I made an adapter board so i can use different CC2500 modules without having to change the boards.
Drop a line in the comments if you want one.
It seems a firmware update for the Hue bridge and Hue bridge 2 has removed compatibility to 3rd party lamps, that version of the firmware will only work with “Friends of Hue” lamps and no longer support generic Zigbee Light Link lamps.
There was a lot of backlash on this as it can make existing, working, setups useless and raised questions about Philips still effectively being a member of the TCLA and if Hue bridges are still Zigbee complaint ?
One sore point seems to remain : Apple HomeKit certification apparently not only applies to the Hue bridge but also to the lamps connected to the Hue Bridge :
Before the 1.11 software update, a bug in the Philips Hue system allowed some non-Apple HomeKit certified lights to work with Apple HomeKit. Our 1.11 software update removed the bug with the result that non-Apple HomeKit certified lights no longer work with Apple HomeKit. This remains the case.
The discovery and confirmation of the update that removed support :

A while ago i made a popular post about having cheap PCB’s made. Some things have changed so it’s time for a new post.
BatchPCB is now OSH Park.
EuroCircuits have broadened their range of services to better cater to prototype runs and hobbyists.
Seeedstudio have a PCB prototype service.
Where there are lots of suppliers and customers shopping for the best price, sooner or later someone is going to set up a price comparison site like : PCBShopper.
The first batch was a new run of the LivingColors Arduino shield.
The second batch was a breakout board for the NiceRF SX1276 LoRa module. Here i experimented a little with contour routing.
The third batch was an adapter board to use no-name CC2500 modules in boards designed for the Quasar QFM-TRX1-24G. The boards are small (about 20 mm x 25 mm) and the minimal size for dirtypcbs PCB’s is 100 mm x 100 mm. Here I experimented with breakout panels, putting 4 PCB’s in one design.
The end result worked out nicely, two things I’d do better now are :
One of my customers has found a much simpler solution : adjust the power settings in the CC2500 configuration.
In the file LivingColors.cpp
The lines :
// write power setting to PATABLE memory using single access write. See table 31 on page 47
// of datasheet
De value 0xA9 can be changed to 0xBB (-2 dB output power), 0xFE (0 dB output power) or 0xFF (+1 dB output power)
The registers of the CC2500 are described in the datasheet page 47, table 31.
The updated library can be found here : LivingColors.zip
Among the stuff i bought is :
SKU: 382445 Quad band GPRS module. Haven’t played with this yet. There is no documentation on the DX page. Seeed has some general info about the module and the Seeed module that may be helpfull. The Adafruit FONA shield uses this module as well.The last picture in the DX page can be used to figure out the pin-out. One thing I did notice is that the board is not going to fit on a breadboard nicely.
SKU:4711. Solder Paste (sold out). The name “Solder Paste” is a source of great confusion. This type is basically solder (so lead-tin-silver-whatever) in paste form. “Solder Paste” can also be flux to improve soldering and is a resin. Both are sold in very very similar looking jars described very poorly on DX.
SKU:19866 Stainless Steel Precision Angled Tweezers. These are by far my favorite tweezers for precision work. They fit nicely when closed and because they are in a 90 degree are great fro placing SMD parts.
SKU: 56648457 Anti-Static Static Charge Release Wrist Band (1.6M Grounding Cable). If you are working on repairing electronic equipment it’s smart to take precautions against static electricity. I have a mat as well and all the electric / electronic tools are grounded.
SKU: 268720 NILLKIN Protective Flip Open Case w/ Stand for Google Nexus 7 II – Black. The Nexus falls sometimes, coffee gets spilled, accidents happen. Then it is nice to have a case. The fake leather on the inside gets dirty. And i have no idea what “There is no end in pursuing.” means that is written on the inside.
SKU: 288552 Key Shaped Phillips Screwdriver + Slotted Screwdriver Set. Two screwdrivers to attach to your keychain.
SKU: 142041 FTDI Breakout board. Most embedded / hobby stuff either has a USB serial serial on board (teensy, arduino etc.) or has a logic level serial interface. This FTDI breakout board provides you with a USB serial interface. Specs are thin, as usual on DX, but the board seems to use the “standard” pinout that Adafruit, FTDI, Sparkfun and JeeLabs use.
The price difference is pretty huge compared to the (about 6 USD vs 15 USD). I wonder if the FTDI chips on this board are the real deal. Also, it’s unclear how the board can be modified from 5 V. to 3.3V.
SKU: 223501 A Female to micro USB male. I have a couple of these to connect USB devices to a Nexus 7 via USB OTG. Nexus Media Importer will mount this external storage just fine. Great for watching movies while traveling or viewing the images on the camera.
SKU: 56648457 Power plug converter. Many power supplies (safe ones from a proper brand) can work from 110 to 230 V AC. It’s just that they have the wrong plug. I prefer not to but you can use one of these plug converters to plug a US cable or adapter in a European socket. Check the maximum and minimum input voltages of the device you will connect.
