Few days are worse than a day when you hear the words, “I’m sorry, you have cancer.” Fear of the unknown, fear of pain, and fear of death all attend the moment when you learn the news, and nothing can prepare you for the shock of learning that your body has betrayed you. It can be difficult to know there’s something growing inside you that shouldn’t be there, and the urge to get it out can be overwhelming.
Sometimes there are surgical options, other times not. But eradicating the tumor is not always the job of a surgeon. Up to 60% of cancer patients will be candidates for some sort of radiation therapy, often in concert with surgery and chemotherapy. Radiation therapy can be confusing to some people — after all, doesn’t radiation cause cancer? But modern radiation therapy is a remarkably precise process that can selectively kill tumor cells while leaving normal tissue unharmed, and the machines we’ve built to accomplish the job are fascinating tools that combine biology and engineering to help people deal with a dreaded diagnosis.

A few months ago the Raspberry Pi magazine The MagPi gave away a piece of hardware, the Google AIY voice control kit. Subscribers all received one, but as always the eBay scalpers cleaned up all the in-store copies and very few lucky enthusiasts scored a kit of their own.
Among these frustrated Pi owners was [Circuitbeard], who decided instead to make his own kit. And since a cardboard case lacked style, he decided to do so in the shell of a 1980s Tomy Mr. Money toy novelty bank. Into it went a Raspberry Pi Zero W and an audio pHat, with a servo to operate the head and a microswitch connected to the toy’s arm as a trigger.
The Python code to run everything is all included in the write-up, and he’s posted a video of the device in operation which we’ve placed below the break.

A good video game prop can really spruce up the decor — doubly so if it’s a glowing, futuristic potted plant transplanted(sorry!) straight from Deus Ex: Human Revolution.
Since it’s a bit difficult to grow neon light vines, this project is more lamp than plant. The maker with the green thumb is [Phil], from [JumperOneTV], and he is using five meters of warm white strip LEDs cut to varying vine lengths. He’s also procured a store-bought flower pot that conveniently mirrors the in-game model. The vines are made of 16mm polyethylene tubing which he’s shaped using a heat gun — setting their shape by pumping water through it — and secured in the pot with insulation foam. Feeding the LED strips through and wiring them in parallel was simple compared to his next conundrum: supplying the power.
