Electronics, at last

When I opted to do the SKE course (it was added as a condition of my SCITT offer because I asked it to be) it was mainly because I don't know enough about electronics and “systems and control”.  I've been waiting to get into this stuff, and as we did I have started to feel like I would be OK with teaching it – which is the whole point, in the end!

We started off looking at currrent, voltage and resistance, building circuits on breadboards and trying out multimeters.  We moved on to thinking about input, process and output, using a transistor and a sensor diode.  There was a lot of brain work but I was happy to feel that as we worked through it step-by-step I could see how things worked and mostly could explain what was going on.  There's more tomorrow.
