Never used a Z8 MCU before, but when I found that chip "forgotten" for decades and started to read the datasheet and various documentation, I realized that it was a great MCU and wanted to see it in action... So I designed the board... Too good to rest in a box... Please note that this board * is not * for a Z80 CPU, but for a Z8 BASIC/DEBUG MCU (marked as Z8671 or Z0867108).Because this board use only a SRAM with a backup battery for data retention, you don't need any legacy EPROM programmer.The specs of the RC-Z8BASIC are:128KB SRAM with battery backup, RS-232 port, serial-USB adapter port, GPIO port, LCD (1602 or 2004) port, User led and key, on-board power supply, ROM emulation mode to enable the "Auto execution on power-up" feature, can be powered from USB or on-board power supply.All the details to build it can be found here.

Hi, I'm CRAZY PROF. Previously I have designed a communication development pcb for microchip 16f or 18f series microcontrollers.This motor driver is designed to save your pcb space.Many Arduino development shield PCBs connect to Arduino via female-male cables.I have specifically designed the Arduino uno or mega on the L298N driver card takes up less space and requires less wiring, and also re-use of all pins of the arduino was targeted.That is, 1 cable can normally be attached to the arduino pin. Additional connections to the same pin may be required if necessary. As you can see in my design, there are 2 pieces of the same arduino pin. When one pin is used, another cable can be plugged back into the same pin.Now let's move on to the features of PCB ...* It is within 10x10cm size suitable for PCBWAY campaign.* 2 layers PCB* L298N operating voltage (5v) can be taken from arduino or external supply via Jumper.* L298N can be supplied externally with 78l05 regulator up to 30v.* In most L298N pcb, current limiting resistor is not installed or short-circuited. With this in mind, I have separated the SENSE-A and SENSE-B pins and made analogue current measurement possible.* PCB in this state can drive stepper motor or dc motor. If desired, a single motor can be connected to the bridge.* L298N heatsink is reserved for the outside of the pcb.* In case of sponsorship, I will provide free transmission to the required robotics project developers or technical lab laboratories.I would also like to thank PCBWAY for giving us this opportunity ...

Hello there, I'm Crazy Professor.With the development and expansion of Arduino cards, many development cards were produced. In the meantime, the Microchip PIC series was a bit off the agenda. Because there was no development platform.I have designed a development card that contains several communication protocols. In case of sponsorship, I will donate to the relevant institutions. This card can also be used on the arduino platform.PCB Specifications:* 100x100mm double layer,* Built-in RS232 circuit,* Built-in RS485 circuit,* Built-in MCP2515 + JA1050 CAN-BUS circuit,* Built-in 74HC595 Shift Register,* 8pcs LED,* FTI series USB to TTL converter,* Usb power supply,* Easy to use with plug-in terminal,* Easy circuit installation with female and male header,* Built-in 5V regulator,

Back in the time when I was building my Arduino based Ludwik Drone I faced a problem of choosing proper motors and propellers. I didn't know anything about drones at that time so I had to trust motor manufacturer and the datasheet of a motor those are most likely to be a good source of information but what if you want to combine different motors and propellers together? Then here you have a simple DIY thrust stand!More info about this project can be found in my YouTube video and on Instructables:https://www.instructables.com/id/Brushless-Motor-Thrust-StandTensometric beam: https://goo.gl/e2aDRALCD: https://goo.gl/WF7dPEMotor + ESC + prop: https://goo.gl/93v2QBCurrent sensor: https://goo.gl/w6bZDTBuzzer: https://goo.gl/PC54mL2 hole screw terminal: https://goo.gl/e4BmGQ3 hole screw therminal: https://goo.gl/28i28NPotentiometer: https://goo.gl/qnsGZq

### DESCRIPTIONWe can easily find many types of digital optocouplers but its very rare to see any analog optocoupler application especially in hobby electronics. Even though its very essential in many type of analog circuits especially in current and voltage monitoring/measuring circuits where input and output side should have isolation. If someone is measuring/monitoring the high DC voltages or current ,and its also driving inductive loads, then it can easily damage MCU or any other measuring hardware. To solve this sort of problems analog optocouplers are used.Here I am sharing circuit of one of analog optocoupler using easily available components.tinyMoster - Analog Opto-Isolator module to provide ground isolation between 2 analog signals### TECHNICAL DETAILS / COMPONENTSArduino, ESP8266, STM32 compatible output.Applications: High Current and Voltage Measurement Low cost analog isolation SMPS feedback loop, SMPS feedforward Monitor motor supply voltageThis circuit was designed to take part in Element14 community Test & Measurement Contest and this is the refined Version of Previously tested Circuit.More Details and Testing Videos Can be found here:Precision analog opto-isolationTesting and Demo

