The IR Jammer is a device that overwhelms an IR detector so that normal commands can not be received.

Hi Alan - I purchased the stair light system a few months back while completing my basement. I have finished it and installed the lights and they are fabulous. People love the system and many have inquired about it. My friends on FB are impressed and I have pointed them in your direction - please expect a few hits and some orders of the same.

Glad you liked it! Thanks for the promotion to your friends.

Hi Alan,
I was looking to see how did you make that hard drive motorcycle. I thought it was so cool and I would like to make one for my uncle.
Replied on: 12:35am 09-16-2011

Yes it looked great. It was just featured on Hacked Gadgets though and was not made by me.

Hi Alan,
I could help and recommend a PIC Programmer, to record the (stair_ver1_0.exe) in the pic16f628

Hi Kurt,

I would recommend a PICKit 2 or 3.

Hi Alan, I'm from mexico and new in the electronics, I have problem to mount the LEDs on the plates R1, R2 Stair Lights will be possible to put a picture in the manual did suchas IR Transmitter Assembly, I am very clear about the configuration through I hope you can help me and my email is

Hi Flor,

You can see on this page how the PCB connections are made.

This project shows you the step by step process of using one to power an LED.

Dear Alan,

Hi, Can you please send me the diagram for the analogue car temp and fuel gauge to digital conversion. Please send it to my email address. I need it badly thanks !

Replied on: 8:08am 06-30-2011

This sounds like a project on Hacked Gadgets. Most of those project are just featured there. Please check for a link within the article for more info.

Dear Alan Hi!, Thanks for this nice POV project. I want to assemble the rotating led display. Pl. send me the circuit diagram and the source code.
Thanks and with regards.

Sorry, that project was done long ago and unfortunately I don't have the code for it.

can u suggest a method to build an RF reader which can hav a range upto 100 meters or above?
Replied on: 8:12am 06-30-2011

There are long range ones but I am not sure about 100 meters.

I liked this progect it is something I would like to try myself.
Replied on: 8:13am 06-30-2011

Great! Let me know how it works out.

You used sliprings to get the power to the rotor (You will damage the bearings passing current through them). I did the same thing with the following differences: A 4: circular circuit board carries the LEDs, a 6808 microcontroller, and a 27turn coil around its outside. Another 9turn coil or slightly larger diameter is mounted stationary close to the rotating coil. It is driven from 4 FETs and another microcontroller. The stationary controller accepts input from a serial link (or has a self-running program) and drives the outer coil at 27KHz. The inner (rotating) coil picks up power by induction, and powers the rotating controller and LEDs. The information is sent by +/-90 phase modulation of the 27KHz. No sliprings needed. If you are interested in the design data for this, send me an email.

Interesting idea. Sounds like something that would be great to feature on Hacked Gadgets if you would like.

Comment about your meter clock: Your meters are way underdamped. You can fix this. The meter will be (I assume) a standard D'arsonval movement with a resistor in series to set the voltage scale. Disconnect meter from clock. Find the direct connection to the movement and connect a resistor substitution box directly across the meter. shake the meter (rotationally, about its axis, to cause the meter to deflect). With the meter movement shorted, you will have a grossly overdamped response (almost nothing). (That is how meters are shipped). Start with high resistance, and work down. Decrease resistance until the meter is critically damped (resistance that just stops the overshoot). You want to modify the resistor network to present that resistance to the meter. You will need to reduce the series resistance to restore the voltage calibration (roughly, anyway). Then you won't have all that bouncing going from 59 to 0 or 11 to 0

Great idea, I never would have thought to do that. I will need to give it a try on the next meter project!

hi alan, how to change the 5600 rpm hex code to a faster hard disk that run 12000 rpm? hex file.thnks
Replied on: 8:22am 06-30-2011

There are variables in the code that set the hand width and other widths, they will need to be adjusted by trial and error. You will need to compile the new HEX after each modification.

Hi Alan, i had build your Hard dirve clock but when power up a short time the led will going off, why? pls give some advise, the led just very bright at start but going dim in a few second, and go off. is any problem with the code i burn, i can't find 2n4401, so i use S8050 instead. and the index sensor hole i drill only 3mm is that ok?
Replied on: 8:25am 06-30-2011

There are quite a few new drives that have some type of failure recovery mode. It looks like yours has this mode. I am not sure if there is a way to disable it.

Those replacements should be fine.

I would like to know if you can make me a device just like IR Remote Control Jammer that would work also on 58khz or maybe you can modify one of this device and add the 58khz frequency to it.Please give me an answer and estimated price including 58khz frequency. Also if you are kind to answer me if this device block the acousto magnetic frequency. Thank you very much!
Replied on: 8:27am 06-30-2011

Yes it would be possible. The code is free to download and modify.

At the moment there is no option to have custom firmware created by us since we are very busy. Sorry.
