In this tutorial we’ll explore creating a home made IR trigger capable of firing your DSLR camera out of just a couple bucks worth of parts. Then we’ll show you how to use an iPhone app called DSLR.bot to trigger your camera, record GPS locations, shoot timelapse sequences and more.

Which remote is better — this universal remote or this iPhone? Of course iPhone is better!! It is naturally the best remote you can imagine. It is connected to the internet, so you can check the TV program. It has huge high-resolution touchscreen. And it is always with you. One problem with it: it’s not a remote at all. So let’s turn your smartphone into a remote.

I got a friend who works for small start-up in a rented office. His problem is that they have only a single remote control to operate the parking lot gate. They needed a device that will allow them to open the gate by using the cell phone.
I built a device that connects to a phone line and to a standard remote control. The device is actually a “docking station” for the remote control. When a ring is detected the device will “press” the gate-open button on the remote control.

Allows to remotely manage the heating or cooling of any room. It can also notify, via SMS or phone call, when the sensed temperature falls out the set limit value or the alarm input is active.
All commands related to the control and settings of the device are sent via SMS.
There are three operating modes: forced (M), automatic (A) and enslaved (T); those modes can be set with a SMS or with a local button.
To fully integrate the device with the existing system, our unit can also work as a remote alarm: it has an opto-isolated input at tension level that can be connected to the boiler malfunction indicator and set to be adapted to the different functioning conditions (in order to send an alarm if it receives tension over the threshold or if it is at zero volts); in this way, if the system gets blocked (due to an obstruction in the chimney, the excessive lowering of fluid pressure in the radiators, lack of gas, etc.), the system remotely communicates the fault with an alarm SMS or a phone call.
The alarm on the opto-isolated input is valid only when the circuit is working in automatic mode (A).
That’s not all: there is also a thermal alarm that goes off when the sensed temperature in the room exceeds the limit set by the user, that is it exceeds the maximum threshold or goes below the minimum one; the same as for the one connected to the boiler indicator, the thermal alarm can determine the sending of SMS or phone calls. The circuit can store up to eight phone numbers to which send the alarms as SMSs or simple calls.

Having a hardware interface to your favourite music / DJ / VJ software can really open up doors in your creativity. The most widespread form of hardware control to your PC for such applications is a MIDI based controller.
A MIDI controller can send and receive MIDI messages to your PC, allowing direct control of your software. Not only that, but the controls can generally be mapped to anything your like. So what might be a volume fader for one person can be an effect filter for another.
This article will describe how to build and program a custom arcade button MIDI controller, while trying to keep the price below $100. It is aimed at electronics and programming novices.

robots shares his design for a reflow oven controller: [via]
I have bought [an] oven. The main reason for this was to bake some PCBs. As with every reflow oven, this one needs temperature control as well.
I have baked several pcb without problem with unmodified oven. But that might be luck, as the temperature profile is nowhere near perfect.
I have therefore decided to make some simple temp controller to take care of the whole soldering process. As my oven features fan, I will probably want to control it as well. The controller should not to need any special programmer (mega can by programmed with BP) and the board should be etch-able at home.
