Building a unique funtioning organ/synthesizer that will be used in an upcoming film. Need banks of oscillators designed and built/manufactured. The instrument has 52 keys, each key needs three oscillators summed together into a dedicated output as each note is sent to a separate speaker. Looking to have the circuit designed with three oscillators, frequency and level control for each and summed into a single output. This job posting is for the circuit design and PCB layout, Any leads on having the final circuit assembled or manufactured are welcome as well(we need 52 of them). There are addition jobs for this project if this first one goes well. Thanks.
Hi there, We need someone to design us a simple circuit that includes a timer, an illumination LED that turns on/off with the timer, a temperature sensor, and an indicator LED to indicate temperature alerts. The project includes the following tasks: - Design the circuit and BOM - Build a couple prototypes for testing - Once proven functional, provide documentation and design files (e.g. Gerber) for the circuit. If this interests you, please share any examples of other similar circuits you've designed. We'll then send you a more detailed statement of work, and specification for you to create a quote for the project as a whole. This will be a work-for-hire arrangement under a written independent contractor agreement, to be signed separately from the [url removed, login to view] agreements.
Need to to design and implement a greenhouse controller to keep temperature and relative humidity (RH) around set levels. The PLC receives signals from wired temp/RH sensors and accordingly ON/OFF exhaust fans and evaporative cooling pumps or hot water circulation pumps. System description is available.
Ultimate Hacking Keyboard is an open-source, split USB keyboard designed for extreme productivity and ergonomics. I’m László Monda, founder of the UHK, and you’ll be working with me. I’ve written about 90% of the UHK firmware, but I don’t have enough time for it anymore, so I’m looking for a developer to maintain the firmware in the long run. We’re using GitHub extensively. The firmware is released under the General Public License v3, and your contributions will be publicly visible. You’re welcome to check out the UHK firmware repo at [url removed, login to view] to see the code and the open issues. You’re expected to: * have a good understanding of ARM programming in general and USB HID in particular * be self-motivated and able to resolve issues on your own without extensive management * write clean code and follow our coding standards Experience with Freescale/NXP Kinetis MCUs and Kinetis Design Studio / MCUXpresso IDE would be highly appreciated. Please contact me, and include your relevant experience, skills, and your hourly rate. I’d also like to see the source code you’ve written in the past. Looking forward to work with you! - Laci
For the second board, we can start with the first. -We can remove all of the external power (12-14v) and power these components from the Arduino 5v (it might be smart to power the sensors from the 5v pins next to D22/23) -Keep the 5 screw terminals for the ds18b20 sensors -Keep 2 thermistor terminals (2 screws) -Keep 2 of the 5v-Gnd-Data sensors (6 screws total) -Keep 2 interrupts (2 screws) -Keep 2 voltage dividers -Keep 1 extra 5v and 1 extra Gnd screw terminals -19 total screw terminals all to be placed on the Power/Analog side of the Arduino Shield -Keep all of the connections for the Neo-6m, LSM303, and 2x HC-05 chips as they are wired in PCM1. -Add a header for a 20x4 LCD connection. (image attached- I am using this wiring) -Add three buttons that will trigger page changes and other inputs on the LCD (5v, Gnd, and connect each to any unused Data pin through resistors) -Add a 5k potentiometer in the LCD wiring as shown above
i need a design that incoperates a lipo chager with headers that will accept a huzza esp board and a socket that will accept a 18650 powercell togeter with a switch and a connector on a small footprint.
we have esp 32 . proximity sensor, ultrasonic sensor, bme280, voc sensor, 4 relays, lux sensor. all to be controlled by esp32 which transfers all data to our app. we want to use mongoose os for security and Mqtt. most sensors have mongoose os library but few do not and would need to be imported from audrino and wrapped in mongoose os wrapper
buy electronics online from USA and ship to my address out side USA

Hi we are a start up Company. We want to develop a Universal Car Immobilizer that can be used in place of the original car remote in case you lose one of the original car remote. Our aim is to have this universal remote rather than people buy specific remotes for makes and models. So how it works is you bring the original remote and our remote together to the locksmith, put the original remote in their decoder machine and once the code is in, put our remote in the machine to encode the codes into our product. Once done, our product would work the same way as the original remote and communicate with the car. We need help with the PCB development and the type of IC Chip to use. Thank you.
The concept is about taking data from e drum pad via Bluetooth through arduino and save stats onto mobile device . Arduino Part is done and app GUI animation is done i am attaching the files which is hand written i want a freelancer developer preferably a female from north India with decent attitude and can we available for me Bugdet is fixed and just a matter of 2 days work
Small Project, I require a BOM (Bill of materials) list for my pcb camera. I have Gerber file, i got a offer to do it for $10 but he is unavailable so the price is not high, if you just want quick so cash inquire me.
我们是买家,想从中国上海，北京等大城市寻找工业使用的 inkjet printer card。中国有很多生产工业inkjet card的制造商， 希望您能帮忙买一些 工业使用的inkjet card 样品,以及相关的中文或者英文软件。 我们想要买一些能运行 Xaar 128 inkjet print head 或者Xaar 384 inkjet print head 或者 RicohGen inkjet print head的 printer cards。Fujifilm Dimatix (Spectre, Polaris) 我们也需要能用在普通电脑， 连接 print head connector card 和print head 的PCI Card。 如果你有找到一些相关的carriage board 会更好，在操作上有时也会需要这个。 一般来说那些相关的软件是免费提供的。 我们也需要Generic Cards， 因为我们是ink生产家，所有买回来的这些电路板都是用来测试我们所研发的ink。 这些电路板主要是用在普通的电脑系统去测试 ink和Xaar以及Ricoh printheads 的兼容性。 我们并不需要买电脑， ink supply card，ink level card， servo card， rip station，encoder等等的。。 我们希望您能： （1）通过邮件发给我以上所述电路板的相关的广告，数据，用途（Datasheets）或者相关的链接。 （2）发给我上述运行电路板相关的一些软件 （3）发一些上述相关软件的广告，名称，用途（Datasheets）或者一些提供参考相关的链接。 （4）寄给我 电脑的PCI card 和一些小型的print head connector card， 或者是连接这些电路板的其他线路和电路板。 我会在Freelancer付咨询和服务费给你或者你的代理人，但是对于上述的相关的cards， 我们会直接从相关公司购买。 如下图可供参考，我们希望能在2018 买到更多上述的电路板以及和您长期合作。 请问你能解答这个问题吗？为什么在2017年使用的是PCI 1.0？ 非常感谢您宝贵的时间
