Battery recharger 12v projectmunkák

Hi there, My name is Nada and I need to create a wireless (battery operated/chargeable) water resistant/proof homeware product. I will disclose more about the product once there will be a disclosure agreement between all involved parties. Best regards, Nada Al-Bader

I require a circuit that detects the presence of water when 2 probe wires are submerged. The dimensions of the circuit board should be 54.5mm x 21.5mm The circuit should operate at both 9v and 12v The LED should only illuminate when the resistance between 2 probe wires falls below 10kOhm The power, LED and probe wires will be connected by XH 2.54 connectors: Power is to be supplied by an XH2.54 connector with the polarity in the image provided The LED is to be connected by an XH2.54 connector (polarity independent) The probe wires are to be connected by an xh2.54 connector The surface mounted XH2.54 connectors should be orientated vertically (as pictured) so that the surface of the board can be coated in resin to waterproof it.

...send me a link so I can purchase and deliver to you. Also provide a small one paragraph on how you intend to connect these together. 2nd milestone: Wire together the hand controller to the controller board and deomonstrate 3 indipendent motor control (can use a single cheep motor on 3 different channels) and toggling of 5 acessories (could just be LED for now) 3rd milestone Wire in a Lithium battery and three high-quality motors that I will send you. Demonstrate full current draw from the three motors (testing to make sure the currentl will not cook the boards and motors). 4th milestone Turn on/off camera via controller and activate sensors that are wired to the motor controller board. There are other milestone that will be defined later such as integrating video and data upl...

We need a logo for a podcast called "Ergs & Equilibrium" which is an interview-style podcast discussing recent papers in energy and environmental economics. It just needs to be a relatively simple/minimalist logo that has the name of the podcast and a simple design. We would prefer if it were more general and not just a picture of a lightbulb, battery, lightning bolt, etcetera. Essentially no general "energy" or "electricity" clipart-style designs if possible!

We have a DIY home emergency power system that consists of...consists of an outdoor portable mini gas generator (prob size of a toaster oven <30 pounds) and an indoor Li-ion battery/inverter (prob size of microwave oven <40 pounds) connected by a 50’-100’ heavy power cord. To excite some corporate partners, we would love to flash a slide of an “artist’s concept” of the system that doesn’t look like the products that are already in the market. It doesn’t have to be too accurate and doesn’t have to have 100% of the features. I sort of like the attached visual (not sure what is really does). It would be cool if the 2 component boxes were about the same size so that the generator that stays outside can be like a ruggedized airport wh...

Hi all. I am trying to measure a complex shape to create a 12v panel for a cavity in my car. I have already made a panel from trial and error, however, I would like for this panel to be exact and I am looking for a way to do so. Currently, I am thinking that maybe using lidar and the canvas app on the iPhone could be the way to go? And then to convert this scan to a measurement which could, in turn, be transformed into a stencil that I can cut out from wood. Please see attached the photos and let me know of any questions. Thanks!

i am looking for a an all-in-one developer to assist with the coding and PCB design of a V2 prototype for my project. The prototype utilises environmental sensors and sends information to a mobile application (currently using thingspeak - web page). i have been working on a project to develop a environmental sensor that monitors multiple gasses as well as humidity and temperature. these sensors are controlled by a minicontroller that periodically takes readings and relays those readings wirelessly to the my thingspeak channel (ideally this would be a mobile application). As well as taking readings, the module will also send push notifications (currently achieved through thingtweet) to my mobile phone when thresholds are crossed. the module also has Red,Yellow,Green LED'...

...have it mimic a heart beat, the first motor will pulse the the second motor will follow it. All the while the RGB lights will be changing colours smoothly while also pulsing. I have a battery and connecter so I would like for the device to be able to charge it and also run on its own. I am not sure if the parts will run smoothly together so I would like someone experienced and willing to do revisions and spend time on exactly what I need. I have added links to all the parts I have. Please do not waste your time thinking it will be a simple project or try bidding higher or wasting my time. Thank you. The project is 60 dollars..

Could you write a blog about why having a battery powered wine opener is better than a charging one? Like its better to remove clutter on a counter and stuff.

Hello Freelancers, I am looking for two logos for my automotive/auto repair business. I own an automotive repair company that does oil changes, tire rotations, battery tests, diagnostics, and all kinds of automotive work. At our shop, we can pretty much meet everyone's automotive needs. The name of the company is LikeWoah Automotive and our color scheme is a blue/white/grey concept. Though, if the artist decides that a different color scheme would go well with this industry and our logo, we are open to a different color scheme. Please create me a very nice, modern, and appealing logo that is automotive/auto repair themed and will grab anyone's attention and bring a customer to our shop. If you want, you can also make it Texas-themed as this is a company in Texas, USA. I...

The input power is from uk mains 230V AC, which needs to be step-down to various DC supplies ranging from 12V to 5V in order to power multiple devices that can be controlled by an Arduino. I have attached an excel document that shows details about each of the devices for reference.

We are an existing Powersports company that sells Gas powered motorcycles, ATVs, watercraft boats, and such. The picture is of our current location. We are opening up a new location which will be all-electric, primarily surfboards, and electric bicycles. We want a new sign that we can do a color printing on vinyl. The premise of this new location is that everything is electric battery-powered and they are all fun products. This sign will be in front of our new location. the dimensions will be 12 ft wide X 4 ft high. We want a cold electric vibe while encompassing our current company signage font styling

Windows Search is not searching within the content of my documents (doc, docx and pdf). I have made sure that these extensions are included in the index. I've also made sure that battery saving is off. Also, the file locations that I want are selected. There's an "indexing is off" message. And there's also 140k files "pending" in the indexing settings. Also. If there's a better Windows application for indexing and searching the contents of ARABIC documents, please do advise. Thank you

I'm looking for a simulation model solution. I have two simulation models, the first model is complete and it's designed for PV integration with battery storage to control the primary frequency and inertia of the power grid. I need to integrate DFIG wind power instead of PV and also change the energy storage system with a Hydrogen fuel cell. The second one has missed some files, so I need this one to run and add a hydrogen fuel cell as energy storage. Once we'll agree then I'll share my simulation models with you.

Looking to build a simple smart weighing scale. Features required are - - Device should be small - shape & size of a coaster (circular, but not very thick) - Should be cheap to make & easy to replicate - prototype can be around $10 - $15, but if it needs to be mass manufactured, we would need to do it around $3 - $4 - Device should be battery powered (flexible on battery capacity, based on cost) - ideally rechargeable battery - Maximum weight expected would be 1 - 2kg - Require precision of 1g - Device should have a button, which when pressed sends the weight data - Device sends data to a web API / via Bluetooth (either is fine)
