I'm not big fan of the usb-on-mcu thing[/quote]

Why? It is a bit headache to program it for the first time, but when you get used to it, it becomes easier and easier. HID class is easy enough, everything can use it (Linux, Windows, etc.) and it does not need drivers. Once you have your libraries for it, the next projects are fast end easy. The price of ADuM3160 is comparable or cheaper then FT232 + digital isolator or digital isolator + PSU. And, only a single chip + 2 resistors + 3 capacitors are needed - one side is powered form the USB, and the other side form the MCU power. Only two connections to the MCU are needed in either case (UART RX+TX or USB D+ and D-).

:D because I have to make program run around usb interrupts and instead of usb working for me, I work for usb .. and I hate that. with uart I send char and forget about it, with usb your main loop is around usb and you do your "work" in spare time usb gives you .. not to mention how much flash and ram usb eats up :( (especially compared to uart).

the other thing is that 99% of devices I make don't need to talk non stop, they are stand alone devices that need to communicate with computer from time to time, so the whole usb thing is just waste of resources, I make a led port for uart available and I have my "universal" serial2usb card that I plug into that led port and I finish what I need to (debug, reprogram, download/upload data) and I use same "universal" board for all my devices .. (not to mention <2$ usb2uart cards on ebay that work like a charm, I pay only for usb connector locally 2$)

[quote author="neslekkim"]I have an Rigol ds2202a-s, i only need to learn how to capture with it, also got an agilent 34461A today but i guess that is not helpfull here.
What and where should I measure?[/quote]

Put Rigol into A-B differential mode (disconnect ground clips from your probes) or use differential probe and measure voltage on heater terminals.

Just for reference I'm attaching example from my HQ-SOLDER/30 (cheap) station. You can see simplest triac regulation without zero-crossing detection (the M channel, ignore 1 and 2 channels). AC half wave @ 50Hz.

It would be interesting to see 2BB output.

[quote author="arhi"]...and for JBC I did not find any mircowave tips at all (and if they have them they are probably like Weller paying royalty so again probably not too much choices and high price)...[/quote]

JBC has four Mini Spoon tips: C245067 C245938 C245931 C245965 for drag soldering. Looks like mircowave tips.

I am using C245064 for small components (i.e. TQFP144 and similar). In fact this is the tip I use most of the time. The equivalent is HAKKO T12-BCF1. It is tinned only at the front and one can put a really tiny drop of solder there. 0603 and 0402 resistors and capacitors are easily soldered with these tips also, although I rarely use components smaller than 0603.

Having two stations, one with C245064 and one with T12-BCF1 on it, I don't need a hot tweezers at all.

It is a shame there isn't similar C210 cartridge, but I will get one C210008 for extra small things. C210001 I already have, but it is really, really small.

[quote author="neslekkim"]I can use the T210 and T245 on both the 2BB station and the DIT station, same plugs, only the microtweezer that have an sligtly different plug.
So I would guess it should work?[/quote]

Did you use T210 on 2BB station? It seems like "unsupported" configuration according to JBC website (there is special CD-S station compatible with T210 - Output Peak Power 40W / 23.5V). Looks like you can destroy T210 tips on 2BB station because you measured C210 resistance only 0.2ohm.

Maybe is C210 detected on 2BB and lowered or disabled output power?

C210 resistance is between 1.8 and 2.3ohm. I am already running it on my controller. I put a limit on output power to 40%. My station can deliver around 130W/23V, so it is around 52W. I will put a real power limit after some time. This way it will not depend on mains voltage.

C210 can survive full 24V mains period, and this is what really matters. The rest is more or less easy.

In case of C245 tip you have no power output limits? JBC specification for 2BB station says Output Peak Power 130W / 23.5V. I assume they use 130W only for some short periods (such as warm-up), but don't expect they will put such stress on the tip for long time (while soldering some large joints).

Yes, used both T210 and T245, which is supported, also T470 is supported, but microtweezers are not supported.

You are right, now I see it in the CD-S and CD-B PDF manual. I was confused by JBC website information.

No, I don't. It does not need it. The transformer of the station is 100VA toroidal one, and it just cannot give more than about 130-140W. It ends with equilibrium between the tip's resistance and transformer voltage drop, so even when the tip is  switched on 100% of the time, the power cannot go much further from 130-140W.

I have 6.3A Fast blow fuse after the transformer. If it survives, then everything is OK. Well, it survives the C245 tips, and the C210 tips have so low resistance and so low heat mass that it needs a limit.

I can measure the heater's resistance and transformers voltage, so it will be easy to implement a power limit by software.

arhi, I have bad feeling about spamming your thread with JBC related questions. Are you interested in JBC tips support or should we move this discussion away?

I'm considering building simplest possible "two channel" JBC iron driver with support for T210, T245 and PA120 micro tweezers.

I don't mind the jbc storyline :) .. lot of useful info about those tips .. I don't plan attm to go with V4 of the driver and support them too (especially as the universal driver is already out there, why make another one) but good to have info all in same place
