I'm making LED turn signals for my Jeep. Those little LED boards are a big help.
I'm sure I'll have voltage ?'s later.
Nice site.

Glad to hear they worked good for you!

Hi ,
I want to know how a character is mapped with some values to make led on and off.
How to find this some value for every character. kindly help its regarding my college project

You can make your own or use something like this.

just a few questions i have for you

on the single button entry thing:
- what voltage is output?
- if it is in the normaly open hole will it put a constant out put until the right code is entered and then cut off the output for the set amount of time or is it the other way round?

on the hard drive clock
- when you get round to doing a kit for it (hopefully very soon), would you be able to add a RTC to it so i can use it as an actual clock?

Hi Thomas,

There is no voltage that comes out by default, there is a relay that activates. Have a look at this page for a some more details of how a relay operates.

The Hard Drive Clock will be able to keep accurate time when it is made into a kit.

Alan, I just watched your "What really ticks me off" rant from www.hackedgadets.com about "Fixing a Plasma TV" and "Engineering Headhunters" and really enjoyed it in your quixotic Ozzie accent. Very entertaining - and I commiserate. As I get just as ticked off about similar things - but it was strangely cathartic to see you rant on like that. Now I know how I look (except in a Canadian accent eh?) Thank-you for helping me laugh at myself and I know that next time I feel my blood pressure rising because of something that "ticks me off" I will remember your video and it will ease my temper in some way. That may have been your intent - or maybe not. Thanks anyways. crj

Hi Christopher,

Actually this post you are talking about http://hackedgadgets.com/2010/01/02/how-to-repair-a-plasma-tv/

Was done by Dave Jones, see his blog here

I also got a kick out of the fix!

Hi Alan

does the HDD have to be a certain speed for the HDD clock
if so what speed?
also if i had one at a different speed what values would i have to change in the code?

Thanks
Replied on: 3:40am 01-05-2010

I believe the drive is a 5400 RPM drive. Unfortunately there is no simple way of changing the value with out recompiling the code. I will probably be making this project into a kit soon. The kit would automatically detect RPM.

hi alan,
i'm a computer science student .... my graduation project is about human computer interaction in which i use the wii mote device to track IR LEDS...but i noticed that the wii mote can't recognize which is the first LED and which is the second as these leds are fixed to the corners of a movable display which is used as projection surface ... when the display is out of the projection area or ata least 1 of the Leds on the corners is lost i need to estimate it to project the image correctly ...the problem is wii mote isn't able to know that this led is the first and the is the second so when the second is lost the third led becomes the second led ..is there any method in which the wii mote can recognize the IR LEDS and keep them in order ?
thx..best regards

does the hdd for the hdd clock have to be a certaib speed?
if so what speed?
Replied on: 3:43am 01-05-2010

Yes, the code was made to work with that drive in particular. I believe it is 5400 RPM

Hi Alan
justanother quick question
can i use a PIC16F628A instead of a PIC16F628?
Replied on: 3:48am 01-05-2010

That is fine.

Hi Alan
i want to buld a HDD clock but would it be possible for you to make a more detailed guide with pictures so that it is more clear and easier for me to understand?
Replied on: 3:48am 01-05-2010

There should be a kit available later this year.

Alan, how about a copy of your code for the spooky Eyes?

Hi Toby,

That project was featured on Hacked Gadgets. The code for the eyes can be found here.

Hi Alan, attempting to build the HDD clock - have a Maxtor drive 250GB which has failed - MaxLine2, 4 platters, had clockwise rotation which has been solved by swapping 2 of the motor leads, does speed matter, not sure of its speed?
Thanks for a great site ;-)
Replied on: 5:53pm 10-30-2009

Yes the speed matters. Look in the code, there are values to adjust some of the time delays that have to do with speed.

Hi Alen I recently read about your Led_UV scanner and would be interested in having one. I would like to contact you in order to commision the building of a new one or buying an existing one.
Thanks in anticipation
Replied on: 5:55pm 10-30-2009

That scanner was only featured on Hacked Gadgets, we sell UL LEDs but we don't have built units available. Unfortunately it would be cheaper to buy a commercial unit that have a custom one of unit built...
