I on this forum for only one reason only to share my info and build robots only ,not doing a writing class.

I will next time make my posts better.

I hope this ends it,so can back to the topic and post only about that topic ,notthing else.

Next item i add will be about my design and schematic and how to use it,and full parts list.

Still need to fix the circuit a little on the lamp circuit,and may be add a 220 volt design too.

Second circuit will be current monitor with script as another idea to monitor the battery.

It may take while since i have other projects too.

I'm just an old retired engineer from Bell Telephone Laboratories and really expect proper grammar and spelling when expressing technical thoughts and details. @robotmaker, I can tell that you have never had to create a technical document for publication or presentation to your peers or others. It is VERY difficult for me to read you information and glean any useful tidbits from the various threads you occupy. I like others have now gotten to where we just skip your posts. My old eyes cannot comprehend your words and the sentences you construct.

Still dont get it ,I WRITE VERY FAST and do not recheck my grammar or spelling ,i dont use it work ,may be you job does,plus i work at home for my job too.

Please we need to end this about my bad grammar.

THIS FORUM IS NOT ABOUT MY BAD GRAMMAR only about robot building,and so far only on this post does it come up alot. and i did over 2400 posts.

Why does it need to go on and on and on about it.

If i see more about it,will never reply to it ever.

LIKE i said i will fix some of my post so everyone can read it very easy.

Also this one and last couple ones no bad grammar or spelling

I only design and test circuits.if you need data i can put some together,but depends on data needed and why.

I woulder why this needs to go on and on about it,this post is about automatic battery charger docking not about other garbage from me and RICH

I saig again i will make my posts very clear ,even a child can understand it.

VERY LAST post ,i but i bet others will reply and keep it up and up

Ok i made some changes to my AC lamp circuit. Plus will explain it better too.

Connector J is a 2 pn connector pin 1 - is digital input from EZB Pin 2 -is gnd from ezb

R1- is 470 ohms it sets the current for led in UI optocoupler R2 - IS 47 OHMS it sets the gate turn-on current for the traic

Lamp is is a 120 volt lamp

LINE 1 is 120 volts hot is mostly dark or black ,sometimes red or if from switch it blue

LINE 2 is 120 volt neutral mostly white

PARTS LIST R1 -470 OHM 1/4 WATT R2 -47 OHM 1/2 WATT U1-MOC3011 OPTOCOUPLER TR1 -traic 2N6342

2N6342 LINK http://www.futurlec.com/Diodes/2N6342pr.shtml $1.43 EACH

MOC3011 LINK http://www.futurlec.com/cgi-bin/search/search.cgi $.55

total cost under $2.50 Will find my metal tiny box it fits in and post it

HOW my grammar now ,and can you understand it ,if not will add more info

I see tiny mistake LAMP has LINE 2 should be LINE 1

DJ please don't delete my thread. We have some great discussion going on here.

Now back on topic of auto docking...

Thank you for posting the circuit Fred it will be very useful to me.

Thank you Rich for supplying the code examples they will used in my auto docking project.

Here is a very interesting item from POLOLU that may be the key to getting this to work.

IR Beacon

IR Beacon User Guide

IR Beacon example

Rich could we adapt / re-write this code for the EZ-B?

sensors-list-used-in-robotic-projects

I only had a very quick look as I am off out but should already be out (yet couldn't help coming on here despite running late).

I'm sure we can do something with that though, if nothing else it shows how it works and a new script can be written to suit.

The IR beacon idea is one of the better ones in my opinion, it's silent and invisible and that's what I like.

It'll probably be late tomorrow or more likely to be Monday before I have a proper look at it but from what I see it looks like we can use it and base something from it.

Basically, as long as I know how it should work and what is needed I'm sure I can put the meat on the bones and get it working with EZB and ARC.

However, it would need a line of sight so getting in to the line of sight of the dock is still an obstacle to tackle... possibly use a few IR beacons to navigate around a house? We will see.

Nice find though, it'll come in very handy.

Using the Pololu ir sensor kit at present Its a two part kit as can be seen in demo .http://www.pololu.com/catalog/product/701 By placing one on the robot and one in your hand you can take the robot for a walk.

Should be possible to use as part of an indoor guidance sytem Pat
