Continuing from my previous blog post about Hi-Link HLK-RM04 module, I have finally received the ESP8266 Serial-to-WiFi module that I’ve been waiting for. As I said previously, with the popularity of IoT devices, there is an increasing demand for low-cost and easy-to-use WiFi modules. ESP8266 is a new player in this field: it’s tiny (25mm

I’m starting to source parts for my nixie tube experiments. I’m in the very early stages of prototyping a nixie clock. My Breakout Boards were a bust, but that’s not stopping me from pushing on with the nixie-tinkering. When it comes to resistors, it’s so much cheaper to buy in bulk. It’ll take me a

Arduino and Raspberry Pi are great, well-utilized DIY boards for hacking just about anything you want to design. But if you’re looking for an alternate hacker board, here are seven that Steve Nelson, Freescale’s director of ecosystem and marketing programs, presented at this week’s Designers of Things (DoT) conference. With some starting below the $20

The ADA4096-2 dual and ADA4096-4 quad operational amplifiers feature micropower operation and rail-to-rail input and output ranges. The extremely low power requirements and guaranteed operation from 3 V to 30 V make these amplifiers perfectly suited to monitor battery usage and to control battery charging. Their dynamic performance, including 27 nV/√Hz voltage noise density, recommends
