Hi all, I have had yet another idea for wind speed and direction sensing. This time more conventional but with a twist. I need help evaluating and designing it. Starting point: one of those really cheap Maplin/Fine Offset 3 cup anemometers. Click here for inside pictures about 2/3 way down the...

All, Just been looking in vain for something I would have thought quite commonly available... Horizontal pcb mounting trimmer pot, with a "wheel" that sticks out from the edge of the pcb and through a slot in the case so it can be operated by finger/thumb. Just like all those volume controls...

Remember this thread? Beginnings of a new idea: Get 5 of those BMP085 barometric pressure sensors. Place 4 of them on the 4 vertical sides of a cube. Place the 5th on the top surface or even inside the cube with a small hole on to allow pressure equalization. Measure the difference between...

I want to run some code written for x2 on m2. The only function used that believe I can't use on m2 is shifting: >> and <<. I only need to shift by 1 bit. Instead of W0 = W0 << 1 I can use W0 = W0 + W0 Which will be pretty quick. But for W0 = W0 >> 1 the only thing I can think of is W0 =...

Anyone ever use this? http://www.amazon.co.uk/gp/aw/d/B0040Z303K/ref=mp_s_a_1_9?qid=1370765288&sr=1-9&m=ACGP07WRXUYXV&pi=SL75 Did you find it better than stripboard overall? How did you break the strips where necessary?

Please help me clear the brain-fog on this one... can't seem to figure it out by reading manuals or searching the forum. Q1. Can pwmout be used to generate pwm signals on more than one pin simultaneously on 14/20m2? Q2: how many simultaneously and on which pins? Pins marked hwpm in the...

If I set up hwpmD (which is on b.5 on 14m2), and then subsequently use dirsB to set the other pins except b.5 as outputs, then use pinsB to set data on those pins, will the pwm continue to operate unaffected? Thanks, Paul

All, Recently took delivery of two DS3231 based I2C Real Time Clock (RTC) modules from China purchased on eBay for about £4 each including p&p...

Hello all, please critique this idea for reusing output pins. I want to use the same pins to drive a 16x2 lcd and drive 5 miniature solenoids. I propose to use 7 pins in total. The solenoids only need to be pulsed one at a time, for a few milliseconds, drawing a couple of hundred milliamps. To...

Some threads on the forum have 5 yellow stars against them. Even one I started a couple of hours ago. You never see 4, 3, 2 or 1 star. Does it mean anything? Or is it just someone clicking something by accident?

All, I want to use a small (80mm x 80mm) polycrystalline (judging by the dark brown colour) solar panel from my "box of bits" to trickle-charge 3 x AA NiMh cells. The solar panel outputs up to just over 6V, open-circuit, when placed close up to a bright desk lamp. Can I just wire the panel...

Hi all, 1 What's the average power consumption of the ERF module? Can this be reduced by disabling when not needed, and if so are there any disadvantages to doing that? I can think of one - over the air programming might fail. 2 Has anyone used a URF module successfully on a linux pc...

I've been thinking about a different and potentially simpler way to measure wind speed and direction versus the conventional anemometer and vane. I'm sure I'm not the first to think of this... A "reed" of some kind, or a whip antenna mounted on a spring, is allowed to bend in the wind. The...

SOLVED: LinAXEPad won't run on Ubuntu 12.10 Hi, I had LinAXEPad running fine on Ubuntu 10.04 LTS, 64-bit. I have now installed Ubuntu 12.10 and done a fresh download today of LinEXEPad and extracted everything from the package (as both a normal user and as root - makes no difference) I see...

All, Having a problem with an new version of an old project. Here's the link, with pictures, code & schematic: http://www.picaxeforum.co.uk/showthread.php?19178-My-first-PICAXE-project-Chicken-lights-Greenhouse-watering&p=229434&viewfull=1#post229434 The problem is this: sometimes the lights...

A year ago I built a circuit to provide light in my chicken houses: http://www.picaxeforum.co.uk/showthread.php?19178-My-first-PICAXE-project-Chicken-lights-Greenhouse-watering&highlight=chicken The 12V, 1.2 Amp-hour lead-acid battery is trickle-charged by a 2.4W solar panel. The 08M2 circuit...

3 of the LEDs in my 4x4x4 cube have failed already! I only built it 6 weeks ago. I have plenty of spares because I bought 100, but they are fidly to replace. So far the failed LEDs have all been on the outside of the cube, thank goodness. So if many more go, maybe I should junk the cube and...
