    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.

    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...

    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.

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
