Ahhhh I see how that could happen. The navigation on wordpress blog's is imho totally confusing at the best of times, it's really hard to find older posts that are important.

Try this post - INTRO H i F i D U I N O

In there it recommends searching for a screen that is - 204 LCD HD44780 - the VFD's discussed in opc's NTD1 thread should be a drop in replacement for that screen and need minimal hardware changes and no software changes. I have contacted noritake about those VFD's and waiting to hear back from them at the moment.

Thanks very much hochopeper, you save my life again��

Looking forward to hear your good news on the VFD.

Just finished the SSLV for BIII, 5.25V 650mA output. It takes about 10 minutes for the output to be stable, drifts from 5.25 to 5.207. The temperature for the two FET are very cool. The Q101 is 40 Deg, Q106 is 34 Deg with ambient 28. Small size sink shall be good enough.

Hi, what is the value of Rx01 you use? I use 4.8ohm for 500mA and the heat sink is smaller than yours is quite hot after 30minutes.

The Rx01 is 3.3ohm with input voltage 15Vac and I installed all 4 green LED. The big heatsink give me a wrong impression that the heat dissipation of Qx01 is small. When I use a heatsink of 1/4 size, the temperature raised to 60 deg within 5 minutes.

Just completed the SSLV for the BIII and Legato. Also, receive re-fund from TPA for the excess shipping cost, I hope this is an indication of the BIII is being shipped

Find this VFD display, much cheaper than Noritake.

But also not compatible with the arduino libraries written for HD44780 LCDs, so the code needs to change significantly to use that screen I think.

Actually, the 169 pin lead on that display actually probably leave you building an adapter board to interface to the arduino anyway, after which the time/cost of that task would leave you better off with the noritake

Agree with your view. I received the Arduino and Matrix LCD today. I found that I had a HD44780 LCD bought previously for a project never happened Now, I have everything to start my lesson on Arduino.

Waiting for your good news on Noritake

Still have no news on the BIII shipment, ordered the WaveIO. Spent couple hours to read the "Programming Arduino" and get something showed on the LCD

Will connect the IR sensor & rotary encoder to test the Code.
