow Leopard driver (I only have Leopard.) Voila! It worked.
So now I have a fully functioning USB audio interface. I like it. It has rudimentary level meters (a green light that turns orange, then red when the level gets too high.) It accepts line and mic inputs, and it provides phantom power. The US-122L plus Audacity equals a pretty legit recording studio. As long as you only need to record two tracks at once. For $65, that’s fine by me.
