Takhle dopadli tří ze tří zdrojů od „renomované“ Slovenské firmy IMCO Power… Samozřejmě po záruce. Nafoukl se u všech třech kusů filtrační kondenzátor na primáru a zdroj přestal pracovat. Považuji to za nevhodný výběr klíčové součástky, kdy by podle mého měl výrobce uznat chybu a věc řešit aby si zachoval jméno i po záruce. Není to zdroj z tržnice ale profi napájecí systém pro průmyslový sektor, ze…

Narozíl od České firmy BKE, která nám opravuje i po záruce zdarma moduly u kterých přiznali výrobní vadu, firma IMCO tuto situaci řešit tímto způsobem nehodlá.

Už před časem jsme měli špatnou zkušenost s jinými zdroji od IMCO u kterých byl otočený jeden kondenzátor a všech cca 10ks jsme museli měnit během cca. půl roku od nasazení. Tím pro nás spolupráce s touto firmou skončila. Už od nich nemáme ani jeden zdroj a máme po starostech.

PS: Děkujeme pane Neumanne za dvě vína „J. P. Chenet 0,25l“ v celkové hodnotě cca 100Kč, které jsme od vás obdrželi jako omluvu. 😉

Instead of use counter for S0 pulses counting, Smart Meter feature is much better…

Here is complete script with pulses calculation examples:

>D
>B
->sensor53 r
>M 1
+1,4,c,1,-20,S0
1,1-0:1.8.0*255(@1000,Energy,KWh,Energy,3) 1,1-0:1.7.0*255(@0.01667,Power,W,Power,0)
#

1kWh / 1000p/kWh = 1Wh/p => 1/60 = 0.01667
1kWh / 800p/kWh = 1.25Wh/p => 1/75 = 0.01334
1kWh / 250p/kWh = 4Wh/p => 1/240 = 0.00417

No other configuration is necessary…

Here is PCB (Eagle and gerber) for nice opensource project that provide way to use Raspberry Pi as RFID door access controller.

This particular design is customized for use with empty box from dead Mikrotik Routerboard RB2011iL-RM.

When I bought my Volca Sample I was disapointed with MIDI implementation – one channel for each track? Ehh? Immediately I grebbed Arduino and made MIDI adapter. Some time later I found mod with switch for mute. Today the cup ran… I added switch for memory too.

MIDI adapter is based on:

Points for solder switches connections – D301, D307 and common point:

Mounting Arduino Nano:

USB connector for programming:

DIN connector for alternative MIDI in:

+5V supply for Arduino stolen from capacitor:

All together:

Since I leave Ableton and switch to HW only setup I needed to make a classic midi out port to my LK. I found solution for older version of LK here: https://www.youtube.com/watch?v=IllVybz_2_8 but it is only for MK1 not for my MK2.

Solution is make USB-host to MIDI converter.

You need Arduino Pro mini and mini USB-host module with MAX3421E. I use library from Oleg Mazurov and Yuuichi Akagawa USB_Host_Shield_2.0 but I had to do little improvement of code because my PID od LK wasn’t in special known devices so LK wasn’t working until my change. Link to my update is below.

!!! IMPORTANT !!!

USB host mini module can’t run at 5V !!!!

USB host mini board doesn’t have 3.3V regulator – that is why I used two step down regulators – first bigger is for 12v>5V only for VBUS – You must scratch path to separate system voltage level from VBUS level – some boards have jumper pads for it but I haven’t. Second step down regulator is for 3.3V to power arduino and USB board itself.

My change is in file usbh_midi.cpp:
/* Setup for well known vendor/device specific configuration */
void USBH_MIDI::setupDeviceSpecific()
{
// Novation
if( vid == 0x1235 ) {
// LaunchPad's endpoint attirbute is interrupt (0x20:S, 0x36:Mini, 0x51:Pro, 0x69:MK2, 0x7b:Launchkey)
if(pid == 0x20 || pid == 0x36 || pid == 0x51 || pid == 0x69 || pid == 0x7b ) {
bTransferTypeMask = 2;
}
}
}

Pokud potrebujete provozovat ASD Clienta pod linuxem ve Wine, zde je navod:

So, here is what I did to make it work. First of all, unless you want to run Wine each time as root, add yourself to the dialout group, so you can access serial ports without root permissions. This can be done from Terminal:

sudo adduser <your_username> dialout

You should log off and back in for the changes to take effect. This affects not only Wine, but all other Linux application that need serial port access.

The first step is to make the necessary symbolic links. Again, in Terminal:

ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1
ln -s /dev/ttyS0 ~/.wine/dosdevices/com2

Adapt these commands for your situation. The first one is needed if you use a serial to USB adapter while the second one is for hardware motherboard ports. Add a symbolic link for each of the available serial ports. This command actually gives access to serial ports from Wine. And any Windows software where you can manually edit the serial port will work with only this. However many Windows apps allow user to select a port from a detected ports list. And they will detect nothing in Wine.

Now you need to add a Wine registry key as stated on Strangen0tes blog. Although you could use Wine’s regedit, it is easier to launch a text editor and add the required registry key(s). In Terminal:

gedit ~/.wine/system.reg

What you should add here is not clearly known, so you should try with the following options from Wine Wiki until you find something that works.

This is the common option that works with most applications:

[Hardware\\Devicemap\\Serialcomm] 1231984861
"Serial0"="COM1"

The other one is:

[Hardware\\Devicemap\\Serialcomm] 1131331688
"COM1"="COM1"

Both worked for me. Yet there may be apps that don’t read this registry key when looking for serial ports.

The association between COMx and /dev/ttyX is made in the symbolic link you made earlier.
