| RS232 4 digits serial led module in cascade (6 hours ago) | |||
| Dear Sirs,We need something like this : http://www.siliconcraft.net/SC4DLITE-SERIAL%20LED%20MODULE.htmWe need a cascade of 4 digits Seven Segment LED Serial Display. We need a line of 50 modules, and I have to be able to send to each module a number through my computer RS232 port.To understand, I have 50 different products in my warehouse, each product in one box, all 50 boxes are in line. When I have a order, I want to display the number of items the operator has to pick up of each Full details | |||
| USB Digital IO Board + Windows control GUI (11 hours ago) | |||
| Create a digital IO board, connected to a PC via USB. The board is driven by an on screen GUI. Tick boxes control output channels and the analog voltage is displayed onscreen. The analog input can be switched between an output connector and a trim pot resistor by the use of a jumper. Board must contain the following. x5 Digital output 0-5V x1 Digital outputs open drain or open collector x4 Digital input x1 Analog input 0-5V Power supply driven via USB bus.

| strain sensor and associated electronics (22 hours ago) | |||
| Hello,My name is Vadim. I am developing a device which I have invented and need the help of an EE.The device needs to take readings from a strain gauge at an interval around 60 Hz, display them on a screen (perhaps a two digit, 7-segment LCD) and then, upon a buttonpress retain the last measurement upon the screen until the button is depressed again.Further, there needs to be a way to fine tune the relationship between the numbers on display and the output of the strain gauge to acco Full details | |||
| Level Gage (23 hours ago) | |||
| Hello, We intend to use an ultrasonic sensor to measure the liquid level of a container, the sensor has a nominal frequency of 40khz with a detection range up to 3m. The heigth of the container will be diferent and it could go from 0.50 up to 2 meters. We want to use a PIC and the chossen family should be conservative priced. The range should be adjustable to adapt the measurement of diferent container sizes, outputs will be 5 leds that will indicate 5- Full, 4- 3/4, 3- 1/2, 2- 1/4 & Full details | |||
| alarm-using 555 ic chip-normally closed-alarm on break (1 day ago) | |||
| Purpose of the project:I need an alarm to protect metal covers (which are rarely opened) they open downward or outward depending on the cabinet) Our problem is theft of components inside the cabinets and a need to set off an alarm if the cover is opened. We do not want to use reed (magnetic) switches because the cabinets are rarely opened and there is considerable vibration and heat as well as exposure to the elements. Reed switches would require too many more parts for Full details | |||
