Its been quiet this last couple of days on this website, but thats not because we’ve not been doing stuff!  As I’ve said before, like the swan, LEAF sometimes goes awfully quiet, yet underneath…

Yet more stuff on the board.

Yet more stuff on the board.

So, here you can see the board as it currently stands.  You may notice the new resistors running down the right hand side of it below the smoothing capacitor then ‘vero pins’ to the right of them.

These are the various outputs that will very soon connect to another board that will have indicators on.  And yes, due to popular demand, there will be blue LEDs.

While all this has been going on, I’ve also been working on the box to house this in, along with the battery.

I had made a box some months ago, but in the end, never used it ‘in rage’.  Well, it was time to resurrect it and make a new lid.

Old box, new lid.

Old box, new lid.

Here you can see it in my kitchen (…also known as ‘The Workshop’…) with a new lid, not yet painted with the awful blackboard paint I seem to have been given.

You’ll also notice that there is a square hole (…with rounded corners!..) in the top of the new lid.

Underneath this is a clear perpex panel.  This panel will be sprayed black from the underside later this afternoon and there will be small circular ‘dots’ left unpainted through which you’ll be able to see the various LEDs mounted on a display board underneath.  Also on this top panel will be the on/off switch, the 9-pin serial socket to connect to the computer and the little ‘programming’ switch to tell the board I want to program the chip inside.

The main circuit board will be mounted under the lid on the opposite side from the display board, and the ‘grunt’ electronics which handles the raw power coming off the bike is mounted on the end cheek you can see with the handle visible.

This shot shows a close-up of just some of the connectors to this section.  The two larger ones to the left are from the bike and to the battery, while the line of smaller ones feeds the individual lamp outputs.  You can just see the start of the big sensing resistor block towards the right and the choke/inductor is the circular round thing screwed down towards the middle.

Of course, I could have shown you a full shot of the entire electronics mounted on this end cheek, but anyone with any electronics knowledge would see what I’ve done and be able to copy it.  While we’re all for ‘shared knowledge’ and the rest, we feel that given the amount of work we’ve put into this, then anyone copying it should at least talk to us before attempting this.

Anyway, I’ve wittered too long.  I’d better get on…
