i think i will do a reinstall instead

I was mulling that option over. I had it sitting there right in front of me running so I decided to have a go at fixing it. A reinstall for me means redoing my RTC setup, which is a little bit of a pain. Getting the Micro SD card out of this PI is a PITA so I was lazy and didn't make a backup image. I have to use forceps to get the card out with that case. On the plus side, its a really really nice looking case. Just one of those tradeoffs that sometimes happens.

Hmm, looks like my powerboost didn't fail after all? I was cleaning up and gave it one last look over and saw a very tiny thin wire strand laying against the side of a chip. Must have broken off when I striped a wire or something? I'm very careful that way but I must have slipped up. Anyway, I just hooked a battery up and tested it and its working normally again. Grounding the enable Pin turns it off and no voltage out. I was getting 4V before, the battery got shorted to the output. I'm going to leave it on charge for a while, until the battery is charged. Then run it for a bit.

It's been on and off for me. I'll do a bit then get lazy again. Once I get going I usually accomplish something. Lately its just getting started that's the issue. I think things will improve now, it looks like summer has finally made an appearance.

BBC Micro Bit ing today. Nice and sunny, out on my deck. I don't need a monitor for it, it can't use one anyway.

Trying to flash some LED's, like traffic lights. Green, then Yellow, then Red. Seemed like it would be easy, not so much. A lot of the Micro bits GPIO are shared with other stuff. I had to turn off the LED matrix for example to get the pins I wanted to use. The down side to that is no error messages if your code has an error. It just stops or doesn't run. I do it all up in Micro Python but it has to be sent as a hex file to the Micro Bit. I just wanted to do up something simple to show the grand kids.
I got most of what I wanted done. It cycles through the Green > Yellow > Red. I also added 2 10mm LED's to simulate the walk don't walk. They go Green > flashing Red > solid Red. Next step is to wire up a button so the walk LED only turns on if you press the button. Have to take a break though. Neck and shoulders are getting sore. Yard work to do too, lawn needs mowing.

sounds like fun,too much coding for me ..,, I started building another Pi Top,using a 17" old dead Toshiba Qosmio,,,coming along really good, if i don't say so myself.. It has a pi zero w with a breadboard,still trying different layouts

another layout ,still need to dremel away a few more bumps and standoff on the case

Cool!!!

Be careful when you carry that thing to Tim's. You may get "SWATTED" for mistaking it as a bomb.

I can just imagine the looks you'd get at Tim's when you start breadboarding stuff on that solderless bread board. And coding in python. Play some mission impossible music while your doing it lol. Some blinking LED's. Hmm, maybe a four digit display with a count down timer.
Anyway, kidding aside, looks nice there Jack. Those double sided 3M sticky pads are good for holding stuff in place. Easy to remove is the part I like. For when you change you mind on layout etc.
