Zeroplus LAP-C Logic Analyser Logic Cube Windows 8/8.1/10 driver

If you are struggling with the LAP-C logic analyser driver under Windows 8, 8.1 or 10 - you found a right place to be :)

I haven't used it in past few months so I was very surprised when Windows said that is not happy with the driver (after upgrading to 8.1). After spending number of hours finding a solution I came up with this:

1. Download http://www.zeroplus.com.tw/software_download/lac_s31200_all(win8).zip (this is their official file however, I couldn't find it in any place on the zeroplus website)
2. Extract the zip file.
3. Navigate to the "Driver Setup" folder and extract the "Data1.cab" file (or double click on it to see its contents).
4. Copy the following files to: "C:\Program Files (x86)\PC-Based Instrument\ZEROPLUS\DRIVER\"
 - Bulkusb.inf8 and rename it as bulkusb.inf
 - Bulkusb.sys7 and rename it as bulkusb.sys
 - Bulkusb64.cat3 and rename it as bulkusb64.cat
5. Go to the Device Manager, right click on the LAP-C Analyser device, select "Update Driver Software".
6. Click on "Browse my computer for driver software" and select the folder from point 4 above.
7. Enjoy!

Hope it helps!  Thanks for big thumbs up!

Flat mounting clip for Velleman K8200 3D printer

Here is just a quick follow up on my previous frame clip (http://ljwinkler.blogspot.ie/2014/01/frame-clip-and-locking-pin-for-velleman.html). The middle section fits snugly into the aluminium profile only if there is no flat cable or other wires running along, that’s why I have created another version of the clip, this time with flat middle piece:

And here is the result:

The rest of the clip remains the same. It contains exact same rectangular holes on both sides and the pin designed previously will work as well. However, a countersunk M3 or M4 bolt needs to be used:

Frame clip and locking pin for Velleman K8200 3D printer

You probably discovered that mounting any accessories on the printer’s frame is a bit inconvenient. It is a good idea with these square nuts slid in the frame but unfortunately if you want to add something after the printer is fully assembled – it can be very ungrateful.

Some of the areas are easy to be modified, like the vertical aluminium profiles – it requires just removing the top caps. However, some areas are very hard to access (like the Z carriage arm) – you would need to tear the printer apart to get into the groove in the aluminium profile.

I had to figure out how to hang something on the frame without disassembling the printer or drilling holes in the frame. The list below shows what I would like to change/add to the printer:

• mounting the controller board on a separate base (probably with some cable tights)
• mounting the power supply on the side/back of the frame
• mounting the fan properly (it is very wiggly by default)
• adding a LED lighting (probably PWM controlled)
• adding a RaspberryPi to control the printer remotely
• adding a webcam to see the printing progress
• adding an extension lead where I could insert all the plugs (printer, RPi, LEDs)
• mounting the extension lead to the frame (the idea is to have the printer portable, with only one cable sticking out with the rest mounted securely)
• adding a filament cleaner
• adding a dishwasher (or maybe not, it would be too much for the frame :))

Here is a cross-section of the aluminium profile:

My first thought was to design a locking pin that would slide through the slot and then lock if rotated 90°.

After some measurements I came up with this bracket and pin:

I have created rectangular holes on the sides of the clip to allow the pin slide through.

Below are the printed objects.

A flat M3 bolt + washer or flat M4 bolt (like the one below) can be used.
