Sieg X2P Mini Mill Drill

New Old Stock

• X2 mill with fixed column and large table
• Cast iron for vibration free running
• 500W variable speed motor
• Coarse down feed for drilling operations
• Fine down feed control for accurate tool height setting

The SIEG X2P is a 230-volt drilling/milling machine with a speed range of 100 to 2,500 rpm. It is powered by a 350 watt brush motor. The power is transmitted via a 2-stage gearbox. A shift lever is used to choose between the high and low speed ranges. The speed can be continuously regulated within the two speed ranges. Thanks to the reduction in the gearbox, the X2P has sufficient torque even in the low speed range. There is no quill installed in the X2P. The feed in the Z direction is carried out by moving the milling head using a quick adjustment with a star handle or using the fine feed that can be activated. Milling and drilling work can be carried out with repeatable accuracy using the adjustable depth stop on the Z-pillar. In relation to its size, the X2P has large travel distances in the X and Y axes. All guides can be adjusted without play using pressure strips. The speed controller, the operating light and the holder for the fine fuse are located on the front of the control unit. The emergency stop button and the fault light are located on the left side of the control unit.

Passive Desktop Monitor Controller

Heritage Audio’s Baby RAM is the ultimate passive-monitoring system, delivering the most transparent signal with the best stereo imaging of any other passive designs available!

The Baby RAM is a boutique, passive-circuit monitor controller inspired by classic European console designs. A Baby RAM is the ultimate controller for total transparency — a zero-compromise signal path, paired with a simplified control set ensures your monitors receive the cleanest, purest signal possible without unnecessary complications.

The Baby RAM proudly features a 4 gang, 24 step rotary switch for volume as opposed to cheaper stereo potentiometers, which means the precision of your stereo signal is perfect on every position as well as offering a subtenth of a dB precision on every single attenuation position! Baby RAM also has no insertion loss, meaning that there’s no extra coloration, signal loss or degradation at any settings.

Even though the Baby RAM packs a zero-compromise circuit design, it couldn’t be any easier to use with 2 pairs of stereo inputs and outputs — both balanced and ground free (unbalanced compatible) on gold plated TRS jacks. Mute, Dim, Mono, and Volume monitoring controls make the Baby RAM a breeze to work with. And with it’s passive design, it also means you have no concerns with bad power supplies, as no electrical current is needed!

The Baby RAM is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners.

Rocket Transits Rippling Sun

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

2022 May 31

The featured image shows a Falon 9 rocket transiting in front of the Sun in mid May. The heat from the rocket's exhaust makes the Sun's outline appear to ripple. Please see the explanation for more detailed information.

Rocket Transits Rippling Sun

Explanation: The launch of a rocket at sunrise can result in unusual but intriguing images that feature both the rocket and the Sun. Such was the case last month when a SpaceX Falcon 9 rocket blasted off from NASA’s Kennedy Space Center carrying 53 more Starlink satellites into low Earth orbit. In the featured launch picture, the rocket’s exhaust plume glows beyond its projection onto the distant Sun, the rocket itself appears oddly jagged, and the Sun’s lower edge shows peculiar drip-like ripples. The physical cause of all of these effects is pockets of relatively hot or rarefied air deflecting sunlight less strongly than pockets relatively cool or compressed air: refraction. Unaware of the Earthly show, active sunspot region 3014 — on the upper left — slowly crosses the Sun.

Apollo 16 Moon Panorama

Explanation: Fifty years ago, April 20, 1972, Apollo 16’s lunar module Orion touched down on the Moon’s near side in the south-central Descartes Highlands. While astronaut Ken Mattingly orbited overhead in Casper the friendly command and service module the Orion brought John Young and Charles Duke to the lunar surface. The pair would spend nearly three days on the Moon. Constructed from images (AS16-117-18814 to AS16-117-18820) taken near the end of their third and final surface excursion this panoramic view puts the lunar module in the distance toward the left. Their electric lunar roving vehicle in the foreground, Duke is operating the camera while Young aims the high gain communications antenna skyward, toward planet Earth.
