I would like to see the actual light that you would see once installed when you come down the stairs.  Can you send me a picture of the staircase looking at the lights in front of you?
Thanks,
Donna

We recommend side lighting so that the LEDs are not shining directly in your face when it is operating.
Have a look at the videos on this page for an idea of how it will look.

Hello Sir,
As per your Circuit Diagram for Genarating Ringtones on PIC16F87x,,What is the Amount of  Input Voltage given to Vcc,and Also where shal;l i place the Microcontroller... Is it on Bread Board or Microprocessor Kit...?
Please Give me Sufficient Details and Help Me,
Is Output can Be Availed From the Circuit Diagram which you have given on Site..?

Hi Sandy,

Actually the manual is not sent with the kit, it is available online here:

Been a fan of Tesla and electronics for years. Good to see others that like to look deeper into things.

Actually the Tesla coils that have been featured on Hacked Gadgets have been created by others and simply featured there. Click on the links within the articles to go to the creators site.

Nice Project

I designed something similar but never got around to putting it together. Would you be interested in building a similar system that would also monitor ph, control heat, control main lighting ( MH/ CF), and also control a CO2 system. I have most of the desgin worked out I just couldn't find enough detail on the PH probes.

I don't have the time right now to take on a project like  that but it does sound very interesting! Let me know if you make some headway on it. That would be great for http://hackedgadgets.com

Stop HGadget Spam

Your site keeps spamming... fix your mail server!!!

Replied on: 12:19am 01-26-2008

Could you please forward me one of those emails. I am sure someone is simply using the domain name in the return email address since it's just spam... By looking at the originating mail server I can ensure that it didn't come from our servers.

Hi Alan,
Quick correction, Transistors are 4403, not 4401, sry bout that.

Hey Alan
My new Neighbour saw the Stair Lights i installed at my house. It seems they have made quite an impression. He is renovating his basement and wants me to install a set for him. However, he has exactly 10 steps from top to bottom, but he also has a small landing at the base of the stairs which he would like to illuminate with the last step. As per your instructions, you can only have 2 leds, per output. My question. Can you use a higher rated transister on the last output, and have more then 2 leds connected. Or can you hook multiple 4401's to the same IC output and have them power more Leds, and operate in sync.
(in Short, i want to add more lights to the last output)

IN addition, I think i will order the premade board from your store, just to save me some time. As you are from Winnipeg, i was wondering if it would be possible to pick up the board, rather then have it shipped. (Im in the Transcona Area)

Appreciate all your help
Hope to see some more projects soon!!!

Hi Colin,

As designed the outputs only allow enough current to power up to 2 LEDs. This limitation is not due to the transistor limit but the biasing of the transistor to prevent output short circuit damage. A small circuit change would allow for additional lights to be driven, but it would also remove the short circuit protection. We are only mail order but we may be able to work something out. A new project is in the works.

Regards,

Alan

Hi Alan

I was given a solar panel charger as a gift at Xmas (with the intention of being able to charge my Nokia phone and my Video iPod). Phone no problem, but it didn't come with an adaptor for iPod/USB. Now, seeing your Hacked Gadget making an adapter from barrel adapter to USB, I'm planning to do the same. The only thing that concerns me is that the solar charger's output is specced as "4.5-7V" output. Seeing as the standard USB voltage is 5V (I think), would I cook my iPod connecting this directly? And if so, how can I sort this out?

PS: Brilliant and entertaining site!

You should be fine. Just double check the input rating of the devices and make sure they can accept that voltage range (should be in the manual). One thing you could do is setup a simple zener diode circuit to prevent over voltage if you thought it may be a problem.
