Hang Prints with Magnets An inexpensive solution for displaying prints you want to change frequently
I spent a long time looking for a way to display my prints. This is my DIY solution that doesn’t damage walls, and lets you quickly change out your pictures.
Custom PWM Configuration for Arduino MKR WiFi 1010 (SAM based)
High-frequency PWM is necessary for some applications, like flicker free video lighting and 4-wire PWM fans. This guide covers the basics of configuring and using the built in PWM generator of the Atmel SAM D21 micro-controller that’s used in certain Arduino devices, like the MKR WIFI 1010.
Building a Hyperbolic Resolution Wedge in Illustrator
In another article I described and made available my camera acclimation target. In the process of building that I ended up having to sit down and build from scratch what I’ve frequently seen described as a hyperbolic resolution test wedge. If you’ve ever used an ISO 12233 resolution chart, or looked at the resolution charts […]
LED Panel Project – PWM Control Test 1
Over the past couple of weeks, I’ve been writing about my LED light project. This article is no different. There’s functionally two aspects of this project that I’m working on simultaneously. One is designing an actual LED Light panel, we the controller for one at least ,and the other is more investigative work on various […]
Dynamic Range and Lights
Today I want to talk briefly about dynamic range, but not that of a camera sensor. Instead I want to talk about the dynamic range of a light. As I mentioned in a previous blog post, I’m working on designing an LED Light Panel controller and part of designing such a thing is figuring out […]
Quality of Light Tests – DiY Light Panel
Quite a while back, before I learned the proper terminology, I wrote about the metameric failures here and here that occur when using non-tungsten light sources. These sources have become increasingly common and popular due to their low power consumption and low heat output, and solid state — LED — lighting forms the basis of […]
Powering Projectes – Batteries
I just finished soldering together my first test LED light panel, it’s only 492 lumens worth of LEDs, but it’s good enough to start testing a lot of the electronics. So things are slowly moving forward. Today though, I want to talk a bit about power, or rather batteries. I first started thinking about power back […]
DiY Clap Sticks
To quote Vincent Laforet, “50% of any great film is in the sound design, and the first step to great sound design is capturing great audio while on set.” How you get that audio is the big question. Clap sticks, with or without the addition of a slate, is one way of easily synchronizing sound […]
Basics of Building DIY with PVC
Learn some of the basics for working with PVC pipe to make your own light shaping tools like scrims and soft-boxes.
Design and build yourself a scrim. Why a scrim? Put simply, it’s a highly versatile light modifier that costs pennies to make.
