Metal Melting Induction Heater Using PCB Board(Firmware & Other)
Hi! I'm interested in building a customized Metal Melting Induction heater using Transformers and other electronic and electrical components. I'm looking forward to build a Metal Melting Furnace which will be electrical mainly for the purpose of melting and refining Gold , Platinum , Silver and Iron. I'm looking forward to work with someone who is expert in PCB Designing and deployment and most importantly who has enough patience to answer all my doubts and questions throughout the project. Someone who is well versed with electrical and electronic components , firmware , hardware and PCB Design will be best suited for the project. What I'm looking for: 1) A Metal Melting Furnace using PCB Board , various electrical and electronic components , firmware and hardware. 2) It should have feature of increasing and decreasing Temperature manually as per the requirement of melting point of different metals. 3) A ON/OFF Switch button , temperature indicator in Degree Celsius , increasing and decreasing temperature buttons to set the exact temperature and voltage indicator are must. 4) A "SET" Button. This button when Pressed will maintain the constant desired temperature. For example the melting point of Iron is 1800 Degree Celsius. Once the furnace reaches this point and this button should be pressed so that there is not drop or increase in temperature irrespective of external conditions or other conditions. 5) Maximum melting point to be reached is 2100 Degree Celsius. 6) It should be able to reach those temperatures within 10-15 minutes. 7) It should be compact , lightweight and can easily be moved from one place to other(although this is not a major requirement if we have to compromise on it's quality or design to achieve the same but I believe that something like this can be achieved considering the fact that we live in advance age) 8) It should be able to work with the help of capacitor batteries or any other Lithium Ion battery/Solar batteries or the batteries which are used in Trucks or any other external source of battery. 9) It should be able to take in 240V of electricity since in my country its the standard 3-pin socket output provided by the government. 10) It should be able to hold crucible for melting the metals. For reference I have included a few pictures of my idea of the design , you are welcome to share yours and guide me along the way pointing out any flaws or cons of the same , thereby suggesting something economical as well as good performer at the same time. 11) Most importantly incase there is some major voltage fluctuation during its operation , there should be some very strong safety measures built into it to avoid any major accidents. 12) The components used in the project should be economical(since wearing of components will occur over the course of time and hence very costly components need not be installed) easily available(although this is not a compulsory requirement if quality will be compromised) 13) You will have to design the entire circuit board , a board which is not sub-standard in quality but above a certain threshold of quality but at the same time which will be economical to produce. 14) Since it is a furnace its maximum weight holding capacity including the weight of the crucible should be 6Kgs. 15) It should also be able to work with lesser weight such as from 50 Grams. External design/look of the furnace can be worked out later once the design and testing is completed. 16) The Total weight of all the electrical components including PCB should not be more than 10Kgs. 17) A Graphite crucible will be used for holding the metals. 18) The project needs to be completed within 180 Days from the date of you joining the project. If you can check all the above 18 points , you are welcome to join the project. Minor adjustments can be made here and there but not all of the above 18 points can be compromised because otherwise it will defeat the very purpose of posting this project. Please note this is not for mass production or commercial use. Thank you.

