BTW I'm not laughing at your misfortune just your description of what happened. I do absolutely admire what you've achieved,with a great dollop of envy, because I wouldn't know where to start & I'll admit I fall asleep trying to understand some of that coding malarkey 🙂. Keep up the good work & the down to earth descriptions of when it doesn't go right, all the best.

None taken. :)
The replacement is built and ready for testing tomorrow so here's hoping I don't do the same again. ;)

Want a laugh guys?


Here's a top tip, if using these connectors to connect your 12V then DO NOT try to plug them in live.

If you do then don't be surprised if you let out the blue smoke

The hole on the left isn't meant to be there. :oops: Turns out the positive of the plug sticks out a little so it is very easy to touch the ground of the socket while connecting them. :confused:

So this is me trying to cut out the second Arduino Nano to replace it.

And so a couple of hours later after much swearing, a little red wine and much hackery it's been replaced and tomorrow we'll have another go.
Two things that particularly annoy are, the only reason I used these connectors was to reduce the chances of blowing the second Arduino :oops: and after spending a couple of hours rewiring the LV junction box I was really hoping the next test would work and all I had to do was plug the Arduino in again and test.
Maybe tomorrow.

As I rapidly approach my 6th decade, I'm still very amazed how every day is still a school day.

I think some are ****ed off that they don't know everything, maybe even think they do. But I love learning stuff.

It may mean you still have/create grief for yourself, but finding stuff out is great :D

I found out today that replacing the suspension springs & struts on an F2 isn’t as easy as I thought it would be.

There's not much that is when it comes to working on bits you've not worked on before.

The important thing is, do you still have all your limbs, eyes etc?

If you do, then its a good day.

It wasn't such a good day for 1 of the drivers at the Speedway at Ruapuna here in Christchurch last night. My son went along and I got a call from him quite agitated. A Sprintcar driver clipped the wheel of another at full tilt, smashed into the concrete barrier and the car burst into flames. He watched as the marshals tried in vain to put the fire out with the driver still in the car.

They guy was eventually extracted from the burnt out wreckage and take off to hospital, but he won't be in a good way.

Yeah - I’ve got my limbs, and those suspension struts are not the easiest of things to play with, so a good day.
And the sun was shining.

The nice thing is - it’s not a daily, so I can afford to take my time.

I'm sorry to hear that GG, I love motor sport and everyone knows it can be dangerous but it's always gut wrenching to see someone get hurt.

it never occurred to me that these connectors could be so dangerous but if you look at the tip of the plug in the photo it clearly sticks out beyond the black insulator. This makes it almost inevitable you will touch the pos of the plug to the neg of the socket when connecting them. The Arduino was getting a Gnd from another source so poking 12V into the GND connection like I did was a tad sub optimal. All I could do was laugh when I realised. :)
I'm sad to say my 6th decade is only a few months away. :(

"sub optimal"

Love it.

I shall use this term at work, next time I think I'm clever and doing things correctly when I diagnose faults with a multimeter and "sub optimally" catch 2 wires with 1 prong and blow fuses.

My spanners have chunks burnt out of them where I've been removing wires from batteries and caught both terminals - very "sub optimal" that one :cool:

Mind you I have to drive to Te Anau today (400 miles) to deliver a car to someone and pick up their campervan and drive that all the way back on Monday because someone "sub optimally" fixed a problem with it randomly cutting out.
 
The good news is the new Nano is working and the circuit that detects when the Charger is plugged in also works.
When I plug the charger in the Nano gets 5V and powers two relays which stay on until the charging sequence completes.
There are still a few things to sort out but I'm finally getting somewhere, albeit slowly.
