    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.

    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 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.

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.

    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.

    Microcontroller is considered as the backbone of Embedded System& it's most important feature is: "It can think".

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...
