After about 4 years, I've resurrected the project and finished it off. It now measures current, voltage, power, harmonics, waveforms, power...
I came home today to find a cheap chinese 'ICD 2.5' (whatever TF that is) waiting for me. Plug it in all excited and see what happens. Gah....
Doh. Didn't think to check. Ta. The 3.3V PICs all see to be fully 5 V tolerant on the I/O pins. Similarly, most LCDs e.g. HD47780, are fully...
Well, as I'm lazy, I've decided that the "brute force and ignorance" approach to MCU development is definitely the way forward (after an abortive...
Well, MPLAB and C18 work fine-ish on Vista (MPLAB crashes on exit, if you ask it to save the workspace before it quits) but other than that it...
I'm looking for a replacement for my old parallel port programmer. What's the difference between something like a PicKit2 and an MPLAB ICD2?...
Thanks all. Just thought I'd update. It looks like I've solved the glitching issue. I changed the software to bypass DirectX and access the...
Just an update. I'm still tinkering with getting voltage monitoring up and running before I add current. I should be getting a new potential...
Well, I changed the transformer and the performance is drastically improved. The waveform now looks 'nice', and the distortion figures have gone...
There isn't much of a schematic. Essentially it's just a standard 230:9 V transformer. In fact, it's just a main adaptor from a now defunct modem,...
I had an idea to try and make a more fancy version of those 'kill-a-watt' watt meter things - one that would interface to a PC, so you could get...
Not sure. The datasheet only gives information about soldering. The thing is that the slug is very small, and the high-end K2s produce a lot of...
I was supposedly upgraded on 25 April. However, I'm still only connecting at 1152/288. Attenuation (U/D): 7/16 Margin (U/D): 25/31 I spoke...
Can you hand solder these? Looking at the datasheet, they're supposed to be reflow soldered. The problem I see is soldering the heat slug to...
I've got most of mine from luxeonstar.com. They're not in the US, so your yankophobia doesn't need to be an issue. They are however, in Canada....
You misunderstand what the data sheet says. It says the capacity is 1.5 Ah (1500 mAh). But then goes on to say that the max current is 250 mA....
It's also worth asking www.olimex.com/pcb if they could do it. Their prototyping service is quite cheap, and they do free panelising and cutting....
Governor, or better, Guv'nor This one sounds very much like a Polish swear word - should be good for a few laughs. Or you could confuse...
But can only supply a max current of just over 100 mA. It sounds like that might not be enough for this project.
Hmm. I suspect you need to consult a less, err, mainstream website. Perhaps one more related to things beginning with w and ending in z. As I'm...
