The voltage I require is 12v in and 24v 50Hz out.
It is to trigger solinoids which require 8VA each. I have up to 24 Solinoids but I expect that no more that 6 would be on at anyone time.
Bluetooth
Try the blue-tooth wireless headset.
They are used with various mobile phones and also if you have a bluetooth adapter in your PC then you can use it there too, I believe.
Have you considered going to the local library and looking up some of the old radio-control model books? They have all that you need... ie. simple circuits which you will need to modify the power output of the transmitter and possibly change the frequency as desired.
libraries which don't...
35Mhz animal tracker
Hi again,
I just remembered about a friend of mine who was studying marsupials at Uni.
He had about 5 or 6 35Mhz animal trackers which allowed tracking by a portable receiever and antenna from almost a km away.
It was a purely analogue system. The unit was very small...
Interesting idea.
The problem however comes from when collars are removed, or if the pet is stolen.
Otherwise, if you were able to get in good with the mobile phone companies you might be able to do a triangulation of the pet.
Failling this there is always GPS, coupled with a electronic...
Hi everyone/anyone,
I am new to PIC's... Basically the project I am in need of building is requires these following building blocks:
# 24VAC generator to drive the/each solinoid (8VA rating on each solinoid)
# USB or NIC Interface PIC controller capable to dealing with 12 relays
#...
5V power supply work around
Why don't you pull the 5V line from a Computer power supply and place a 2A fuse to stop it drawing over 2A...
Otherwise pick up a USB Charger for the IPaq. that way you can plug straight into a USB Port when you replicate/save your data. Besides they are not...
Wouldn't it be easier to have a pulsating signal on the robot which pulses a signal at a regular interval? The receievers at the corner of the square detects the time and/or position of the pulse relays it back to the controller who can determine exactly where the robot is?
Then power can be...
Radio - ISOTOPE Batteries
Those batteries your refering to I believe that they are the same type that is on the Voyager I & Voyager II deep space probes.
Basically Solar cells coated with Radioactive waste sandwiched together to power the probe for perhaps up to 1000 yrs
