howdy everyone [24 Aug 2004|04:00pm]

just showing my support for the BEAM community.

I saw the link to ROBOlympics and I'm wondering if any of you plan to be there next year. I was there in March and have already started building for 2005, it's going to be an interesting competition...

I have decided to begin sometime soonish (deending on how school goes) building a BEAM Walker. I ned to get my hands on some servo's or cheap gear motors (any suggestions, and im talking CHEAP). I have everything else. I was reading my junkbots book and i dead under the optional parts.

"5x Bicore process indicating LEDs. Blinky lights are always necessary on a robot--didn't you ever watch an science fiction movies?"

Hopefully it will work out. I have been dreaming of having a walker since i first saw Tilden on television so many years ago. w00t w00t.

Hi there! [30 Nov 2003|12:04am]

I see there are only 3 people here (counting me now) but I thought I might wander by and say hi.

I've been doing beam things for about 6 months now. Granted, I'm trying to clean the rust off my brain from years of disuse so my electronics skills are a little dull. Anyhow, I recently made a beam style blinker based on this schematic. It looks like this:

Basically the battery is two small 1.5V watch batteries taped together and slide into the open space below the LEDs, positive side up. It was extremely difficult to solder the square to hold up the battery, but it works.

Because im a sample FREAK and i need a 12-step program i ordered more stuff from ON Semi:

15x 74HCT4066
50x PN2907
50x BC547
50x BC557
25x PN2222
20x 74HC244
20x 74HC14
20x 74HC14
15x 74HC244
18x 74HC244

and for the most part i made sure i ordered the PDIP packaging of the parts. I guess im starting to get the mindset that the worst that can happen is they stop sending me parts. I've ordered qute a few more Maxim and i got the voltage triggers from Telcom-semi.com.

I started organizing the parts into top opening containers. It makes it much easier to access them. My physics teacher is kinda getting excited about this too.

My friend kleets is starting to get into beam robots, and of course, he is jumping on the sample bandwagon. Im trying to avoid spreading my sample sources too far out (though im probably the last to know) because i dont need these sources cut off.

Interesting BEAM e-mailsCollapse )

who wah, found a replacement for the 1381. http://samples.microchip.com its a TC54VC and then the numbers after is indicate its voltage trip level. the bonus, you can get 3 pieces of 5 seperate voltage trigger levels. so 15 of them for free. which rocks. I ordered them. in the TO-92 package the pin out is the same as the 1381 too, so they are identical kinda.

http://costaricabeam.solarbotics.net/Circuits_Main.htm GREAT SITE ON CIRCUITS! I found a 555 timer photovore. its the simpelest one there. other than the 74HC240 one, you need two LDRs (check) a 555timer chip (check) and motors... it helps to have a solar engine, which isnt hard to fasion if you have the 1381 chip. I NEED IT!

caution on ordering some of those parts... they are SMT parts... REALLY SMALL!

[25 Sep 2003|04:38pm]

just ordered... the "bicore" chip from Texas Instruments. They are overnight UPS air mailing it to my house. How awesome is that.... and its all free..... WHOW!!!

free samples of electronic parts is like candy... for nerds...

[25 Sep 2003|04:37pm]

whoo whah! ok, you saw the videos and the pictures, now i needs your helps. im looking for a part made by panasonic. its a 1381 (1380 series) voltage trigger, prefereably a H-M rating, but maybe even an S trigger. I would be forever indebted to the person who finds a site where i can order samples of them... Maxim makes a counterpart eqivalent i guess MAX8212... but i want the 1381.... if you have any luck let me know.....

i have over 200 free parts commming in within the next week because i ordered samples from websites and its r0x0r.

i feel like such a cheap ass... i just ordered a shit load of samples from http://www.onsemi.com including the 2N3904/2N3906 transistors and a few of the optical buffer chips. its somewhat exciting, though i feel really cheap, but thats ok, because im a student, paying off a car, who just got laid off, and is thinking of going to college in the near future. i cant find samples of the MN1381 voltage trigger tho.... any ideas?

