This simple trick for creating a signal generator has come in quite handy! It fits a variety of applications and so far has kept my travel bag weight down considerably.

What can be expected from a $15 dollar signal generator anyways? (Hopefully this software “non-compliance” will be fixed in future versions). The only solution at the moment is to simply plug the phone into a charging cable. If the phone went to sleep the signal generator application stopped outputting the waveform! In order to use the signal generator, the phone has to be kept from going to sleep! This is a slightly annoying problem especially since with the display on the phone battery will drain much quicker. There was only one other problem encountered with the iPhone version of software. The final piece of hardware can be seen in Figure 2. Once the headphone jack is soldered, it can be closed up and the alligator leads can be connected either through solder or the set screw depending on the type of connector chosen. The big metal tab on the bottom is the ground with the green and red wires being attached to the left and right channels respectively. Figure 1 shows an image of the headphone jack being soldered with three wires. The headphone jack consists of a right and left channel in addition to a ground. The smart phone signal generator can be built for less than $15! The hardware consists of a single stereo 3.5 mm headphone plug, some wire and then optionally three alligator clips to connect the signal generator to the test device. These signals don’t have components much over 100 Hz at the most! A great example application is for medical sensors such as EKG, EEG and EMG. This seems like a limited range but for most sensors and applications this is actually a pretty wide range. So how can someone turn their smart phone into a signal generator? The simplest way is to exploit the headphone jack that is already present on the phone! There is no need to get fancy and try to interface to the onboard USB! Now just like any engineering project there are limitations on the requirements of what this port can do.Ī standard headphone jack will typically only cover the frequency ranges that a human can hear (20 – 20,000 Hz). Rather than carry around another device with a computer in it, utilizing the computing power and capabilities of the phone allows the device to be smaller, cheaper and weigh less! This is one reason why it is becoming popular to design lab equipment that can be plugged into a smart phone.

The result has been a plethora of portable versions that now exist on the market.įor an engineer-on-the-go, this is very convenient but often times having to bring one more piece of equipment always seems to put the tool bag over the 50 pound limit. In recent years these lab tools have not only decreased in size but also in cost. They are perfect for testing inputs on a new hardware design and verifying the behavior of a circuit before connecting all the pieces together. Signal generators are a handy thing to have around the lab.
