Radio Receiver

If you never got the chance to build one as a kid [JoOngle] takes you through the steps to build your own radio receiver. Details are a bit scarce but it’s nothing your friend Google can’t help you out with.

2-axis motion timelapse photography

[Milapse] picked up a motorized telescope base a few years ago. He’s using it to add motion to time-lapse photography. The base provides two-axis rotation controlled with a handheld keypad. Custom firmware and a bit of software allow for computer control. [Milapse] is pretty well-known in the time-lapse photography circles of the Inter-web. He’s posted a ten minute videoRead the rest

Hackaday Links: Sunday, November 29

Sometimes we wonder if we’re making good choices with PCB layout when using EagleCAD. Watch how the pros do it with a video of an hour-long Adafruit PCB layout session compressed into seven minutes.

[Elijah] documented his RepStrap build. This is a chicken-or-egg project in that RepStrap machines are built without the assistance of an already existing RepRap.… Read the rest

Time-lapse courtesy of Arduino

arduino-time-lapse

[Ross] put together a small package for use with time-lapse photography. The Nikon camera he’s using can snap a picture when it receives an IR command. [Ross'] solution connects an IR LED to an Arduino to generate this signal. The delay between frames is set with a potentiometer that is read in through the ADC. This is quite a bit … Read the rest

Time lapse light sculptures

time_lapse_light_sculptures

[Jared] sent us a feature he posted involving time-lapse photography and an LED. Using a custom built aparatus an LED is moved on two axis’ during a long exposure of around thirty seconds. The frame is wood and PVC with two gearhead motors powered by AA batteries to provide the locomotion. The LED is powered by a 3v button … Read the rest

Toyaanisqatsi: time lapse control using LEGO parts


A simple panning motion can add impact to the already-dramatic effect of time lapse photography. To accomplish this, frugal cinematographers sometimes build [Rube Goldberg] contraptions from clock motors, VCR parts or telescope tracking mounts. Hack a Day reader [Stephan Martin] has assembled a clever bargain-basement system using an Arduino-driven stepper motor and a reduction gear system built up from … Read the rest

Making a tilt-shift lens

tilt

[Bhautik] is on version 2 of his tilt-shift lens, and wrote in to share what he has learned. Some aspects of the design on version 1 made it a bit quirky to use. You had to hold the lens in place, manually adjusting the focus. This meant that no two shots were the same. Since [Bhautik] wanted to do … Read the rest
