Hey again, I was just going through these parts again, and found two MC1489P line-drivers. I read the datasheet and found that each NAND's hysteresis can be...
I was looking for more parts on a port driver card from that old computer again, and I found maybe the coolest IC ever! It's called the 74LS240N, and it's...
I suppose it's time for me to participate a bit.. Or just ask a question. My beam fun has been limited due to unemployment.. Anyone hiring in st pete, fl? :) ...
Alright, so after my last bout of fun with walkers, the crawler <https://sites.google.com/site/nakazoto/robot-rapture/my-robots/crazy-so92; lar-1> , I decided...
Hey BEAMer's(I'm figuring out what this rich text editor's all about, as you can see), Here I was not long ago, tearing apart 20-30 yr old computer remnants in...
Hey, BEAMers. I just got accepted into this email list, and wanted to make a good first impression. I love robots. They're pretty much all I think about all...
Howdy all! For my next project, I'm kind of in a mental pickle, haha. I have two signals coming out of my NV net. I would like to invert one of the signals...
I came across this circuit online: http://robobugs.solarbotics.net/Dangerbot.html First of all is there a difference between red and green FLED's other than...
Howdy all! So, I've got another walker planned but before I get on with the fun part of building the thing, I really wanted to wrap my head around nv/nu cores....
Hello all! This would be my first post, so I figured it would best be spent introducing myself! (It should be noted that I'm new to this whole Yahoo Groups...
And that is the one where there no messages at all in a month.So,I39;m wondering what everybody is up to.I hope it is being busy building BEAM projects.Let39;s...
Hey everybody! I'm just getting involved with the wonderful BEAM bots. The problem is that here in Germany I don't get some of the transistors and I have to...
Well I have been experimenting with the Miller Solar Engine circuit. I hooked one up to a 3.7 volt Li-Ion battery and it seems to have actually charged it to...
Hello everyone, My name is Michael and I've been working on a Fred Photopopper from Ray's FLED Fred Photopopper tutorial online and I was hoping for some help...
Hi there, My son and I are brand new to electronics and have set up the Symet circuit on a breadboard that works well with 1 or 2 AA batteries, but does not...
And a happy Wilf Day to you too! For those of you new to BEAM, this marks seven years from the day of Wilf's first post to the BEAM community. Thanks again,...
Ok guys, i know this is not really a beam topic so i apologize pre-hand. You guys are the most intelligent people in the field of electronics that i know...
Well met, BEAMers! I'm joining up with a local Steampunk group and would like to know if anyone has had any experience designing circuits with tubes instead of...
Don't know if I have posted these links here, if so it was a looonge time ago. Please have a look at my light following head, it's different :) thanks, Jim ...
Hi all, Because I couldn't find it anywhere else, here's an LTspice model for a grounded bicore. Note that the power supply needs to be the PULSE type...
ok guys i need some help. i have several nixie tubes i scraped that i want to use in a clock application. The nixie's are NEC LD8051. I can not find a data...
Hi everyone! I haven't been active on here for quite some time, and during that time I have become an internet guru. I have bunches of full dedicated servers...
Theo Jensen's Strandbeest has been well discussed in this group. I see he now has kits available, for those wanting to play with Jensen's wind-powered walkers....
Have y'all seen this contest? It's a sort of "back to our roots; lets see what you can do with basic logic chips" sort of contest, leveraging on the success...
