Počelo je u ovoj temi:

Ja sam već nalemio par elemenata koje sam imao. Big Grin



Čeka se nabavka preostalih elemenata i nastavak radova, ali imam utisak da će saggit da me pretekne... Tongue

stvarno izgleda kao drajver za inject nekog SUS motora visokih performansi - a ne za lemilicu! Smile odlično izgleda a po izvoru ne sumnjam da tako i radi! sretan rad druže!

A na koji priključak za senzor treba da se priključi Hakko 907 štap?

Da li sam dobro razumeo, senzor se selektuje jumperom na onim letvicama gde piše "sen select"?

Kod grejača i senzora nije bitno kako okrećem kablove u konektoru?

Hakko ide na PTC.

Kod PTC je nebitan polaritet, dok je kod termopara bitan, mora se paziti dobro, inače crkava termopar i možeš baciti lemilicu.

Grejač vežeš kako hoćeš, samo paziš da ne spojiš PTC ili termopar na mesto grejača.

Izlemio sam još par elemenata...

Elementi su malo nepregledno obeleženi pa sam morao da otvaram Eagle fajl i da proveravam koji je koji...
Možda ove slike budu nekome od koristi pri sklapanju.

Zaborabio sam da na spisk za nabavku dodam keramiku i induktivnosti tako da će ovo da sačeka još koji dan.

L1 se može kratkospojiti. To je mala induktivnost od 1uH.
L2 je 330uH/0,7A na feritnom jezgru.

Da li neko zna gde se kod nas može nabaviti LM385Z u TO92 kućištu?

L1 ne bih preporucio da se menja sa kratkospojnikom, kratkospojnik ima cca 40-50nH a treba nam 1000nH sto je 25x manje! Njegova je uloga HF filtriranje.

LM385Z ima u Retam-u.

Zašto LM385 kad u BOM-u piše LM336?

A gde ima LM2574?

Ovo je Bogdan napisao na DangerousPrototypes.com:

Quote:The 1uH in theory cleans up the noise, but depending on the capacitors you put there it can work against you. I have 1uH only on one device and on all other devices I removed the 1uH and just shorted the leads.

Da zasto to?

LM385 je precizna "fiksna" zenerica a LM336 je promenjiva i to nam treba. LM385 i nema treci pin, tj NC je.

Ili se tu nesto ne slaze sa shemom … Cal-5k onda gubi smisao ako se upotrebi fixna varijanta … ili je drugacije to vezano ...

Čekaj...
I LM385 i LM336 su promenjive.

Ako pricamo o LM385Z, ona nije promenljiva. Ima varijanta sa -adj sufiksom i ona je promenljiva.

Koliko sam ja shvatio treba fixna 1,25V ili 2,5V. Prema njoj se određuje trimer. Ja mislim da upotrebim 2.5V referencu a za nju ide 5k trimer. Negde je to pisalo u Q and A koje je dao Bogdan. Za 1,25V ref treba 2k5 trimer, tako da se u oba slučaja na sredini hoda dobija potrebna vrednost od 100mA. Još samo kad bih znao gde se meri ta vrednost????

Ja sam upotrebljavao BOM koji je TDA generisao sa Eagle file-a za pločicu. Sećate se da sam pitao da li može LT1004 2,5V referenca (pošto je imam) ali mi niko nije razjasnio da li je pinout isti kao za LM385 i LM336, a ja sam bio u nedoumici gledajući DS-ove.

Znači odgovaraće i 385 i 336?
U Kelcu sam našao LM385-2.5 i LM385-5...
