Philips Hue Bridge POE

IOT, Smart Home, Intelligent home; Meaning a lot of connected devices (and power adapters & cables!)
I have been using the Philips Hue system from the very beginning, recently upgraded to the Philips Hue Bridge 2.1 Square-shape bridge (supports Apple HomeKit)

After my last upgrade to the home infrastructure. with the new and improved UniFi Switch PRO 24 PoE I wanted to get the most out of the switch with POE (Power-Over-Ethernet)

I would have loved to see the Philips Hue Bridge with build-in POE, but unfortunately that was not the case of the 2.1 release. Luckily with a bit of creativeness this can be achieved with the correct equipment and cables.

The bridge comes with a regular DC barrel plug adapter

Parts list for the items you will need:

Barrel adapter to USB – NOTE: The V2 bridge barrel is 5.5 x 2.5 mm
Direct link: 5.5 x 2.5 mm DC USB
Moreover, if you buy a barrel adapter to USB, you will be able to use any POE adapter.
Ubiquiti Instant 802.3AF to USB adaptor requires not configuration plug and play!

NOTE: 2 Networking cables will be needed with this solution, 1 for POE, and 1 for the actual device connection.
Additionally, if you do not want to use 2 ports, go for a POE splitter with barrel adapters (802.3af POE splitter with 5 volts DC) 802.3af PoE Splitter with 5 Volts DC Plug | PLUSPOE Power Over  Ethernet for 5v Devices Like Foscam, Amcrest, Dropcam and More, 3.5x1.35mm DC  Barrel: Kindle Store

Delete default material in Ultimaker Cura

Would you like to delete the default material profiles in Cura? Look no further!

For some reason Ultimaker does not support the removal of default materials, but it can simple be done by remove the files xml files associated with each profile.

On Windows go to c:\Program Files\<your version of Cura)\resources\materials
Delete all the files, this will remove all default material profiles.

If you have already created custom profiles, don’t worry, that are kept else where. (eks: c:\Users\<username>\AppData\Roaming\cura\<version>\materials\)

Anet A8 Plus upgrade to Marlin 2.0.x

I really wanted to upgrade my Anet A8 Plus with a bed leveling sensor, unfortunately I was not able to find the source code for the firmware stock firmware used.

UPDATED: Some is now available here: ANET 3D Firmware

  1. Download and install the latest Arduino IDE
    1. NOTE: I used 1.8.10, You can always download an older version, if needed.
  2. Download the Anet A8 board definition
  3. Extract the Anet A8 board definition
  4. From the extracted Anet A8 board definition copy the Arduino\Hardware folder to the Arduino installed location (Default: C:\Program Files (x86)\Arduino)
  5. Download the latest Marlin 2.x.x firmware
  6. Extract the Marlin firmware
  7. From the extracted Marlin firmware copy \Config\Examples\Anet\A8plus to the \Marlin\ folder (same location as Marlin.ino)
  8. Connect USB to your Anet motherboard
  9. Open the installed Arduino IDE
  10. Download and Install u8glib by oliver
    1. Click Sketch -> Include Library, Click Manage libraries
    2. Search U8glib – MAKE SURE TO SELECT TO CORRECT ONE! – U8Glib by oliver,
    3. Click Install
    4. Click Close
  11. Click Tools -> Board, Select Anet 1.0 (Optiboot)
    1. NOTE: Small and Fast Bootloader for Arduino and other Atmel AVR chips
  12. Click Port, Select the assigned COM port
    1. NOTE: If you want to check if your connected, Click Tools -> Get Board info. This will return information about the board, if your connected.
  13. Find the line in the Configuration.h: #define ANET_FULL_GRAPHICS_LCD
  14. comment it out like this: //#define ANET_FULL_GRAPHICS_LCD
  15. Find the line: //#define CR10_STOCKDISPLAY
  16. Uncomment it like this: #define CR10_STOCKDISPLAY
  17. Find the line: #define ENDSTOP_INTERRUPTS_FEATURE
  18. comment like this: //#define ENDSTOP_INTERRUPTS_FEATURE
    1. NOTE: The update and consolidation of TMC support into the TMCStepper the library has made the ENDSTOP_INTERRUPTS feature incompatible with TMC drivers, until a workaround can be found.
  19. Now you’re ready to upload the firmware, or add/remove features needed

The Anet V.1.7 board comes with a limited flash ROM (128k – 131,072 and thats including the bootloader). This will not all you to pick all features and add them.

Should you by accident (like me) put a too large firmware or corrupt the bootloader, you will need a USBasp and a 10-to-6 poled adapter.

If You see the following error, flash the bootloader using USBAsp, your sketch is properly too big.
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x60

I recommend you to review and edit you own configuration files, but for sample purposes here are mine: [download id=”931″]
