AquaPing is an open-source, battery powered acoustic water leak detector module (Crowdfunding)

The AquaPing is an open-source hardware, ultra-low power acoustic water leak detector sensor based on Texas Instruments MSP430 microcontroller and a microphone that can detect leaks without having to do any plumbing, instead capturing audio for water leak detection, and it even works for leaks behind walls. All signal processing and analysis occur on the MSP430 MCU, so no audio is streamed to the cloud and eavesdropping is impossible, plus the sensor only captures high frequencies out of the range of normal conversations, so eavesdropping is not feasible, plus those higher frequencies are also said to provide highest sensitivity and reliability. AquaPing specifications: MCU – Texas Instruments MSP430FR5994 microcontroller to perform FFT spectral analysis (10x faster/efficient than ARM-Cortex M0+) Audio capture – MEMS microphone covered by a small rectangular plastic structure to form a Helmholtz resonator. Minimum detectable leak rate – 0.01 gpm (gallon per minute) depending on stand-off distance […]

Pixel Pump is an open-source, manual pick-and-place machine (Crowdfunding)

Pixel Pump is an open-source hardware vacuum pump that should be easier to use than a pair of tweezers to pick and place SMT components, and suitable for prototypes and small production runs. The system comes with a pen with five exchangeable stainless-steel nozzles to match the size of components, a foot pedal, and several tactile silicone buttons with RGB backlighting to control the unit. The button on the unit (customized parts bought from Alibaba) allows you to change operation modes, switch between high- and low-power settings, or activate reverse mode to clean your nozzle. It’s also possible to configure vacuum power and LED brightness with the buttons. The foot pedal is used to control the vacuum pump to pick up and release the components. A serviceable air filter is also integrated into the design to protect the vacuum pump and valves from debris. Robin Reiter, Pixel Pump’s designer, explains […]

ShaRPiKeebo handheld Linux computer based on Raspberry Pi Zero (2) W ships with a LoRa radio (Crowdfunding)

Raspberry Pi Zero portable Linux computer with LoRa

Morpheans ShaRPiKeebo is a portable Linux computer based on Raspberry Pi Zero W or Zero 2 W SBC that reminds me of the Allwinner R8 powered PocketCHIP handheld computer that was introduced in 2016, and was quite popular (for a niche product) at the time. The ShaRPiKeebo comes with a physical QWERTY keyboard, a daylight-readable screen, and Wi-Fi & Bluetooth connectivity, but also adds a 433 MHz LoRa radio that should make it usable as an off-the-grid communicator. Just like PocketCHIP, the ShaRPiKeebo can be used for system administration, retro-gaming, pen testing, STEM education, and all sort of maker projects. ShaRPiKeebo specifications: Supported SBCs via 40-pin GPIO header – Raspberry Pi Zero W, Raspberry Pi Zero 2 W, and (maybe) compatible SBCs like Radxa Zero or Banana Pi M2 Zero Display – 2.7- inch SHARP memory display (LS027B7DH01) with 400×240 resolution, low-latency, low-power Connectivity 802.11 b/g/n WiFi 4, Bluetooth 4.2 […]

802.11ah WiFi HaLow development board launched for $99 (Crowdfunding)

When 802.11.ah WiFi operating in the 900 MHz frequency range for low-power long-range communication was announced in 2014, then named WiFi HaLow in 2016, I naively assumed it would soon compete against other LPWAN standards like LoRaWAN or Sigfox. However, over the next few years, we did not see much interest in the wireless standard. But it may be picking up now, as Gateworks recently announced a Newracom NRC7292 based 802.11ah WiFi HaLow Mini PCIe module for their Arm Linux SBC’s, and a company called TELEDATICS has now introduced the Halo TD-XPAH 802.11ah Hallow development board featuring an AzureWave AW-HM482 module. Halo TD-XPAH board specifications: 802.11ah WiFi HaLow connectivity AzureWave AW-HM482 module based on Newracom NRC7292 Cortex-M3/M0 SoC with 752KB RAM, 2MB flash Compliant with IEEE 802.11ah WiFi HaLow operating in 902.0 ~ 928.0 MHz range Up to 15 Mbps data rate Up to at least 1km range, but can […]
