I only used this for my stripboard board and with the production systems I soldered the Nano's directly in.
Quote:My Nano with CH340G chipset arrived yesterday and I tried manually press fitting it into a "Turned Pin" / "Precision" 40-pins socket (which I have not soldered to the board yet) but it would not go in (too tight, hurt my fingers) whereas it did go into a standard / cheap 40-pin socket (the ones with the weak bendy thin legs) but with considerable force needed from my fingers.
Yep, these are the same as I mentioned above and they are always a tight fit.
Quote:I was thinking that maybe I could cut up a 40 pin socket for use on the actual PCB but then there would only be one supporting "bridge" of plastic at one end of the board, and I always use those bridges to lever against when I am removing the chip from it's socket.
That will be fine, once it's soldered in, it's strong. You can lever either against the other end, or against the PCB.
Quote:I can only find Turned Pin 30 pin sockets in UK, and they are too tight for this style of chip (with the Nano having it's pins that stick up into your fingers) whereas this type of socket did allow me to fit my Nintendo / Ricoh RP2C03B PPU in rather nicely when I was doing my Nintendo NES RGB modification.Yeah, I couldn't get a Nano in one of these either or any other DIP chips have.
Quote:I can find a NTE435K30 from Radioshack that looks like it would do the job nicely, but I don't seem to be able to obtain these in UK and I can't order from Radioshack in USA? and there are none on Ebay that I can see.
As above, if you're dead set on using a socket, just (very carefully) cut the socket back. I broke the first one doing so with small sidecutters.
I'd recommend soldering the unsupported socket pins in place with the Nano (or another DIP chip) in the socket to ensure the socket stays in shape.
Quote:Finally my FO1081 had a wind speed glitch of 103Km/h tonight, the 2nd one in 2 weeks, with 2 different anemometers!
Alistair, that's one of the key reasons why I took on this project. Another was the Wireless connection was real flaky, even while being very close.
BTW; Maybe you should start you own go to whoa thread, just so it's easier to follow for other readers and people who are here just to poach Werk's code
OK then I just started my own build thread at ;-

I don't fancy levering directly against the PCB for getting the Nano out, so I'll likely just glue in a section of plastic where the end "bridge" is missing when I cut up and re-use an old low precision / non-turned pin socket.
My wireless connection to the FO 1081 doesn't seem to be a problem, but the glitches sure are. Note that my friend who used to run the Davis VP1 also had glitches in temperature and relative humidity quite often (like once a day), maybe the combined temp. / humidty sensor was faulty, or maybe there was a glitch in the wireless link, who knows. Often it would not connect to Cumulus either through the Serial to USB converter. I'll be glad to get a WD Pro2 up and running with no glitches LOL.

Fine Offset WH-1081 (Maplin N96FY) at present, soon to be WDPro2 I hope so that I can have Solar & UV graphs as well
