  • I see pcDuino3 supports a touch LCD using LVDS connector. Where do we find these touch LCD’s with this type of connector.


    This is a product that has been out for awhile. The CB210 combines a CUBLOC PLC controller with a USB interface on an “Arduino” format circuit board. Has 1kB available for your ladder logic.

    Anyone tried it?

  • +2 for Sketchup. Been using since 2008 and no complaints about its functionality and versatility. Perfect for modelling. There are also some tips found on the sketchup blog / newsletters on what to do and add-ons are available to get the right output for 3D printers, although getting this right is a little trickier.

  • We successfully applied the Electric Resistance Welding technique to attach sensors to the standard (uninsulated) conductive ribbon without problem.

  • According to Atmel ATSHA204 datasheet: There are 88 bytes in the configuration zone which contain manufacturing identification data, general device and system configuration, and access restriction control values for the slots within the data zone. Byte 14 (I2C_Enable) uses “bit 0” to tell you whether chip is set as either I2C or as single-wire. If bit 0 set as 0 then operates in single-wire interface mode, or set as 1 then operates in I2C interface mode).

    I checked the Arduino library and it has defined “ADDRESS_I2CEN” for this purpose, but it appears this is not used anywhere in the code… but then the writer does say “it is a bit bare-bones now”.

    So if you really wanted to be safe may be worth testing which protocol is being used in your code, as datasheet does say “Communications with the ATSHA204 achieved through one of two different protocols, and selected using the part number that is ordered”.

  • Just ordered one and it works quite well. However, both the connection wires were damaged when it arrived - appears to be pinched at different locations, especially at the point where the two wires come out at the back of the transducer. I think the wires are not strong enough with weight of transducer(thicker wire probably required - although through hole diameter limits options). Have others found the same with wires.

  • Does anyone know how fast you can write data to the SD card (speed in msec) using this product. Can’t find any specs. I read somewhere for another microSD type datalogger that they could achieve about 44 msec through serial port.

  • Its seldom I offer comment, but having just purchased and tried these I have to say that these “cutters” can’t cut the mustard. If you literally say what they do, then I suggest they should be called mini diagonal wire squashers. A little blunt… mind you casting my eye again on the description given above I think it’s correct they’re really solder cutters and not wire cutters.

  • I’m looking for a short cut to create a simple Wiegand Signal Generator and thought this kit might be a good starting point as it already gives the pulse at 0 to 5V.
    So basically want a simple module to produce me a square wave pulse at intervals that match the Wiegand protocol - pulse width (Tpw) range 20 μs to 100 μs & interval width (Tpi) range 200 μs to 20 ms.
    So instead of fiddling with potentiometers, I wondered would anyone know what resistor values I should replace them with. Also is there any clever way to split the signal for my Data 0 and Data 1 lines.
    And if there is any other components settings to build this interface please let me know - e.g do I need to have a start and stop delay, if so what is needed to do this.

No public wish lists :(
