I purchased a few  led light sets on sale after the Christmas season they still were not cheap even after the 50% discount. I may want to make my own strings. Do you sell anything that makes the led twinkle? (random off & on) I may want to use a low voltage 12v power supply. AC

Hi Alan, great site!

We found you via your HDD clock. And we hope that you can advise us about how to make a standalone microcontroller-based (off the Web) version of our Synclecron, which is: 1) freely available on the Web using Flash, 2) soon to also be freely available on mobile browsers, and 3) also now runs on donated laptops (using J2SE) that we in turn contribute to nursing homes, .etc.

More specifically, please take a few moments to learn about our GreenTyme project, and then go to our orientation page to learn about & begin using our Synclecron. And then please give us some guidance about how we can, as inexpensively as possible, design and create very low cost standalone uc-based versions of our Synclecron? We are not looking to make a profit, but rather to maximize the Synclecron's use by sick people and those who are not yet sick.  

Warm regards, Yale S.Y.Landsberg, Executive Director (unpaid)

Followed here from you youtube video about the nr2003 dashboard. Great work. Wanna build me a unit I'll supply the dash(lol). I'm a mechanic and live for Nascar Racing 2003 only have basic electronic skills

Hi Alan
I was quite impressed by your hard disk clock when I first saw it a few years ago, and after all these years tried to build it. The problem is that i have opened up 4 drives so far ( 2 seagate 20 GB, one maxtor 80 GB and one samsung (do not know the size) and all of them seem to have one platter only. The motor spindle is not too high to accomodate more than one platter. Also out of the 4 drives, only the maxtor one spins on powerup (but in the wrong direction! which is clockwise) Is there any recommendations on the type of hard disk i should be looking at? When you say old, how old are we thinking of. I love your project and would like to build one soon! Your comments would be very my appreciated- Anjan

Hi Anjan,

It is hard to say exactly what drive will work for you. Most modern drives will not work since the drives have more smarts and will tend to spin down after a short time since there is no computer connected to the drive. I would look at drives in very old systems like 386s. Drives under 100MB should be good.

Hello Allen,
Thanks for your excellent website. I just saw the project "Stäubli TX 60 Industrial Robot under Wiimote Control" on Hacked Gadgets. My project is somewhat similar to this one, and I just start to work with the TX 60 robot. Actually, I don't know what to do now, did you built the program with VAL 3 Robot language or you use C language. because I need give some data to the robot from a sensor and I have built a application for the sensor use C with QNX operative system, I don't know how to use the robot under QNX and program it with C. Can your give me some suggestion.
Many thanks in advance!

That is a cool project but it was just featured on Hacked Gadgets. You will have to contact the creator for additional info. Drop us a line at http://hackedgadgets.com when you get your project done, I am interested in having a look.

hello allen, my name is MBADU im a student at cape peninsula university of technology(south africa). i visited your site and i find it very intresting, congratulation.
the reason why im contacting you is that i have been given a project at school to design a capacitor tester using a microcontroller the 8051 intel, and we using keil microvision for our simulation so i would like your help if you can by providing me some key explaination on how to start?
hope to read you soon.

I have not used that microcontroller before so I can't help you with sample code but this project should give you some ideas.

Hi Charlie,

Sorry for the delay in response. That project was just featured on Hacked Gadgets and was not actually constructed by me. There should be a link in the article that will lead to additional information.

Hi Alan

well, it seems that the only fault seems to be me!! The test procedure was very useful for me to comprehend how the system worked as I haven't studied your design yet.

I went through test procedure and it worked all OK
I then hooked it back in and it didn't work. hmmm, tested continuity of cables, all OK
I then went through hooking up each led and testing it with jumpers in place on the board. all leds worked.
I then hooked up the IR and tested it and it worked.

Obviously human error factor working against me.

I have them setup on spiral stairs and they work great. Now all i have to do is drill the holes and mount them permanently .

Thanks for making this project!

Good to hear it is functioning again. Sounds like a cool set of stairs!

Hey,

Got the stair light kit, pre assembled, tested it on bench, worked great.  Wired up into stairs, and went through setup mode worked great.  powered down, disconnected setup wire and powered up but nothing works now, only the green light.  checked all connections and they seem good.  Is it possible to harm the chip by handling the board (when i disconnected the setup wire).  i have tried setup mode again but that doesn't work either.  what should i do now?

cheers!

Hi Dayna,

Sorry to hear you are having some troubles. Please disconnect all wires and try the controller test procedure again and let me know what the results are. http://alan-parekh.com/kits/stair-light-kit/stair-light-kit-control-unit-test-procedure/

Most excellent light display. "I love to see the imager scanner" up close. I am just amazed that such detailed lettering could be visible with so few LED's, Continuosly amazed,

Which display are you referring to? The rotating LED display?

Hey Alan,
Love the lights in the stair case.They look even better up close. As I said  I will purchase them for my house. The clock is wild I have to come over again and have a closer look. This is my first visit to this site I will be back.

Awesome Stuff!
Robert

Thanks. We will have to get the stair lighting controller in your house this summer.

Hi Ala,

Just found your site.  I'm really impressed.  I have some home additions being done and I thought about LEDs on the stairway.  Can you buy the parts to install an LED system like your videos show?  Where?

Hi Ray,

You can purchase it here
