Easily Make DIY Battery Packs with this Building Kit for 18650 Batteries (Crowdfunding)

Vruzend-Battery-Kit-v2.0

If you have a project that requires some serious battery power, and can’t find a battery pack that matches your requirements, making your own is possible, but usually expensive as the commonly used spot welding method requires expensive tools. Vruzend has created a modular lithium-ion battery building kit that greatly ease the making of DIY battery pack using 18650 battery cells using caps, nuts and bolts. There are two versions of the kit: V1.5 kit which supports up to 3.5A continuous and 7A peak per cell, and for higher power levels, the new V2.0 kit can handle up to 20A continuous (25A peak) per cell thanks to nickel plated copper-based conductors. It makes it suitable for EV racing, high power battery banks, and other power-hungry projects. The short video below explains how the kit works. https://www.kickstarter.com/projects/1354698863/diy-li-ion-battery-building-kit-make-your-own-1865?ref=nav_search&result=project&term=diy%20battery Vruzend battery build kit is now offered on Kickstarter, and the projects has been […]

Eufy EverCam Full HD Waterproof WiFi Security Camera Works for Up to a Year on a Single Battery Charge

Wired security cameras can be troublesome to installed due to the cabling required, but luckily there are solutions to avoid all those long cables with solar powered IP cameras, or battery powered IP cameras. A few years ago I wrote about Immedia Blink WiFi HD camera that claimed to last a year on a charge, and despite several complains on Kickstarter, they seem to still be in business.  There’s now a more advanced model by Eufy – an Anker brand – that supports 1080p video recording with motion sensing and face recognition, that also lasts up to one year on a charge, and offers free storage. Eufy EverCam specifications: Resolution – 1080p Video Format – H.264 High profile Image Sensor – Sony Exmor IMX323, 1/2 9-inch Field of View (FoV) – 140° Night Vision Range – up to 10 meters Digital Pan & Zoom  – Yes, up to 8x Motion […]

Fipsy is a $10 Breadboard-Friendly FPGA Board for Education (Crowdfunding)

We’ve already seen several cheap FPGA boards in the past with the $25 miniSpartan3 (Xilinx), $34 Spartixed (Xilinx), or 40 Euros Olimex iCE40HX8K-EVB boards (Lattice), but if you have a really tight budget you can now plat with FPGA for just $10 thanks to Fipsy board. With its 256 LUTs Lattice Semi MachXO2 FPGA, you’ll be limited to what you can do for specific projects, but it could be useful to teach yourself or students FPGA programming, especially it also happens to be breadboard-friendly. Fipsy specifications: FPGA – Lattice Semiconductors MachXO2 (LCMXO2-256HC-4SG32C) FPGA @ 269 MHz max. with 256 LUTs, 2 kbit Distributed RAM, 32 LABs (Logic Array Blocks) Programmable by SPI and I2C Expansion – 2x 10-pin header supporting various interfaces including: LVCMOS 3.3/2.5/1.8/1.5/1.2  LVTTL  LVDS  Bus-LVDS  MLVDS  RSDS  LVPECL SSTL 25/18 HSTL 18 Schmitt trigger inputs, up to 0.5 V hysteresis Misc – Onboard LED Operating Supply Voltage – 3.3 […]

C.H.I.P, PocketCHIP & Voder’s Maker Next Thing Co. Is Still Up and Running (Correction)

[Update: Next Thing Co. CEO (Dave) contacted me to inform me the company was not closed, but there was just several unfortunate events: DNS problem with the site leading to the blog issue Next Thing Co Facebook page was closed months ago (due to too many requests from different sources) The Google Maps listing is not managed by Next Things Co themselves. I’ve left the rest of the post unchanged. (except the last sentence) ] Next Thing Co. introduced the $9 C.H.I.P computer powered by Allwinner A13/R8 in 2015, and worked with Free Electrons (now Bootlin) to bring mainline Linux to the platform. They also launched PocketCHIP portable Linux game console based on the module, and lateron introduced C.H.I.P Pro WiFi + BLE module based on Allwinner GR8 processor, and found in their Voder (previously Dashbot) car dashboard assistant. I’m actually still using a C.H.I.P board as a printer server, […]

SODAQ SARA is an Arduino Compatible Cellular IoT Board with LTE-M, NB-IoT, and GNSS (Crowdfunding)

There really seems to be a push for cellular IoT those days, with new hardware coming up every week.  Following up on their NB-IoT shield for Arduino last year, SODAQ has now launched two versions of SARA boards based on u-blox SARA LTE-IoT modules, and u-blox M8Q GPS/GNSS module. Both boards are Arduino compatible thanks to a Microchip SAMD21 MCU, and while u-blox SARA board follows the Arduino form factor, u-box SARA SFF is much more compact (50×25.4 mm) and potentially easier to integrate into a project or product. Another pretty unique feature (AFAICT) is that you can power the board directly with a solar panel. u-blox SARA board specifications: Wireless module (three options) with external antenna: SARA-N211 NB-IoT, band 8 and 20, for the European and African market SARA-R410M Dual mode LTE-M and NB-IoT module for all global bands SARA-R412M Triple mode module with LTE-M, NB-IoT and 2G for […]

Mycroft Mark II Smart Speaker / Voice Assistant Works with Open Source Software (Crowdfunding)

Smart speakers have gain a lot of traction over the last few years, but many of the solutions are based on Google Assistant or Amazon Alexa voice services, with both companies likely tracking your voice searches the same way they track your online searches to provide a “personalized experience” and sell you products or server ads that match your interests. If you don’t like being tracked that way, a solution is to use an open source voice assistant such as Mycroft, and install it on a Linux computer, Raspberry Pi 3 board, or Android device. The company also introduced Mark I reference hardware platform based on Raspberry Pi 2 in 2015, and while all those hardware options should be fine for the technically inclined, but not really suited to the typical end user, and AFAIK they all lack a microphone array for better hot word detection. So Mycroft has come […]
