Hacking the IKEA Luriga night light (no soldering!)

It has been a while since I wrote my last post. Unfortunately I have been much too busy with life and work to write things on this blog, especially since my little girl was born. But that very fact led me to do some modification to standard IKEA stuff. Now, IKEA is awesome, and I really appreciate their simplicity and quality of goods, as well as the little things that just show how well thought out their products actually are. From simple stools to LED night lights for children and from dinner table lamps to multi-functional bedding, they are absolutely [ . . . ]

What is a shift register

The official explanation Well, if you happen to read this page, you are probably wondering what a shift register is. Wikipedia manages to explain it as follows: “a shift register is a cascade of flip flops, sharing the same clock, in which the output of each flip-flop is connected to the ‘data’ input of the next flip-flop in the chain, resulting in a circuit that shifts by one position the ‘bit array‘ stored in it, ‘shifting in’ the data present at its input and ‘shifting out’ the last bit in the array, at each transition of the clock input” Now [ . . . ]

Making a DIN to BNC adapter for the C1-94

Now that the oscilloscope is working again, it’s time to make an adapter for it, since the old scope is still working with DIN, something that got replaced ages ago with the better and more solid BNC type connector. Or at least I was not able to find probes that came with a DIN plug anyway. So, after figuring out that the C1-94 is configured to have PIN 3 as signal, and PIN 2 as ground/mass, it is time to make a plug for it. For this I will be using a standard DIN plug, a standard BNC connector, and [ . . . ]

The repair of a C1-94

Going through the basement a few years ago to clean up and to throw out old crap, I ran into some stuff that I actually wanted to try and salvage. One of these items is an old C1-94 (spoken asĀ S1-94) oscilloscope from sovietĀ origin. (I think it was designed in Russia and not one of the member states, but i’m not sure on that). From what I can gather from Russian and German sources is that this particular model was designed and built in 1983, so this is well within the soviet era, which explains the tiny CCCP mark on the [ . . . ]
