Joe Smith's Portable Charging Station with Jeti Wireless Telemetry!!!
Telemetry technology has allowed the Radio Control industry to come a long way, and Jeti's Telemetry System is no exception! The Jeti Telemetry System of transceivers and sensors allows you to monitor multiple parameters occurring in your aircraft in real-time, but why limit the telemetry to aircraft only?
Impressed at the fast setup of a friends system, Joe Smith, a Jeti USA Team Pilot, was in search of the perfect charging setup. As Joe set out to build his own charging case, he was determined to solve the problems that have plagued RC enthusiasts for quite some time. When charging batteries, several issues can arise, no matter what setup you use. These problems can be as simple as a bad connector or as complex as a corrupt circuit on your charging board. If, or shall I say when (since these problems will occur at least once in a hobbyist's lifetime), a problem occurs the result can be troublesome. You can end up with batteries that do not have a complete charge, are over charged, or have cells that are extremely unbalanced. In extreme cases, your battery pack could overheat and ignite. In the past, the only solution was to monitor the entire charging process. Obliviously this is not an easy task as batteries can take anywhere from 15 minutes to 2 hours to charge.
After switching to the Jeti DS-16 Radio, Joe had become quite familiar with telemetry technology and its uses, which led him to the question "If I could monitor and setup alarms for the temperature, voltage, current, and mAh usage of everything in my airplane while it was in the air, then why couldn't I do this with a charging case?" The answer was that he could. We know that through the use of a MUI sensor we can now monitor voltage, current, and mAh usage between each charger and power supply, the voltage of each battery, the current going to each battery, and the mAh that have been put into each battery. Jeti's MULi 6S sensor allows us to see the voltage of each cell in each battery pack, and the MT125 sensor shows us the internal temperature of each charger as well as the temperature of each 12V power supply. Now that we know what we can see, the question remains how do we see it. For that, there are a few options. Of course you can view all this telemetry information directly on to your Jeti DS or DC transmitter, but that may not be most practical solution. Jeti's Profi Box is a device, about the size of an Apple iPhone 5, that with the use of a Jeti receiver can receive telemetry data. This allows the ability to monitor your charging batteries, with the convince of mobility. Using the JetiBox programming feature in the Profi Box, you can program audible alarms for each parameter you are monitoring.
Therefore, if a problem should arise, you will know instantly. The advent of modern telemetry systems have not only given great insights about our aircraft during flight, but have simplified the processes that were once troublesome. With the line of Jeti Products, these systems are easily available, and as we are learning, the possibilities are endless.

AMA Expo, Ontario, California, January 10-12, 2014!!!
Expo 2014 was bigger and better than ever with more than 100 exhibitors featuring over 230 booths. This includes 18 new exhibitors showcasing and selling the latest in model flying products. The swap shop was bigger too with 35 tables of great finds and one-of-a-kind items. Add special guest speakers, an AMA membership meeting, FAA forum, flying demos, and exhibits such as a Spruce Goose scale flying model with a 25-foot wingspan and you have a great Expo experience!
