What's gonna go in here then? I'm not really sure yet, but here's a few things that spring to mind...
Integrator circuit thing
testing out new thumbnailed image tags for this...
ok that's nice! *likey*
(That was the first thumbnailed image in mwuki, after adding that code- previous ones were just inlined fullsize images, which wouldn't be much use for half of these things. Which is why lack of decent thumbnailed image code was a bit of a holdup to this area of mwuki.)
Picture there is only of the bare circuit board and the case. Unfortunately I've still not got photos of the completed Integrator circuit, as I've run out of disk space and camera space and have no SD cards *groan* I'll figure something out soon.
Oh and you may conceivably want to know what in hell's name this thing is supposed to be/do. Well so did a lot of people! And you'll have to wait, so there! And hope that I take less time to write it up than I did to design+build the sodding thing!
The midi dongle debacle (in draft for now)
This would be not just about a project I built the other year, but also an epic tale of midi-related misery (condensed into a paragraph or two probably), and a cautionary tale to remind you that stuff you buy is not always inherently better than stuff you can make yourself. I think I've found all the photos I took at the time (late 2007 by the looks of things). I could conceivably add some more but I've not even uploaded those ones yet.
Possibly even... The Pic Programmer Palaver?
Hard to say, as that's still rather ongoing. My pic programmer adventures went through various different designs, first with a parallel-port based design I found on the internet a few years ago, and had no luck with (though I was able to use the interface side of it to control some LEDs via the computer, which was cool), and then a variety of different designs of my own (half of which I never got to try out as I'd come up with something different before building it) built around the principle of making a serial-port programmer that'd be compatible (at the computer end) with the popular "JDM" serial port PIC programmer. And holy crap if that isn't a hell of a run-on sentence.
It's notable that one of the ones I designed, did actually work... on one chip, that was specified as able to work with a very wide range of programming voltages. Another chip I tested which wasn't, didn't, and unfortunately most of the PIC chips have that sort of range, so it's important to get that right. Of course it's also possible that chip I tested might be faulty somehow, but eh.
Maybe the water detector thingy
Doesn't have as much drama except in that it's to do with my periodically having to empty a bucket of water from a leaky roof in our house, and somewhat arbitrarily inspired/encouraged me to build the aforementioned integrator circuit, though I could likely have managed fine without it anyway.
Probably the LED bargraph display
It's not very exciting at all but I've got a fair bit of use out of it, which makes it good in my book.
Probably various other things I've forgotten right now
And most likely this page will end up as another index type page, with those all having pages of their own. Or most of them would at any rate.
Also some tutorialey things and of course future projects too when they get done. All in good time.
Aha! New in April(2009):
a Midi keyboard design, page is being drafted, not linked yet but I've written quite a lot on it so far. There is no actual circuit yet, except a general design in my head. I don't really have the means to make it ATM, it'd require more stuff unfortunately. Also:
Article on greatly expanding range of IO, as used with above design. Fair bit of writing has been done but needs much tidying up and making a bit more general. Again, is not linked yet.
wholly random linkies
- Hackaday: Migratory box of electronic junk. Neat idea, but probably awkward for sending internationally, what the hell would you put on the customs declaration?!
- Electronics In Meccano: Chocolate Vending Machine, yes a working Meccano coin-operated chocolate vending machine, but I'm not sure I'd call it "electronic" as it's mostly relays, motors and mechanical switches so I'd be more inclined to call it "electromechanical" or something myself. But either way, rather cool.
