Maker’s Rule-The Feature Packed PCB Multi-Tool

It has been a while since i posted my Tinker Rule which i made during college days. I received a few requests for the ready to etch pdf which helped me gauge if this seemed to be useful to people. The response was somewhat positive and so, i decided to put in some extra effort and make it handy, portable and manufacturable ! My initial scale was big and not handy, So, this one should be small and compact an ...

Building a low cost wifi camera

Update! Here is a post with the BOM for the project. Sometime ago I came across the Arducam Mini which is quite a nice camera module from UCTronics. It is a small PCB with a two megapixel OmniVision OV2640 sensor, an interchangeable lens and an FPGA to do the heavy lifting of image processing and JPEG encoding. Priced at around 24 Euros (lens included) you can easily buy a few without hurting your wallet an ...

Bionic eye returns sight to the blind

What if you could cure blindness as easily as turning on the lights? That’s what one doctor and his team are hoping to achieve with a clinical trial that uses a new form of retina implant to return sight to patients who have  lost the ability to see. And for one of the six patients, it’s been a pretty incredible journey. Rhian Lewis was just a toddler when her parents noticed she had trouble seeing in the d ...
