Cordless drill conversion to LiPo power

Posted by Mark Spencer    Categories:

You are about to finish your project, reaching out for your trusty cordless drill just to find out that the battery is empty, &$*!@!$. We all know this happens just too often. Batteries used in cordless drills are usually of Ni-Cd chemistry which has high self-discharge rate. This means that chemical reaction inside the battery is reducing it's charge without any connection between the electrodes, just by sitting on the shelf. Ni-Cd are especially prone to this losing it's charge pretty quickly. Another problem is that these batteries are usually of low quality with low number of possible charging cycles.

Good monitor is the paramount in FPV flying and first thing to carefully choose, so is Fieldview 888 one of those? Does it goes to blue screen and is it bright enough for FPV?

DTF UHF 1 Watt long range receiver

Posted by Mark Spencer    Categories:

You might ask yourself if the title is correct, 1watt receiver? Aren't receivers the one that receive the signal not transmit? Well, it's a bit misleading, since DTF UHF 1 Watt long range receiver is not receiver only, it's transceiver.

Transceivers are devices with dual purpose, receiving and transmitting usually sharing common circuitry or housing.

There surely are cheaper alternatives but TGY-306G-HV is good "bang for the buck". Thanks to it's dimensions it's usually used as drop in replacement for cheap Orange servos and it surely is an upgrade in terms of quality.

Taranis Battery

Posted by Mark Spencer    Categories:

New Taranis RC transmitter from FrSky is maybe todays best bang for the buck, but why on earth did they design it for obsolete NiMh battery packs. Taranis battery that comes with transmitter is only 800mAh and since it's NiMh with high self-discharge rate. This means you have to charge it every time you are planning to go to the field.
