  • We did the low tech version to a friend... We went to the pet store, to the reptile section and bought 2 boxes of live crickets. These cricketts where then released in his house, predominantly the bedroom.

  • I'll start by saying I do love Fluke equipment, but this is unfortunate, although I am glad to see Fluke respond so well. I carry several different Fluke meters with me every day for my job. I work all over the world and I really couldn't do my job without a good quality multimeter (aswell as a few other instrumentation testing tools). For the last 12 months I have worked on many projects in China. This is where I constantly encounter the "Flake" multimeter. The first time I held one I couldn't tell the difference between it and my workmates Fluke 179... until we turned it on. It took a few seconds to display anything, and the screen would only update every few seconds. We later discovered this particular copy had no fuses for current measurement and a few other scary things. I have to look after my meter, it has to be inspected on a regular basis and calibrated every 12 months (granted I am using it on some high energy supplies in countries that aren't the safest and then use the same meter for checking high precision instrumentation) What am I trying to say, I guess Fluke has got some real problems with copies and it is potentially dangerous for people like me who see the fluke brand and get that warm fuzzy trusting feeling and want to "Test all the things!!" but I dont see how or why a sparkfun branded meter would be considered a threat to Fluke's name, market or other people's safety. While I am sure the Sparkfun meter is great for the electronics enthusiast and definitely well priced (the first meter I had cost $14 about 16 years ago and was terrible) but anyone who decides to test a 1000V supply with a $15 meter should probably think twice.

  • Well, I didn't read the description well enough. Micro A... Never seen a device with a Micro A socket. While this might be some kind of standard written on white paper somewhere how is this a practical design? Most people want a OTG cable so they can use their phone, tablet, media player or other device that supports OTG that has a standard Micro B socket that is used for everything. Lucky I already have a spare and maybe i'll chop the sparkfun one up.

  • I really wish Digi hadn't put restrictions on what zones you guys can sell this module... dealing with our local industrial electronics mob... we have to ring for a price and it is ridiculously high...

  • I remember being laughed at while studying for deciding to use a PIC in my micro project rather than an AVR because "PIC's are for hobbyists", this was well before the days of the Arduino, the poor old PIC carried the same stigma that gets put on the arduino now. Don't get me wrong, I love AVR's, ARM's etc. But I choose the appropriate micro for the task and not the Micro I am familiar with, and there just seems to be a PIC that fits exactly what I want to do more often than not.

    Very often now days too, I pull apart the new things that come into the office and find that very often there is a little PIC sitting at its heart. PS.I haven't looked into it further but MPLAB X is using Net Beans, which is mutli platform, so maybe the days of PIC being supported for Windows only may have dissapeared

  • That is a fantastic idea, I have often fantasised about making a rover to drive around the moon with... but as always it never got passed a fantasy as I don't have the means to get it there. But a small, rugged solar powered boat (or similar) with a satelite modem, gps, compass, sonar and lots of cameras etc etc you could send off on fantastic voyages, granted it'd cost a lot (Especially the satelite bandwidth) but just imagine how significant it would be to the open source community, then fit the boat out with a little rover or something to go on shore or a quad copter even. Totally awesome

  • you could do that and it would be very cool,
    you were right in saying that the light wont "leak" out the sides, its called complete internal reflection (don't quote me on that, it's been 10 years since high school physics)
    The only thing you would have to make sure is that the fibres are still completely enclosed, as they will pick up light from the side and pass it on to the ends, effectively jamming your signals

  • Making basic low power transistor amplifiers can be quite easy once everything "clicks" and you get the feel for things (With BJT's anyway, MOSFETS are a whole other world). When you want to go to 2 transistors or matched stereo etc thats when things start to become painfully complicated.

  • Awww, but I just made some specially designed cockroach shape charges...

  • I love this chip, it is at the heart of many of my latest creations and will be in many more I imagine!
