Hey, Just updating the blog wth a few bits and pieces. Nothing special, just PWM driving an IN13 nixie bargraph display. http://nerduino.word...nixie-bargraph/ Les

No, it's not a shady pyramid selling scheme - it's a trapezoid model! MS are giving away VS2010 Pro, Blend, SQL server and Win 2008R2 to "professional developers" via the websitespark program. http://www.microsoft...b/websitespark/ Of course, you're all professionals aren't you (ahem, cough cough). Students can get even more through dreamspark. https://www.dreamspark.com/ Happy Christmas.

Hey Was just reading this from a few years back http://www.arduino.c...um=1227128468/0 Seemed like a more powerful processor with a less powerful set of tools than netduino. Got me wondering why netduino is ARM7 based? Can someone explain the diff between the M3 and the older ARM7? Edit: This seems more recent. http://www.electroni...o-community.htm Ta Les

Hi, No, it's not for another nixie clock... but I was wondering about connecting an N+ to a 74141 nixie driver. The datasheet says Vih > 2V Vil < 0V so I'm guessing that the 3.3V I/O pins will work fine? Ta Les

Hi, I've been playing with N+ at home plugged into my ADSL router/modem (Billion 7800G) and it works just fine. However, today I took the board into work and had a strange issue when connected to our network. Plugging the N+ into our network - which I believe is some flavour of a cisco gigabit switch - causes the network adapter on the N+ to appear to continually reset. By this I mean the three n/w leds turn on, one blinks a few times then all three turn off for a couple of seconds. This repeats. Originally I was using HttpWebRequest to retrieve some data from a webserver on my PC. This code wass hanging on the GetResponse call. After simplifying the code, I've ended up with a main that only calls Thread.sleep in a loop. The network still appears to reset endlessly. I'm using a static IP and firmware 4.2. Curiously, about 1 in 100 resets, the board functions fine and I can ping it and make socket connections back to the server running on my PC. But for the other 99 times, the board is not pingable. I've brought the board home again tonight, changed the static IP to one on my network and the board works fine. So I'm wondering is it something to do with the networking hardware at work? Thanks
