Practice on some scrap SMD parts/boards first, a hot air tool can ruin your day in an awful hurry if you are not experienced with it.

Moderate chaos can be good. ;>))

Glad to hear that you, dog & people are ok, house & Solos can be rebuilt/replaced, family...not so much. Take care, I know the Solo/ArduPilot community sends good wishes & support. Quoting the IrishmanPDX "If you need anything, just ask..."

Thanks for the link. Great video, he did a good job in the 30+ minutes, it took me over an hour for the first one I did. When working with CA glue in close quarters, it helps to use activator ( Locktite Tak Pak accelerator) -->> no waiting for it to set. Put some on the board, and the CA glue on...

In general... remove the chip, clean up, cut the trace, put the chip back on, clean up, add the jumper. So far all 3 work fine. ;>)) I installed OpenSolo & 3.5.x via a modified version of SoloCli. That procedure is not for everyone, and takes a bit of fiddling but it does work. Solex & Matt's...

To switch a PH2.1 to PH2.1 Green you need to be comfortable soldering and working in very close quarters. Procedure: 1. obtain PH2.1 2. open bottom where main connector is, this may require some skill with an X-acto knife. 3. locate jumper pads, that is what the pictogram above is for. 4. cut...

If you look at the pads before you do anything to the PH2.1, you will see a trace between the middle one and the one to the outside of the PH2.1. This is the trace that must be cut and the new solder bridge needs to be applied between the middle and the inner pad. The middle pad is the VCCB of...

Video is always complicated, even on the Solo. After looking more carefully at the Emlid Neutis, I realized it is (probably) their home grown (maybe) replacement for the Intel Edison used in their Reach and Reach RS product. Emlid also has a flight controller, Edge, so Neutis is the logical...

If you are going to re-design the Solo, you might want to investigate a different Companion Computer. This looks interesting: Emlid Neutis iMx6 hardware is somewhat outdated and vastly overpriced for what you get. Needless to say that their (NXP's) support for modern kernels is somewhat lacking...

My Long Galileo acquisition times may be related to the fact that when doing Galileo work I almost always cold start. My house has a metal roof and my window sill antenna I use for inside testing has less than 1/4 sky view and lots of multipath. Once the Galileo constellation is complete there...

It has been my experience that it takes a long time to acquire Galileo sats from a cold start i.e. no Almanac, Ephemeris or Time of day. With any one of the various M8N receivers I have (outside, good sky view, good antenna... these aren't Solo GPSs) I can get a 4-5 sat cold start fix within 30...

Good idea to analyse logs of 3 systems at once. Look for repeated results, truncated data (something ending in 000, 111, 222) as well as bogus positions in between good ones. u-blox doesn't say much to those that don't have a business relation ship (NDA) with them about anything inside their...

The 3Hz rate is the "Solution Rate" not the rate that the data is sent to the "user". The solution rate is how fast the u-blox Cortex M3 CPU can process the RAW data from the RF/IF/correlator channels and derive a "solution" i.e. position. The update rate as set in UBX-CFG-RATE is how fast data...

I calibrate my level & compass indoors all the time. I insure that I have removed my keys from my pockets. I insure that I remove my other stuff which might be magnetic from my other pockets. Check your belt buckle too. I insure that I don't have my phone anywhere nearby. There are several...

The USB port on the accessory board is OTG capable so you can connect peripherals to it and it will power them (as long as the ID pin is set for host mode) or you can plug the Solo into a PC and have access to the file system as if it were a thumb drive.
