Don't think you need to worry about your neck. I'm a little worried it will just rock side to side. But on the other hand if it moves very slowly (thus ...
Hey, i was making a tutorial site but it didn't work out. I spent a few days making a schematic database which i'd really hate to see to go to waste. It's...
Bookmarked. That database is pretty impressive. Not too heavy on the BEAM stuff however but there sure is a lot of info there on general hobby electronics....
The FLED SE is a form of the SCR circuit with the positive feedback loop closed through the resistor. The FLED SE is triggered through the FLED which sets the...
Hi Dave, Welcome to BEAM! I'm sure Wilf won't mind, my putting my 2 cents in. As said, the main benefit of the FLED SE is the availibilty of the parts. Like...
Thanks Myc. Even I understood that! If I add another solar cell (5.5V), to my symet will it be more efficient in lower light, or is the lack of interest...
Hi Doug, Adding another solar cell doesn't help the SE's "efficiency" but rather helps "fill" the capacitor bucket (using wilf's water analogy) more quickly. ...
Thanks for that Myc and as always everyone is welcome to ask questions and/or contribute. These transfusions of ideas and information are the lifeblood of our...
Hello, I think I know the answer to this but I wanted to check. I've got a sunceram 2433 solar cell and a 1381G (2.4V trigger). When I build my SE the voltage...
So my first thought upon reading this -- is that a fet opamp as a quasi comparator + schmitt +? would be ideal to play with trigger points etc. Would still...
No probs Dave. You carry on. I think my problem is more or less solved anyway. I understood most of what wilf said in the last message, but "fet opamp as a ...
The SCR SE is a circuit that can be made to work but must be finetuned to the solar cell, light level and motor. As such it is not suitable for applications...
Even if it has been done I'm always ready to do a new and improved version. There have been many opamp and comparator beam projects but only few SE type. One...
Does the FLED in the FLED SE need exposure to some light to work? The reason I ask is I've just covered mine with black tape to stop the thing locking up in...
Hi Gareth, First, when measuring a solar cell's output, open circuit means when you have the solar cell not connected to anything. You put the solar cell ...
No, the internal FLED circuit that times the flashes, is designed to work in the dark. However light impinging on the internal circuit lowers the threshold at...
Wilf I'll tell you that the next time the sun comes out, which isn't going to be today by the look of it! Doug ________________________________ From:...
I didn't realise all the robot links were broken. I deleted them all and started again, i've got 40-50 robot (mostly BEAM) links on there. Over 500 schematics...
Thanks Peter! Definitely in the top ten best collections of electronic circuits and projects I have come across. I hope you will continue to maintain it or...
