If your answer to the question “When did you last shoot a roll of film” is “Less than two decades ago”, the chances are that you’re a camera enthusiast, and that the camera you used was quite old. Such has been the switch from film to digital, that the new film camera is a rarity. Pentax think there may be an opening in the older format though, as they’ve announced in the videos below the break that they’re working on a fresh range of film cameras to serve the enthusiast market.
We don’t know the economics of the camera business, but we’re certainly interested to see what they come up with. In a world that’s still awash with cheap film cameras from a few decades ago, whatever they produce will have to be good, but given that it’s Pentax who are making the announcement we’re guessing the quality will be of a high standard.
Perhaps more interesting in the revival of interest in film is that it comes at a point when designing and making your own camera has almost never been easier. If you’re bored waiting for the new Pentax, make your own!

Most DSLR cameras have the ability to take pictures at set intervals, but sometimes the menu system can be clunky, and the options are often less than ideal. [Achim] is a big fan of time lapse photography and has been hard at work creating a hardware-based intervalometer to suit his needs. He has just finished the second revision of the controller which is just about small enough to fit inside the housing of a 2.5mm stereo plug. The timer is not 100% universal, but so far he has confirmed it works on Nikon, Canon, and Pentax cameras.
Based on a PIC10F222, the circuit’s operation is quite simple. Once the dongle is connected to your camera, you simply need to take two pictures anywhere from 0.4 seconds to 18 minutes apart. The intervalometer “watches” to see how long you waited between pictures, and proceeds to take shots at that interval until the battery dies or your memory card fills up.
As you can see in the video on his site, the timer works a treat. If you want to make one of your own, swing by his site to grab schematics and code – it’s all available for free.
*Whoops, it looks like we’ve actually covered this before. Our apologies.
Apparently Pentax DSLR cameras have a remote shutter option that used infrared signals. [Pies for you] gathered up several different hacks and built a method of triggering the camera using custom audio. He put together the dongle above, just a headphone extension cord and two IR LEDs, which plugs into the headphone jack of any audio device like an iPod or an Android phone. When you play back a file the audio signals drive the IR LEDs. This is completely worthless unless you craft your own audio file using the correct frequency, duty cycle, and bit encoding. [Pies for you] did just that and got things up and running. Looks like the system doesn’t do so well with MP3 compression, but take a look at the waveform analysis that he posted and then make sure you’re using a lossless format.
