The peeps on PR did start calling it the heartbeat of the case.. :)
There was so much that could have been done with it... but as they say ... hind sight is 20.20 hehe....
I am going to have to get back down to my house I apparently had not sync'd the folder that the design was in to my...
???
You never got it? I sent it a long time ago :-\
I never heard from you so I assumed you had gotten it. I havn't gotten any e-mail's
I will build another one and send it again with a way to track it.. UPS delivers to Canada I assume?
USPS is ticking me off :( I have lost so much money on...
well shoot lol.... I thought someone might have replied about a proper opto setup.. ::)
I think its just a matter of cool and asteticly pleasing application when it comes to the PC.... I am wanting to know for another PC application.... but mine is for controling brightness of LED's :) which...
Yeah I am looking for a quantity order of them not huge but more than a few lol.. Thats what I actually did for the my proto-type.... I have a lead on the 4pin Molex plug at DigiKey thanks to "Cre" but still looking for a suitable supplier on the ATX 20 pin
I have been looking high and low and inbetween but cant seem to find a reasonable supplier for two connectors I need... I am needing ATX sockets (as found on motherboards) and 4 pin Vert. Molex Sockets that a Computer PSU would plug into.. Both PCB mount
ATX Socket (20 pin)
4 Pin Molex...
Thanks audioguru, I will give that a go in the morning.. Right now I am about to crash.. Just need to make one more post looking for a supplier for a couple parts I need... thanks for the input I will let you know what happens..
Yeah I spaced my timer connection to the 4017.... I will look into that LM331... The Thermistor I have from the thermal probe ranged from around 50K down to around 3K from ice cold around body temperature... If I had a way to lock it at around 90K and it would lower to around 30K I would be ok...
I tired to put a NTC Thermistor in series and in parallel with the Resistor on the RC to achieve this and it did not work out as I thought it would. As far as the Timer Cap discharge the Timer works fine just as I have it layed out and pulses the 4017 Cmos just as it should.. not sure what I am...
Not sure why you say its not complete as it is... but I will look into that page... the thing is I need this to change relitive to the temperature of the Computers CPU Heat Sink with no physical tuning by me.... which is why I wanted to use a Thermistor which I seen nothing on that page that...
Sorry for the late reply lol but it being Christmas and all ::)....
anyway.... Yes I was putting the Thermistor in the RC circuit
Its a NTC Thermistor commonly found on Computer Thermal Probes such as a CompuNurse and such.. Thin film....
Anyway... Here is the general schematic I just came up...
What is a Thermistor?
A Thermistor is a Thermal Resistor where as its resistance is determined by the themperature around it either negtively (i.e. the hotter it is the lower the resistance) or Positive (i.e. the hotter it is the higher the resistance)
I will post a drawing of the schem as...
Ok... I am working on a rather simple circuit to produce a heartbeat... nothing particularly special just a 4017 using a 555 timer for the clock. What I need to do is get the timer to be a certain speed at normal temp (set by a pot) and when a device a thermistor or the like is connected to gets...
