Radar Gun Hacked!

Radar Gun Hacked!
Turn a 'toy' radar gun into a more pratical, useful radar gun with better features! While this is a completely new and different design, my inspiration for this project came from an article I read by Ken Delahoussaye. Check out the video and see it in action!

This is the Hot Wheels Radar Gun. They are available at toy store and the internet. Cost: Approx $25. This is a real radar gun that shoots doppler radar at 10.525GHz. It has a trigger you hold down and will adjust to 1:1 or 1:64 scale for shooting Hot Wheels cars in action. It also will display MPH or KPH. Time to hack it!

I have to agree, I don't see an obvious improvement. Could we have missed it? All I see is a different case...

I bought one of these off fleabay, but realised it was not very good so its sitting in the loft gathering dust. Do these changes actually make it work properly? I wanted to use it to measure someone bowling a cricket ball, but it won't even pick it up unless its bowled dead straight.

If I get this right, I think it has to work before you mod it. Doesn't mean it's useless, probably just handicapped. -Karnivore

Does this increase the speeds that it can detect?
Sep 12, 2007. 2:35 PMMr. Rig It says:
OMG! I can use this at work!!!! It looks so SciFi Tech to boot! Even your narration was great. I cannot say enough about this project. On another note:Uthman was right if you could hack the camera display the speed it would be fantastic. However, an officer doesn't have to have the speed on the film of the camera. All the officer has to do is read the radar speed and Bam ticket. The film is just proof that the offender was at the scene. For this particular tool though I would use it just as a deterrent to slow speeders down and let them know they are being filmed. Then the job is done. Great job.

AFIK the officers word is all that's needed to put an offender at the scene. No different than the court taking the officers word in regards to the radar display read out.
Sep 20, 2007. 2:55 PMMr. Rig It says:
That's true but being and Officer I have found that every little bit helps, so there is no shadow of doubt left.

does this hack make it work any better like becides batterie length? or is it just because like did the hotwheel thing work at greater speeds or what?

The instructable was was well done, again. Your independent product review was the most valuable for me. Having no immediate use for a radar gun, it may be some time before I bought a unit new. I'd probably repackage it as well, but it would be in a different manner, for a different look.

now, is the signal generated by this the right frequency and strong enough to trigger a radar detector? I have one of those "radar/laser detector testers" and I keep it in my car... whenever I see some cocky teenager in their 16th bday present (or I'm bored while driving) I whip it out and point it at them... mostly, it's followed by screeching brakes and a scared look on their face as they look for the cop car...

where did you get that useful "testing" device? I searched on google, etc but only came up with testing results, etc.
Sep 14, 2007. 5:43 AMjongscx says:
okay, I couldn't find it either, which makes me really curious now... however, one possibility is that it's a microwave door opener... kinda like a garage door opener... aparently, big commercial doors work on the same frequency as police radars.
Sep 14, 2007. 5:16 AMjongscx says:
...the flea-market... it was unboxed and all the stickers were worn off... I thought it was an LED flashlight (the the seller had NO idea what it was) so I was lucky and got it for $.50... turned out to be a good find though... I've seen them on the internet, I'll check to see if I could find it again.

how is this "more practical" or hacked? all you did was put it in a different case and used AA batteries instead of AAA. And what is the point of mounting it on a video camera? sure you'll have a video of what you were clocking but you don't have an onscreen display of the speed. I think the gun looked better stock.
Sep 13, 2007. 8:46 AMstevoIution says:
I concur.
Sep 12, 2007. 6:45 PMjoemonkey says:

impersonation of a police officer is illegal (think lots of jail time).

Sep 12, 2007. 12:43 PMjridley says:
Yeah, looks to me like it was made less practical; it's now bigger and uglier. I was kind of hoping someone had come up with a replacement firmware that would go over 100 MPH or something (it uses a standard Atmel microcontroller and is reprogrammable). The only new feature here is always-on; you could replicate that hack with a rubber band. I guess tripod mount too, so use some duct tape as well.

ROFL @ the pic of u throwing the baseball if you could somehow hack the video camera to display the speed, that would be sick

i think it said 62 in the vid

There's no such thing as over the top. Nicely done.
Sep 12, 2007. 8:53 AMesrun says:
Well done on the effort you went to on documenting it but I think you went a little over the top for the results. I would have just attached a tripod system using some zip ties or similar..
Sep 12, 2007. 8:25 AMballoondoggle says:
I have to agree with beerboyone: you've just made it ugly. BTW, cops do have radar\laser guns with cameras, but there are enforcement issues with the unattended stations similar to the debate over redlight cameras.
