Suite-16 The inspiration for this project was to design a 16-bit TTL computer loosely based on Steve Wozniak's 16-bit virtual cpu "Sweet-16". It written in 6502 assembly language to augment the Apple II when performing 16-bit operations. Sweet-16...
I must confess I haven't spent much time looking at NTC curves before. My prior knowledge was that they are somewhat ill-defined and can only deliver reliable measurements when calibrated individually. source: https://support.belimo.us/Documentation/Standards-Compliance/957165601/What-is-the-difference-between-NTC-10K-Type-2-and-Type-3-sensors.htm...

Reading this Japanese article on a kit sold in Japan to build a Z80-MCB, I realized the presence of a possible bug seeing this two images: As you can see, there is a Z80-MCB without any Virtual Disk or RTC attached and in the resulting screenshot the...
The unusual geometry of plotbot means that one has to find a way to map the Cartesian coordinates of what shall be drawn to the coordinates of the steppers in a way that the tip of the triangle that is formed by the arms will follow the Cartesian coordinates...
I also wanted to sniff the communication between the micro controller and radio IC, but couldn't get the case of the remote control open. At the next opportunity I brought the Mi-Light Wi-Fi controller with me and got that open more or less easily:Inside...
As you can see airodump-ng picked up the WiFi of the drone and also that it is running on channel 2. Next I recorded some packages. sudo airodump-ng -w JJRC_out -c 2 -bssid 10:A4:BE:2E:77:B5 wlan0mon While recording I simply used all the functions the...
Hardware ESP-32: The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESP32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes fully-equipped...
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...
Remapping the KeyboardGiven most of the work is done with the "basic shift logic" how hard could it be?The basic shift logic:Well much harder than expected, here is the schematic:Now many will recognise this as a PLA (Programmable Logic Array).Designing...
Any enclosure needs to be easy to access yet provide enough space to get all of our cables in and out without being too big. A tough challenge!---------- more ----------Once our technology solution is chosen, we have to mount it, cable it, make it all...
Native C compiler (smaller C) with Color text TV system. Under a tiny memory, libraries are hard to link, so library such print, filesystem is on the flash and call from function-table. PS/2 keyboard(US, Japanese) can be used. Library for Color Video...
