Making schematics and layout by EAGLE. Hopefully in 6 business days. These are prototyping pictures   [obscured]  /file/d/0By3zumES05rsNGE5cFMzcHVvTmM/view?usp=sharing   [obscured]  /file/d/0By3zumES05rsZ0hKNUp6ZEoyd2M/view?usp=sharing As you can see in these pics, this is just intermediate board. No special components, no difficult wiring. I will prepare handwriting schematics and I want to ask you to make it as EAGLE data. I plan to ask tiny another intermediate board which has only 2-3 connectors as well (I didn't decide yet). I hope to ask this job fixed price at $800. I think it would be nice price even such easy task. However I want to ask working quick and flexibility rather than precision.

Hello friends how are you? My problem is this: I am using a PIC16F887 microcontroller to program with C CCS pic c compiler. I have two push bottom one for and one for RB5 RB4. When I press RB4 a green LED should flash for 7 seconds, after which it goes and lights a red LED. When I press a push botom to RB5, the red light goes off and a blue LED blinks for 7 seconds, after which the program is reset, ports and flags are cleaned to start a new cycle. It is very important that must be programmed in CCS C

Hi there, we have some sound effects created for our Bluetooth device. We are using the Nordic 51822 chip which is written in C. We are having difficulties integrating the WAV/MIDI file into the firmware. We need help with someone experience in working with embedded systems and able to convert the sound effects into a format that can be used in the Nordic firmware to play the sound. The device is small and therefore the speaker is limited to a more mono synth tone with frequency range of to 3800 Hz to 4200 Hz.

Survey Japanese Chemical Literature from about 1970 - 2000. Use Japanese databases, not Western databases. We already use Western databases like Inspec, Web of Science, etc. Search for articles with words : E7 and (d.o.p. .OR. "order parameter" .OR. "dye order parameter") We predict that the Japanese databases will show about 100 articles. We predict that the d.o.p. value reported in the articles will be too low for us to use the dye. We predict that most of the articles will describe custom synthesized dyes, dyes which will be too expensive. We predict that after looking at about 100 articles that you will find about 6-10 dyes that we can consider. To complete job, send us this an email with many dyes listed, with the d.o.p value and the C.A.S. number of the dye or a structural drawing of the dye.

Hi, I need you to source a company that can build me a custom VCSEL laser to meet the exact spec below. I cannot accept anything different from the below specs so please do not ask if something similar will work. I am looking to buy 500 - 1000 that meet the below specs for prototyping in July and then 250 000 - 300 000 for our first 1000 unit production run in Sept. of our new product line. This SMD VCSEL laser is not available as an off shelf product product so you will need to find a company who can build one to meet these specs. If you have no experience in sourcing or SMDs or VCSELs do not apply for this job as you will be wasting your time and mine. Target Price Per Piece in USD - $0.05 - $0.10 SPECS a. 5mW Output b. 680nm +/- 5 bandwidth c. undiffused beam and uncollimated d. Continuous wave e. Less than 1 degree Temperature Change during 20 minute continuous operation f. No coverings over laser - EX: Lens Cap g. 2.1V, 5mA input h. VCSELs ...

Short description: In this system, each table in the restaurant gets a battery powered wireless calling device with buttons. When pressed, this calling device sends a wireless zigbee or generic 2.4GHz message that will be received by one or more of the base stations of the system, which are based on Raspberry PI A+. The master base station memorizes the call status for each transmitter so that said information can later be polled over wifi and displayed by apps run in smartphones worn by the waiters. The apps for said smartphones are developed in a separate project ? you don't have to develop them. Deliverables for this project: ? For the calling device; scematics, PCB layout, MCU firmware ? For the Raspberry base station; software (including installer script that makes the software start upon boot) All software must be delivered with source code, and all source code must be professionally written and well documented in English. Suggested milestones (open to discussion before proje...

We are currently working on a PCB with a 3G module, ARM processor, DC/DC and some other parts. From time to time the 3G module or uC stop responding - the 3G module usually burns up and some of the pins of the uC burn as well. Although we have a great engineer working on the project, we'd like to have a fresh look from an experienced engineer that may think of something we've missed. We will of course give more information, the schematics are in Altium.

Hi, we want to use an IR sensor for a medical application (temperature between 25-45 C). We're interested only in the temperature change of the target (we're not interested in the absolute temperature itself). We would like to know whether there is any adaptation / optimization we can apply to the camera / readout circuit in order to improve its temperature difference accuracy? (compared to the usual case where the circuit is optimized to output absolute temperature, and then we derive the images, frame by frame, to obtain the change in temperature). I need you to support the solution with a reference and/or a calculation that would show the expected improvement in performance due to the optimization for temperature change (compared to the usual systems that are optimized for measuring absolute temperature). Best regards, Gil
