  1. The orange pi zero build works pretty well with it, albeit without WiFi which is pretty garbage anyway.
  2. 8 Minutes before thermal throttling is still pretty impressive and I wouldn't think it unreasonable to need active cooling if you're going to peg all 4 cores for a long time on such a tiny board with a tiny heatsink. I'm always open for more testing though
  3. Fiddling with it more today and it doesn't take long to hit the throttle point of ~65c when compiling with -j5 and loading all cores. It might benefit from a tiny fan, I have a smallish desk fan pointed at it and it's hovering around 43c still loaded. I have been using an orangepi-zero build so that may be affecting things.
  4. You can actually squeeze a NanoPi Duo, RJ45 MagJack (LED,GND pins off), a USB port, and tiny buck converter on a half-size breadboard. Seems to be working fine with a user built stretch image for the Orange Pi Zero target, at least initially. Max current @12vDC I saw was under 400mA with sysbench and WiFi running but more tests are needed.
  5. Take your time, I was just a bit flustered and will look at it more tomorrow under better light and brain thingy. I didn't mirror the pinout, that would definitely be a possible reason and I'll give that a shot as well. e: Got it working thanks to https://learn.sparkfun.com/tutorials/mbed-starter-kit-experiment-guide/experiment-5-internet-clock It has a diagram that shows what pins go to which lines. In the end: Breakout pin 1->Nano TD+ Breakout pin 2->Nano TD- Breakout pin 7->Nano RD+ Breakout pin 8->Nano RD-
  6. Did you need to hook up all pins or cross over the RXD/TXD lines? I have the 4 RX and TX pairs hooked up 1:1 and I'm not seeing a link on my computer. It looks like I got the older version of the MagJack breakout though so it might be a bit different. Breakout P1->Nano TXP Breakout P2->Nano TXN Breakout P3->Nano RXP Breakout P6->Nano RXN Ethernet pin diagram I used here:
  7. Some quick and dirty power measurements: idle wifi connected: 160-220mA idle iperf3 client: up to 330mA iperf3 server: up to 260mA sysbench --num-threads=4 --test=cpu --cpu-max-prime=20000 run: 440mA up to 470mA sysbench and iperf3 client: 630mA idle with only 1 core active: 160mA to 180mA halt: 130mA This came up during iperf tests but didn't seem to happen again. [ 169.630039] sunxi-mmc 1c10000.mmc: data error, sending stop command e: WiFi Seems okayish but seems to top out at ~25MBit/s, pings range from 30 to 190ms with no pattern I can se
  8. Mine just hit customs and I can't wait to play with it a bit, I didn't order the mini shield though. In theory I should just be able to hook the ethernet pins up to an rj45 breakout module, right? There wasn't a schematic for the mini shield so I don't know if they do anything fancy.
  9. This looks soo tempting to pick up but I've heard bad things about the XR819 WiFi, is that going to be a dealbreaker running this in a WiFi->Ethernet bridge setup? I mean, I might still pick one up to eff around with otherwise.
  10. I'm augmenting my iBook G3 with my pcDuino3 Nano to act as a wireless gateway and host for a development toolchain. It's working fine so far and once I'm done it will be completely powered by the FireWire port The only downsides are that it is a bit big and at idle it's taking ~250mA which I'm going to have to play with at some point and see if I can get it down any more.
  11. Working on my pcduino3 nano, I'm definitely gonna be playing with this more Edit: Oddly enough I was already writing an app for a different project but you can use it to convert an image into a flat binary file you can use to send to the display. https://github.com/TaraHoleInIt/anim1b (Note: I forgot to enable dithering for this image) It's still very much WIP and is part of another project I'm working on but it can convert an image to be displayed on an oled screen using this library. Example ./anim1b -n -d input_image.png output_fla
  12. Yep, it's powered through the OTG port which also provides an RNDIS ethernet connection. It works fine it's just I want to go back to MacOS 9 which does not have an RNDIS driver so I'm looking to switch to ethernet. Totally stable, I just like fiddling with things. I brought it to Starbucks just so I could take a picture of living the hipster stereotype dream, totally worth it and the battery lasted a good 5 hours. Got lots of work done on it too
  13. Would it be safe to assume that without attaching any USB peripherals (aside from WiFi) it should be able to run from the firewire port provided I use a DC-DC converter? I would plan on hooking it directly into the 5v in header on the top and avoid the USB jack altogether. The board's main function is to provide WiFi to the ethernet connection and run devkitPro's devkitARM toolchain. In the end it'll stick onto the side of my iBook kind of like what the pi zero w does except through the ethernet jack instead of USB.

  15. I'm fiddling with a PCDuino3 Nano and the tech specs say it needs 2A to run, but my own small bit of testing shows it using much less. Is the additional current rating for worst case scenarios or additional USB devices? I made a tiny bash script to monitor /sys/power/axp_pmu/ac/amperage and /sys/power/axp_pmu/ac/voltage but I'm not seeing those figures. Idle with nothing connected except power, 1Gbps ethernet, and a 16GB SD Card: Same as above except with sysbench loading both cores: I still need to get a USB wifi adapter for this,
