Saskatoon TechWorks is now the proud licensee of VCarve Pro Makerspace Edition. What does this mean to you? As a TechWorks member, you can download the trial version of VCarve Pro and enter our Makerspace ID. (Ask us for it.) After entering our Makerspace ID, you can prepare your CNC job. That version will not save your toolpaths but you can do everything else to get your files ready for the CNC router. Save your project and bring your .crv file to the space, load it up in our “Master” copy, export the gcode, and you’re ready to make your masterpiece on our CNC router!
This two day workshop will teach you about voltage, current and resistance, and how to use a digital multimeter. You will build simple circuits with resistors to demonstrate that Ohm’s Law works. Then, on the second day, you will learn about capacitors, diodes, LEDs, transistors, and inductors. If you have your own DMM please bring it.

July 19th and 26th, 7pm: Arduino 101
This two day workshop will introduce you to the many forms of input and output on an Arduino compatible microcontroller. You will learn:
Many of our Arduino compatible devices contain a CH340 USB to Serial IC instead of the much more expensive FTDI chip. The CH340 is common in Chinese product, but not as common in products designed in the rest of the world. What this ends up meaning is, it is sometimes problematic getting them working on your computer. To make things easier, the following drivers have been tested by us:
Note that Windows 10 appears to include the driver, as does Linux. One extremely edge case, though, to be aware of: As of this writing, the Linux driver for the CH340 does not support parity. The STM32Duino we sell requires parity when installing the bootloader. To save yourself hours of hair-pulling, know that you will either need to use a different USB to Serial adaptor, or a different OS, or patch your kernel driver.
Somehow this message got lost in my inbox. So, when he says “Tues night” he’s actually referring to December 12th. Anyways, better late than never. Here is Rylan’s writeup about the new tool he made for us:
Hey everyone! On Tues night after the meeting I made a portable tail stock to match Albert’s motorized Chuck. It Took me all night but lucky I scrounged enough pieces of metal and the whole thing came together in one night — paint and all! I turned most of the parts on the lathe. My favourite part about the build was using a flexure and a clamp to adjust the height of the bushing near the handle at the back, that along with rotation of the large ring sitting on the flexure allowed me to align the back bushing very well despite the way that parts like to warp and shift as welds cool. Putting the ACME thread up on top instead of hidden underneath the carriage as is typical is a feature in this design as exposing the treads makes it them easy to clean with all the CNC cuttings.
This rotary attachment could also be easily be placed in the laser cutter and on the CNC router.
