For the past couple of monts GNSS-disciplined energy computers have been taking on a large percentage of my craft energy
Published by John Miller
Building and distribuiting the TimeHat went well, plus it gave me a touch of added capital to dig into two things that i would n't have been able to normally, like picking right up some "real" GNSS timing modules! The machine I became more interested in was the Nokia FYGM, a GNSS timing device meant to assist Nokia cellular webpages gear. The FYGM has a u-blox LEA-M8T, one of several much better timing-focused u-blox modules readily available. Lots of people get these (alongside) timing segments from decomissioned cellular sites through Chinese scrappers and recyclers simply to collect the device, but i needed to make sure they're as "along" possible.
Unlike typical hobbyist GNSS modules, the FYGM have a some extra devices about it, specifically an 8051 MCU. I've additional information on this regarding wiki, right here, and so I'll bare this quick. To begin, you need to simply emancipate the M8T with this panel? You will find some grounds:
- I do not like to build a brand new carrier for your M8T
- The initial board keeps good quality electricity items the M8T and productive antenna
- It produces exceptional antenna security circuitry
- The incorporated aluminium case is truly great
- The reputation LEDs (powered from the MCU) are helpful
- As soon as board footwear, it's not hard to obtain the MCU regarding the method
That MCU, the 8051, started as the greatest thorn within my area. Before I got one of these devices during my possession all I had to visit away from was ebay list photos and several content regarding the TimeNuts mailing list, but that has been sufficient to start out. Besides antenna insight, the FYGM have an added connector - a 12 pin DIN amphenol-looking thing. Luckily all the FYGMs I have discovered on the market inclide a completed cable tv to mate using this (using an HDMI connector about variety product end, with CAT7 as wire it self), or else this connector could be a real soreness to handle, becuase it isn't an amphenol, or anything that appears to be generally speaking offered.
