Obviously, the most iconic piece of fictional hardware from the Back to the Future films is Doc Brown’s DeLorean DMC-12 time machine. But we’d have to agree with [Jason Altice] of CodeMakesItGo that the second-most memorable gadget is the modified Futaba remote control used to control the DeLorean from a distance. Now, thanks to his detailed build guide, you can build your own version of the time machine’s controller — complete with working speed readout.
Now to be clear, [Jason] isn’t claiming that his build is particularly screen accurate. It turns out that the actual transmitter used for the prop in the film, the Futaba PCM FP-T8SGA-P, has become difficult to find and expensive. But he argues that to the casual observer, most vintage Futaba transmitters are a close enough match visually. The more important part is recreating the extra gear Doc Brown bolted onto his version.

We often hear it said that today’s kids don’t go out and play as much as they did in the past, but honestly, it’s hard to really blame them. Have you seen some of the games they have now? It’s going to take something a little more exciting than a game of stickball to get them off the couch when they’ve got 4K and VR game systems to play with.
Circuit to control ATX PSU
Which is exactly why [Bobek] is building his kids a time machine. Not a literal one, of course. The Flux Capacitor technology required has yet to be mastered. But it does allow the player to “travel” through time through videos which are played by punching in specific codes they have to unlock by solving puzzles in the real world. Then again, keeping keeping kids active and mentally engaged might as well be “going back in time” in some people’s eyes.
By the looks of things, [Bobek] still has a little work to do on the project, but it’s far enough along that we can get an idea. Inside the bottom of the heavy duty plastic case he’s installed an ATX power supply and a Raspberry Pi 3, and an top of that, there’s a metal plate that holds the power button, an RGB backlit keyboard, and a Vacuum Florescent Display.
After powering on the system, the kids punch in the codes they’ve earned on the keyboard. If accepted, it starts the corresponding presentation which goes over the sights and sounds of the time period they’ve unlocked. In the video after the break you can see [Bobek] test the device with a small display hanging off the end of an HDMI cable, but presumably the system will eventually get an integrated display. The kids could also plug it into the TV, but at that point you might be going full circle.
What do you get when you put an ultra-bright LED in the palm of a glove, and strobe it controlled by an accelerometer? A Time Control Glove! In creator [MadGyver]’s own words, it’s “just a stroboscope with frequency adjustment” but the effect is where all the fun is.
The Time Control Glove uses the stroboscopic effect, which many of us have seen used in timeless water drop fountains where the strobe rate makes drops appear to change speed, freeze in place, and even change direction. [MadGyver] made the entire assembly portable by putting it into a glove. An on-board accelerometer toggles the strobe in response to a shake, and the frequency is changed by twisting the glove left or right. The immediate visual feedback to the physical motions is great. The whole effect is really striking on the video, which is embedded below.
[Sam] is an avid Halloween builder and has been hard at work on a time-machine simulator for this year’s festivities (alternate link). He recently assembled the enclosure which is seen above. It’s got room for two riders who will be strapped in place, with plenty of interior items to keep them occupied. There will be three LCD monitors acting as front and side windows for the time machine.
In the video after the break (taken from his vblog on the page linked above) [Sam] walks us through all of the electronics that went into this. He’s got red lights controlled by a servo motor attached to a dimmer switch. There’s a vibrating seat to give the riders a jolt, and a control panel which shows the status of the time machine. The thing is, it’s not just the physical build that’s impressive. We know from his past projects that [Sam] is a showman and he doesn’t disappoint this year. He spent a lot of time filming and generating computer graphics and sound to really make the ride a multimedia odyssey.
With today’s release of Security Update 2008-006 Apple has finally addressed this summer’s DNS bug. In their previous update they fixed BIND, but that only affects people running servers. Now, they’ve updated mDNSResponder. Clients are no longer susceptible to DNS cache poisoning attacks thanks to the inclusion of source port randomization.
The Security Update addresses some other interesting bugs. Time Machine was saving sensitive logs without using the proper permissions, so any user could view them.
