Hackaday Prize Entry: Smart USB Hub And IoT Power Meter

by Moritz Walter August 02, 2016

[Aleksejs Mirnijs] needed a tool to accurately measure the power consumption of his Raspberry Pi and Arduino projects, which is an important parameter for dimensioning adequate power supplies and battery packs. Since most SBC projects require a USB hub anyway, he designed a smart, WiFi-enabled 4-port USB hub that is also a power meter – his entry for this year’s Hackaday Prize.

[Aleksejs’s] design is based on the FE1.1s 4-port USB 2.0 hub controller, with two additional ports for charging. Each port features an LT6106 current sensor and a power MOSFET to individually switch devices on and off as required. …read more

Your Laundry Is Done!

by Jenny List August 01, 2016

Have you ever put a load of dirty clothing in the washing machine and set the cycle running, only to forget all about it and discover a mouldering congealed mass in the machine a few days later? [Xose Pérez] has more than once, and to stop it happening again he’s got a project that monitors the machine in his basement and notifies him when his wash is done.

At the centre of his washing machine monitor is an ITead Sonoff IoT mains on-off switch. This device contains a 10A mains relay, an ESP8266 chip to control it, and a small …read more

ESP8266 MicroPython Contest Gives You the Excuse You Need

by Elliot Williams July 29, 2016

As if the prospect of having everyone’s favorite scripting language ported over weren’t enough to get you to install MicroPython on a spare ESP8266, there is now a contest for that. Over on Hackaday.io the MicroPython on ESP8266 contest is under way and you’ve only got until the end of August to submit your creation.

The prizes? First place gets an OpenMV camera board because [Radomir], who’s running the contest, has an extra one. OK, it’s not as lush as the corporate-sponsored goody-bag that we’ve got running in the Hackaday Prize, but there’s no reason that you can’t enter both. …read more

New Chip Alert: RTL8710, A Cheaper ESP8266 Competitor

by Brian Benchoff July 28, 2016

Almost exactly two years ago, shocking news thundered across the electronics blogosphere. There was a new WiFi module on the block. It was called the ESP8266, a simple serial device capable of taking care of an 802.11 network and a WiFi stack, giving any project with a microcontroller access to the Internet. Earlier modules to connect microcontrollers were sufficient for the task, but nothing could beat the ESP8266 on price.

Now, there’s a new module that’s even cheaper and more powerful than the ESP8266, and just like all of our favorite parts from China, it inexplicably shows up on eBay …read more

Ask Hackaday: Is The ESP8266 5V Tolerant?

by Brian Benchoff July 28, 2016

The ESP8266 is the reigning WiFi wonderchip, quickly securing its reputation as the go-to platform for an entire ecosystem of wireless devices. There’s nothing that beats the ESP8266 on a capability vs. price comparison, and this tiny chip is even finding its way into commercial products. It’s also a fantastic device for the hardware tinkerer, leading to thousands of homebrew projects revolving around this tiny magical device.

In every technical document, summary, and description of the ESP8266, the ESP8266 is said to be a 3.3V part. While we’re well into the age of 3.3V logic, there are still an incredible …read more
