Review of ITEAD Studio IP66 Waterproof Case for Sonoff Wireless Switches (and Other Boards)

ITEAD Studio recently launched a waterproof enclosure for $2.90 (now at still a decent $3.90), rated IP66, for their family of Sonoff wireless switches, so you can safely use them outdoors protected from rain and dust. The company sent me one sample together with Sonoff RF switch supporting WiFi and 433MHz RF connectivity so that I can test the case, and write a review describing my experience. I’ll focus on the waterproof since this is the main focus of this review, and beside Sonoff RF, you can also use Sonoff basic, various other Sonoff boards (POW, TH10/T16), and even other development boards as we’ll seen below. I’ll be using the stock firmware with eWelink app, but if you prefer alternative firmware like ESPurna or Sonoff-Tasmota, you may want to flash it to your Sonoff now. The waterproog case has two parts, a rubber cord, two waterproof PG7 connectors, and four […]

Octo SPI / HyperBus Interface is Designed for High Speed Serial Flash, RAM, and MCP

So far, if you needed high speed storage with low pin count in your MCU based board, you could use QSPI (Quad SPI) NOR flash, but earlier this month I wrote about STM32L4+ MCU family, which added two Octo SPI interfaces. I had never heard about Octo SPI previously. Those two interfaces can be used with single, dual, quad, or octal SPI compatible serial flash or RAM, and support a frequency of up to 86 MHz for Octal SPI memories in STM32L4+ MCU. STMicro OctoSPI interface also supports Cypress/Spansion Hyperbus mode to connect to HyperFlash or HyperRAM chip, or even HyperFlash + HyperRAM Multi-Chip packages (MCP), and variable or fixed external memory latency as defined by the Hyperbus protocol specification. The latter reveals Hyperbus supports performance up to 400 MB/s (provided the controller support 200 MHz), and relies on either 11 bus signals using 3.0V I/O (Single-ended clock CK), or […]

Cheap Evil Tech – WiFi Deauther V2.0 Board and Autonomous Mini Killer Drones

Most technological advances usually improve life of people, and with the costs coming down dramatically over the years, available to more people. But technology can be used for bad, for example by governments and some hackers. Today, I’ve come across two cheap hardware devices that could be considered evil. The first one is actually pretty harmless and can be use for education, but disconnects you from your WiFi, which may bring severe physiological trauma to some people, but should not be life threatening, while the other is downright scary with cheap targeted killing machines. WiFi Deauther V2.0 board Specifications for this naughty little board: Wireless Module based on ESP8266 WiSoC USB – 1x Micro USB type changed, more stable. Expansion – 17-pin header with 1x ADC, 10x GPIOs, power pins Misc – 1x power switch, battery status LEDs Power Supply 5 to 12V via micro USB port Support for 18650 […]

Gameshell Portable Retro Gaming Console Features Clockwork Pi Allwinner R16 Board (Crowdfunding)

Allwinner R16 with its lowly four Cortex A7 cores and Mali-400MP2 GPU would not normally come to mind when designing a gaming console. But Nintendo used the R16 processor twice in their retro gaming consoles: NES Classic and SNES Classic Edition. Clockwork, a startup based in Hangzhou, China, decided they could also do gaming console with the processor: Gameshell. But their product is quite different, as it’s both a portable console with 2.7″ display, and a development platform with the console based on Clockwork Pi development board, and an Atmel AVR (Arduino) based keypad board. Gameshell specifications: Clockwork Pi development board SoC – Alwinner R16-J quad core Cortex A7 processor @ 1.2 GHz with Mali-400MP2 GPU System Memory – 512MB or 1GB (in future revision of the board) Storage – 1x micro SDHC slot Video Output / Display I/F – 18-bit RGB display interface, micro HDMI (planned in revision of […]

Detect Lightning with Those AMS AS3935 “Thunder” Boards

Launched in 2012, AMS AS3935 Franklin lightning sensor is – at its name implies – a lightning sensing IC. The chip was designed for low power, portable or fixed wire-line applications, and beside detecting electrical emissions from lightning activity, it can also provide an estimation of the distance to the head of the storm from 40km away down to 1km, while filtering out other signals from motors, microwave ovens, etc… The chip interfaces via SPI or I2C to the host processor / micro-controller, and comes in a small MLPW-16 (4x4mm) package. Price is $3.55 per unit for 1k orders. Applications include wearables, golf carts, pool safety, portable GPS, bike computers, weather stations, uninterruptible power supplies, smart grid systems, environmental monitoring systems, etc… Basically, AS3935 can be used either for weather monitoring, or safety applications. I’ve found two maker boards with the chip: MikroElectronika Thunder Click board compatible with MikroBUS socket […]

VoltaStream AMP1 Linux Audio Board Includes a Stereo Audio Amplifier, Adds WiFi and Bluetooth

Last summer I wrote about VoltaStream ZERO an audio board powered by NXP i.MX6ULL processor, with up to 1GB RAM, a Texas Instruments DAC, and leveraging Raspberry Pi Zero form factor. The board runs a custom Linux distribution called PolyOS built with the Yocto Project, and including shairport-sync, librespot, SqueezeLite, a DLNA renderer, and more. Polyvection, the company behind the project is now back with VoltaStream AMP1 audio development board, with half the board very similar to VoltStream ZERO, and the other half featuring an audio amplifier, and a wireless module for WiFi and Bluetooth. VoltaStream AMP1 board specifications: SoC – NXP i.MX6ULL ARM Cortex-A7 processor @ 996 MHz System Memory – 512 MB DDR3 Storage – micro SD card slot Audio 1x I2S for integrated DAC and AMP, 1x I2S for GPIO access, 1x TOSLINK-IN jack Analog DAC – Texas Instruments PCM1862 (SNR 103 dB) Amplifier – ISSI IS31AP2121 […]
