Steamboat Willie Still Tests Copyright

If you know anything about Mickey Mouse, you’ll be able to tell us that his first outing was in 1928’s Steamboat Willie — an animated short that sees our hero as the hapless pilot of a riverboat battling an assortment of animals and his captain. It entered the public domain last year, meaning that it and the 1928 incarnation of Mickey are now free of any copyright obligation to the media giant.

There’s an interesting development from Florida on that front though as it seems Disney may have been testing this through legal means, and now a law firm wants to see them in court over their proposed use of the film in an advert.

Of course here at Hackaday we don’t cover the dry subject of Florida legal news as a rule, but we are interested in the world of copyright as it applies to many other things that do come under our eye. As we understand it the law firm is requesting the judge assert their protection from trademark claims over the use of Disney’s 1928 Willie, given that there have been claims from the entertainment giant against others doing the same thing.

It’s hardly surprising that a large corporation might seek to use legal muscle and trademark law to de facto extend the term of Mickey’s protection beyond the defined copyright expiration date, so for once it’s refreshing to see them come up against someone unafraid of a courtroom.

We hope that common sense will prevail, and this undermining of a cherished right (not to mention prior case law) is not allowed to succeed. Meanwhile if you’d like a 1928 Mickey that Disney have shied away from coming after, look no further than the EFF.

A Ham-Adjacent Portable Radio Repeater

Although ham radio offers a wide array of bands to transmit on, not to mention plenty of modes to communicate with, not everyone wants or needs to use all of this capability. For those needing simple two-way communication services like FRS or GMRS are available (in North America) with much less stringent licensing requirements, and GMRS even allows repeaters to be used to extend their range beyond the typical mile or so. [Dave] aka [N8DAV] has built an off-grid simplex repeater that can travel around with him wherever he goes.

The repeater itself is based on a pre-built simplex repeater module, which means that it has to record an incoming signal and then play it back on the same frequency. Compared to a split frequency repeater which uses different frequencies for transmit and receive this can be a bit cumbersome but simplifies the design and the use. A Baofeng UV-5R is used to perform the actual radio duties paired to a 40 watt amplifier to extend the range as much as possible. It’s all packed into a Pelican-like case and set up with a large battery that could power it for a number of days, making it useful for camping, rescue, or other off-grid activities.

For those wondering why [Dave] is using his ham call sign instead of his GMRS one, all of the equipment in this build will work in either the UHF ham bands or the channels reserved for GMRS with minor adjustments, so it’s perfectly possible to use the setup for one’s preferred license. And, for those in other parts of the world without GMRS there’s a similar class of radio called UHF CB which might be able to support similar builds, but be sure to check your local jurisdiction’s laws before hooking something like this up. For an even longer-range radio repeater using similar equipment we’d recommend looking to the skies.