Design / Engineer PCB board for IoT (ESP32 and Lorawan)
Design/engineer a PCB board for IoT with the ESP32 module. I will need: - Source files for production/print (Gerber) - Realistic Photo / Look - Fritzing version (for user instruction) - Specifications / Instructions for manufacturer The board will be used to connect many sensors, some with different voltages or different output types (Analog, Modbus, Digital 0-5v), so idea is to have a very user-friendly modular board that supports all (36+) the sensors (electronically). Sensors will be connected depends on available and use able slots. The PCB board will include terminal place for: - ESP32 (ESP32-U CH9102) - LoraWAN as transmitter/receiver (* optional for user) - LoRa SX1278 https://www.aliexpress.com/item/32791728376.html - Lora: https://www.aliexpress.com/item/1005005105890721.html - It should be able to wake up ESP32 (so ESP32 can have a sleep) - ADS1115 Module ADC 16 Bit I2C (* optional for user) https://www.aliexpress.com/item/1005001636468832.html - MAX485 Module => for use with modbus sensors (* Optional for user) Communication & Voltage support: - Support for SPI, I2C BUS, Mod-bus, 485, Serial, Digital Pins, Analog pins - Level shifters 12v to 9v and 5v to power the sensors and boards - level shifter for signals (I'm not sure if its a problem with ESP32, but with ESP8266 the analog pin could support max 1v on Analog input signal so analog sensors signal up to 5v required level shifter) Inputs: - 6x* 4p SDA/SLA IC input jst-ph connector (or any other you recommend) - 5x* 4p Digital inputs (female pin connector) - 3x* 3p Digital male pins for digital inputs (not sure if any resisor is needed..some sensor do seem to need) - 3x* Analog - digital input using ADS - Modbus/485 - ??485 to IC/232 * Exact amount depends on available ESP32 pins and combinations - ?Status Led - ?Reset Button - Selection for 9v or 12v power for the modbus/485 - Text: Ports Type and Pin numbers on board, voltages and other info + Logo - Corner holes for screws Power: - From USB using ESP32: And it powers board 3.33-5 v and sensors in this voltage range - Jack power (9-12v or only 12v): In case one or multiple sensors require 9v/12v Notes: - The board will be also used in off-grid mode => with solar panel and battery (charging unit is external and not needed in this board), so note the efficiency and low energy usage of board. - With LoraWAN module: Note the wake up function to wake up ESP32 (Electrical wiring point of view) - Note: some say that the 5v output of esp32 is not stable and effects sensors, maybe needs to be addressed: https://community.home-assistant.io/t/esphome-water-pressure-sensor-do-not-get-correct-values/306606/8 - See similar concept board: https://shop.sowillo.com/product/ultimate-iot-board-dc-kit/

I need 3 PCB drawings/designs
I am looking for a designer to create images of three PCBs (printed circuit boards), named as below: 1. Evaluation Kit PCB (9.7cm x 7cm) (file name: Disc Pump Eval Kit - v7 - hi-res.jpg) 2. Breakout PCB (2cm x 2.6cm) (file name: Disc Pump Drive PCB.jpeg) 3. Generic PCB (TBD) I have provided a photograph of Evaluation Kit PCB and the Breakout PCB. I am looking to have the photos turned into line drawings that reflect all detail seen in the photograph. The Generic PCB will need to be a newly created image, that is a different shape - perhaps an 'L' shape - but similar in size to the Breakout PCB. This can be entirely made up - if you google 'Printed Circuit boards' you will find a variety of shapes and sizes & layouts to choose from. I would like a Black & White and Colour version for each image. Files to be supplied at the end of the project: - AI or Indesign (if possible) - Jpeg - PDF Happy to discuss further of course. Emma

PCB design required for water sensor
I would like a PCB designed with relatively simple purpose. It will act as a moisture sensor, i.e. when the sensor is submerged it is active, when not submerged inactive. The majority of the time, the unit will be asleep. When sleeping it needs to consume minimal current, i.e. tens of micro amps or less. On the rising or falling edge from the sensor (i.e. rising edge = sensor is submerged, falling edge = sensor is now dry), the unit needs to wake up, send an SMS message, and then go back to sleep. Components: -GSM module (e.g. SIM800/900) -Microcontroller with low powered sleep -External moisture sensor -Power circuitry (power source will either be alkaline batteries, or 3.7v lithium cell) Features: - As small as possible - Microcontroller ideally Arduino bootloader compatible - Initial through-hole design (using suitable GSM module)

3d model for Urethane casting, single piece 90mmx120mmx5mm
I have a pcb 80mm x 110mm and I'd like a case proototyped. I've looked at facfox & want to prototype the bottom of the case in abs style casting. There are some pictures of the pcb on colddevices.com, the 3d model for the lower part obviously has holes for the screws and some kind of lip to mate with the top of the case (I will not make the top of the case yet, i want to see how the bottom looks first. so it's a simple model, but need support also to get the file loaded into facfox. let me know if any questions..
