The Twittering-plant Botanicalls project has undergone a revamp, with very nice new kits. These are still Arduino-based but are now pared down to a single green-leafed PCB. The best part of the new design is that the XPort modules and microcontrollers are preprogrammed with the code for a unique Twitter account. That means you can just plug it in and its ready to go, a lot easier than the last rev which required a bit of hacking to work. The kits are also priced 1/3 less. Its cool to see the project get better & better…so I snagged a couple and they’re in the Adafruit shop now!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

It would be really cool if such kit used bluetooth or other wireless module, so it won’t require to wire all the plants around the house. 🙂
The original version did! But it was much too expensive for a DIY kit. Plus lots of geeks can use this in the office 🙂
why are all the wireless kits so expensive? Both Bluetooth and ZigBee costs under $3 , Atmel has quite cheap IEEE 802.15.4 radios now. Is it possible to build something like Arduino, but under $10  and with ZigBee radio included? For wireless sensor network prototyping board?
 Ideally, it would cost under $1 because one needs a lot of them. I understand we are not there yet. But why not? Because no one wants millions of motes?
it costs $3 if you’re building 100,000. xbee modules go for about $20/ea on the retail market. if you need two that means the kit would cost $100 more after all the markups!
