We predict [Brek Martin] got down to construct a handheld GPS and ended up including an mp3 Participant to it. Regardless, it’s fantastically constructed. Hand constructed circuit boards and even a customized antenna adorn this spectacular construct.
The core of the construct is a 16 bit microcontroller a dsPIC33FJ128GP802 from Microchip. It’s a humble chip to be doing a lot. It makes use of a UBlox NEO-6M positioning module for the situation and a customized constructed QFH antenna constructed after calculations completed with an internet calculator for the GPS half. The audio half relies round a VLSI VS1003b decoder chip.
The entire construct is completed with protoboard. The place the in-built traces didn’t suffice enamel and wire wrap wire have been fastidiously routed and soldered in place. There’s a 48pin LQFP bundle chip soldered useless bug type that’s spectacular to behold. You’ll be able to see some good footage on this small gallery under.
The entire unit.
Spectacular.
A customized antenna.
The interface is an ordinary gLCD and an analog joystick with a click on. The mp3’s and map knowledge will be loaded with an SD card. There’s nonetheless a bit of labor to be completed, for instance, he hasn’t found out what to do about batteries but. Should you’re desirous about extra, there are a couple of movies devoted to the construct on his YouTube channel and there are more likely to be a couple of extra.
I assume it comes all the way down to this: did [Brek] add a GPS to an mp3 participant as a result of he will get misplaced whereas listening to music, or did he add a mp3 participant to his GPS as a result of he likes listening to music whereas he’s discovered? Philosophy apart, it’s an exquisite construct.
