1 Intro The Enecsys Gateway is a Zigbee gateway allowing communications between the Enecsys microinverters and their monitoring backend. The Enecsys company is unfortunately defunct since 2015 and their DNS domains have been taken over by a UK enecsys...

After the explorations with #YGREC-РЭС15-bis, I reached several limits and I decided to scale it down as much as possible. And this one will be implemented both with relays and VHDL, since the YGREC8 is a great replacement for Microchip's PICs....
In this project, we will build a 2.4GHz Wlan scanner using the nRF24L01 radio board. In this project, the output delivers all the interference and information in the scanned area in the form of ASCII codes. In the project of making this scanner,...
This idea was born when i saw this project years ago: https://hackaday.io/project/170961-resistor-color-code-clock-v10 NOTE: There is a bug showing resistor values under 100 since gold nor silver can be displayed. AND the multiplier seems to be...
Today we present the FlameWheel Robot assembly tutorial and quick-start guide! It is rather difficult to assemble this robot without guidance. Feel free to refer to my introductory tutorial today.Flamewheel (A 2WD Remote Control Robot) is part of our...
The story so far... Update: Row scanning working.Known/working: Building and loading via JTAG new firmware into the main FPGA. This firmware is starting from scratch, we don't understand much yet about the default Barco firmware, although we've dumped...
KeypadAdding a 12 key keypad (0 to 9 with * and #) requires seven i/o pins. Each switch connects one row wire to one column wire. Connection scheme used in the test code is shown below. 300 ohm resistors protect the outputs from short circuits when multiple...
As usual, the problem isn't a new problem, and this isn't a new solution. But I will describe it to help someone doing the same. With this project I've made a wifi infra-red remote control for my Daikin air conditioner. In these schema you can see...
SolidCore CoreXY CAD Design In Fusion 360 All Metal Parts Our long term goal is to is to build a modular platform, not just a printer. Think of it as an ecosystem of parts that can be arranged in different configurations and adapted for unique applications....
I did a quick test with a laptop(Putty) and Arduino in the vehicle and was able to to get OBD info, so I guess the connections are fine. And the 1996 Ram even started afterwards. I added some new handling for 'SEARCHING...' after this. Looks like there's...
One Bit CPUs There are a couple of one bit CPUs on the Internet. I have start with the MC14500B chip. This chip was used many years ago for PLCs but the documentation is still available: http://tinymicros.com/mediawiki/images/e/ec/MC14500B_Handbook.pdf...
From OpenCores PDP-8 page: Features In this FPGA implementation, the PDP-8 CPU can be configured to emulate the instruction execution of a PDP-8 (Straight-8), PDP-8/S, PDP-8/S, PDP-8/I, PDP-8/L, PDP-8/E/F/M, PDP-8/A, HD-6100, or a HD-6120. The...
The open communication robot for everyone In recent years, a variety of communication robots have appeared on the market. However, most of them are "closed", dependent on specific proprietary services, or their specifications are not disclosed...
