We need help setting up a custom OpenHab project, on a Raspberry Pi. Program must be scripted to measure a voltage, and flip up to 4 relays. We will need the program written, a list of parts needed to perform this task, and lots of guidance on putting it all together and making this work. We do have some experience in soldering and putting components together, but will require help for all complications. This will be considered phase 1 of the project. After this is complete, we may ask you back to help phase 2, and 3 as we word towards a production model. A NDA may be required as we mov...

A reader will then read the tag and say (with a speaker) my pre-programmed voice. I have an arduino and have a very elementary understanding of how it works. I would like to use cheaper parts so that I can eventually mass produce it (such as the RFID-RC522 and an ATmega328 - or any other ideas you have). Please know exactly what I would need to buy, instructions how to put it together (soldering if necessary) and the programming to accomplish this task. Th...

Conditions… $1000 if: 1. You can get the boards with chip manufactured within a timeframe form your manufacturer…the finished board with chip needs to arrive to me by the 1st of May and working…give or take a couple of days… 2. You get me the spring thing you talked to me about so no soldering is necessary to programme the board…and explain how to use and programme with it…I will programme the sensor… NOTE: if sensor arrives after the7th of may only a $400 BONUS IS PAID Obviously I will pay for the manufacturing and shipping costs as soon as the manufacturer invoice me…

I need someone that can write articles in the electronic industry. Specifically on Printed Circuit Boards. Topics : - PCB surface finishing techniques (OSP, HAL, Gold Plating,...). Pros and cons - How a PCB is made (describe how a 2-layer PCB is made) - Materials available for PCB manuacturing. Pros and cons - Defining temperature of soldering on a PCB (what temperature ranges are optimal depending on the material chosen. Limit it to the most common materials for eg FR-4) - PCB pooling for prototype orders. Using a pool of different projects/clients we can reduce manufacturing costs for low quantity orders. Other subjects will come. I need a 500-800 words article for the topics. Good english and good technical knowledge. Experience in electronics required.

Please read the entire project. I just need a problem solved, but the problem must be solved in a way that is compliant with UL. I have a PCB already designed that requires pin-out of two male terminal pins that: - can fit inside a footprint of 2.4mm x 4.8mm, - is UL-compliant or UL-listed SMT pins, - is suitable for automated pick-and-place machines and reflow soldering. PCB is a tiny 5mm x 5mm size, which will only need to process 80mA at 12v, but needs to be UL compliant. Need you to: - search and locate suitable male pins, and - take our existing design and ensure compatibility with the pins.

I have the schematics and the layers artwork (back side, component side, serigraphic, soldering mask...) of an electronic 2-layers board BUT ONLY IN PDF FORMAT. I need a freelancer for loading the schematics into an Electronic CAD (like ORCAD or PADS), exacly reproducing the ones I already have; furthermore, he must create again the pcb according to the schematics and copying the actual layout. In other words, i can supply everything in a good pdf format and i need back the schematics and the pcb in ECAD format, Orcad or (better) PADS In anex you can find the pcb in order to evaluate the complexity; external dimensions are around 330x90 mm If we find a good cooperation, I have other 4 similar projects

I like you to do an Eagle CAD design with the LTC3105 as was done here: https://www.freelancer.com/jobs/Engineering-Electronics/Solar-Cell-Board/ The necessary design has been described here: on page 5 figure 8 The complete board should be as small as possible. SMD soldering is no problem for me. The input solar cells will be: (or similar ones). The board will be used for charging a LiPo battery (nominal 3.7 Volt and max. 4.2 Volt) and should also have a load connection. The load will be a small wildlife GPS GSM tracker (normally running on such LiPo battery). This tracker sleeps most of the time with only its mcu running

When the bottom button is pressed the motor runs backwards until the middle stop button is pressed or until the limit switch 2 is pressed.. which ever comes first. Guild lines: - Parts and components MUST be easily sourced and MUST be cheap! - PCB to use as few components as possible (to allow lower cost when in production and to allow less soldering time needed saving money) - I will also need the PCB files so we can send it off to have thousands printed after prototype + I will need the components list. - PCB to be single sided, single layered ONLY. - PCB to be no larger then 50mm x 40mm with 2mm boarder (no components etc on boarder - so build area is only 46mm x 36mm). - The PCB size is very strict.

I need a simple project based on SIM900A+ATMETA328 done. 1) I need this board designed for components available easily. 2) Testable / Repairable (instructions to be given) 3) SIM900A board pins are very closeby, manual soldering can be a issue, so I need a separate broard just for SIM900A chip. So that it can be soldered and tested separately (its the most expensive component on the board). 4) I need a http rest call to happen every 2 mins (the time duration should be programmable remotely via sms, hardcoded password) 5) LED's to indicate status of board 6) 4 LED's to indicate status of the return value of the http rest call. The http rest call will return 1, 2, 3 or 4. The LED's should light up accordingly. 7) Should work for days without burning out 8) Powe...

I wanted to extend capabilities of the beagleboard-xM. The original beagleboard-xM was already pcb layouted (6 layers) in Altium. I also change the BOM to include a NAND memory instead of the old one. However my pcb manufacturer doesn't have the know-how to do PoP soldering. I need convert the project by separating memory from the top of the cpu and have it placed on the PCB layer alongside of the Omap 3730 processor. I need a skilled electrical engineer to help me to achieve this job, all in Alitum. The placement job in Altium should take care of the impedance adaptation with equal length tracks, because of the CPU-RAM speed. Thank you very much !

Hi I have a PC and a Acer HD projector the PC screen can rotate, landscape, portrait and flip upside down BUT my projector can reverse back to front (most projectors can do this because they are designed to project on a opaque screen from behind) but no PC`s can do this but it should be simple to hack int a DVI connector and switch the X and Y screen orientation ( soldering wires etc ) Regards Paul

I'm looking to get a couple thousand 7mm x 7mm PCBs made for a 5050 SMD style LED. I don't know much about PCB design but I think it's a fairly straight forward idea. I essentially need a breakout board so soldering is easier than trying to solder to the SMD pads directly. Attached is a crude photoshop drawing of what I was thinking could work, but I'm open to suggestions. The in/out are holes through the board and the 5v and ground are pads on the back of the board. Attached is the data sheet for the particular LED. Also attached is the datasheet for this particular LED. Let me know if you have any questions.

...provide level shifting from v5 to 3.3v. I will fly-wire in the Altera CPLD in place of each IC, one at a time to verify the coding, starting with the GAL. U29 is a LS75, U31-32 are F139, U25-26 are F04. RP1-3 will be staying, and will ultimately be added to the SDRAM address lines, as I assume this is still current practice. The DRAM will be the last thing replaced. I am very skilled with soldering and these mods will not be an issue. A MIC5319 Micrel LDO will be added for 3.3v power. A TX0108 TI can be added should we find issues with the CPLD replacing the F04s. You can advise on current best practices. Note: Currently there is standard 15.6us CBR refresh support, however you can chose any refresh you desire for the RAM used. You will also be responsible for all in...
