    Hi, I need a ready-to-use image file for Raspberry Pi Zero that will do the following: - fast-boot into a Sega Genesis emulator; - use buttons connected to GPIO pins as a game controller (4 directional buttons - up/down/left/right, and 8 functional buttons - a/b/c/x/y/z/start/mode); - no text/raspberry logos on boot; - show preloaded games list on start-up that lets you choose which game ROM to play; - output audio through a sound amp to a speaker; I don't know what to connect amp input to, so I'll need a diagram. - himi disabled (if necessary), AV output only. I need a ready image file that can be deployed directly and will work right out of the box without tweaking anything. Pinout of the buttons can be on any GPIO pins but make sure to do the corresponding settings in an emulator. Also, a simple schematic that shows GPIO mapping is required. I will need your video of everything working before I release the milestone. Serious bidders only please. Experience in making Rpi projects is welcome. Resources that might help you to accomplish this: 1. Remove boot-up text: [login to view URL] 2. Fast booting: [login to view URL]

    Adapt PCB from Eagle to KiCAD and increase performance from current 80A to 200A with peaks of 400A (specify heatsink for the design). Theoretically, used MOSFETs (FDMT80080DC, two in parallel) should be capable to handle 200A requested currents if they are cooled properly, but heatsink must be calculated. Also the Würth press-fit elements are already capable to handle 200A in theory. Probably it would be more safe to redesign the board for more MOSFETs in parallel. In addition to that, the board should be produced with thicker copper plating, currently only done 70µm.

    Dear Sir/Madam For unique project, we need to design our own composite to HDMI bridge converter. its going to be a part in a big electronic PCB, therefore we look for a design/drawings/layout cosiderations/software interface from someone who already did that or know that well. its a good "stand alone" task, so we found that fits to www.freelacer.com. it can be done by 2 parts digitize the analog signal than use HDMI transmitter or by single chip. Please consider the HDCP / HDMI adopters cost, (which we try to get an exemption) Thanks

    Our current PCB is designed to control four strings of addressable Leds over WiFi using a NodeMCU ESP8266 V2. Works well, but could be better with a few changes. --- Revisions --- - It uses a logic level shifter to connect the 3.3 V ESP data ports to 5 V Leds. We found that there are two sizes of shifters and it is difficult to know what you will get when ordering. A second set of pin holes 2.54 mm WIDER would accommodate both sizes. {See pictures} - Using the same approach of having an alternate set of pin holes, the PCB should accommodate either a V2 or the wider V3 NodeMCU ESP8266. - The pin order on the Led terminal mounts is currently data, ground and then 5V. {D,Gnd,V} To match the order on a standard strip of Leds the order needs to be ground, data in the middle, and then 5V. {Gnd,D,V} - The board should fit into this box: [login to view URL] -currently 61x69 mm -new PCB dimension 95x55 mm - Assembling the PCB for the box will require mounting the terminals inward, or with sufficient clearance from the side. Holes will be cut for wires and DC barrel jack. - The DC barrel jack will be moved 1.5mm closer to the edge so that it is almost flush when in the box. - The back of the board has [login to view URL] (CAPS) in solder. This should be [login to view URL], still in solder. FRED will remain as it is (or larger) in solder on the top where it will not be covered by components. - Wider solder lines from the power source to the Led terminals. - The screen print will continue to have the same information it does now. -The screen print will have FRED printed in big block letters under the ESP chip. - The screen print will have [login to view URL] printed at 25mm or larger anywhere it fits. - Not critical. The terminal data ports are not in sequence when mapped to the ESP. (1,6,5,2) Changing them to 1,2,5,6 would be nice. That's everything.

    I need a circuit designed for a Raspberry Pi that contains the following: Voltage regulator receiving +12V DC input and outputs +5V DC. The +5V DC will power a Raspberry Pi and should contain a UPS circuit using either battery power or capacitors (preferred). Upon +12V DC loss, the battery should power the Raspberry Pi for ~5 minutes and a signal should be sent to the Raspberry Pi over either an SPI or I2C interface to shutdown the Raspberry Pi. Within the same circuit, I'd also like to power an AV amplifier/distributor. The circuit should take one RCA input (Video, Left Audio, Right Audio) and have 4 outputs.
