On the door handiness in Autodesk Revit

I was working on semi – automated solution to enter door handiness in Revit models. The existing solutions are either quite expensive (like Reforma Swing Direction) or has weird assumptions.

My intial setup is Dynamo and the Dynamo Door Set Handing module from http://archi-lab.net/. It has fine tutorials, so you only need to create your model in Dynamo.

The weird thing on door handines is it is different in some countries.

  • Door handiness in Germany is defined as hinge position on the door, when one is pulling the door to open. if the hinges are on the left side, the door is left-handed, and if the hinges are on the right side, the door is right-handed. I will refer it ad “DIN – style”.
  • The IFC, together with ISO 16739 defines door handiness as the position of “positive Y axis”, which is definitelly the position of door handle when puling.  I will refer it as “ISO – style”.
  • Americans use ISO style, but also has “reversed” option. I still have no idea on this option, as “reversed right” is “left”.

So, what’s to do?

Pinout for A-364 4× 7-segment LED panel

The panel i bought may be named A-364E, probably appearing from Para Light. At least the seller, http://www.evita.lt/a364e-indikatorius-a-364e-9_2mm-4x7segm-dinaminis-raudonas-a?search=a-364 writes this information.

The panel itself has markings like “VP 474 AG” and “C1250d5 T”. Quite useless information. Well, at least it is red 4x 7-segment LED indicator, sharing common anode per every digit, quite similar to http://www.aliexpress.com/store/product/A-364E-L-DIP-12/637061_2051431574.html

BEWARE: it’s impossible to control this panel using SAA1064 LED panel driver, you need HT16K33 or similar.

The first pin is bottom left, counter-clokwise, as usual. The first digit is leftmost.

The pinout as follows:

Pin 1 : “E” segment;
Pin 2 : “D” segment;
Pin 3 : “Decimal point” segment;
Pin 4 : “C” segment;
Pin 5 : “G” segment;
Pin 6 : Common anode for the 4th digit
Pin 7 : “B” segment;
Pin 8 : Common anode for the 3rd digit;
Pin 9 : Common anode for the 2nd digit
Pin 10 : “F” segment;
Pin 11 : “A” segment;
Pin 12 : Common anode for the 1st digit.

Atnaujintas Evita.lt ieškiklis Mozilla FireFox’ui

Jei dar nepastebėjote, evita.lt pakeitė savo puslapio išvaizdą ir variklį.

Gražu.

Kai kam. O mano senasis evita.lt ieškiklis nebeveikia. Teko pagaminti naują, tinkamą dabartinei (as of 2015-01-05) struktūrai.

Pakeliui išsinagrinėjau kaip greitai ieškoti Spikare, AKA rcl.lt kataloge. Mažu kam pravers?

Taigi, ieškyklės Firefox’ui:

MS IE? O kam, kas jį dar naudoja?

Target and the result

A picture worth of thousand bytes
pcb

Slightly overexposed – 2× 6W UV-A (or “black light”) lamps is slightly too much at c.a. 8 cm distance at 4 min exposure time;
The text is just too small – add another 10 mils and hope it will be OK;
Maybe the PCB is too old? It’s kind of NOS and may sit for 6 to 10 years in my stock;
There was slight underetching in the top left corner and had to be corrected by hand.

The PCB is for 0,05 – 5 sec timer for MOT welder. The base is NE555 in SO-8 casing, two swichable capacitors of 47uF and 470uF provides the time range, adjusted by 10k trimmer.

Meet the Sulley


Sulley, from inside and his broken vertebral column

 

Sulley’s sad. He can’t bounce any more. Nor to wiggle his tail.
The toy for $10 supposed to last more than a couple of days, i suppose.

Thank You Disney, for moving your engineering department closer to the manufacturer.

Search engine providers for Firefox and MS IE

I’m lazy person.
Here are search engine providers for Firefox and MS IE web browsers.

I’ve added keywords for these search engines, like evt for Evita.lt, lmn for lemona.lt. Now, searching in particular site is as easy as Lotus 1-2-3: type in keyword and the term you need to search in the address bar. So, typing lmn ds180 will search for ds180 in Lemona.lt site.

Firefox Lemona.lt Evita.lt Datasheetcatalog.com
MS IE Lemona.lt Evita.lt Datasheetcatalog.com

Cheers.

Managing HP P400 RAID card

It’s a summarising memo from the last Saturday.
What supposed to be slowish disk, actually was dead drive on array.
Thanks for the supplier, the entire collection of SAS drives was just waiting to be installed.

It’s possible to configure RAID adapter from the BIOS stage, but it’s more interesting to configure it on the live system. What you need is configuration tools for the adapter card. And they are called “hpacucli”. Ok, ‘CLI” stands for “Command Line Interface”, “hp” is too obvious. “A” could be for “array”. What “cu” stands for?

Debian repository is at http://downloads.linux.hp.com/SDR/downloads/ManagementComponentPack/pool/non-free/.

Get it, install and read on.

Run “hpacucli”, it should be located in /usr/sbin.

To get information on installed RAID cards, use

ctrl all show

The utility can warn you on the recommended firmware upgrade and will print the controller(s) information:

Case story: move the location of Revit Server 2012 models

Here is the other issue: due to the fast install of Revit Server 2012, the location of model was not important. After the server’s role was changed to “Central” instead of ‘Caching”, i wanted model be stored in more predictable location.

Again, I had no wish to reinstall the whole server, including w2008r2 server.

Case story: change role of Revit Server 2012 without reinstall

Our company was running a caching Revit Server 2012 instance, to be able to work on a project. The central server was set in the kingdom of far away and was serving three architectural offices.
Recently we had to take care of the model created and the Revit Server 2012 instance itself. I hate to touch working system, but i had to.
