View topic - Lab robot conversion to laser cutter. I tried the chiller on a hot day in the shop and found a problem.
The chiller uses an 800 watt heater to regulate the temperature. When under the control of the laser power supply there is too much gain in it's PID loop and the temperature shoots way up before dropping and stabilizing after at least a half hour. Since there is no way to adjust the PID loop in the power supply I had to do something on the chiller side. Somehow I needed to reduce the power going into the water. Thought about a resistor but that would be a waste and just get things hot. They are a module in the same form factor as a standard SSR. Then the start relay went out on the compressor. I decided to eliminate the cable tray that the Y axis cable lies in when it moves back and forth. Next was getting the gas assist connected. I wanted something a little better than a generic power strip for the system. I still need to do something for the Z home switch and need to start finishing up the wiring.

You, easily. 1) If you have the openscad file which created the object you could hack that to add at the end the shapes and make a boolean operation (substraction) between the initial result and two new rectangles created to enclose the object (mould sides). 2) If only a stl is available, i dunno what openscad can do with that alone. Try freecad 0.12. Import the stl, create its shell, convert it to solid, boolean substractions, test the outputs.

I have a few weeks off before my next intership. I have a tonne of video to upload because I have been using the scooter a lot!! I have a couple of miles on it. I broke the belt a couple of time and I am right now waiting for a new belt, got 2 this time. I am also working on a belt tensionner, I realise it is important (but to lazy to build one) since the belt slips a lot due to high torque when starting the scooter. I bought these new Turnigy Nano-Tech battery from hobby king. Here are some of the highlight Fast charge capable, up to 15C on some batteries. Since V = RI, and we have a 3mΩ resistance per cell in my standard battery and consume 80Amp at peak.
When you have 14,8V, that is 4 time 3,7V cell. V = 0.012A * 80 V = 0,960V of drop out. (960mV) CrustCrawler AX-12-18 Hexapod Robot BETA. X-walker quadruped robot, tilt control. Passive Magnetic Bearing Development. Passive Magnetic Bearing DevelopmentPresented by Mark Siebert Univ. of Toledo and NASA Glenn Mechanical Components Branch Flywheel energy storage systems are being considered as efficient energy storage devices for use on unmanned, low earth orbit satellites.
These systems are expected to provide five to ten times improvement in specific energy storage capacity with longer life than current battery systems. Low-loss magnetic bearings will be needed to support the flywheel rotor. For smaller satellites, we are investigating a simple system that uses only passive magnets for radial bearing support and jewel bearings for axial support. Embedded Junkie. Openpnp - Open Source SMD Pick and Place Hardware and Software. Mailänder Messestand von der Ippolito Fleitz Group. Freitag, 25.
Mai 2012 RoM Die Mailänder Möbelmesse 2012 nutzte der Möbelhersteller Brunner für die Vorstellung zweier neuer Produkte: des Hockers »hoc« und des modularen Sitzsystems »plot«. Erneut wurde von der Ippolito Fleitz Group ein Raum geschaffen, der an eine Installation erinnert, und die neuen Möbel von Brunner in einem intensiven Raumerlebnis präsentiert. Ganz in Schwarz und Weiß gehalten nimmt sich die Umgebung aus der Ferne zugunsten der farbigen Sitzobjekte zurück, die so zum Ausprobieren einladen.
Aus der Nähe betrachtet wird der Hintergrund zur poetischen Entdeckungsreise durch eine Textwelt, die den Besucher zum langen Verweilen animiert. Inspiration für die Gestaltung gibt das System »plot«. Genau diese Momente, Ereignisse, Gefühle spiegeln die umgebenden Wände wider.