Everyday Carry (EDC) Heater Imagine that you are in a harsh cold island. You only have a USB source, and nothing else to make you survive.EDCHeater can help you to be warmed up in chill situations!You can even keep your favorite drinks warm! Moreover, homeless animals can keep warm in cold climates with a simple power bank, and this piece of life source for hours, and even days!Let's make all hearts happy!Technical Details Front View of Board 1To prevent short circuits, and to make more lovely design, this board is designed as enclosure. Snowflakes are designed as solder mask clearances. I just illustrated them as like white leds are operated in real application. If you order this board, especially note that this is a two layer board with no copper on top layer. Else you might get a board like on right picture :)Bottom View of Board 1White regions show where Z-axis milling process is needed (1.5mm depth) . Board 2 components will fit in those regions. Also you can order without milling and engrave it yourself :)Be careful that big electronics components need a little bit more space. So it is really hard to make a perfect enclosure by hand, as you can see from right picture :) Bare copper square pads are necessary to solder and assemble two boards together.Copper plane is added to store heat. Front View of Board 2-Heater ( Below image shows the trace resistance configuration. Approximately 650mA of current will pass through and this equals to 3.25W power consumption. It took many hours to measure every length of the traces one by one and calibrate it. I will try a better approximation for next designs. )http://circuitcalculator.com/wordpress/2006/01/24/trace-resistance-calculator-Micro USB connection,-White LED’s are for lighting and also to prevent power bank's low current sleep mode.-60C degrees overheat protection circuit. If you use better Op-Amp with higher operating temperatures, you can easily configure it through online NTC Thermistor Resistance Calculators. Below image shows the configuration that I’ve made from: https://www.electro-tech-online.com/tools/thermistor-resistance-calculator.php-TSM3404 MOSFET (You can use any alternative generic N Channel MOSFET that has drain current higher than 1 Amps. Be careful with pin configuration!! ) -OpAmp is used as voltage comparator. Main logic relies on this basic circuitry (Heater resistance is added to drain pin of MOSFET in layout).Bottom View of Board 2Power rail of white leds and essential components. I tried to make it more stylish :) Electronics components are kept as simple as possible. So that everyone can make it. If you order these boards, I will help you through comments below as best as I can. This is my first experience with KiCad. So I'm open to any suggestions :) Board SpecificationsSize:70mm x 70mmThickness: 1.6mmFR4-TG: TG130-140Track/Spacing: 6/6milHole Size: 0.3mmBlack Solder Mask White Silkscreen(You can choose another fashionable colors that you like:) )Tenting Vias1 oz CuZ-axis milling: 1.5mm depth (Bottom Silk of Board 1 is for Z-axis milling)Order number on board is not necessary Extra Notes-Especially write that board 1 is two layer. Else they might send single layer board with no solder mask on top layer. -You can also order stencil for better look and easy assembly. If you are not experienced with stencil and wave soldering, PCBWay has discount for automated assembly. -Board 2 is essential and Board 1 is optional to maket his project. I would prefer Board 2 if you have an experience with wave soldering. Because you can only assemble two boards together with wave soldering tecnique. Never forget to isolate top components with some kind of enclosure for your own safety.-Finally, everything is open source! Feel free to ask any questions. I will guide you best as I can.

GeneralNixie Tap is a minimal device which will elegantly display information in living rooms, work desks and bedrooms. Current features are:- device is USB powered- network time and date synchronization- automatic DST adjustment- optional manual synchronization- provided functions for cryptocurrency and temperature display- all tubes are IN-12B (with dot for every digit)ConfigurationAt the heart of the product lies the ESP8266, namely the ESP-12F variant. At device power-on, the ESP serves a hotspot, which is used for configuration. This is where the user configures the Nixie Tap with the following features (to be expanded):- WiFi network credentials- manual time and date setting- display format (24h or 12h)- cryptocurrency price display Once the configuration is finished, the ESP goes online and picks up the required information.Circuit overviewDriver section is based on HV5812, which is a high-voltage shift register made by Microchip. Since this device uses 5V logic, and ESP is 3.3V rated, a HC595 was inserted, to act as a level shifter for the SPI chain.To be able to generate 170V requred for Nixies, and still be powered via USB, a special PSU was designed around the FP5139. This is a switcher IC made by Feeling Technology from Shenzhen.An RTC chip is also present on board, to keep accurate time and offload the tasks from the ESP.For more information, please visit the Hackaday.io page.Nixie BoardThis project has an additional PCB, the one which holds the IN-12B tubes.To order that PCB, please visit the PCBWay page.
