new project: solar rover based on Picaxe 18X

the idea is to use a picaxe 18X as a brain for a little solar rover.

i have discovered that a picaxe can function as a solar angine because it works down to 2.5 volt

so im planning to use a solarbotic 33x37 policristalline cell wich provide 6.3V - 30ma

picaxe remain in nap mode untill caps reach a voltage near to 3.5 v then activate motors to accomplish an action loop....

and so on....

i use a 74ac240 as motor drivers and geared pager motors ...

 

by the test i have done till now it seems all can work properly....

Cute Lego Felt Tip Printer

A friend forwarded this to me. Cool application of Lego to make a printer. The video author's comment on YouTube:

"Lego felt tip 110" printer connected to an Apple Mac.  This is not a kit you can buy and does not use MindStorms. I designed/built/coded it all from scratch including analog motor electronics, sensors and printer driver, the USB interface uses a "wiring" board.

Once again, this is not my work. I'm just posting something I found cool.

IF / OR Interrupt? Picaxe...

Hey guys,

I am playing with a 40x2 and the hintsetup and hserinsetup commands also with the flags commands... I would like to interrupt on either a hint signal OR a hserin input NOT both at the same time. It seems that with the various flags conditions, you can stack-up a bunch of stuff that has to be true to interrupt, but there is no "OR" --just a bunch of ANDS

 

Basically, "if hint1=1 and hint2=1 then inturrupt" but not "if hint1=1 OR hint2=1 then interrupt"...

Here is my first go around with Sketchup. I realize it SUCKS, but I can't figure out that dang rotate tool. My thought is that a rack gear would be moved by a servo … Read more
