A nice system for home and party is an light organ, who is made ususal with 3 channels (low, medium and high frequency), but I like with 4 channels, 3 for music and one for pause (or negative).
and a finished montage:
Usually, for made a simple square wave generator it use old 555 (you can see my experiments with 555 at Experimente cu “batranul” 555).
I like more CMOS chips… so, I use 4093 series (CD4093, MMC4093, etc) who is Quad 2-Input NAND Schmitt Trigger (see datasheet).
For use a single phase motor in both directions for made a hoist, whinch or for other applications must use a simple schematic named PSC (Permanent Split Capacitor), see docs from Washing machine two speed electric motor.
Base schematic is
For use in host when you need a limit switch for up, practical schematic is:
Acum, am dat de alt troliu/electropalan alimentat la 230V~ la care se umblase in schema si diferea de cea prezentata anterior, in sensul ca aveam la dispozitie doar 3 borne si o cutie de comanda cu butoane prin cablu, in care se gasea si condensatorul.
S-a pornit de la aceasi schema de baza , in schema “PSC (Permanent Split Capacitor). Acest motor are un condensator conectat permanent in serie cu infasurarea de pornire, ceea ce face ca aceasta sa devine infasurare auxiliara odata ce rotorul a atins turatia nominala”.
Dupa ce s-au refacut legaturile conform unei schema de conexiuni corecte, de catre acelasi coleg, Gigi:
Then I made a new “picture” for temperature:and I create a string with 512 elements (32 columns & 8 rows): Now, on my display I see:After this, I made a new “picture” for humidity:and a new string with 512 elements:Now, on display I see:
For power supply it use 5V (VCC & two VDDs):and interface for control is named HUB40A:Usual, this modules are used as street display with maximum 8 rows:and cascaded on columns: I search for info about HUB40A interface, but i found few usefull datas:and I found on board 2 chips 74HC245 and 32 chips MBI5026.Display has 2 big zone (upper & bottom rows), each with 4 square (4×4):Data is put serial like as ususal shift register, just there is 2 zone & 4 colour (2 red, 1 green & 1 blue):For control the display module I use a Arduino with this schematic:
For power this module I use a 5V/40A power supply module (can be used for 4 display modules).
