    If you go to that same link there should be two .jpg files with the wiring. One thing to make sure on any of the Adafruit boards running CircuityPython you want to make sure you have the Libraries copied onto the drive. There is single Lib folder that needs to be copied and pasted. More details on that are here. https://learn.adafruit.com/welcome-to-circuitpytho...

    There was a note in the instructions mentioning that sound was not yet implemented in the code just yet. Hopefully soon in the future.

    One other thing to note on the Neopixel Ring, You can daisy chain them, so DO = Digital Out and DI - Digital In.

    I just wanted to mention if you have subscribed to earlier hackerboxes, Box #25 I know and one other one had these battery holders in them so if you had those boxes you might have left over parts possibly. :)

    I hooked up the fingerprint reader today. Super cool! Very easy to use and will work well in any access control project or anything where you need to track identity. I solder the pins on the up side of the nano board and 3d printed a holder. I need to tweak a bit.

    I threw together a 3D stand/bracket for mounting the LED matrix. It's not perfect but it works. Feel free to download it here and alter the design to suit your needs.https://1drv.ms/u/s!AlJEBzxLFQ7zmeohfQnjctBeNV9n7w

    Do you have the PxMatrix Library library installed? That could be it and it is sometimes neccessary to restart the Arduino IDE after adding libraries even though it doesnt tell you too.

    So I upgraded my pool thermometer that I made using the Arduino Nano and OLED from box # 35. Works great and much easier to see!

    These board you sometimes have to press the BOOT button right when it begins the download after compiling. Sometimes it takes several tries to get the timing down. This puts the board in programming mode.

    Oddly enough I had the same problem on my desktop PC but not on my laptop. I upgraded both to the latest IDE but still had the same problem. Strange....

    Here are a few pics... One with the text color inverted. It's harder to read.

    If you are playing around with the MQ-3 Sensor I would highly recommend reading about the characteristics. https://jenslabs.com/2013/03/18/measured-sensor-ch...I have found the times for it to reset/stabalize to be somewhat accurate. I am going to get a TGS822 and try the Ketone sensing project with it.

    Did you first install the SSD1306 Library and if so, how did you go about installing it? Sometimes you need to restart the IDE after installing libraries.

    Great box this month! Ironically I was thinking I needed to put a little kit like this together. Working in IT I am often times wearing the network engineer hat and this is the perfect compliment to Wireshark. Got the OpenWRT loaded. I wonder if DD-WRT will work on it? I have loaded that on many routers and just explodes the features and capabilites of a cheap router. More like what you would pay hundreds of dollas for.

I have a few feet of solder wrapped in the spool of solder wick. Screwdrivers, small cutters and needle nose, pry tool, zip ties, USB cable and wall-wart as well as a USB power meter and 8GB flash drive.

    I'm half way through building the Enigma Machine. Just have to get the keypad on and tweak a few things.

    Which OS are you running? If you are using Windows you want to make sure that ST-LINK shows up in the Device Manager. It will be under Universal Serial Bus Devices. Also, try to avoid using a USB extension cable if possible. It's always a good idea to load the latest version of the Arduino IDE. In some cases I have had issues and simply restarting the IDE wasn't good enough. It required a reboot of the computer too.

    After installing I unplugged from the USB and rebooted. Plugged back in USB and the com port appeared.

    Maybe try using jumper wired or a stacking header if you have one to connect the SD module to the breadboard. I was having issues and that was the fix. See my previous post about it with a few pics.

    If you have issues with your SD card module try using male/female jumper wires to connect it or a stacking header if you happen to have one. I was having issues with mine and discovered that it wasn't making a good connection on the breadboard. So functionality was hit and miss. After using a stacking header to connect it, it works like a charm every time. The hearder pins on the SD module are a tad short for plugging into a breadboard directly.

    I plugged in the GPS module and Windows 10 has a USB driver for it so it did not show up as a COM port. So I installed the Ublox U-Center and selected the Ublox driver instead of the Windows driver and now have it showing up with a COM port. So now it reads in the Arduino monitor. Works fine in U-Center too. Just can do both at once. Just sharing in case anyone else runs into this.

    On a side note - The ruler was worth the cost of the box alone! It's bad to the bone! :)

Then I ate a Nutty Bar and checked it again! AT command responds "OK"But - AT+CREG? = 0. I assume that's meaning its not connected. The Hologram Dashboard doesn't show any data either.

    Thanks Slackmaster! That helps a lot.

    ACC is typically used in the automotive industry and I think means ACCessory circuit. When you insert key into ignition switch and turn it to the left (backwards) you are turning on the ACC circuit. It will allow you to operate radio, windows and other accessories, but it does not turn on fuel pump and other engine controls. It saves battery for when you need to operate vehicle components without engine being on.

    Jasper,You were close. I figured I must have had it backwards but I double checked several times and I had it correct. After closer examination I discovered the chip was on backwards. Actually the whole socket was soldered on the board backwards. The chip was in the socket the correct way. I turned it around and was good to go. Then I discovered the cr2031 battery was dead. I put in a new one and I am in business! Thanks for tip to get me going!
