Dear Elancers, I'm was looking for buying a Honeywell resistor board (Honeywell-221508A) but unfortunately I couldn't find it and it's out of stock in most market areas. So I decided to make it by my self which I think it's not very complicated. It's just an analog card with mosfet. I'm looking for someone who help me for building this resistor board and give me some advice for the board. Please pay attention that I only need your advice and help for this so it's not a hard job. in the attachment you will find the pic of the board. Looking forward to hearing from you, Thanks,

I need developed complete electronics (populated PCB) as described here:   [obscured]  /controller/ Long term production will be required and I will need a cost per unit/ in volume of 5-10 units but production is NOT a part of this platform. Just the development which includes the design and working test unit. I'll need all paperwork associated with the design. Each time we re-designed we improved the end product substantially. That is why I am making this query. This will be our last improvement (I said that before) so it needs to be done correctly. Note: I have several versions in the worldwide market since 2008 so I know EXACTLY what my costs are. Any/all bullshit will be ignored. I wasn't born last night. Note: This is high school 101 electronics, very simple, uncomplicated. Note: I do NOT want to hear about your qualifications, your team, blah, blah, blah. Either you contact me to get to work or leave me alone! Note: If you have responded previously, you...

We are a start-up (  [obscured]  ) developing and manufacturing integrated micro-electronics circuits (chips) that are used by scientific community to study neurons and in particular neuronal networks and retina. For instance, a network of neurons derived from stem cells can be cultured on our chip up to form a sort of "mini-brain" and then our chip is able to sense the electrical activity of the neurons (which is the language used by neurons to communicate) in order to study neurodegenerative diseases such as Alzheimer's Disease. Our devices represent the interface between the neuro-biological world and the digital-electronic world. The novelty is that our chip integrates thousands of sensors (each sensor can interface with a neuron, hence we can read-out from thousands of them), while past devices had only ~60 sensors. We need an illustration (either 2D or 3D) to express these two main concepts: (i) neuro-chip interface and (ii) high-resolution. The illustration should sh...

I would like bids on designing the circuits, providing gerber files, writing code and providing a test article. This item will be FCC certified in the US and must meet all compliance requirements. This device will be based on the following CML chip while operating and approved only in the MURS bands to avoid FCC operator license requirements.   [obscured]  /products/CMX883_Baseband_Processor_for_FRS_MURS_PMR446_and_GMRS_Leisure_Radios/ I would like the bids to include the incorporation of a GPS chip with antenna and routines to locate the distance, bearing and position of another matching radio. I have identified the formula that will handle this. The screen should be four lines with OLED yellow display. There will be about 20 menu screens to set up groups, poll locations, text both ways, review old messages This will be a small qwerty keyboard similar to Blackberry. There will be no voice capability included. I need someone with strong radio design skills and a circui...
