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

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...

Hello Alan,
I need your help to fix a LED Km/Ph meter to my Bike.(Bike POV).do you have any kits like that.???
Replied on: 5:53am 10-13-2009

We don't sell a kit like that. For general help I would suggest that you ask it in the Hacked Gadgets forum.

hi alan I´m from colombia, I saw the hard drive clock and I think it´s really incredible. I want to do something like that. can you help to do that with the code specially and with more specifications with the parts?
thank you.
I wait for your answer.And i repeat again, congratulations for this excelent application.

Hi Jorge,

The code is available for free here. As far as parts go, you would need to purchase them yourself since we don't have a kit for that at the moment.

lookin circuits and hex file for Rotating LED Display
Replied on: 5:57am 10-13-2009

That code isn't available since the schematic was never provided.

sir i am from india.i am making the same spinning display but i am doing a little modification like interfacing the display with a computer with a rs232...can you please guide how do i transfer the text and certain pictures
Replied on: 5:59am 10-13-2009

Simplest way would be to store them as columns of data and have an array of these columns stored in memory (probably would need additional storage space). Then the display would simply display the data.

Hello i'm from belgium i want to make the rotating led display have you got the circuits pcb and componentlist of the project its important because its for my schoolexam.

Sorry, that project was built without a formal schematic. No other documentation other than what is on the site is available.

Deae Sir,
I want build one application using Induction heating i.e.500litre of cane juice to be heated at a temperature of 200 degree cel. So plz give a solution to use this application. Which type of well should I use and coil structure etc . I waiting for ur reply.

Thanking you.

Sorry, I have never designed a system like that before.

I have some old hard drives and was really interested in your Hard Drive clock however I don't have a pci programmer nor very good knowledge on circuit boards I looked but might have missed. Do you have any kits that are already pre-assembled that I could buy from you or someplace I can get one pre-assembled and possibly programmed where all I would have to do is hook up the wires to the Hard Drive and cut the holes for the drive?
Replied on: 8:36pm 09-16-2009

Sorry, no kits are available yet. It is still planned but I am not sure when it will be done.

You are awesome for designing such a great product to help your elderly kitty. God smiles on you!

Some schematics are provided, which project are you talking about?

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

That has been requested many times so it is possible in the future but at this time we do not have anything like that.

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)

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 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.
Replied on: 3:52am 05-26-2009

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