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...

My glcd arrived today. Got as far as soldering header pins to it and wiring up to the 20x2 on my breadboard. Code changes will have to wait...

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 =...

OK, here's a video. Matrix generation looking OK. Speed here is limited by updating the PC with data. I couldn't get 76800 baud to work - stty command would not accept it. Busby, do you want me to give you some pointers, or just post my code? Like Hippy said, I don't want to spoil the fun. I...

...or you can make your own breadboard adaptor, like I did:

MAX7219/21 16x2 LCD. Most common seem to have 16 pins in horizontal line along the top edge and measure 3.2" x 1.4" (apologies for the non-metric units) Also, could we have stripboard up to 46 strips wide please? (Current limit is 43). I have used this a few times, such as this example where 4...

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?

Sodapep, try drawing your schematic like this:

A cautionary tale: Finally got around to permanently soldering one of my RTC modules to stripboard. I wanted to fix the RTC flat to the stripboard, so this meant that the right-angle headers had to be removed in favour of straight ones. Easy Peasy, I thought... No. When I finally got it done...

Here are a couple of pics of the project that code is from. I constructed 2 rgb led modules which run off a 9V stabilised supply. They are driven by the picaxe via 3 of the darlingtons in a uln2803.

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...

Thanks Alan! I can always rely on you for these questions. So my schematic becomes: Not sure about the inverter idea though. I don't want either device reading the data lines before I have set them up! Paul
