    I need a logo and an icon for a digital media production comp...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; a bear, bull, or 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 project...

    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.

    I have 20 off Monocrystalline solar panels each of 50 volts 7.5 Amp hrs and want to establish the best circuit diagram for the system. I also have an APC UPS Galaxy 3,500 which is 3 phase in and single phase out (240v) It also has a single phase bypass output. You should be an expert industrial electrical engineer as the grid needs to approve your design. Regards John

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...

    I need an over voltage protection circuit designed, which needs to cut off the input source when it reaches 59vdc. Max current of power circuit is 3amps. This is to protect the 12v and 5v power regulator circuits. During normal operation, the input source is between 40-59vdc. There are situations that arise where the input voltage may rise to 160vdc for about 3-4 seconds, hence the requirement of over voltage circuit to protect the regulators. The circuit must fit in an existing pcb design. Parts must be available in Jlcpcb. I want the circuit built and tested before payment
