The video recorder is probally not fitted with a freeview Tuner. The tv is fitted vith an integrated freeview tuner and it is this that is alowing you to view Freeview channels. your only hope of recordeing freeview with this setup is if the TV has a video out connector that will alow you to record ...

Kurt From a quick look at the circuit you may need to look at the common mode voltage that is present when useing high side monitoring . your 50mV is sitting on top of the 14V from the battery you need to either have the monitoring circuit floating with respect to the main battery or you could consi...

howabout using a Vdrive http://www.vinculum.com/prd_vdrive1.html to interface to a memory stick and something like a armmite http://www.coridiumcorp.com/ to interface to the gps. The V drive alows you to open a file on the memory stick and write data to it you can then plug it back into a Pc and rea...

in general most people select a processor that they are happy with in your suggested board if you are happy with the processor and beleve it is up to the job you wish your robot to do then go with it. From looking at the web site it is not clear what software is supplied and as you are expected to o...

after a quick look at the interface board i think the easiest way to measure current is to use the A/CTE series CT that output a o to 5V Dc voltage based on the current. To read this into the interface board i think that you will need to use a Dallas D" 2450 IC that has 4 A/D input channels. th...

with a 3 to 4 week time scale you may need to considering purchaseing off the shelf data acquisation hardware and spent the time with getting the software working check out national instruments www.ni.com They specalise in data acquisation cards for PC's most cards will handel 16 analogue inputs and...

The following suggestion may need some though as it may inpari the safety of the system. if you can determin what current is normally flowing in the switch / relay contacts and it is of a meaningfull level (several hundred miliamps) how about putting very low value fuses in parallell with each of th...

Can you provide some more information as to the type of signal you are decodeing

will the signal be at a constant bit rate ?

will the data to be received start wilh a known start pattern ?


this will help with possable solutions.

just got my ARMmite ordered when i first read this thread it fitted a requirement that just came up. Haveing played withit for a couple of days now the list of potential uses for this board is growing this includes tepreture logger and an intelegent Nimh battery charger. my only consern with it is d...

why not adjust the thermostat on the HW tank a few degrees higher
when the showers are taken to get tha same temp the hot water will be mixed with more cold water to get the correct tempreture thus the fixed capacity of the HW tank will last longer.

you may want to consider MP3 players chips

have a look at the following

http://194.201.138.187/epages/Store.sto ... cts/SPE020

it is MP3 module that uses a compact flash card to hold the sound files and can be controled using a pic

the HP E1410A is a VXI instrument it can be controled from a normal PC but you will need a lot of additional hardware to do this VXI instruments were developed for high end automated test systems that required a lot of different instruments all connected to a computer what they came up with is a mod...

Assuming the supply is a fixed voltage then the resistor value sets the current through all of the LED's so if you set the resistor value for 4mA so with one led on then that led will get 4mA if 2 led's are on each will get 2mA (assuming identical LED's) and 1ma if 4 LED are on. which will cause the...

firstaly what accuracy do you whis the position to be detected ? my first thought is to attach an optical mouse sencor to the bottom of the rod. this will detect the movement over the base board. it will not provide actual position but reletive movement and speed form this allelleration can be calcu...
