I do not want to highjack another thread , but would like to hear some group comments on selection of microcontrollers for projects. After reading some comments here I feel it is a time to ditch my

A battery powered radio will be a lot cheaper. There are some inverters that claim to be pure sine wave here: http://www.donrowe.com/inverters/puresine.html About $650 ought to cover it for a 2 kW

RS-422 (single TX, multiple RX) or RS-485 (multiple TX & RX). Balanced lines are much better than RS-232 though I have used RS-232 for decades. Other balanced line technologies could work. Network

Thanks gentlemen for the good suggestions. I think the 2 co Latching relay is the simplest solution : 5 Volt Relay, Latching, 2 Form C (DPDT) From $0.86 / each from an internet merchant 'Memo

would like to get a true sine wave inverter 1.5 - 2 kw that is clean enough to power AM radio been reading on web but haven't found a total solution any recommendations?

Hello John, M ore information on IO-Warrior-56 and companion products. See: http://www.saelig.com/category/MFR00093.htm The IO-Warrior24 device is a USB 1.1 device, has 16 I/O pins and comes in a 24

I am a little confused with what you trying to accomplish. Do you want to control devices (lights, relays etc.) from your PC? Are these devicces, or some of them, input devices to your controller -

Hi John, I've done something remotely similar to what you're trying to do using an Atmel ATMega8 (now getting obsolete- but more recent replacements will work). I bought myself a USB<->RS232 cable and

The closest thing I've seen to what you need is a TLC5947. Single chip, needs just a current-setting resistor, etc. Unfortunately they can only drive strings up to 30V (with a 5V supply). Maybe you

Hi Sanmeet, I uploaded a typical simple solution to drive many LEDs in series with a constant current. Hope it helps. "HV-LEDconstantCurrent.asc.pdf" Kerim

Great suggestions so far. I was hoping for a complete board. For the moment I just want a working PC I/O device. With an easy way to attach all of the wires. I am going to worry about the the rest of

Im looking for a LED string current balancing IC without success. Does anyone knows of such an IC and point me to the same or some manufacturer who might be manufacturing such an IC? Requirement: I

You may want to consider an IO-Warrior-56-Mod. See: http://www.saelig.com/product/IC2006.htm It doesn't meet all of your requirements. But it does have 50 I/O lines, Linux software support and only a

It's never been sold there - something to do with patents, perhaps. Leon -- Leon Heller G1HSM
