HI Im trying to set up a simple data logger using 08m2 and DS18b20 set up like this https://picasaweb.google.com/113722269455296509901/InputCircuits#5135515315717431986 Using the code below sends the serial data(temp) back to programming editor ok but when I connect thru parallax to excel I...

thanks for all of this help, this image is the actual thing, except Ive added a capacitor across the 3v to iron out rattle in the 3v holder(seems to have fixed it, it was resetting randomly) so the interrupt code (setint %00001000, %00001000,c)just means of I pass the magnet across reed 2 it...

Thanks tried to attach file Im aiming to replace the reed switches with a hall effect, trying to use the same-ish code without having to set analogue parameters, for when I have a problem and I need the interrupt to reset using the magnet. thanks again Steve

Hi all I cant seem to establish which hall effect switch(not analogue sensor) is normally on. I bought some OH3144E Hall Effect switches but it turns out that they are normally off. Im building an 08m2 timer and have been using reed switches but want to try a switch. I have tried the analogue...

thanks the mosfet is the same one the original specified and seemed to work ok there, still thru an 08m2 only 6v on the drain side the motor says 200mA this is the original using 6v(and a speaker which I didn't use)

Hi I have a student project at year 7 making the same knock box discussed on the forum, also on instructables, but using 4.5v instead of 6v. A piezo responds to knocking, stores the count and the duration between, then controls a small motor with a weight to repeat the pattern. It functions...

attached the wiring space..and the torpedo(kontiki), not much room for more wires..sliding the batteries in is tight..and the timer has to fit in the tight side space... thanks for taking the time to think about this steve

thanks everyone I do have the pulldown resistor in ok, its drawn incorrecty sorry..(Visio has a mind of its own), and I also have the diode AFTER the relay + feed..and so glad you noticed Ive simplified to an 08m2..less space just different flash rates instead of 3 LEDs attached corrected...

Hi After several attempts and lots of guidance thru the forum I have an ongoing issue with timer for my kontiki(baitlauncer torpedo)resetting. It works fine until its under load in the water then cuts out randomly. To test I fitted and independent 3v CR2032 button cell to the timer side(theres...

ok thanks again..I must be closing in on something that looks right to a critical eye...I seem to have another 0.1uF capacitor close to the picaxe+ as suggested, and I presume this is as well as the one close to the regulator...I did have an IN4007 into the regulator but forgot to show it, but...

I dont think heat was the problem as I had the cutting out problem before... but waterproofing in the tight space is hard. I did not have the cutting out problem on a similar timer with a hall effect and no interrupt(so I couldnt turn it off) Ive added what I think is the snubber as suggested by...

thanks for the feedback Attached my first ever schematic, being the bricks and mortar type....so its not flash any help infinding why it cuts out is appreciated Steve

Hi I have a timer for the kontiki using 18m2, and two reed switches, built on a kiwipatch board. The timer activates an auto relay.One of the reeds is solely to interrupt at at any time, the other reed moves through three different timer settings, activating when the magnet is removed.. It is...

Hi I have set up 08m2 as a timer for the baitlauncher...works fine,magnet over the hall effect moves thru 3 stages and sets the timer at that stage when I remove the magnet..that bits works.. but I have a reed switch to interrupt so I can stop the thing if I need to ..but i cant interrupt...

Thanks srnet, I have added the voltage regulator circuit as I have it on the kiwipatch board, but not the download utensils, which are also in place, I will mess with the adcsetup command, essentially I want to: swipe a magnet to initiate a time period to count up to 3 magnet swipes if 1...
