    Are you sure there are no markings? Usually it is an arrow on the underside. Sometimes it is some other indicator. Even if there was no marking I’d still buy them you can always find a way to ID the polarity. These days I’m tending to test polarity with a SMD tester to be sure.

  • Product TOL-10719 | about 3 years ago

    I bought around 20 different tips to evaluate for my SMD work - mostly 0603. This 3mm bevel ended up being my choice. If you want one tip to do a number of jobs this is a great tip to have in the arsenal.

    Much later. Actually this is not the tip I use. There are two variants - the one shown here has a solder wettable plating up the side. I use the C3F which is only plated on the face. The C3F is great for flow soldering SMD ICs. I will have to try the C3 on day and compare.

    I finally got around to running this LCD on my 3310 PCB. It is working fine with one minor problem. The SF 3310 display hides to first line of bytes for some reason and I had to offset everything to compensate. The 5110 doesn’t do this as behaves as expected. I haven’t heard anyone else report this so maybe my initialization code is different.
    My fix.

    ifdef lcd3310

    SendLcd(LCDCommand,0x40 | ++RAMY);   //row - row zero is hidden so inc  
    

    endif

    ifdef lcd5110

    SendLcd(LCDCommand,0x40 | RAMY);  
    

    endif

    You could probably make a nub thing out of polymorph. I presume you want a flattish disc with a mm or two space under it. You need a shape which prevents high side loads. If you want rubber sugru could be the shot. Oogoo might work but the stuff I’ve made is much softer than sugru.
    BTW I’ve found laundry starch works fine to make oogoo. If you don’t know what I’m taking about google it.

    It is a pity this display is no longer for sale. The connection method I described earlier is not that hard to do. The PCB version can be seen at the bottom of my 3310 page.

    The 5510 is 2/3 the price of the of the nokia610 131*131 colour display so I’m not sure it is great value.

  • Product ROB-10398 | about 3 years ago

    Mine arrived with both barbs broken off. I think SF needs to find a better way to pack them.

  • Product SEN-09199 | about 4 years ago

    These things will put out very little current. I’m only seeing a few volts maximum on the CRO. The CRO should have 10 meg or so of input impedance.
    I’m hoping to use it directly into an interrupt pin so the micro can be in a deep sleep.
    It will be a while before I set it up properly.

    Mattme: Can anyone confirm that this’ll work in Australia (i.e. SM5100B), and with the local providers SIM cards.
    Thanks,
    Matt

    Matt or anyone else.
    I would also like to know.
    Has anyone done SMS with this shield on Australian networks.
    I want to use it for home security.

  • Product CEL-09607 | about 4 years ago

    higgo: Hi Mattme
    I have just purchased one of these shields. I have it working ok but I can’t get the Arduino to send an SMS from it. I can call it, send it messages and can read the status information it sends out, but no joy with the Duino.
    Have you had any luck.
    regards Greg

    higgo,
    Have you made any progress.
    I’m in the Ipswich/Brisbane area.
    Which network is your SIM for?

    MikeGrusin: It looks well-bonded, I’ll run some experiments and see.
    The partial silver backing on mine was a film which peeled off quite easily and cleanly.

No public wish lists :(
