Hello, We are looking for a router that can work in ad hoc and infrastructure mode together. It will create two wireless networks. One mesh network to connect to other wireless routers and another network to connect mobile devices to the internet. Each router should boost/extend the signal. Not sure which one is the best (5 Ghz or 2.4 Ghz) but the system should operate within the ISM 863-870 MHz range Europe and other. More details in private message. Thanks MAGUIDO

I am looking for someone to add a very simple ADC function to my current working code. here is an idea on my current code i have a circuit that has an analog op amp circuit which is responsible of applying a ratio to an input signal via dividing resistors, and i have 16 pos rotary switch controlling 16 optocoupler to control which resistor is selected so the ratio can be different, now all what i need is some one that can add a working ADC so that it can control when the optocoupler is opened and when is closed based on the input voltage. i forget to mention that code i have is been made on CoIDE i need this adc code ready in 48 hours maximum. please Bid with a reasonable amount thanks

Looking for a 12V DC motor control for a small 100W motor. Need a CPLD with LCD or LED Display The Display can indicate 2 Digit Count that shows time that allows motor to run for a specified time. Say Display =01 implies 15 seconds Display = 02 implies 30 seconds etc., Need a up count button and down count button to chose the correct value. Components needed : 1. Small 2 digit LED/LCD Display, 2. 100W DC motor, 3.110V to 12V Power Adapter, 4. Up button (can be simple push button) 5. Down button 6. CPLD You can breadboard it and I will get a PCB designed once the system is working. Get back to me for more specific details

I have a custom PCB based around the Freescale i.MX6 that needs to have simulation done on its DDR3 interface. Depending on how that goes there could be follow on with the eMMC and PCIe interfaces being simulated. Must be done in Altium and then the files passed back because we need to run the simulation in house on our Altium installation. The design files will not be allowed outside of the United States.

Need a circuit than can track a pencil or similar type line as a device moves along it and sends signals to two or four stepper/servo motors or other position controllers to keep the device in line by compensating for any drift within 6 mm (or more). The device consists of an inner and outer frame. The outer frame is for large movement. The inner frame is for precision movement. The outer frame moves horizontally, parallel to the line and is not electronically controlled. The inner frame holds the tracking unit. It is the tracking unit that adjusts while the outer frame is moving. If the outer frame begins to move out of the range of the inner tracking unit, an indicator comes on indicating the direction to move the outer range otherwise the inner frame adjusts automatically to maintain position. The inner unit can move via the servo motors or similar position controllers +/- 3 mm. This is the minimum acceptable range. Greater range is desired. Summary: Device tracks along a line Co...

I want a laser trip wire PCB to be designed it should have a laser beam and LDR, When the laser beam is disturbed it must trigger an alarm, it must have out puts where the siren and lights in the house can be connected and one more thing is once the laser is tripped siren and lights must be on for 1 min. the circuit board must contain all the component in one board. it must be easy to produce, reliable and cheap i have attached a link for your reference but in the link the siren goes off once the disturbance stops. our board should keep the siren on for at least one minute   [obscured]  /watch?v=1HZQHcWTlOA&noredirect=1

REQUIREMENTS (also see the attachment) 1. We have a small table surface of 4 inch by 2 inch in L & B, and 1-2 cms in thickness 2. When a ball hits/thrown on the 'in -zone', GREEN LED should be lit on the long extended unit (metal). If the ball hits in between the in-zone and the out-zone, AMBER LED should be lit. If the ball hits anywhere outside of the 'in-zone' RED LED should lit. 3. The data captured should be sent via Bluetooth to a smartphone app (the app will indicate where EXACTLY ON THE SURFACE did the ball hit. (the unit will only show different colored LED to indicate hit or miss) 4. Operated by removable coin cell battery, preferably in the extended unit Sensors (and other units/PCB) can be placed INSIDE the table surface or as an attachment BEHIND the surface table (we would like it ideally inside the table) 5. The ball hitting the surface could be made of leather, rubber or resin. All no metallic 6. The unit will be coin battery operated - no exception 7. No ex...

I am looking to get a power distribution board made. It will be 3-4 layers and will have 12v input from top layer pad and distribute power to multiple pads across the board. I need 1 plane for 12v power, 1 plane for ground and top/bottom layers will have solder pads. There might also be layer for other trace connections depending on requirements for thickness of the board. There are 4 areas where I need 12v/GND pad on top layer to solder directly onto. The board I am looking for will be similar to this:   [obscured]  /forums/attachments/5/5/4/8/3/1/a7414440-197-pdbzmrrev5comp1.jpg But will not require all pads, it will be more simple. I can provide board size, measurements and hole locations. The board needs to be at least 1.6mm thick and have pads labelled for easy construction. Top layer will have text/logo that I will provide. Please tell me if there is any more information required.
