Sold(i)ering on.

Today, I’ve been putting the finishing touches to the new board, viz:

New board complete.

New board complete.

If you compare this with the last shot of it, you’ll notice a new 8-pin i.c. (Integrated Circuit) on the right handside, and if you’re really eagle-eyed, you’ll notice more ‘gubbins’ in the shape of another transistor nearby, then over to the left of this shot, you’ll see yet another transistor with associated dividing resistors.

The first transistor is the main FET switching transistor, while the last one is a ‘range’ selector which sets the input range for sensing the input voltage coming from the bike.

Now, I just have to fabricate another ‘adapter’ for the pratty little 8-pin SOIC current sensing chip (…A MAX4080 if you’re interested…) so it will fit in the empty socket.

When that’s done, I have to make another sensing resistor bank, then…

…well, its in the box with it.

Then test it.


Some of the First Fruits (apples from Meynell School grounds) these were taken to Early Days Centre at Palgrave Road.

Well we had another good morning of harvesting today with another couple of trees from a garden near Yewlands Technolgy College. A small but merry band (me, Angela and the two children to be precise) managed to collect just around 40-50llbs of cooking apples …. we’re hoping to go back later this week and finish the job by harvesting the eaters from the other tree.
All the apples are safely stored for the time being at Mount Tabor Methodist Church, and will soon be distributed on the estate through the usual sources.
Priority for next season is getting ourselves a fruit press so we can juice those apples that aren’t at their best anymore – and of course more of the jam and chutney making that has been discussed in the past. So if there’s any keen amateur jam and chutney makers out there – please get in touch. I’ve got the apples, and the jars, we just need you!
