DC current source design

I could complete this project using logic ICs or microcontroller, whichever you wish. The microcontroller solution would be smaller but a little more complex as you have to program the microcontroller, however doing this with digital logic ICs would require a bigger space and more component count, however it is fairly easier to get it working.

hi sir i am an expert electrical engineer I can do it for you I have almost 7 years of experience in this field Please have a look at my profile I am waiting for your reply to start the project Regards

I am an Electrical Engineer having specialization in Electronics and Control, teaching in Electrical Department at FAST National University Pakistan. I am also per-suing my MS degree in Electrical Engineering with specialization in CONTROL. I have taught the followings courses, and also done many projects related to these subjects as well as related to consumer electronics products. 1. Control System Design & Modelling (Matlab & Simulink) 2. Digital Logic Design (Verilog, VHDL, Logisim) 3. Digital System Design (Verilog, VHDL, Logisim) 4. Computer organization & Assembly Language (8086 processor, 8051 controller, Arduino, PIC) 5. Electric Machines Design and Analysis 6. Circuit Analysis and Designe etc 7. PCB Design (Proteous AREAS + Multisim Ultiboard + Altium Designer) I assure you, if you assign your project to me, you surely gonna work with me in future.

Hello, Have a Great day. We are Electronic devics and prototyping company. We will deliver you a complete circuit diagram and PCB layout. The required circuit needs a Voltage controlled Current circuit, controlled by a microcontroller. We have a video to share for te same circuit. Please feel free to contact us. Best Regards, Shahbaz.

Hi I am interested to this project. I a familiar with electronics, PIC microcontroller as well as PCB design by eagle. Thanks.

I have over 35 years experience as an electronic design engineer, please see my profile for more details The current price and timescales are only place holders to allow me to communicate with you I am sure I can design this for you. However instead of starting from scratch please send me your current circuit to see how best to modify it to your new requirements. I assume that each press of the up button would cycle through current sources 1 to 4? By the way the circuit would be simpler if you only had an up button instead of both up and down Best Regards Dave Lelievre

hi i am an electrical engineer. i have strong skill set related to circuit design and electronics. i have experience with current sources. i can do this project for you. let me know if you are interested and we will discuss the details.

I have over 27 years experience in mixed signal and power electronics design. Currently working in the aerospace industrry. Your requirements certainly can be achieved. I can provide you a schematic to suit your requirements and even a PCB layout if required. At a small additional cost I can also provide a working prototype.

Hi, I can design for you electric diagram wit 2 Logic IC-s that meet your requirements. Slavi.

Dear Sir, I can help you with your project. It can be done using simple low-cost chip and 2-3 transistors. If you want, you can send your circuit to me and I'll modify it in a manner you want.

Can do, using 2 to 4 multiplexer. Need your schematic and simulation software.

Hello! We are experienced with hundreds of reviews on this website. We have all the required skills and would love to work with you on this project, please reply back to discuss further. Thank you!

I can make this DC current source with LM334z, a few transistors, a register and two buttons. I would provide you with a detailed schematic, bill of materials (list of components used), and a detailed explanation of how said circuit works. Before I begin, I would need to know which four current levels you want. Also, do you intend to build this device on a breadboard or you want to make a printed circuit board. If it is the latter, I will provide you with PCB design done in Altium. If you have any questions, or further demands, feel free to tell me. Looking forward to our cooperation, Cheers V

We would Design The Variable DC source with given conditions in the given time and with 100% precision. Electronics for newbies

The easiest way to do this is to use microcontroller. This will require to do some programming, which I also can do for you.

I will help you for free. It looks like a simple task, you just need to clarify me something. -----------------------------------------

Hi, It would be a pleasure to work for you.I have 14 years experience in PCB design and fairly new to Freelancer. I have extensive knowledge of working with Altium, Eagle and Easy-PC PCB. For the last 5 years I have been working on high voltage, high power designs as well as low voltage micro-controller projects. My experience with analog circuits will help me solve your design problem. I have already few solution in mind to replace 4 position selector with just 2 up/down switches. I will keep design simple with low components count, so you can easily follow and replicate. Cheers

Aucune proposition n'a encore été fournie.

yes it is possible this is a pretty easy and simple job for me I will do this job in hours but still now I cant tell you how I will do that because that's the trik and I am gona earn from that I am bidding too low because I want to make my profile
