Lukse.lt

I’d like to announce another blog I am maintaining. It is mostly dedicated for products I make and develop and is located on kurokesu.com server. Current one on lukse.lt will stay as it is – I will post my random discoveries and interesting activities here.

Altera EP2C5T144 FLGA has no internal configuration flash memory and can be programmed two ways. One is to configure temporary – good method for testing and debugging. Another – over the same interface flash soldered flash chip. This is tricky and hardly documented step. In this post I am providing working recipe how to program […]

In this series of articles I will talk about how to start working with FPGA (Field Programmable Gate Array). Even basic knowledge of FPGA/CPLD architecture opens new understandings about hardware development possibilities especially if you are targeting real-time processing which might be complicated or impossible on modern CPU/MCU running operating systems.

This post is about vision processing and time-lapse video modification. As you probably know I own few stationary long term time-lapse cameras, and sometimes do some tricks with this huge data collection. This time I will walk you through improvised dot matrix display made from building windows.

This is preview of what I am working on. At first it might look like trivial project, but a lot of interesting stuff is ticking under the hood.  

Starting new project – LP0018D – best in the class digitizing touch probe/edge finder. After long research and many adjustments finally preparation is complete. Time to review first samples. Like all of my previous projects it is funded completely from my pocket, so should be reasonably priced and I am not rushed by crowdfunding bull*hit.

I was always fascinated by lightning. Long time ago, being a teenager I shoot lightning strikes many times with some degree of success. At that time I was using my dad’s old Zenit camera. While lightnings are always the same, equipment advances very rapidly. Today I will talk about spotting interesting frames from video and […]

To be short I will be talking about long term tethered time-lapse photography (it is also a good platform for construction camera). While final movie can be very short this kind of photography involves lots of planning and technical skills. During long time time lapse project a lot of things can go wrong. Also prepare […]

This is unique huge and heavy dice. It is made of solid aviation grade aluminium and weights 575 g (20.28 oz in imperial system). Dice is CNC machined, then sandblasted and black anodized.  

MQTT is a extremely lightweight machine-to-machine connectivity protocol. If you have Internet connected things talking to each other, you should consider MQTT as the best choice.
