Re: Keyboards, Plastic, and Static Electricity
Interesting. Application notes I read recommended to place EMI and ESD protection (diodes and low pass filters) as close to the source as possible (i.e. near the edge of PCB where signal enters). Only power distribution network requires also decoupling capacitors and those should be as near to the M...

Re: Keyboards, Plastic, and Static Electricity
Almost all electronic parts have EDS protection built in up to 2 kV at least. Human body model. I doubt you need more.
As for as ussage: do not touch the metal parts of the keyboard USB connector when you suspect you may be charged. Touch a ground wire of your electrical outlet first.

Re: VAT and Customs; shipping a keyboard ti USA
An European company must ship it to you without VAT. You will pay price without VAT at the time of ordering. If here are any import duties for keyboards in USA then you will be paying them when the keyboard arrives to USA. There is no VAT in USA so you will not pay any VAT but import duties may be a...

If you send only one pulse to a piezo-buzzer then it sounds a bit like a click. It is rather silent though.

Re: Ground problems with handwired boards?
So, my pc chassis should be connected to earth through the 3 pin plug. Yes, that is protection by grounding. It is required by law ... probably in about every country.

Re: Ground problems with handwired boards?
In other words: if your keyboard requires a shielding ground to be connected to anything then you are likely having some other problem which this connection somehow mitigates. An example is a poor connection on the signal ground.

Re: Ground problems with handwired boards?
There are two grounds on an USB connector: Signal ground. This must be connected to the MCU ground . Shielding ground - this should be connected to the shielding of your keyboard case if it has any shielding at all. Most cases do not have any shielding (e.g. because they are plastic). In such case, ...

Re: PSA: Soarer's "Simple Logic Analyzer" exists and it's awesome
Well, maybe people do not use it because there are more comfortable alternatives and even cheaper ones (definitely when you want to make it from $20 teensy). But you can go with ProMicro for $4 and a bit of soldering, firmware burning and rather awkward waveform extraction. Or you can buy $6 Saleae ...

Re: Low profile Beamspring project
FreeCAD is quite usable. Considerably slower than commercial alternatives though. By slower I mean that there is still too much manual work which could be done automatically by the program (e.g. it does not guess the right constrains when drawing sketches). Also the OpenCascade (on which FreeCAD is ...

Re: Send language layout from USB HID keyboard
Not without a a custom driver. You can write some macro which will do it for you or an application which will switch the layout after some special input (e.g. on F13). And you can use something like Compose key or Unicode hex input to simulate changing layouts. Compose key support is native in linux...

I'm still using only about 1/3 of the pin current capacity. Compute the maximum current your buzzer will need and if you are bellow the pin current rati...

It is very likely you cannot do this for Manuform without redesigning the keywell or making the case bigger. Notice that you need one row of keys almost in plane to fan-out flexible PCB columns from. You either need such a row of keys or you need a bigger case to place the row of PCB connections out...

Re: ISO users
I preferred ansi to iso when I used a standard layout. Most keyboards use iso here.
