    Could I use this to multiplex LED’s with enough precision to control brightness? (or rather transistors driving high powered leds)

    I noticed the exact same behavior while tuning the antenna. I have ~55 turns of 32 Ga magnet wire on a 120mm Diameter form made from laser-cut acrylic. I compensated for the probe capacitance with a 100pF ceramic capacitor in parallel with the antenna, and it reliably reads cards inside of 12-20cm from the antenna. I plan switch out for a better quality capacitor, and will report on any increase in range.

    Hopefully this will save people using modern windows computers half an hour of head banging: Don’t bother trying to install the benF firmware using the “DfuSeDemo” method that you see on youtube videos or at seeedstudio.com/forum/

    Instead download the hex version of the firmware here. Next, extract the files from zip, and simply copy and paste them into the plug-and-play hard drive that appears when you plug in the usb and turn on the DSOv3 while holding the down button.

    Here’s the trick: you have to do the files one by one. The disk will immediately disconnect(this is good). when it reconnects, the file you just copied will have a different extension. Start with the LIB, then do the APP next. finally, disconnect the device from the usb port and power cycle it. When it next boots, you should see the benF firmware boot screen.

    Cross-Post from the 4.3" module’s comments page

    Annoying gotcha alert: if you intend to use any of the GUI design tools or modify the programming of the board (which is the whole point) you need one of these adapters

No public wish lists :(
