Take a Time-Lapse or Bake a Cake with this Kitchen Timer Panning Rig

Seems like the first thing the new GoPro owner wants to do is a time-lapse sequence. And with good reason – time-lapses are cool. But they can be a bit bland without a little camera motion, like that provided by a dirt-cheap all-mechanical panning rig.

Let’s hope [JackmanWorks]’ time-lapse shots are under an hour, since he based his build on a simple wind-up kitchen timer, the likes of which can be had for a buck or two at just about any store. The timer’s guts were liberated from the case and a simple wooden disc base with a 1/4″-20 threaded insert for a tripod screw was added. The knob, wisely left intact so the amount of time left in the shot is evident, has a matching bolt for the camera’s tripod socket. Set up the shot, wind up the timer, and let it rip at 1/60 of an RPM. Some sample time-lapse shots are in the video below.

Turning this into a super-simple powered slider for dollying during a time-lapse wouldn’t be too tough — if you’ve already got a nice pantograph slide rig built.

Hackaday Prize Entry: FabDoc is Version Control for Project Images

FabDoc is an interesting concept that attempts to tackle a problem many of us didn’t realize we had. There are plenty of version control systems for software, but many projects also have a hardware element or assembly process. Those physical elements need to be documented, but that process does not easily fit the tools that make software development and collaboration easier. [Kevin Cheng] sums FabDoc up as “a system to capture time-lapse pictures as pre-commits.”

With FabDoc a camera automatically records the physical development process, allowing the developer to focus on work and review later. The images from the camera are treated as pre-commits. Upon review, the developer selects relevant key images (ignoring dead ends or false starts) and commits them. It’s a version control and commit system for the physical part of the development process. The goal is to remove the burden of stopping the work process in order to take pictures, automatically record the development process and attach it to a specific project, and allow easy management of which images to commit.

The current system uses a Raspberry Pi Zero with a camera mounted on safety glasses, and some support software. Some thought has certainly gone into making the system as easy to use and manage as possible; after setting up a repository, scanning a QR code takes care of telling the system what to do and where to put it. The goal is to make FabDoc fast and easy to use so that it can simply work unattended.

We saw a visual twist on version control some time ago with a visual diff for PCBs, which was a great idea to represent changes between PCB designs visually, diff-style. It’s always exciting to see someone take a shot at improving processes that are easy to take for granted.

Time Lapse Rig Puts GoPro into Orbit – in Your Shop

The combination of time-lapse photography and slow camera panning can be quite hypnotic – think of those cool sunset to nightfall shots where the camera slowly pans across a cityscape with car lights zooming by. [Frank Howarth] wanted to replicate such shots in his shop, and came up with this orbiting overhead time-lapse rig for his GoPro.

[Frank] clearly cares about the photography in his videos. Everything is well lit, he uses wide-open apertures for shallow depth of field shots, and the editing and post-production effects are top notch. So a good quality build was in order for this rig, which as the video below shows, will be used for overhead shots during long sessions at the lathe and other machines. The gears for this build were designed with [Matthias Wandel]’s gear template app and cut from birch plywood with a CNC router. Two large gears and two small pinions gear down the motor enough for a slow, smooth orbit. The GoPro is mounted on a long boom and pointed in and down; the resulting shots are smooth and professional looking, with the money shot being that last look at [Frank]’s dream shop.

If you haven’t seen [Frank]’s YouTube channel, you might want to check it out. While his material of choice is dead tree carcasses, his approach to projects and the machines and techniques he employs are great stuff. We featured his bamboo Death Star recently, and if you check out his CNC router build, you’ll see [Frank] is far from a one-trick pony.

Hacklet 86 – Time-lapse Projects

“If I could save time in a bottle…” it’s not just an old song, it’s a passion for many photography hackers. Time-lapse photography is a way to show the movement of time through still images. These images are animated into what essentially is a video recorded at a super low frame rate. We’re talking one frame per minute or slower in some cases! The camera doesn’t have to be still for all this, but any motion must be carefully controlled. This has led hackers, makers, and engineers to create a myriad of time-lapse rigs. This week’s Hacklet is all about some of the best time lapse projects on Hackaday.io!

rig-1We start with [Swisswilson] and the simply named Timelapse rig. To say this rig is beefy would be an understatement. All the aluminum parts, with the exception of the gears, were machined by [Swisswilson]. Two Nema-23 Nema-17 motors are controlled by Sparkfun Easy Stepper Drive boards, while an Arduino Micro serves as the controller. The electronics are all housed in a sturdy box which also serves as a remote control. A joystick allows pan and tilt to be manually controlled. The bombproof construction is definitely a help here, as [Swisswilson] is using this rig with DSLR cameras. Combined with a lens, these setups can reach a pound or two.


pilapseNext up is [minWi], who put their script-foo to work with raspilapse. Raspilapse automates the entire process of taking photos, assembling them into a movie, and uploading to YouTube. The hardware is a Raspberry Pi Model B, with a RasPi Camera. The Pi shoots images then uploads them to a Virtual Private Server (VPS). [minWi] used an external server to save wear and tear on the Pi’s SD storage card. At the end of the day, the VPS uses ffmpeg to assemble the images into a video, then uploads the whole thing to YouTube. We’re betting that with a few script mods, this entire process could be run on a Raspberry Pi 2. If you’re really worried about the SD card, a USB flash drive could be used.


