Open to the public. Stop In! Wednesday Open Space Nights are our informal nights where we work on a variety of projects: Personal, Infrastructure, or group designs. Come visit and join in the fun, We look forwards to meeting oyu.
How to find us: Enter rear main door on second level, and take one flight up. The Rear Entrance is located up at the top of the ramp.
Sometimes when we hold workshops or lectures at CT Hackerspace, it would be easier to have a small form factor enlarger to help with demonstrations. Most current systems are big and bulky, and units that integrate into computer systems can be cost prohibitive.
These Molex connectors are used around CTH on stepper motors in several locations. They were used on the xylotex drives used on one of the projects. They work ok and are inexpensive, and allow a lot of flexibility swapping controls and motors between various computers running linuxcnc and now the driver for one of the 3D printer projects. It is really convienient to be able to swap hardware if only to maker sure a motor is running right.
Recently I have been messing around with a lot of motor control circuitry that requires a pulsed input signal. While I coud have whipped up a quick arduino sketch to generate a pulsed output signal, it seemed like overkill. Also, this is something that I wanted to have available as needed without having to flash an arduino etc.
I have recently found myself interested in being able to see the output of various devices having signals that require an oscilloscope to view. I had seen a sound card oscilloscope working on one of our public computers at the space but wanted something to use on my laptop. I also wanted to be sure that I didn't blowout the sound card or mother board on my laptop.
Want to make something? Come on by. Want to talk about making something? Come on by Want to figure out what a Hackerspace is? Come on by. We are open to the public on Wednesday the 23rd.
Past weeks have had everything from 3d Printer building to furniture making and welding workshops. If you have had an idea for something that you have been wanting to make but don't have a place to do it, come down to CT Hackerspace to see what it is like to have space to build and be creative.

Retired the Dynapar Encoder for the Sherline Lathe. It was losing pulses according to O-scope built into EMC2 (now Linuxcnc.) More importantly it didn't work all that well in threading. For another attempt I made a encoder with a couple of QRB1114 Optical Detectors and electrical tape. (unfortunately the QRB1114 is discontinued.) Also made a spindle speed display on the arduino that reads rpm from the sensor on the spindle.
Welcome and stop on by our regular (open to the public) Wednesday Open Space Night. If you have been wondering what this Hackerspace stuff is all about, feel free to stop in this Wednesday. Although there are not any specific activities planned, there is always something happening here on Wednesday night. Last week we went from checking out some welding equipment to see if it worked to an impromptu welding workshop. 3d printers are being assembled, CNC machines are coming together, members are working on their own furniture projects.
