Shortly after implementing electronics ban from eight Muslim countries, the ban may soon take effect on all international flights to and from the U.S. Homeland Security Secretary John Kelly has recently announced that this decision might take place. The reason is continuous terrorist threats to bring down airplanes. Therefore, the expanded electronics ban could soon take place in order to increase the security of the passengers.
On March 21, 2017, the United States implemented a ban on bringing certain electronic items in your carry-on luggage from 10 airports based in the MENA region. This affects direct flights to the US from these airports.
Shortly after the US announced their ban, the UK followed up with a ban of their own, affecting airports in 14 carriers flying into the UK.
Passengers flying from eight Muslim-majority countries will no longer be allowed to bring almost any electronics in their carry-on. Everything but cellphones and medical devices will have to be in the checked luggage starting today. This means laptops, tablets, Kindles and of course – cameras, can no longer be in the carry-on.
GoPro action cameras are small enough that they can be placed almost anywhere. But the problem with choosing unconventional locations is that you still have to press the record button yourself.
Of course, you could use GoPro’s smartphone app to trigger the camera. But there are undoubtedly times when you don’t want to put your smartphone at risk, or want to worry about your smartphone’s battery dying.
For these times, it’s best to have a backup wireless remote.
Now, with a little know-how, you can create a very inexpensive and incredibly small DIY GoPro remote, saving you from the cost of GoPro’s $65 proprietary remote.
If you’re on the PhotoJoJo mails, you must have gotten that awesome time lapse bit. On that post they recommend the Cannon TC80N3 – a round 100 dollars device that give you the ability to take time lapse images. (It is called Intervalometer, but I can’t even say it, let alone write it and feel good about myself).
There is some great stuff going on at DIYPhotography.net instructables group. This fantastic group is a true demonstration of the DIY spirit that is behind this site. I have talked before on the subject of creating your own flash. In that article Avner Richard explained how to utilize xenon tubes to create some real Watts/Second power flashes. It is a great piece for the ones that are electrically capable.
This guest post was made by Rolf Randby, the same person who wrote the Hot Shoe Adapter article. In fact, This slave trigger was the “trigger” (pan intended) for building the hot shoe adapter in the first place.
There are some Gazillion optical slaves out there. We even one optical slave unit published on this site. So what is so special about this circuitry? Rolf used a PIC (Programmable Interrupt Controller) to give this unit some very nice features: 1. No setup 2. It will work with a red eye setting in your camera. Yep, those annoying red-eye pre-flashes will not trigger the flash, it will “magically know” when the main slash if fired and activate the unit. 3. It will work with all point and shoot cameras.
Those three nice features accomplished with PIC hex code written by Evan Dudzik, from a algorithm by Rolf, make this unit an optimal optical slave unit for P&S cameras. It is the reason I call it the “Very Cool Optical Slave Unit”. Rolf, for some reason, insists on the boring name “STF 1”. I’ll stick with my name – “Very Cool Optical Slave Unit” or VeCOSU :).

See this exploding grape picture? it was taken using a method called high-speed-photography. Yup, this is the same image type as those exploding balloons, squashed tomatoes and bullet shots. The idea is to capture a tiny moment in time, so tiny in fact, that you will not see it with your bar eyes. Trying to capture a flying bullet is not trivial, you can read about the general setup here. [Read more…]
How to take photos like the one you are seeing here. It’s a glass of Champaign, being shot with a BB gun. You can use this technique to take picture of exploding things like tomatoes, watter balloons, watermelons, or even you Canon camera as you smash it against a wall for not understanding the menus (Sorry, could not resist…) [Read more…]
This article will describe my home made sound trigger electronic kit.
I use this circuit kit to take high speed photos like the nice tomato splash shown here (more about high speed photography setups). This circuit is not complicated and the total cost is low so it is even suitable as your first electronics kit. [Read more…]