Turmet LIVES! Its not the pohotopopper which i failed at constructing last nite, rathre its jus a servo motor with a very long flagella that looks pretty damned cool. it has ZERO function. but its cool. i plan on searching for photodiodes for the photopopper sometime soon.

not that many people frequent this community (me included) but i got my robot parts in today. andy pang rocks. all i have to say is everything is a lot smaller than i originally thought. like the solar cells are just slightly larger than a quarter and the motors, wow, the only smaller i have seen are in those mini remote controlled cars. its kinda cool. but overwhelming at the same time. im gonna try and get pictures as i go so look forward to that.

[ mood | excited ]

Well my order was processed. Currently in the mail for me is

4x Panasonic 2422 Solar Panes. 4.15 voltas and 7mA. 24mm x 22mm @$1.89 each
4x pager motors: without the excentric weight. 1.3V. 75mA. @2.00 each
10x + 1x free 5mm Flashing green LED. FLED @$0.4 each
10x + 1x free Panasonic 1381J Voltage Triggers @0.68 each

With shipping it comes to $32.36. I think i will find myself ordering more parts from Andy Pang sometime in the near future. Especially more powerful solarcells for walking robots.

Andy Pangs Website: http://home.ust.hk/~bcandyp/solar-kit.html

I would reccomend anyone looking to find the elusive 1381 Voltage Trigger look into that because its the cheapest place to find it. Solarbotics.net has them for $1.75 each or $1.40 if you buy 10 or more. Andy's are $0.68 each and one free for every 10 you order. Kinda spiffy.

When these parts get here, i plan on constructing the basic photovore, a modified photovore1 and possibly a pummer or water robot.

1modified photovore will have the photodiodes in the front and back, thus making the robot take a one sided bias towards the edge of the light pool. The basic photovore has the photodiodes in the front and back making it charge for the center of the light pool, and having two or three charge for the center can get hairy.

I also think i want to make a one motor turbot, however it seems as though i might have to order a 7xx240 chip from solarbotics for $1 each. Not too bad, but more than i really want to. Well, in all technicality i can just use a miller solar engine to power it but the bicore would be the most efficient. I also will get some for stacking in a 2-motor walker.

dandywilber has protested me building these stating that they creep her out. I think she's kidding, but i think it would be fun to drop one of the walkers on her bed whilst she is sleeping. I know its sick fun and she'd probably kill the robot and me but it might be worth it sometime down the road.

Also on andy pangs website are a few tutorials. Most of the tutorials are made to specifically accompany his kits which you can order too. However if you have the parts it'd be more than worth it to look into it.

I hope to build some of these things and show them to my AP Physics Teacher. I had him last year for physics and i showed him "junk bots bug bots and bots on wheels" which is the most awesome book i have ever paid full price for. Normally im a thrifty shopper and i get $150 linux books for $2 or $6. I paid full price ($25) for this book and it was worth every cent. I also reccomend looking into that if anyone here gets serious about BEAM.

Alright, i've been doing a lot of research on BEAM botics lately. I plan on making some robots for school projects and get my Physics teacher interested in them. He already was when i showed him "Junkbots Bug Bots and Bots on Wheels" but i think once i show him some working bots he might "fund" future adventures into the BEAM realm. Im not trying to use him, but he's "in the know" when it comes to abstract electronics parts and the such, so whoo.

I have plans to make some PCB's for these robots, and i plan to once i get somethings going on it and make some actually work. The PCBs will be invaluable in creating different behaviod patterns of similar robots, which will be more than worth it in the long run. And they also add to that A in B.E.A.M.

Im kinda excited because i think tomorrow im going to order parts for these things. Im saddened tho because the shelf (a 4' by 2' shelf extending from the back of my headboard) was going to be used for robots, and have my own Robot Jurassic Park (RJP) with specialized lighting and everything, but now it houses my Iguana, he was outgrowing his 60 gallon aquarium and now he has a 5.5' x 4.2' x 2' plexi and metal screening cage which will have all kinda of things and hiding places. Anywho, im going to have to construct a super cool RJP tripple tiered that will live in the corner of my room and have ramps to the other floors for those able bodied robots. aka. the walkers and super powered photovores.

Supplier Tip #1 [11 Aug 2003|07:30am]

Andy's Light-Seeking Robots Surplus Robot Kits is an excelent source for robot parts including the elusive 1381 Voltage trigger ($0.68) and relatively cheap ($2 with weight removed) pager motors. Unfortunately it seems as though it wont last long because he is just a consumer who bought surplus, not a commercial site.
