Microchip SAMA5 based Giant Board Launched on Crowd Supply for $50 and Up

Giant board

Earlier this year we gave you details about some new development board, most especially about the Giant board. A tiny single board computer that runs Linux on Arm Cortex-A5 processor.  This super tiny single-board computer (SBC) is based on the Adafruit Feather form factor. Unlike its name, the giant board is actually a small microchip. And it packs an awful lot of power for its size. The news is that it has launched on Crowd Supply for $50 and up. In addition, the giant board implements the power of size, which makes it unique. It squeezes SBC into a package the size of a microcontroller board. This will in turn relax memory, storage, and processing constraints. Consequently allowing you to effectively work on your projects. Another thing to know about the Giant Board is that it runs full Debian Linux.  Giving developers and users access to an endless number of applications and libraries for their projects. Also, it supports the …

REFLO Air is a $200 Open Source Hardware Portable PCB Reflow Machine (Crowdfunding)

PCB Reflow Phone Magnifier

While possible, it can be challenging to solder SMD components with a soldering iron or a heat gun, and going with a reflow oven is much easier and normally yields better results. But reflow ovens are usually fairly bulky, and somewhat expensive. MagixBox’ REFLO Air PCB reflow machine is much more compact making it more portable, open source hardware, and affordably priced since the early bird pledge starts at $199 on Crowd Supply. REFLO Air specifications: Control panel with LCD segment display and buttons Heat Control 100-300°C temperature control K-type thermometer Cooling fan Power Supply-110V-220VAC Max Power – 200 Watts Dimensions – 138 x 138 x 51 mm Weight – 900 g The company also offers optional accessories for its PCB reflow machine with a 3D-printed phone holder to use the phone’s camera to magnify the reflow area, a mini vice made of aluminum, and a semi-automated XY table. The documentation and resources have not been made public right now, …

Split Home Energy Meter Combines ESP32 with Microchip ATM90E32 IC (Crowdfunding)

Split Home Energy Meter

It’s always useful to monitor the electricity consumption of your house, as you can easily and quickly find out whether an appliance is suddenly consuming a large amount of electricity before finding out from your next utility bill. It can also help remotely monitoring if an appliance has stopped working and fix it as soon as possible, for example an electric pipe heater making sure your pipe do not freeze in a holiday home. In many cases, a qualified electrician needs to be involved for the installation of whole home energy meters both for safety and insurance matters. We’ve seen in the past energy meters fit easily into a circuit breaker box but they may not be suitable for all setups. I’ve previously reviewed an inexpensive digital clamp meter that you just need to clip on one of the wire connected to your home without having to mess with dangerous voltage and current, nor worrying about UL or TUV certifications. …
