Prakash's Blog: Very Usefull links for ROBOT builder

Hello Everyone,

Here i am posting some of the important links that i came across before few days, related to robot building,
These links help u too much, just try each related link.

1. Electronics

1.1. General electronics sites

A collection of tutorials in electronics subjects. Well worth a look.

http://www.designnotes.com/designschool.htm

A huge collection of links to other electronics sites, nicely indexed.

http://www.epanorama.net/

Another excellent large collection of links to electronics and software sites.

http://www.pin-outs.com/directory/

A large resource of articles written by industry insiders, field service engineers, and semiconductor company engineers on a wide variety of electronics subjects.

http://www.chipcenter.com/kc/

A personal page by an electronics enthusiast. Very entertaining stuff, as well as informative.

http://www.electricstuff.co.uk/

A circuit theory textbook online

http://www.sweethaven.com/acee/forms/toc01.htm

HVW Tech have many documents on a variety of electronics & robotics subjects on their site

http://www.hvwtech.com/downloads.htm
http://www.hvwtech.com/learning.htm

Excellent optics resource and community

http://www.optics.net

Excellent electronics resource and community

http://www.electronicsee.com

1.2. Electronics circuit archives

These sites offer archives of circuit diagrams. Most should be tested, but this is by no means guaranteed!

Electro Tech Online
Electro tech offers a great resource for discussing General Electronics, Electronic Projects, Robitics Chat and PIC/BASIC Programming. Electro Tech also offers Free Electronic Projects and Theory Articles.

1.3. Chip information

http://www.equinox-tech.com/chipdir/c/a.htm
http://www.chipcenter.com/circuitcellar/
http://www.bonex.co.uk/startpages/framed/home.htm

1.4. Electronics company information

http://www.epanorama.net/companies.html
http://www.nctnico.cistron.nl/all_man.htm

1.5. PCB layout and manufacture

Eagle Layout Editor - The best free PCB design tool on the web. Superb. Free version is restricted to 10cm x 8cm size and no more than double sided but that still allows very complicated projects. Features schematic capture, extensive libraries, very good ripup-and-retry autorouter, user groups, extensive array of online public domain tools available for it.

http://www.cadsoft.de/

PCB Pool - Very good value PCB production house. For example, a double sided 10cm x 8cm PCB designed using Eagle above cost just £24 for a one-off including all P&P costs. Based in Ireland. Very helpful on the phone.

http://www.pcbpool.com/

ExpressPCB - A free PCB layout tool, with optional online manufacturing ordering (from USA). Cheap even though they come from the USA.

http://www.expresspcb.com/

PROTEUS Lite - A shareware PCB layout package. Better than ExpressPCB but no tied manufacturing service.

Proteus Lite at download.cnet.com

An excellent description of how to make your own PCBs. I did this stuff for 4 years and came to exactly the same conclusions as Mike has here. Making PCBs really isn't very hard these days now that most people have a PC which can run free layout software, and have a good printer that can print dark black onto transparencies.

Another guide to making PCBs

http://www.geocities.com/SiliconValley/3569/data/pcb2.htm

A method of building prototype circuits without making PCBs (and not using the dreaded Veroboard!). I'm not totally convinced by this method, personally I think it is always worth making a PCB. Using the techniques described in the links above, making PCBs is really quite easy.

http://www.chipcenter.com/circuitcellar/december00/c1200sb1.htm

An article describing the effects bad PCB layout can have, particularly on analogue circuits. Essential reading if you are building your own speed controller!

http://www.chipcenter.com/analog/c060.htm
