I am making this post because not having one in the blog would allow people to call me an “ισαποστάκια”. In my country this is a derogatory term meaning someone that does not take a clear stance, a clear position in an argument or a demanding situation. It implies a person who has ulterior motives (to attach themselves to the […]

I’ve been working lately with this chip, the 8110 version with the 8 pins. It is a nice, more capable unit than the company’s successful energy metering chips, namely HLW8012 and HLW8032. Those two are used in many devices, most notably in the Sonoff smart home range, for power and energy consumption monitoring. Manufacturer is Hiliwi (or maybe Hiliwei), a […]
This is a board that converts the pressure in a pipe created by the level of a liquid above the pipe’s entrance, linearly, to a voltage of 0 to 10 volts and simultaneously a loop current in the range of 4 to 20 mA. It can be used with small effort as a meter, or together with a PLC or […]
In a previous post, I tackled the conversion of a CAD program (KiCad) output position file, to the pick and place machine’s (NeoDen 4) needs. The script I provided there did a great job in formatting the .CSV output file according to Neoden input requirements, and converting the component coordinates from the kicad reference to the p’n’p machine’s work space […]
The following document shows an application of a PIC12F1572 μC. It is schematic and source code of a diesel Generator Set meter. It measures the output voltage and frequency of the Gen-Set and then sends the values to the rest of the system through an optocoupler. It is not a general use device, it only shows the way I chose […]
At work we have a new Pick n’ Place machine, a NeoDen4 for small production batches and prototypes. It has many nice features, and some naggin’ quirks too. One of the latter is the way it imports the positions file from the PCB design software. The best approach so far is a back and forth procedure as I will describe […]
My beloved JVC GR-D73E stopped working! I really enjoyed having and using this beautiful machine. It was a compact, capable, elegant, well made piece of technology.It had captured so many happy family moments, it was with us in many key events in my family’s life. I asked around, the man who used to service them in my city retired many […]
Hello, I have installed a new certificate to my domain. Now you can visit the site using https: instead of http: protocol. I am using the free letsencrypt service. Edit 6-March: I am trying to enforce https protocol for all connections. Let’s see if there will be any problems… Have fun, Theodore
Hi guys, I have to add this info to the subject of my previous post for completion purposes. I tried to use ffmpeg in a script and compare the results with my Handbrake method. To find the parameters to pass to ffmpg, so I could use the libx264 codec as I wanted, I used the info from here. Ffmpeg’s -help […]
I just started this weekend, transferring my old home videos from some miniDV tapes to my PC. I have more than 50 hours of playtime on tapes from my old video camera that have been waiting for this moment, for an average of 15 years or so. Better late than never, they say, and now I finally had some time […]
