I have been doing a bit of research on the Unicore circuit and more complex Nv networks. A large part of the work is in understanding the technology and the...
Hello Everybody, It may not be flash (yet) but I have my first website up for the world to see. it's at: http://ausbeam.solarbotics.net many thanks must go to...
Hi all, I am a new member of ground so I would like to say Hi to all of you from Denmark. By the way, I am working on Modular Robotic System using LEGO DUPLO ...
The Next Step in Toy Robot Evolution "The secret of RoboSapiens is a philosophy called BEAM, or Biology, Electronics, Aesthetics, and Mechanics. Essentially...
Hi, I've been thinking about type 3 SEs and charging rates and current of caps. Say I have two identical caps charging in parallel through 2 different...
I'm going to make an order for some parts for BEAM experiments. Could someone give me a list of the most popular resistors and small value capacitors they use...
I have a gm from Solarbotics, the small one, and super glue got on the gears. now it doesn't work, but it gives me a idea. The gm is small and just the metal...
Hello! I think Im ready to tackle the challenge of building a solarpowered head, but I was wondering what schematic to use? Ive seen the ones wilf posted in...
Hi, I don't quite understand when you would use a FET in place of a transistor. For example, some Miller SEs use a FET instead of the transistor. What are the...
I put together a laser driver for my projector idea, but the scope traces seem to be coming up short. (they aren't as crisp) The circuit is little more then a...
I have built a 5-motor walker based upon Walkman and currently the circuitry is completely free-formed. I designed a circuit board for the walker in eagle, i...
G'day, everyone. As Wolfgang requested, here are some thoughts on the mechanics of RoboSapiens. A special note of thanks to Ori and Wolfgang for offering to...
hey all, I was cpomparing prices in my different electronic store catalouges and I came up with two different descriptions for the same 74hc240. Which one...
I just started building a lathe yesterday. and started a new page to document it. my short term goal is to make small pieces of metal out of large pieces of...
Among the many caps, resistors and other useful bits and pieces I have recovered from various PCBs, I have two components with the following markings: The...
Hi, This is a repost from the beamrobotics group. I just found out that that group isn't really active anymore. I am new to BEAM. So far I've built a couple of...
I'm trying to figure out the negatives to using a 74ac240. I know the ac240 provides a better current for driving motors then the hc240. Why sholdn't I alwasy...
i had to "borrow" my roomate's boom box IR reciever, and some stuff off on some robots, but i tried that circuit out with LED's. the only way i could get it to...
Hello all, new member here. I hate to be one to ask such a general question, but being new to robotics, where should I begin? What should I read? What should I...
would it be possible to use a solar head that would look for sun, and when the light is found, the head would focus a lens (the lens is bigger than the solar...
Tom Gray mentioned using IR instead of touch sensors on his bot, and i'm sure he was just talking about the switches for the IMX reverser (which is also in the...
I've downloaded expressPCB for a bit of playing around, but I'm a little confused. I can't find a 74ac240-style chip in the components list. The closest I've...
Good morning guys, durring my long weekend, i built the walker from the junkbots book, it still needs some tuning but it basicly does what it is ment to. i was...
... The Maxim 8212 is at the heart of the PM3 Solar Engine (my personal favorite). Adi recently noted that the MAX6375-MAX6380 can be used as a replacement for...
Hi, As promised, I put up an initial version of a 1381 replacement list. You can see it here: http://beamagination.solarbotics.net/1381Replacements.php Note...
I have removed the xplanation.doc file as it contained a virus - w97n/marker.gen For those who have downloaded this file and have not cleaned the virus, I...
