Hello, I need to upgrade all my PCB SW and FreeCPB looks OK for me (even though it forces me to stay on ms-windows). However it's only an element in the tool chain, so what free software can work (interactively if possible) with FreePCB ? I've been using an old EAGLE (the "gratis" version) too long and it does not fit my growing needs anymore... thank you for your help, yg -- http...

Hi all, having an IPAQ 4150 with a defect backlight only, I wonder if there is a schematic flowing around. I would like to see if there is a inverter for backlight that could maybe being damaged. Any Help would be appreciated. Best Regards Markus

Hi Group, Shouldn't pin 4 on the jtag header (labeled AREF) go to Vcc? http://www.olimex.com/dev/images/avr-m16-sch.gif Matt Meerian

Has anyone out there ever fixed a Mitutoyo Hardmatic HH140 hardness tester? The display shows "busy" forever. Its supposed to show busy for a few seconds, then "0.0" I checked all the easy stuff- no broken wires, connectors, but without a schematic, I'm stuffed. Any suggestions from someone who's been there? thanks -- Bill Chernoff in Canada

Hi All, After I upgraded some network I end-up in my stock with some boards. I have more then 150 of them. I have to clean up my back office and I feel guilty to throw it away. But I have no choice. It is very neat board. I designed few projects, which working fine for me. It is not top of line board, but for someone it may be good. I have schematic diagram for it, which will explain you e...

I would like to build my own programmer for Microchip PICs. There are many schematics on the Internet available but I can't seem to find exactly what I want. What I would like is something that provides all (or most) of the following functions: * Can program PIC18 family of devices (or all of the major PIC families if possible) * In-circuit programming (not debugging): the electronics us...

Since I have to do a largish schematic and won't be in the office the whole time I wanted to connect my trusty old trackball to a laptop. This old mouse still boasts a, gasp, 9-pin serial connector. But you know how it is, when you get used to a tool no matter how ancient you don't want to miss it. Just as I still miss that wonderful Fahrvergnuegen of my first car... Tried it on two l...

Hello, I would like to know if someone can point me in the right direction. I'm looking for a schematic that would allow me to send and receive data over the power lines in a house. I did a search on google under the following and did not find anything, I could use as a starting point: Signaling over powerline circuits, bpsk circuit, and binary phase-shift keying circuit. Thank you in advanc...

What is the best FREE Schematic & PCB Layout software available that will run on Windoze XP? I've looked at PCB123.com and Expresspcb.com and they have pretty good programs available. Unfortunately if I use either one I'm stuck getting the prototypes through them. (Because they won't output Gerbers) I've also looked at Eagle Layout at cadsoft.de, but the size limitation of 100 x 80mm on ...

Hello everyone, We are just starting off here and need a little advice, It seems that as far as a GNU debugger programmer for ARM9 is concerned the OpenOCD system is the way to go, for this you need a DLC5 Jtag cable or equivalent, How slow is the DLC5 Jtag cable in practise, is it usable or will it frustrate me? Does any one have a Gerber file or a eagle board layout/Schematic for a ...

I'm attempting to interface a CMOS camera module [C328-7640] to my PC via the RS232 com1 port to learn how to interface with the chip. The modem cable is working ( I tested it by connecting the Tx & Rx pins (2& 3) then opened hyperterminal and when I type any letters they get written on the terminal ) I put both the schematic and how the breadboard is wired on my website to show what I d...

I just picked up a demo board from TI. Its been around awhile, but I can not seem to hunt sown the schematics. Its the round PCB with a MSP430FG439 processor and an LCD display. The silkscreen says: "MSP430 Watch and Altimeter". Does anyone know where to find the schematic for this board ? Thanks Donald

Hi, In my work, especially the one related to my teaching and hobyyist activity I always prefer using the Open Source environment. Therefore KiCad is may favorite schematic and PCB tool. Unfortunately, this tools sometimes doas not provide all needed part symbols and models, so it necessary, that either me or my students have to create them ourselves. (Well, I know, there are website...

Id like to design a simple board over the holidays, I've never layed out a board before, so Im a little nervous :) I've started the schematic capture, and the routing and found a cheap place to get it fabd.
