...Transistor/FET controlled for use as pulse out. Circuit should be capable of being powered by typical usb from laptop or alternate power supply, but built using usb-c preferably. Input power should range from 5VDC to 30VDC or higher. Adjustable output voltage up to 30 VDC minimum with 16 bit resolution. Adjustable output current up to 2 amps minimum with 16 bit resolution. Preference is to have a socket for the Arduino (embedded Bluetooth and UART) or the ESP32 (embedded Bluetooth and UART) in the case of failure. Drawings, schematics, and GERBER files should be included as well as a bill of materials, along with two working prototypes. Bonus: it would be nice for battery powered, while charging from the same one usb input. Estimated battery life should be calculated for 24VD...

...Shield, and MKR GPS Shield; these designs are open-source and available in Eagle for ready reference. Additional features to be added include a switching power supply, 0-20mA current loop input support, and test pads/external interconnects. Software is already developed, so pin-compatibility with existing shields is preferred. Design goals include: *** Integration of existing modules *** 1) Socket compatibility with the MKR WiFi 1010, MKR WAN 1310, and MKR GSM 1400 modules 2) Integration of the BNO055 IMU module from the MKR IMU 3) Integration of the SD card portion of the MKR Mem Shield (flash memory is not necessary) 4) Integration of the uBlox GPS from the MKR GPS Shield, including battery backup. NOTE: the MKR GPS requires external wiring that we want to incorporate into t...

Following are few I have reviewed and these are quite close to what I am looking for a client which is a staff management company. Have a look into the following selective ones and let me know if you can develop something similar to any of these. https://www.alloc8.io/ Our requirement is to make change inhouse hence it is not suitable to buy off the shelf however if anyone already in progress of a similar software then we are happy to see its demo provided you own 100% of its code. This will save time if we plan to develop it from scratch.

We have a Framework7 project which we would like to migrate to a Bootstrap setup. Framework7 is a jQuery based framework for webb mobile first applications (please look into framework7.io). It is practical for prototyping, but we need our project to be more dynamic and also match with a web version based on Bootstrap. The task is to migrate the code to a Bootstrap framework. Very much of the code (javascript and jQuery) can be kept as is. Also the API parts can be left. It is mainly the display parts, showing modals, forms, navigation etc that needs refactoring to match Bootstrap instead of Framework7. It is also a desire to have the content translateable (e.g. language file, php based?). First part of the project will just be to make an feasability study to assess the scope of t...

Hi I need someone with Java 8+ Socket expertise to improve my super simple NIO Socket client and server implementations for a super simple scenario. This socket is ONLY for passing Strings between JVMs. The socket interface has only one method ... public String method(String s); Currently I have a working implementation (see attached), but I'm sure I am making "beginners mistakes". I need someone to clean up my solution. It needs to be clean, clear, maintainable and robust and must use "vanilla" Java 8+ Sockets. Background notes: Our current web application runs both the web-server and backend on the one JVM. This works nicely. I want to split the web-server and backend onto different JVMs - on the same "localhost" / Linux...

SECURITY OF IOT-SERVER CONNECTION To prevent rogue attacks on the IoT network, security of communication between the asset and server is required. This requires Detecting Unusual Behaviour Of A Particular Socket(MQTT based or TCP/IP) or Whitelisting like measures to be deployed 2. QUOTA CONSTRAINTS OF AN IOT-SERVER CONNECTION To prevent undesirable events of instances shutting down due to overhaul or unexpected billing events. 3.
