SkinTrack Controls Your Smartwatch with Gestures on Your Skin or Clothes

A group of researchers of the Future Interface Group, Carnegie Mellon University in the US, has worked on SkinTrack technology which enables continuous touch tracking on the skin by using a ring emitting high frequency AC signal, and a sensing wristband with multiple electrodes. They’ve created sensor band and ring prototypes to demonstrate the technology. The ring includes an oscillator that generated a 80Mhz sine wave at 1.2Vpp. It consumes 7mA during operating meaning that they could get 15 hours out of the 100 mAh battery used in the prototype. The wristband features four pair of electrodes coupled with AD8302 RF/IF gain and phase comparator chips in order to derive X and Y coordinates from the phase of the signal. The sensing board produces eight analog values which are sampled by Atmel ATMega328 microcontroller’s 10-bit ADC inputs, and transmitted to the watch using a  Nordic NRF8001 Bluetooth Low Energy (BLE) […]

Electrodragon WiFi IoT Relay Includes ESP8266 Module, AC Power, and Enclosure for $6

Thanks to ESP8266, the cost of WiFi relays has dramatically come down, but so far, I could not find an all-in-one solution with ESP8266, relay, AC power and enclosure, and for example I’m still using NodeMCU board, a relay board, a USB power supply, and put all that into a plastic jar in order to control a water pump. It works but it’s not ideal, and solutions like Wemos D1 mini with relay shield improves things further, but Electrodragon has come with a connect-and-play WiFi IoT relay that integrates everything including the case for $6 + shipping. Wifi IoT Relay Board Based on ESP8266: WiFi module – ESP-12F based on Espressif ESP8266EX WiSoC Relays – 2x Songle SRD-05VDC-SL-C relays supporting 125VAC/10A, 250VAC/10A, 30VDC/10A, 28VDC/10A Input/Output – 3x terminal blocks for relay and power Expansion – 12-pin header with Rx/Tx,  GPIO4, Btn2, GPIO15, 5V/GND,  ADC, GPIO5, Btn1, OUTPUT1, and 3V3 Debugging […]

Tibbo Project System is a Modular Linux IoT Prototyping Platform based on TI Sitara Cortex A8 Processor

If you’ve found yourself needing to quickly demo a system that does not look like a mess of wire to a customer, or your project is requires low production volumes, making the cost of designing your own and mass-producing the hardware prohibitive, Tibbo Project System might be worth looking into. It features an almost bare board powered by Texas Instruments Sitara processor, and a large area for Tibbit blocks to add features as needed, as well as an enclosure. Size 3 Linux Project PCB (LTPP3) specifications: SoC – Texas Instruments Sitara AM335x Cortex A8 processor up to 1.0 GHz System Memory – 512 MB DDR3 Storage – 512 MB NAND flash, 2KB EEPROM, optional micro SD slot Connectivity – 10/100M Ethernet (RJ45), optional WiFi (via LW1000 module) and GPRS connectivity (via Tibbit #47) Expansion – 51 I/Os: 7x tiles 14x sockets for Tibbit module including 4x with UART capability up […]

MK808B Pro Android TV Stick Mini Review

MK808B PRO is the first Amlogic S905 TV stick readily available for sale, and GeekBuying sent me a sample for review. I’ve already checked out the hardware, and the lack of heatsink is a worry, so we’ll see how it performs in this mini review, where I’ll focus mainly on potential pitfalls, rather than do a throrough review as usual, since I’ve already tested so many Android TV boxes powered by Amlogic S905 processor First Boot, Settings, and First Impressions I’ve connected MINIX NEO A2 Lite air mouse RF dongle to the USB port, and Tronsmart Mars G01 wireless gamepad dongle to the mini USB port via the provided USB OTG adapter, and the provided HDMI cable to the AUX port of my AV receiver and nothing else, except the power adapter to the other mini USB port. Boot time typically takes about one minute that it’s not a speed […]

What’s the Best Android TV Box?

[Update December 26, 2017: I’ve posted a new version of this post entitled “What’s the Best Android TV Box (2017/2018 Edition)?“. I’ll leave the post below to have an historical perspective] I often get asked which TV box to buy, or what the best Android TV box is, and the answer is the TV box that fits your needs for the lowest price point possible. Considering there are around 2 millions apps for Android, they are multitudes of use cases, and you can’t provide a single answer for everybody. So I’ll provide a list of things to look for beside the processor, and three TV boxes that I think are worth considering, before providing alternatives for people who want cheaper devices. Things to Look for There are still a few things you may want to specifically look for before purchasing an Android TV box: History of regular firmware updates – […]
