![]() ![]() You understand why we really would like phosphor, it's a friendlier less spiky spectrum. Silly question to jan: do you have eagle sights? ) heh Okay well I guess it's hard to get phosphor red in strips Hmm I was going to get white because it ought to have slightly better performance due to reflecting any stray light The closeup shots of each color strip running seem to confirm my suspicion, you can see the bare die on the red elements I would guess the red is bare die, the pink is a bad phosphor redīut yeah, hard to tell from the sale here without knowing which is whichĪlso worth noting White PCB is 5.7mm,Black PCB is 4.7mmĭo only superconductors have 0 ohms resistance? They have two different strips with red heatshrink which i think is supposed to indicate color I hate to be a pain but does it mention a power consumption anywhere there ƬTION doesn't like technology that can see better than she can Seems unlikely if they're chewing more current than the othersĪctually yes I can get a spectroradiometer. Phil says these ones look like phosphor red, which is probably pretty good fo rus Guys can you tell if leds are native or phosphor Gotta save that extra $0.000003 on the BOM Well we can tweak the max voltage per channel using the internal trimmer. I think we decided that more than about 100w total dissipation per 300mm square board would turn it into a pyrotechnic.Īnd since red has the lowest forward voltage, it'll see the highest current with a fixed value dropper yeah Jan-: that'd be design fail, they're probably using the same value current limit resistors for all colors We made a test one using the normal wider strip and we found the red channel used heaps more current. How much power is 864 5730 leds, in red green blue and white? When soldering, tin is not isolating right?Ī total of 864 leds, four series sets of three in each colour. So it was easy for china to make a new board with the same microcontroller, and set the same VID/PID, and it works like a bought one :P This stuff is basically all the same price.īut when saleae made the logic, they used a microcontroller with no internal flash, the firmware is in their usb driver, all the uC has is a VID/PID to identify itself, then the firmware gets uploaded via USB on every start Is there a standard for color marking bomb cables ?Īlso if it doesn't do analog, it's not the same hardware So each colour has to have a multiple of three strips.ĭoes it work with the real logic software? w/o crashing all the time Viper-7: we need sets of three in series to get our voltage requirement. Monte Carlo simulations composition-related structural transition conformation hydrophobicity intrinsically disordered protein.Kmc: they are the same thing in a cheap case Thus, we achieve a better understanding on composition-structure relation of the natural proteins and the underlying physics. ![]() Our observations imply that the hydrophobicity contributes essentially to such composition-related transitions. Furthermore, the contributions of various interactions to the structural variation of peptides are analyzed based on the contact statistics and the charge-pattern dependence of the gyration radii of the peptides. These results outline the basic physical reasons for the compositional distinction between the intrinsically disordered proteins and the folded proteins. These thresholds of hydrophobicity and net charge are quantitatively consistent with the border line observed from the study of bioinformatics. For several cases, when the mean hydrophobicity is larger than a certain threshold, the transition temperature is higher than the room temperature, and vise versa. The corresponding transition temperature is found to be dependent on the contents of the hydrophobic and charged residues. Based on simulations using all-atom model and replica-exchange Monte Carlo method, a coil-globule transition is observed for each peptide. What induces such a composition-related structural transition? How do various kinds of interactions work in such processes? In this work, we investigate these problems based on a survey on peptides randomly composed of charged residues (including glutamic acids and lysines) and the residues with different hydrophobicity, such as alanines, glycines, or phenylalanines. Previous studies based on bioinformatics showed that there is a sharp distinction of structural features and residue composition between the intrinsically disordered proteins and the folded proteins.
