Motorcycle LED Sign: Drivemocion

This is a video response to Sven's video about a motorcycle LED sign. I'm not sure that Sven actually got this working the way he made it look. I try and dig in and figure out how to make this a reality.

Any further with this?

[AtlasRider]

No, haven't fiddled around with it any more. Need to make a trip to the electronics store...

[svengalie]

You done it yet chief?

[AtlasRider]

Nah I broke it :(

Had it working at one point though. I know what's wrong, but I don't know how to fix it :(

Best to extend the Transmitter diode into the receiver housing. Remember that diodes are polarity sensitive so connect up the way as it was in the controller. There is usually a 'flat' on one side of the Diode to help differentiate. Any old 2 core cable will do - there is practical no current needed. You will need to silicon round all holes and joins in both units if its not waterproof.

I forgot about the sunlight sensitivity. That's a good idea to put it inside the remote. Going to try it out. Thanks!

Ask Kip Kay, I'm sure he can help!

WHere did u buy this?

Oh. Just make sure your led drive voltage is above 0.7 volts or it won't be able to directly drive the transistor.

[pcarlson1979]

The transmitter will use an IR LED. On the display it uses an IR Receiving transistor. You just need to connect the Anode from the Transmitter to the emitter of the receiving translator and the cathode of the led to the collector of the tranny. Voila. Hard wire connection.

Where can I get one??

[Biggerbadwolf]

You might try using an OPTO ISOLATOR, as an interface between the remote & the display unit.

[skatepeak]

that one is useless.

You want one that can "roll" the text.

That way you can send whatever message you want. Regardless of the lenght.

With that one, can you only type messages in max:: 2 words with max.: 3 letters in the last word??

There are a few things you must do to get this to work properly.

1) Relocating the Infrared up frnt will not work.. Sunwash. U must have direct connect.

2) Weather sealant is a must for display and remote.

3) I thought I saw 4AA batteries. That is 6vdc. U will need two 7805 voltage regs from rad shack to conver 12v down to 6vdc. One prob for display unit and one for control box (unless u run multiline cable up there 2 carry pwr).

its possible! ) Great video! :)

Always a good idea to tell cagers to "back off". Like that's really going to help. Not only novice advice about electronics, but more novice advice about motorcycling. If you have a tailgator that won't back off, given the disparity of the size/weight in vehicles, I let the cager pass every time. No way I'm going to come out ahead getting into a conflict with a car. Sure it upsets me to be tailgated, but nothing worth dying over!

Extending the IR Tranceiver will probably add WAY too much resistance/impedence through attenuation. You are going about this all wrong!

Create your own control box with your own buttons/switches using a project box and some switches from any old electronics store. Rin the wires out of that and solder them onto the PCB in the control box where the built-in buttons are. Wrap up the wires into a cable and mount.
