My name is Dmitriy Dudarev. I develop electronics, and I love to create different portable devices. I also love music. A long time ago, in April 2020 or so, when the whole world was shaken by the terrible quarantine, I decided to learn to play...
I've posted a remark on the article "Creating a PCB in Everything" endorsing the design of single sided PCBs for DIY projects since they are far easier to replicate at home using techniques like toner transfer.I've then started from original Nanite board...
Hi there! Call for the community voice!my project at: IOTsatcom projectI need help to decide if to add extra features or not, to be specific:* Do you prefer a modular design or to have everything integrated on a single PCB board?Please, could you give...
Andrew Sowa writes about the PCB he designed in KiCad to surprise @Benchoff last weekend at the Hackaday Unconference in Chicago: Creating the Benchoff Nickel I thought of making the Benchoff nickel after I saw Brian's Hackaday,io profile. He has a hi-res...
As a long haul truck driver I use a thermoelectric cooler as opposed to an ice chest. The main problem is that it tends to freeze items placed nearest the cooling element. By placing a couple of 500ml water bottles next to the cooling element I can make...
PCB prototype refers to the trial production of printed circuit boards before mass production. After the electronic engineer completes the PCB circuit design, the process of small batch trial production to the PCB factory is the so-called “PCB...
In another forum I came across intriguing news: ALLPCB was offering free PCB fabrication and shipping, one order of 5 PCBs per month for each participant. Edit 2021-12-20: The offer is now only for enterprise customers. I guess it was too good to last,...
The Onkyo M-508 is undoubtedly one of the coolest looking power amplifiers out there.Giant needles of watt-o-meter.. imposing heavy as lead stance on the shelf. Everything about this amplifier says "turn the volume down before you hit the power." It...

Today I planned to mount an SQ12 camera on an old RC boat to make for some interesting footage. I pulled out the old boat, put in the batteries for both the boat itself and the controller, turned it on . . . . . . and you guessed it nothing! ...
Sometimes, a case exists for using multiple computers from a single desk. Several servers could be quietly grinding numbers in the background until they need to be accessed by the user for configuration or maintenance. Sure, buying several sets of keyboards...
In my numerous years in the electronics industry, we have come a long way. From using tape on mylars for PCB layouts to advanced CAD systems, the industry has moved what can only be described as light years ahead over the last 30 years or so.Gone are...
Over a decade a go I got a SNES from some relatives. When I was doing some cleaning I decided to pull it out. After cleaning the cartridge slot, it was working but the picture on the TV was pretty terrible. I picked up a cheap composite...
