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.

TASK CARDS ILLUSTRATIONS
11 X TASK CARDS TO PRODUCE ILLUSTRATIONS FOR. This is a typical task card below... How to Clean a Toilet Task Card It is essential to keep toilets clean. A dirty toilet will look bad, smell bad and breed germs. Use these instructions to guide you through this task quickly and efficiently. Equipment Required 1. Safety Signs, PPE – Gloves plus any additional PPE specific to the chemical. 2. Bucket and cleaning cloth colour coded (red), abrasive pad. 3. Toilet Brush & holder. 4. Toilet Cleaning Solution. Preparation 1. Place safety signs, wear appropriate PPE. 2. Check bucket is clean and ready to use. If dirty, rinse out with clean water. 3. Fill bucket half way with warm water 4. Add the correct cleaning solution for the task to the water according to directions on the label. (Note: always add chemical to water, not the other way round as to avoid chemical splashing). 5. If possible, ventilate the room i.e. open windows. Cleaning the Toilet 1. Flush the toilet with seat lid closed. 2. Reveal water line by pushing back water in the toilet bowl with toilet brush. 3. Apply toilet cleaner to the inside of the bowl, including under the rim and allow several minutes contact time. 4. Place cloth colour coded (red) into bucket to absorb cleaning solution. 5. Wring excess solution/ water from the cloth. 6. Start wiping the outside and around the toilet, including toilet roll holder, pipework, toilet brush holder, cistern & handle, toilet seat lid (top & underneath) and hinges. 7. When you have covered a small area or when the cloth is dirty, insert the cloth back into the bucket. Wring the cloth and move to the next area to be cleaned. Take care to avoid splashes to other surfaces, if this occurs then wipe clean with a damp cloth. 8. For heavy soiled areas apply pressure to the cloth or use the abrasive pad for stubborn marks. 9. Scrub inside the bowl with the toilet brush, particularly any stains, water line and under rim. 10. Flush toilet rinsing the brush in flushing water. Replace brush in holder. 11. Dry toilet seat with cloth, then close the lid. Final Stages 1. Discard dirty water from the bucket. 2. Clean and dry the bucket. 3. Dispose/launder the cloth. 4. Remove safety sign when area is dry and clear of trip hazards. Close any windows previously opened for ventilation. This task card is offered as guidance only. It is your responsibility to ensure that it reflects the use of the product in your operation and amend accordingly __________________________________________________________ SEE PDF AS AN EXAMPLE... There will be 11 versions of this with different clean task and illustrations needs all in the same style of illustration. THANK YOU POSSIBLE 264 ILLUSTRATIONS TO BE CREATED
