Hacking the Hot Wheels Radar Gun

Hacking the Hot Wheels Radar Gun


Ed Paradis has put some thought into a couple of hacks for the Hot Wheels toy radar gun:

The Hot Wheels Radar Gun is a real radar gun currently (Feb 2007) available from Walmart and other retailers for about $30 (USD). It is a real radar gun, operating at 10.525 GHz capable of clocking cars, people, pets, and toys.

But before you can play with it, you’ve got to get the thing open! Here are some pictures of me taking the thing apart.

You can use the radar to detect the speed of moving objects, but Ed also posted some semi-successful (and some not-so, but worth reading) experiments with using the device in a custom circuit to detect the distance of objects for robotic projects. It’s also worth noting that the LCD can be repurposed as a display output for your other electronic gizmos. For 30 bucks, it’s a pretty good collection of useful robot parts.

    I have the strangest problem with Gmail and Mobile Outlook. I have an ATT 8525 (aka HTC Hermes) with Windows Mobile 5 Pocket PC edition.

    Email disappears from my Mobile Outlook inbox. It will pop one or more messages from the server and issue a Windows Mobile notification telling me I have email messages available but the email count on the today screen will be 0 and when I open Mobile Outlook from the notification my inbox is empty. The missing email is available through the Gmail web interface.

    This does not happen with the exchange account I have setup on the same device.I haven’t been able to find anyone else with this problem and support has been less than helpful. I can only hard reset the device so many times.

    I have the same problem and have found no answer.
    I read someone stating that using ‘recent:usename@gmail.com’ at the the POP settings solved the problem, but honestly it starts downloading 651 emails form the last month.

    I’m currently using the WM6 in a T Mobile Dash
    Can anyone help?

    I had the same problem with my emails dissapearimg from my MDA Vario 3 – found the problem went away after I set the client to download headers only.

    The problem is that the messages downloaded to your PDA are automatically deleted from the server or archived. This will solve this problem: http://pomo.desofto.com/

    Yes, all you do is make sure you have Outlook 2003 or later and then download and install the ‘Google Calendar Sync’ application. Once you sync the phone to the computer, Outlook will sync with Google Calendar and viola.
