I need someone to build a device that can be placed on a sidewalk to count pedestrian foot traffic and transmit the data wirelessly via email in an excel format. The device could use pressure or motion detection to register traffic (open to other possibilities as well, but motion detection would be ideal) I've come across existing hardware called Jeenodes that (I believe) could do this, but I don't have the technical know-how to build this. There's also another out-of-the-box device called Knut that is capable of wireless transmission of external data but foot traffic monitoring is not yet possible. An alternative to building this device from scratch would be to just build a foot traffic sensor and attach it to Knut's breakout board:   [obscured]  /manual/hardware/breakout-board/ Minimum requirements: 1. the device would need to be small and discreet and fit within housing no larger than 11cm wide x 17cm tall x 8cm deep. 2. If a motion detection system was used, it would need to...

What I need is very simple. I need a box about 10"x10". On the front of this box it will have two columns of LED lights (like the kind that's in a flashlight). The right column will be red, the left column will be white. There will be three judges so there needs to be 3 rows on each column of lights. From the back of the box will be the power supply and the 1/4 inch plugin for the top, middle and bottom lights and from these plugins needs to come a 3 way switch with a 20 ft cable. This switch will say white on left side and red on the right side. Everything needs to be labeled on the back of the box too. Also the box needs to be able to be mounted to a tripod stand or a mic stand. Its the same connection for either. The box needs to be light weight. Like 5 lbs or something. And this is VERY IMPORTANT, the lights should not light up individually, they should only come on after the 3rd person has made his choice of white or red light then the box will display all three judges ...

Hi i need a small multi LED pcb design. The smd pcb must contain: -8 rebel leds (different colors, 2x white) -2x 8-pin connectors The leds give their light in a 120 degree cone so no components (connectors/mounting screws, etc) should block the lighting. I would like the leds as close together as physically and thermally possible. The pcb must have a metal back for cooling the leds and also keep the pcb as small as physically possible. The schematic is simple, 1 pin of connector A goes to led 1 and from there to a pin of connector B I want to use 8 external led drivers to generate 8 currents, the leds simply use the given current via the connectors. If you think this doesn't work or can be improved in any way let me know. The current idea for the current drivers is the motien mdl24-3-600 For pdf see:   [obscured]  /media/186968/mdl24-30-600.pdf This is outside the scope of this project and may change later, i thought I just mention it. I want at least 2 mounting h...

You can build a circuit with arduino type. But it must be the smallest possible self after installation and costed the cheapest. I am open to the suggestion of design to make it more simple. the less expensive to manufacture and less weld. It ok for welding Surface mount Total dimension max +/- 3 in by 5 in Reads the voltage of the solar panel and depending on the output voltage it will set a time in minutes. High intensity 100% = 15 min. Intensity 20% min = 60 min and is proportional ratio when the intensity is between the maximum and minimum. Below +/- 20%. a message is displayed = Not efficient for this moment or what ever Push a bottom to activate the countdown and reset timer. On oled Display - time 0-60 min with the countdown. Display setup option Logo display in standby mode RED OR GREEN monochrome Size + / - 2 in x 2 in You can use a circuit board like arduino or micro arduino. Thank you !

I have a start-up company and am looking for someone who can develop a bluetooth wireless module that can pair the right headphone to the left headphone and to a device. The audio should be mono when only one headphone is connected and stereo when both. I am interested in building a functional prototype. The module should fit roughly within a 20x20x10mm cube including a power source for the module.

We need a simple PCB relay. The attached picture shows how the relay should work. The relay is quite simple. It's about the same as a laptop battery. It only does three things: 1: The system runs on the internal lithium-ion battery if the power supply is not plugged into an external 110vac/220vac power supply. 2: The system runs off the power supply if it is plugged into an external power supply. 3: The battery charger charges the battery when the battery is low and an external power source is detected. That's it. Here is a more extensive description by our electrical engineer. He has not designed a relay for power supplies before and that is why we're hiring you to do the work. His inexperience is your opportunity! "110V AC mains power is supplied to both the Meanwell power supply (which outputs 48 V DC at 4.5A) and the battery charger, which recharges a 48V DC 4.5A Li-ion battery. Both the power supply and the battery are wired to provide power to the LED, but only one sour...

Design the electronics for a plug-in timer. Create a small 120 volt 15 amp timer switch that can control anything that plugs into a wall outlet. Size small. 1" x 1" x1". Simple functions. One button. Turn on when you push the button. Turn off when you push the button the seconded time. The device will remember the time and repeat on a 24 hour bases. So if you push the button at 6 pm it will turn on and push the button again at 8 pm it will turn off. Everyday it will turn on at 6 pm and off at 8 pm. Hold the button for 3 seconds and it clear the settings. It should also be able to repeat turning on/off multiple times in a 24 hour cycle. NO LCD or display. Small and functional. Something like this attachment. Not sure if it should have a battery or not. Not sure the best construction. Looking for recommendations and cost effective solutions.

Need a very robust controller for a specialised dual hydraulic pump system. The twin piston pumps are designed to operate together to produce a steady, low flowrate (10cc/min) at high pressure (3000psi). The servos are STAR type 200 and the piston sensors are magnetostrictive. As one pump comes to the end of its stroke, the second one starts up to maintain constant flowrate. Maximum flowrate of about 8 litres per minute (at low pressure). We had a company provide micro-controller electronics, but they proved to be useless as they are very unstable and sensitive to power supply noise, causing us to have to re-flash the code periodically. Temperature should be 100degC for components. Space is very limited (35 x 80mm x 20mm) so system has to be compact.
