One of my favorite repositories of schematics is: http://costaricabeam.solarbotics.net/Circuits_Main.htm He has lots to choose from... enjoy ... -- Keith...
Excellent ideas, gentleman.. I can probably pull off something smart and nice looking with it all... Anyone have anything else? What's the consensus on the...
The sensor in Wilf's Improved Pummer is the solar cell. If you cover the solar cell or it gets dark, it starts pumming. As far as connecting the battery, the +...
Can you have a pummer with two LED or Phototransistor "eyes" like a bicore headbot or does one such sensor serve the purpose? Or two LEDs (phototransistors or...
With three toothbrush heads and a cellphone pager motor, xbox controller motor or motor with a weight on the shaft (such as a paper clip, rubber faucet washer...
This is probably a very basic thing I have missed but I need to ask. If I have a solar panel putting out 9v and I want it to trigger a transistor at a certain...
Soldering cellphone batteries: Must use flux and a very hot iron and do it fast. Have everything tinned first. Pummers: pretty easy and a fun project. The...
NICE work... any advice on soldering leads to the cellphone batteries??? I have several, in a box differant brands.. and really want to use them,, And I have...
I vote you make a 2DOF Head, those are really cool. That will probably be my next mission. Post about it on the beambotforums.com General BEAM Chat section,...
Hello all! I got a couple little solar cells- Open circuit voltage- .55vdc in the sun, Vmax 0.484V, Imax: 0.25-.0275 amps. Anyone have a good idea for these...
The battery isn't crooked. It is my poor photo skills showing! I only took me about two hours start to finish. Mainly because I knew how I wanted it to look...
Beautiful Pummer! That site shows some pretty good notes on the building of the pummer! Please post stuff like that on the beambotforums.com member bots...
I finished another pummer based on Wilf's Improved Pummer schematic. I actually recycled an earlier pummer and used the newer schematic. Check it out: ...
I am thinking that it is a lot more effient. It seems to keep the battery charged even in our low light winter months here in Alaska. I got the box finished...
Just posted a pic of a light-powered vibrabot in my (Jonjb's) Photo album. The motor comes from a salvaged Xbox controller. I know the bot works from holding...
It's great to see people building pummers(one of my favourite BEAM projects).I have never build one using this,improved,circuit though. Can somebody explain...
I just got the project page up for Wilf's Improved Pummer. You can see it here: http://akapplegarth.us/index.php?page=pummer-2 It is almost done. I am...
All PICAXE chips will run programs at voltages between 3 and 5.5V DC. However some computers may require a 4.5V to 5.5V PICAXE power supply to enable correct...
Does anyone know how low of a voltage you can efficiently run an 08M picaxe microcontroller at? I'm building a christmas lights type project with flashing...
No IC chip I could see. And no LEDs either. Looked like just the motor and battery. That's what i call keeping it simple. That's the way, aha aha I like it,...
YEP,, I saw them at ToyR us and they even have a track of sorts ,, mini inviroment for them to play in.. as far as I can tell, they are , just that, a britle...
Has anyone seen Hexbug Nano's(TM????). I've seen them carried at the local radio shack and sort of broke down and bought two! So much for ten bux apiece. These...
Well, I blew it. I missed it. By just over a week. Blame me, blame me... to darn busy getting ready for a trip to realize how quick things were happening. In...
