From a typing/gaming point of view, home and business versions are the same. Add a comment Step 3 Removing The Top Of The Keyboard Remove the top of the keyboard and put it aside. Add a comment Step 2 Separating The Keyboard's Chassis Use the spudger to separate the top of keyboard from the bottom of the keyboard. Main difference from the "home" version? The color of the underside. Step 1 Removing Screws Remove the Phillips 000 screw. I guess that's why the cheaper version of the K120 is called the "K120 for Business". The K120 is clearly designed to meet the requirements of gamers.first-person shooter gamers. Note that "ghosting" is suppressed there will be no key readings for keys you did not press, but in the "right half" of the alphabetic character keyboard, some key presses might not register if you press too many keys at one. It does not have a diode matrix (lol, most "gamer keyboards" don't have have this it might cost less than $10 more), but the keyboard matrix is arranged in a way than the "WASD" section of the keyboard is less of a subject of "ghosting" than the parts of the keyboard usually not used an intensively by typical games. I do, however, notice that the Kailh Copper switches are a little bit harder to press, even though pleasantly.īonus fact: the K120 is a "gamer keyboard". I vaguely remember that Logitech rubber domes have a nominal actuation forces of 0.35N (Kailh Copper with the "40g" rating having 0.40N), but don't nail me down on that. A bit harder to press than the K120 rubber dome switches, comparable to Cherry brown. It's less than $10!Īm alternative to Charry brown is, IMHO, "Kailh Copper" switches (40g, tactile, non-clicky), from China, I guess. My main keyboards are all K120.įinal verdict? You may use a totally not glamourous rubber dome keyboard like the K120 for 20 years, but I suggest that you replace it after 15 years at the most. Sorry, all my mechanical keyboards are just these samplers with six or nine keys for "special use cases". I had to get used to the new one, after I had adjusted myself to the old one which wore down for 20+ years, but the new, fresh one is definitely better. The old one was pretty good, but the new one was better. Logitech K120 Wired Keyboard for Windows, USB Plug-and-Play - Black. My old Logitech rubber dome keyboard failed after more than 20 years, and I replaced it with a new K120. But a fresh K120 rubber dome is still my favorite. My verdict? For mechanical keys, I prefer brown.
And I also bought a few Arduino boards (SparkFun Pro Micro 16MHZ 5V ATMega32u4 compatible ones, cheaper than the originals but work just as well) to convert these samplers into "real" keyboards (and also mouse functions) with specific pre-programmed macros for specific games.and business use. I have bought quite a few of these samplers. But you could connect the samples keys to, let's say an Arduino (which you need to program with a program you need to write) to convert such a sampler into a six or nine key keyboard. Non-functional because these samplers just have the mechanics, but no electrical connections. I guess the difference you perceive as "too light" is the tactile "hump", which is not present in red and blue keys.Ī few companies sell "key samplers", small non-functional keyboards typically with six or nine different key types. The brown switches require a slight bit more force to actuate than typical rubber dome keys (like the ones on the Logitech K120). Blue have linear tactile feedback, while brown gives you the non-linear feedback (with the "hump" you need to pass to register a key press) similar to a rubber dome keyboard. button || this->space_ panning) else if (panning = event->button.Definitely brown. This could be a quick fix for now.ĥ53: } else if (panning = event-> button. dont immerse the Logitech K120 keyboard in liquid., durable keys. Extending the if condition in /src/ui/ tools/tool- base.cpp: 553 with " || this->space_ panning" makes the panning escapable by clicking any mouse button. Spill-resistant design Tested under limited conditions (maximum of 60 ml liquid spillage). Substituting GDK_EXTENSION_ EVENTS_ ALL with GDK_EXTENSION_ EVENTS_ CURSOR didn't change anything.ĭisabling this line prevents space-panning bug, but also disables pressure sensitivity from my Wacom Intuos 3 :( Void SPCanvasImpl: :realize( GtkWidget *widget)ġ308: gtk_widget_ set_extension_ events( widget, GDK_EXTENSION_ EVENTS_ ALL) ġ309: // TODO: Extension event stuff has been deprecated in GTK+ 3 The problem starts when gtk_widget_ set_extension_ events is called In stucked panning mode, ToolBase: :root_handler( GdkEvent* event) stops receiving GDK_KEY_PRESS events I have Intel DH67BL motherboard which does not support PS/2 keyboard,mouse and am using Logitech K120 USB 2.0.
I did some debugging on the latest codebase rev. I have dual booted Windows 7 and Ubuntu 14.04. Nice catch! It works for me too: Linux Mint 17.2, Logitech K120