SunriseSunsetRig[Andyhull] takes us down to one frame per day with Sunset and Sunrise camera controller. [Andy] wanted to get shots of the sunrise every day. Once converted to a video, these shots are great for documenting the passing of the seasons. He used a Canon point and shoot camera along with the Canon Hack Devleoper’s Kit (CHDK) for his camera. The camera has its own real-time clock, and with CHDK, it can be programmed to shoot images at sunrise. The problem is power. Leaving the camera on all the time would quickly drain the batteries. Arduino to the rescue! [Andy] programmed an Arduino Pro Mini to turn the camera on just before sunrise, then shut it back down. The standby power of a sleeping ATmega328 is much lower than the camera’s, leading to battery life measured in weeks.


podFinally, we have [caramellcube] who added data to their time-lapse photos with Portable Observation Device (POD). POD was conceived as a device to aid paranormal investigators. The idea was to have a device that could take images and record data at a set interval from within a locked room. Sounds like a job for a Raspberry Pi! [caramellcube] started with Adafruit’s Raspberry Pi-based touchscreen camera kit. From there they added a second board controlled by an Arduino Nano. The Nano reads just about every sensor [caramellcube] could fit, including humidity, air pressure, magnetic field strength, acceleration, light (4 bands), sound, and static charge. The Nano allows [caramellcube] to connect all those sensors with a single USB port on the Pi. We’re not sure if [caramellcube] has found any ghosts, but we’re sure our readers can think of plenty of uses for a device like this!

The iPad Controlled Camera Slider

[Daniel] and [Tobias] dabble in videography and while they would love a camera slider controlled by their favorite iDevice, commercial motorized camera sliders are expensive, and there’s no great open source alternative out there. They decided to build one for themselves that can be controlled either from a PS3 controller or from its own iPad app with the help of an ESP8266 WiFi module.

app_live_controlThe camera slider is a two-axis ordeal, with one axis sliding the camera along two solid rails, and the other panning the camera. The circuit board was milled by the guys and includes an ATMega328 controlling two Pololu stepper drivers. An ESP8266 is thrown into the mix, and is easily implemented on the device; it’s just an MAX232 chip listening to the Tx and Rx lines of the WiFi module and translating that to something the ATMega can understand.

By far the most impressive part of this project is the iPad app. This app can be controlled ‘live’ and the movements can be recorded for later playback. Alternatively, the app has a simple scripting function that performs various actions such as movement and rotation over time. The second mode is great for time lapse shots. Because this camera slider uses websockets for the connection, the guys should also be able to write a web client for the slider, just in case they wanted the ultimate webcam.

You can check out [Daniel] and [Tobias]’ demo reel for their camera slider below.

Automated Weatherproof Timelapse System with DSLR and Raspberry Pi

[madis] has been working on time lapse rigs for a while now, and has gotten to the point where he has very specific requirements to fill that can’t be done with just any hardware. Recently, he was asked to take time lapse footage of a construction site and, due to the specifics of this project, used a Raspberry Pi and a DSLR camera to take high quality time lapse photography of a construction site during very specific times.

One of his earlier rigs involved using a GoPro, but he found that while the weatherproofing built into the camera was nice, the picture quality wasn’t very good and the GoPro had a wide-angle lens that wouldn’t suit him for this project. Luckily he had a DSLR sitting around, so he was able to wire it up to a Raspberry Pi and put it all into a weatherproof case.

thumbOnce the Pi was outfitted with a 3G modem, [madis] can log in and change the camera settings from anywhere. It’s normally set up to take a picture once every fifteen minutes, but ONLY during working hours. Presumably this saves a bunch of video editing later whereas a normal timelapse camera would require cutting out a bunch of nights and weekends.

The project is very well constructed as well, and [madis] goes into great detail on his project site about how he was able to build everything and configure the software, and even goes as far as to linking to the sites that helped him figure out how to do everything. If you’ve ever wanted to build a time lapse rig, this is probably the guide to follow. It might even be a good start for building a year-long time lapse video. If you want to take it a step further and add motion to it, check out this time lapse motion rig too!

Remote Controlled Wildlife Camera with Raspberry Pi

If you are interested in local wildlife, you may want to consider this wildlife camera project (Google cache). [Arnis] has been using his to film foxes and mice. The core components of this build are a Raspberry Pi and an infrared camera module specifically made for the Pi. The system runs on a 20,000 mAh battery, which [Arnis] claims results in around 18 hours of battery life.

[Arnis] appears to be using a passive infrared (PIR) sensor to detect motion. These sensors work by detecting sudden changes in the amount of ambient infrared radiation. Mammals are good sources of infrared radiation, so the sensor would work well to detect animals in the vicinity. The Pi is also hooked up to a secondary circuit consisting of a relay, a battery, and an infrared light. When it’s dark outside, [Arnis] can enable “night mode” which will turn on the infrared light. This provides some level of night vision for recording the furry critters in low light conditions.

[Arnis] is also using a Bluetooth dongle with the Pi in order to communicate with an Android phone. Using a custom Android app, he is able to connect back to the Pi and start the camera recording script. He can also use the app to sync the time on the Pi or download an updated image from the camera to ensure it is pointed in the right direction. Be sure to check out the demo video below.
