Hello I need an expert in SPICE software for circuit design. Please apply if you have the required expertise.
We require a PCB designer to layout a PCB for us. The test circuit has been developed on an STM32 Nucleo-144 MCU Development Board, NUCLEO-F767ZI. You will be required to draw the full circuit based on the development board and then after approval, layout the PCB in accordance with the circuit diagram. PLEASE READ THE ATTACHED DOCUMENT. IF YOU DON'T READ I WILL DELETE YOUR BID.
There is something wrong on my site. I installed Google's GDPR Compliance plugin but I don't know if I set something wrong. The banner ads from the Netmediaclick circuit are showing up noticeably late and I don't understand why. I'm looking for an expert on GDPR and banner ads, I don't want freelancers who need too much time to detect the problem. My site is and the one in the picture is the banner that is showing the most delayed of all. It doesn't just have to come up on the homepage. As a plugin for banner ads I use Ad Inserter.

To build a weather station using esp8266 nodemcu model.. that forecast weather like temperature humidity rain air pressure using dht11 and bmp180 and one rain sensor and the will be shown in web server or any third party apps like blynk or thingspeak all u need to do is design a circuit and write the code for it... I know it is available in YouTube but I just want a neat code... That's all
I need a logo and an icon for a digital media ...channels like Youtube, Instagram, Twitter, Tiktok, etc, as well as for websites. Broadcast will also be available, but less common. The logo should project a modern almost futuristic, powerful image, focused on technology as we will be located in Silicon Valley and most of our clients will be technology companies. Perhaps sort of Cyberpunk. I like the idea of utilizing imagery of electricity and circuit boards, but am also open to the use of perhaps animal imagery; I think I'd like the head of an elephant. I'd like to avoid bright colors as primaries and stick to black while using the other colors as secondary or tertiary colors. I am also open to the use of an aperture image or a power icon. I will also require the pr...
I need a circuit diagram that fulfils the following conditions: 1) It must be controllable via a program (it doesn't matter if there are already open source programs for this or if I have to create one myself - it just must not work via a mechanical operation). 2) All products in the circuit diagram must be purchasable in Germany. 3) All exact products must be declared (e.g. controller Designation). These are the exact specifications: The circuit diagram is to be drawn within the white box (see attachment). 1: Can be connected to 10 or 19. Vmax: +/- 40V Current: +/- 120mA One wire. 2: Can be connected to 9 or 18. Vmax: +/- 40V Current: +/- 120mA One wire. 3: Can be connected to 10 or 19.

If you are an expert in using Coolspice and know a lot about MOSFET circuits, please directly send me a message ASAP
... We are interested to build one based on Western Chips (eg: TI, ST .....) with good documentation and test data. Your responsibilities: 1. Find the best chip for the purpose 2. Designing the boardcoil.... 3. Assist us with finding the PCB manufacturer who can provide all components and ship the final product. (We do not want a design that could NOT be manufactured) The design is very straight forward and could be based on the best practices and example circuit provided in the chip's data sheet. The only matter to note is: in our product 2x Qi receiver modules will be used. The output of these are directly connected. In case only 1x is active or both are active at the same time, these module should Not damage each other. Output voltage: 5v Output Power: &g...

Bayfield Learning is an online tutoring and learning company. We offer K-12 tutoring across all subjects, test prep (e.g. SAT, ACT, GED, GRE, etc), English as a Second Language...a symbol of learning. However this is a digital brand so a book might not be the best representation. A possibility is a lighthouse which evokes helpfulness and providing direction. On the other hand a lighthouse is a bit old school and can also evoke strong intimidating feelings. A light to lead the way is a possibility. Also maybe something to evoke a modern, digital approach such as a circuit. Maybe a screen / monitor. Maybe a Play button. Desired color is something like royal blue. We want it to evoke feelings of helpfulness and maturity (i.e. not baby blue) while not creating a feeling of int...

I’m looking forward to design a robust AC input filter for HiLink AC DC converter in which an AVR project is running. And I would like to add some prime features like inrush current protection, AC line transients / spike protection as well as inductive load back EMF protection which may sometimes reset the microcontroller. Please note we have only phase and neutral, so earth connection for the filter circuit. Please find the attached file of the proposed project.

Hello. I need a circuit and pcb designed. It is for automotive applications so will need to run off 12v but be able to handle spikes of up to 15v. The circuit will be trigger by a reed switch and active an LED. Both the reed switch and led wont be mounted on the PCB. The pcb will need to be a 55mm circle with two cutouts. I can send 3d file of the placement area. I would also like a second design made that functions the same but has Bluetooth that can talk to a phone for signalling
I would like to build custom R/C cars of different sizes (1:32 scale, 1:16 scale, etc.). The car will have a chassis, 4 wheels, motors, R/C circuit and electro-magnets to pull another dye-cast car (without a motor) along with it as shown in the video. The cars should be able to make left/right turns, move in forward and backward directions, climb and descent slopes (15 - 20 degree angle) together without loosing their coupling. The dye-cast car above the surface can be any off-the-shelf standard hot-wheels or matchbox (1:32 or 1:16) toy cars. I will bear expenses for all the parts and shipping that would be needed for completion of this project, the bidder should bid only their service costs. The project will be marked as complete once I see the prototype demo and the prototype is s...

We'd like to create a logo for a new product range that we are launching. The product range is electronics based (technical customers) and is called "Lemon IoT" ecosystem. We're after a simple logo that we can use in our branding but also will be on our Printed Circuit Boards (PCB), so will need to be simple. We expect a "lemon" to be in the logo.
Hi there, My name is Harsha, I am trying to build a project which involves driving 3 stepper motors inputs using raspberry pi 4. The problem is the entire circuit is supposed to be compact. Drivers used can be drv8825/ a4988/ trinamic TMC2208. The steppers are supposed to run smooth. Thank you, Harsha

Microcontroller is considered as the backbone of Embedded System& it's most important feature is: "It can think". A Microcontroller looks like a simple electronics chip, but in actual its too powerful (also called Embedded Computer) because its programmable. Using programming code, we can control all I/O pins of a...multiple functions. Before microcontrollers, DLD gates were used to create logics i.e. adding delays, turning signals ON/OFF etc. DLD is still in practice for small projects but if you are working on big industrial projects, then DLD circuits become too messy & thus too difficult to handle. In below figure, I have added two circuits of traffic signal lights: Left Circuit: 555 Timer is used for creating the LED sequences. Right Circuit: Micro...
