A Quick and Dirty Guide to PyQt5
A Quick and Dirty Guide to PyQt5
So far I have seen a lot of guides that introduce the PyQt5 as the saviour of humanity, the holy hand grenade of all the GUIs out there, but I have not yet seen a guide where… well, you start with a basic stuff. Where you abuse the notation at first, make errors, just to get things going.
So here you go – a totally wrong, dirty guide to how not to write in PyQt5! With examples! And NO QML.
Intel Realsense d435i + qemu virtual machine
It works. Just remember about forwarding with a proper xhci host.

ROS Melodic on Slackware 14.2 – adventure continues!
So yesterday I wanted to post my notes from around October on how to install ROS Melodic on a Slackware 64bit system – yes, I’m boring, but honestly I like compiling ROS. It’s like an unhealthy, nerve-wrecking, time-consuming addiction that makes you smile in the end just for this one minute and it’s all worth it. Kinda like golf.

Designing compound planetary gearboxes in OpenSCAD
During my recent works with SEA (Series Elastic Actuators) I was using motors with gearboxes and was happy – as happy as a researcher can be in that scenario. So not very much.
All my gearboxes are scrapped from different servos, be it small 9g 1$ blue servo (SG-90) or a “slightly” more expensive Dynamixel MX-64. But what if… I design my own?
OptiTrack Motion Capture in ROS – rigid bodies and 3D points
This is one of the older things I did, but did not have enough time to make it into a post. So: the aim is to get a working stream of data from OptiTrack system into ROS Kinetic. A small catch: get individual points as well as rigid bodies.
SARAH – Screwless (Almost) Robotic Anthropomorphic Hand
A bit of honesty – I made this project by accident. True story.

Just notes on installing jekyll, because I keep forgetting how.

[NotesToMyself] ROS client-server on different machines
assume that 192.168.0.100 is the server and 192.168.0.153 is the client with Matlab
console on the server:
export ROS_IP=192.168.0.100
export ROS_MASTER_URI=http://192.168.0.100:11311
roscore
(and same with rosrun turtlesim turtlesim_node on another console)
matlab:
setenv(‘ROS_MASTER_URI’,’http://192.168.0.100:11311′)
setenv(‘ROS_IP’,’192.168.0.153′)
rosinit
robotctrl = rospublisher( ‘/turtle1/cmd_vel’ )
robotpose = rossubscriber( ‘/turtle1/pose’ )
twist = rosmessage(robotctrl.MessageType)
twist.Linear.X = 1
send(robotctrl,twist)
pause(0.1)
state = receive( robotpose, 1 )
[Fail] IOMMU and VFIO GPU Passthrough on a HP Zbook 14 laptop with dual graphics
(RAW, unedited dump of my notes that ends in a glorious failure) Goals for today:
- IOMMU groups on Zbook 14 G1 + Slackware 14.2
- GPU passthrough for a second graphics card (some kind of a Radeon)
- (maybe) Looking Glass to copy framebuffer to the Intel GPU
