I am looking for an electronic designer to enhance and complement a ready-made PSB design. Likewise, I require the design of a plastic casing to protect the circuit, with the necessary holes to make physical connections. The electronic circuit consists of: • A source of energy. That is, an input for one or two 3.3v lithium ion batteries (as more or less current is required), with their respective space in the housing. • A switch with its respective hole in the housing to turn the circuit on or off. • System for recharging lithium ion batteries, with its respective hole in the housing to connect a USB cable. This system must also have a led that indicates that the battery is already charged. • Boost type DC-DC voltage booster, which raises th...

Hello, I am an Kevin, an engineer based in the UK. I am designing an amplifier that is powered by a PC power supply (12V DC). PC power supplies generate a lot of electrical noise so I want someone to design a device that eliminates the noise so that no hissing, cracking etc can be heard on the amplifier i.e. CLEAN DC. The device must be cheap to make and use PCB mount components. Thanks.

The Real Batman Chronology Project is a study of serialized storytelling in superhero comics. More specifically, the Real Batman Chronology Project tracks the narrative continuity of DC Comics via the lens of Batman, plotting each of his appearances into detailed timelines. To most folks, simple questions arise: “Doesn’t one just read the comics in the order they are published? Why does there need to be a project dedicated to ordering comics? If it is so difficult to figure out a reading order, surely there must be a lot of similar projects online, right?” Ultimately, we get to the bigger question: “Why is my site necessary?” These questions (which I will answer, don’t worry!) speak to something broader than just Batman (we’ll get to Batman...
I volunteer with a DC-based not-for-profit that works with Ethiopian officials and citizens to improve the lives of orphans in Ethiopia through advocacy, education, and the financial support of agencies and individuals fighting the orphan crisis on the ground.

I am seeking a research writer who can prepare a 3-5 page report answering that question and including the additional points included in the attachment.
I have what I THINK will be a simple project... I want to create a WiFi-enabled controller for a process I’m currently doing semi-manually. It involves several things, but the more complicated stuff/code has (I think?) already been done... I currently have an Arduino that is operating a turn table (via a DC motor), triggered by a load sensor (ie, a kitchen scale), and guided by hall sensors (ie, tells it where to start and stop when initiated). All of that code has been written and the process is functional and operational. It just needs to be translated to both a physical display screen, and into a WiFi module. I’m thinking about using the Blynk app as the base? It seems to have all the capabilities I need but every time I try to start making it I get lost!!! ...

Attached you will find an infographic that demonstrates the difference between a standard AC battery system on the market and our iLubat (DC battery system). The bottom line is that our DC system is very interesting because of its very easy installation procedure and the fact that one does not have to install an additional inverter for the battery. We would like to put all this into a clear animation video that is between 30 and 60 seconds long. Please use the infographic as a guideline for creating the video.

I am doing my project on integration of PV system and battery with single phase power grid . I have already designed the converters with controllers (dc/dc boost converter on PV side, dc/dc bidirectional buck- boost converter and dc /ac converter with PLL on grid side ). So i still need to integrate all converters with power management control ( i want the system to charge the battery when the PV generate power more than the power required to the grid , and discharge the battery to supply the grid PV when the PV doesn't generate enough power as required to grid).

Hi Mykola S., I noticed your profile and would like to discuss a project that would involve a battery powered device using dc motor and a few sensors or switches. To discuss it I'll need about an hour of your time for which I'd pay you so that you can judge for yourself if it's something you'd like to work on. Importantly this project would most likely require access to a bolt rifle (preferred 0.22LR caliber) Best Lukasz
