The sink capability can be calculated using the following equation: Isink, max = (VZD2 - Vth[Q5]) / R30 (See schematics here, Sheet 3of6). Therefore for the current setup, and if we use as average Q5's Vth of 3 V it is (9.1 - 3) / 2.2 = 2.78 A. This is a huge current, but it last in milliseconds (previous down-programmer offered about 0.3 A).

I've received yesterday small batch of cardboard transportation boxes for BB3 kit:


how much does it cost to buy the box there? is it a custom size and cost more to order custom size?
spheres of influence, example linustechtips. can you feel the brainwashing? showing off equipment, etc. were you swayed and baited? with immense popularity (and social "titles"), can you afford to disagree?

Hi, I still cannot talk about prices. The customized box (i.e. drilled, painted and printed) with mounting frames for TFT display and AC/DC power modules with bare PCBs set will be available during and after the campaign. Anyway, I can say that it will be cheaper then general purpose metal electronic box of the same size that will requires customized front panel, etc.
