Hi, I currently have a circuit that has manual 'switches' in it. Currently there is a piece of plastic that spins around on a shaft, hit hits two manual contact switches depending on which way it is spinning. This is not a good design as each time it hits the switch it 'slows' it down from spinning. So we want to redesign this system as basic as possible using HALL SENSOR. So it detects the spinning, which way it is spinning, then triggers opto isolator output depending on which way it is spinning, clock wise or anti clock wise. New circuit board will - Detect spinning - Detect clock wise or anticlockwise - Send output depending on direction to an opt isolator. Please refer to diagrams hopefully they show some further info of what I am trying to a...

Bonjour, Nous aurions besoin d'un modélisation 3D, imprimable pour un boitier plastique afin d'y intégrer un circuit imprimé. Le but est de remplacer le boitier d'origine, pour le rendre le plus plat possible. Il doit comporter un trou ou être composé d'une partir transparente afin de voir une led s'allumer à l'action d'un bouton. Il doit comporter un emplacement pour le bouton. Il doit être composer de deux partie afin de pouvoir en changer la pile. Le reste des modalité et les précisions des dimensions seront à voir lors de notre premier échange. A tout bientôt. Cordialement.
We are in the business of pcb boards, printed circuit boards and we need 5 images to represent certain types of boards (ENIPIG, HDI, Ceramic, Flexible, Flex Rigid). I cannot find these images on shutterstock or other leading photo gallery websites. Would you be able to design 5 consistent images to convey these types of printed circuit boards? We want to put them on our website and let people know that we can source these types of boards for them.. Please let me know if you are interested and I will send you a link of the page where I have some info.

Project Description: Using schematics from a current GPS survey unit as a guideline, create a new schematic for a prototype survey unit. Much of the work will be simple "copy and paste" of schematics. Certain parts of the guideline schematics that are not needed should be removed. A serial port should be added for connection to older serial devices. The battery charge and protection circuit should be improved/designed so that two 3500mah batteries can be safely recharged in 4 hours. Support should be provided during the prototype building and testing phase. Once the prototype has been tested and approved, the schematic should be placed on a production PCB approximately 110mm in diameter. The U-BLOCK ZED-F9P should be placed on a PCB hat so future replacement with other GN...
Need this re-designed to these specifications: I've included a green background with water drops and maybe you can a circuit board representing a supercomputer in water. blue (representing our liquid cooling technology) or green (our environmental sustainability story) along with water and some sort of computing (circuit board, CPU, etc.)
I need two wires soldered to the circuit board on my headphones. I was going to attempt to do it myself but panicked. I have the wires unattached from the circuit board but I’m too scared that I’m going to destroy the board by attempting to reattach them. I want someone who knows what they are doing to do it. It’s two dots of solder. It could probably be done in a few minutes.

This project is part of a medical device prototype. It is a 110V output amplifier, capable of delivering between 100-3000 watts into an 225 Ohm load electromagnet, operating at frequencies from 4-300 Hz. The ELF parameters made the oscillator circuit of special interest. A simple R555 chip setup may be adequate, though several may be necessary to for complex waveforms.

...it into segments and generates XML for each segment The above processes work properly when I work with UCS2. But in messages that are longer than 160 characters in English that should be encoded in GSM-7BIT messages of 160 characters. The messages are cut off (missing letters) or (weird characters are added) in short, the messages arrive with broken text. The task is to fix the sending and receiving of the long messages in English. in a normal way and without missing or adding letters (and if there are additional bugs that you did not raise in the code to fix them) I suspect it is related to GSM 7-bit encoding with 1 bit padding but not sure There is this article that explains quite a bit about it https://github
I have a working prototype using Arduino MEGA, however, I would not like to use an Arduino mega for the final product. I would like to have the circuit converted to without it. It is a very simple project. Possibly extra work if you would like to design the simple PCB as well, of course I'd pay extra!

...to read the signal, display it on a small screen, and allow for a user selectable delay to close a circuit. The trigger will actuate a raspberry pi. I am looking for someone to design and build me 2 or 3 physical triggers. The objective is to create an electronic trigger that is actuated via LTC timecode input. Input Signal: LTC Timecode via 3.5mm audio Jack (the sound is mono, need to check the channel) LTC is a manchester encoded signal, wikipedia has information about it. Each frame end is terminated with 12 highs. I need a small display to show the decoded timecode. I need to be able to add a user defined delay to the triggering mechanism. The triggering needs to close a circuit to actuate a raspberry pi. I also need a mechanism to send the timecode informa...

I am trying to work out a bespoke electrical circuit for a slave / tandem heating system which includes a gavity fed standard Y configuration CH and HW gas boiler with a mid port valve and now a slave pellet boiler stove. The pellet boiler stove has an integral pump which activates when the water in the boiler reaches 70c. At this stage I want the system pump to be activated and water to be pump into the HW cylinder until the cylinder thermostat reaches 70c at this stage the mid port valve would activate both grey and white wires to dump ongoing hot water into the central heating. Importantly I want it to do this using the existing system pump, mid port valve and cylinder thermostat that is part of the gas system. It is the case that the two ststem will not run at the same time....
