I need to create a 50-volt peak-to-peak triangle wave at approx 40khz, very low current (50ma or less), from a 5-volt input source. Your task will be to design a circuit (as small and simple as possible), then build and test and video it - like this (unrelated) example: [login to view URL] I will be needing to rebuild this myself, so my preference in selecting the winning worker will be someone who says they will also tell me where and how to order the parts for this. Optionally, if you're willing to post me a working completed circuit, to Australia, let me know that you will do this, and add enough onto your price to cover parts and shipping. Folks willing to go to this extra effort will be top of my selection criteria. Deliverables will include: circuit diagram with explanation about how it works, parts list, and video showing a working test of the circuit. Optional deliverables: how and where to order parts instructions, or even better, completed working and tested circuit shipped air-mail to me in Australia. When responding to this project, please use my name - Chris - at the start, so I can easily separate the spammers from the guys who read to the end - thanks :-)

Its an interesting job indeed. I will build one and will send you the sample. Please note that I may use different technique to produce this 50V triangle waveform probably without using inductor/coils. Please let me know if you need this to be precise 50V or it doesnt matter if its 48V~52V ? Charge pump may increase the voltage and then will make it triangle shaped waveform. The amount I placed here covers designing the the schematic, building the working module and shipment to AU. I will also provide support till the time you build it again at your place and also the PCB design. I will make it in a home made PCB. Thank you very much and I am looking forward to hear from you soon. Best Regards... Roy

Hi Chris, We are a multidisciplinary engineers group that make three form of design, pcb, structural, and firmware design. We normally use professionals software platforms like Altium for pcb design, Inventor or Solidworks for structural design, and Atmel Studio for Firmware design. We have make many jobs related with led light design, temperature system control, distance measure indicator with ultrasonic system, servo controller system, inter alia. What's more, we made many types of cnc machine design, and automatisations systems. Also, we made many plc siemen's program related with logo line of siemens, with logo line of siemens we made a automatisations of industrial's machines, like linear rectifier, cnc protection controller, special electric motor controller. We have some experience with ladder diagrams for sequential systems. If you want to see some our work, we can send to you images or example design about that. We have some experience about electronic design, if you have any question, contact us. Best Regards IDSM Solution
