Heya Dominico, Thanks, I know that already, the problem is both of the capacitor's legs are the same length as it was scavenged from a board a while ago. I was...
Hi praetorius, I've seen on Internet that there are several case for these caps. If the shape is a "drop" shape you are not lucky but if it is a cylinder,...
Couldn't you just measure the volts in the cap,then hook it up to a battery,and then measure again after awhile and see if it's gone up? regards,Arno...
I was thinking of doing just that, but the cap is a tantalum electrolytic [usually low voltage], and I am not sure what the working voltage is, don't want to...
Tantalum capacitors are, like aluminium electrolytics, sensitive to reverse polarisation. Also they tend to hold charge regardless of polarisation, although...
I found the best way is to slip a knife in the join up the end where the keyring is attached, and flex the plastic apart. It's glued, but will pop off if you...
I've just got mine and I cracked mine open by removing the keychain loop (very weak metal, easy to bend). Then I stuck a watchmaker screwdriver into the end...
I would like to make a large version of a solar engine, replace the capacitor with a 6 or 12vdc lead acid battery, using a larger solar panel, etc. Other than...
Hey, they cost $1 total.. what do you expect :P I had one of the one's I bought lose an LED, but it turned out that the solder had delaminated from the circuit...
I picked up a few LED flashlights a couple of weeks ago because they were dirt cheap and had a nice aluminium body which I wanted to use for something else....
I built a Pummer on my breadboard from this schematic http://www.beam-wiki.org/w/images/c/c9/SE_D1.gif but It's not working. I'm using a Flashing LED as the...
You can place the solar panels in series ( positive to neg to positive...chain them) until you get the needed voltage. Series = Add voltage, Parallel (positive...
Well, not quite... Using Wilf's water bucket/solar engine analogy, you are filling a bucket (capacitor) with a hose (solar cell), until the bucket is full and...
Good analogy.. The panel in these keychains work well for magbot circuits as they don't seem to need much at all. I think they'd be fine in some pummer...
Its the motors for sure. I think I'll just forget the microcore and try sequencing the biped with a picaxe I have lying around. To: beam@yahoogroups.com From:...
Oh yeah, probably and surely are the motors itself. Try different ones. Happy building. ...Harold. On Wed, Jun 10, 2009 at 7:15 AM, caleb pearson < ... Oh...
Hey everyone - I had seen the RU2420 on sale at Electronics Goldmine but just missed them still having any in stock. Does anyone know of somewhere I can get...
Does anyone know of a solar powered pummer that is able to fade in and out? so once the first Cap charges and it becomes night time I would like the pummer to...
