SMALLEST - WIRELESS - TETHERED DIY LIFEVIEW REMOTE CONTROL (for Nikon -- works with other cameras too) Projects - DIY SC-28 Flash Cord clone. /home/ak/projects/diy-sc-28-flash-cord-clone So I wanted a SC-28 cord for my camera and flash but didn"t want to pay that much for just two connectors and a cable so I decided to make it myself. Didn"t have anything important to do this weekend so here is the result. The flash shoe also has the locking hole for the flash so it stays very firmly in place. First I started by cutting and shaping a piece of 1 mm thick aluminum to get a body for the flash shoe and after that I started building the connection part of it on a prototyping board (dot coppered).
Camera side of the thing is done from various pieces of plastic superclued together. The connectors are PS/2 connectors (or mini-din, used in keyboards etc). Tools used: A drill press (a normal drill would have been suitable), a hacksaw, small knife, set of files, few pliers, two clamps (to press things together when applying glue), soldering iron. Edit, 16-Dec-2007: I found my 3-meter PS/2 extension cord and it works perfectly with this. Programmable Slave Trigger - 017. Programmable Slave Trigger - 004.

Thanks to Strobist I was looking for a cheap power-controlled flash because the ancient Vivitar 728 Zoon N in my collection is a dedicated unit that can only fire at full power on a non-Nikon camera. Buying another flash was certainly an option, but the strobist-way is to solve problems by thinking instead of throwing equipment and money at then.
So let's just emulate a Nikon camera (and add an optical trigger while we're at it)! EOS-20D, 1/250s f/8.0 ISO 100, internal Flash -1EV, external flash on lowerst power I have no idea if this little project will work with any flash other than my particular one, so the ususal disclaimer applies: May or may not work for you. If any of this destroys/damages your flash, camera, remote trigger, house, life, etc/ruins a once-in-a-lifetime photo opportunity/gets you arrested for carrying around something that looks like a bomb/etc. it's your own fault and not my problem.
You have been warned. Nikon hot shoe pinout Random notes Usage of the DIP switches: A spot of DIY & bargain hunting. Www.doc-diy.net :: Compact RS232-TTL converter. Update: There is a new low voltage version of the MAX232 called MAX3232. I updated my converter revently and it works fine with 3V from two batteries now. When programming microcontrollers debugging is inevitable. Options like JTAG or DebugWIRE exist, but they are usually too expensive for most entry level DIYers. Another simple and controller-independent option is to utilise the USART for debugging.
It's integrated into nearly all of today's microcontrollers. This article describes how to build an extremely compact converter circuit built around the MAX232. The circuit is shown in the images below. At this point I'd like to mention that soldering SMD parts is not as difficult as it might seem. Example code The source code below can be used to test the proper functioning of the converter. 38400 baud/s data rate 8 data bits 1 stop bit no parity bits There is a variety of terminal programs for serial communication.
Download All files necessary to build the converter are provided below. Links. Www.doc-diy.net :: camera remote release pinout list. CanonNikonPentaxOlympusSonyPanasonic/LumixSigma Most DSLR and SLR cameras can be triggered remotely using a release cable. Unfortunately the connectors used for the external release have rather exotic shapes. Below you will find the pinouts for the common camera types. The standard solution consists of three wires: ground, focus and shutter. To focus the camera the focus wire has to be connected to ground. To release the camera both wires have to be connected to ground. Canon All Canon EOS cameras are equipped with a remote release connector. 2.5mm Jack Connector This connector is used with the EOS 350D, 400D, 450D, 500D, 550D, 60D and the 70D.
N3 Connector This connector is used with the EOS 10D, 20D, 30D, 40D, 50D, 5D, 5Dmk2, 5Dmk3, 6D, 7D and all types of the 1D. Nikon With three different types, Nikon is the unbeaten leader in inventing remote release connectors. This type fits the D70s (not D70!) This type fits the D90, D3100, D3200, D5000, D5100, D5200, D7000, D7100, D600 and D610. Sony. Www.doc-diy.net :: delay circuit for photography. This article describes how to build a simple uC based delay circuit for photographic applications like drop or high speed photography. It can be used to control the trigger lag of cameras and flash units, generate a periodic trigger pulse or even control magnetic valves. The input and the three outputs of the circuit use standard 3.5 mm stereo jack connectors, so the delay element can be looped easily into your existing trigger circuitry like the SmaTrig for example.
Cascading multiple delay devices into more complex circuits is easily done. As simplicity was an important design goal, there is no text display or a sophisticated analog input stage. All resources to build a copy of the delay are provided below in the Download section. Usage A short press of the on/off button switches the circuit on and off. Standard delay mode Directly after programming the AVR your delay will work as described in this section. Delay / pulsewith mode Interval timer 100x slow mode The Circuit C code Download.
