NEW PRODUCT – CD DVD Spindle Motor


What’s this? A record player for ants?? Not at all! This is a CD/DVD Spindle Motor, that thing that’s inside a CD or DVD player, that turns the disc around really fast. These motors have some great benefits that make them easier to use than ‘130’ style DC hobby motors.

  • For one, they’re mostly flat on the end, so you can tape or glue it to a flat surface easily.
  • They are well balanced, don’t vibrate a lot which makes them nice and quiet compared to most other motors (they’re not totally silent)
  • They spin fast, about 3500 RPM at full power – can PWM the motor driver to reduce speed
  • 20 mA free running current, 400mA stalled.
  • The motor is rated at 5.9V max. You can use 3V to 6V DC, the speed and torque may vary
  • They’ve already got a plastic hub on em, so it’s super easy to attach whatever you like

It is a motor, so you’ll need a motor driver to control it. We recommend CRICKIT for easy motor control, but you can also use an Adafruit Motor Shield for ArduinoMotor HAT for PiMotor FeatherWingL293DTB6612 or DRV8833.

    Turning Cheap WiFi Modules Into Cheap WiFi Swiss Army Knives

    When the ESP8266 was released, it was sold as a simple device that would connect to a WiFi network over a UART. It was effectively a WiFi modem for any microcontroller, available for just a few bucks. That in itself is awesome, but then the hackers got their hands on it. It turns out, the ESP8266 is actually a very capable microcontroller as well, and the newest modules have tons of Flash and pins for all your embedded projects.

    For [Amine]’s entry to the Hackaday Prize, he’s using the ESP8266 as the ultimate WiFi Swiss Army knife. The Kortex Xttend Lite is a tiny little WiFi repeater that’s capable of doing just about anything with a WiFi network, and with a bit of added hardware, can connect to Ethernet as well.

    The hardware on this board sports an ESP8266-07S module, with two free GPIO pins for multiple functions. There’s a USB to UART in there, and a voltage regulator that’s capable of outputting 600mA for the slightly power hungry radio. There’s also an integrated battery management and charge controller, allowing this board to charge an off-the-shelf lithium cell and run for hours without any wires at all.

    So, what can this board do? Just about everything you would want for a tiny little WiFi Swiss Army knife. There’s traffic shaping, port mapping, packet sniffing, and even support for mesh networking. There’s also an SMA connector on there, so grab your cantennas — this is a great way to extend a WiFi network, too.

    This is a well-designed and well-executed project, and what makes this even more amazing is that this was done as one of [Amine]’s high school projects. Yes, it took about a year to finish this project, but it’s still amazing work for [Amine]’s first ‘high-complexity’ design. That makes it an excellent learning experience, and an awesome entry to this year’s Hackaday Prize.

    Oil-Immersed Raspberry Pi Keeps its Cool Under Heavy Loads #piday #raspberrypi @Raspberry_Pi


    Img 6902 e1533852554228

    The blog 314REACTOR experiments with liquid cooling a Rasperry Pi. Via Hackaday:

    As a general rule, liquids and electronics don’t mix. One liquid bucks that trend, though, and can contribute greatly to the longevity of certain circuits: oil. Dielectric oil cools and insulates everything from the big mains transformers on the pole to switchgear in the substation. But what about oil for smaller circuits?

    [Lord_of_Bone] was curious to see if an oil-cooled Raspberry Pi is possible, and the short answer is: for the most part, yes. The experimental setup seen in the video below is somewhat crude — just a Pi running Quake 3 for an hour to really run up the CPU temperature, which is monitored remotely. With or without heatsinks mounted, in free air the Pi ranges from about 50°C at idle to almost 70°C under load, which is pretty darn hot. Dunking the Pi in a bath of plain vegetable oil, which he admits was a poor choice, changes those numbers dramatically: 37°C at idle and an only warmish 48°C after an hour of gaming. He also tested the Pi post-cleaning, which is where he hit a minor hiccup. The clean machine started fine but suffered from a series of reboots shortly thereafter. Twelve hours later the Pi was fine, though, so he figures a few stray drops of water that hadn’t yet evaporated were to blame.

    Is oil immersion a practical way to cool a Pi? Probably not. It doesn’t mean people haven’t tried it before, of course, but we applaud the effort and the careful experimentation.
