If it's infrared you won't see it until you don't see anything. With lasers don't sit around with a power supply trying to make a laser come on. Does anyone know where to buy these (stepper motor + lead screw assembly)? They're a beautiful design - I'd like to build a 9x9cm 2-axis plaster-of-paris (google for local name) engraver for metal casting. Parts of the housing are aluminum, others are (I think) mild steel, based on their magnetic behaviour. The magnet is connected directly to the threaded rod, although the rod does not carry the magnetic field.
I've never seen a motor of this design before. I've just taken apart one of the "Stepper Motors" and it consists of a cylindrical magnet surrounded by two highly-wound coils, one around (I'm presuming) each pole. (Motion control, anyone?) I can't remember if they can hold a load in position like a stepper. DC motors with high-resolution encoders (I've found more in printers than CD/DVD drives) with appropriate control firmware give more control than the small stepper motors or hobby servos, plus, assuming there isn't too much friction, you can record movements from the encoder/controller, and play them back. A few notes based on recent research and experience : 1. I've just learned the right way on the fourth CD Writer I've disassembled, but your instructable has clarified several points. If you are a dedicated Macbook user, obviously you need to opt for an Apple drive that is compatible with your computer and has the necessary software.Great instructable. You can find many options for both tasks among ASUS CD, DVD, and Blu-ray drives, or even LG, Dell, and Should you want to burn any yourself, you need a slightly different model. Some drives only read the discs you feed them. However, investing in a DVD drive seems more reasonable as this too plays CDs. Buying a drive that only plays CDs may seem like the cheapest option and is great if you only need to listen to music. This one is compatible with the CDs and DVDs, too, so you really need only one drive. In case you need a drive for Blu-ray discs, buy the more expensive Blu-ray option first. Think what kind of discs you need to read and burn. There is a huge difference whether a drive plays only CDs or also DVDs and Blu-rays. They connect to the computer via the USB port and are essentially like large memory sticks with lots more storage.

Thus, they are great portable options for taking your files with you when you do not want to drag the computer along. The external drives have become rather small and no longer require plugging in. Drives that connect to dedicated power sources are faster and relatively cheaper than the portable options.

Luckily, if you need to read or burn discs, you can install one or connect an external one.ĭesktop computers tend to do best with internal drives, provided that they have the necessary slots for installation. With cloud storage and streaming services available, the need for optical drives has decreased, so manufacturers are dropping them from computers to reduce the overall weight. CD, DVD, or Blu-ray drives are typical features on desktop computers, but modern laptops often come without any drive at all.
