Cannot get any monitor display. Get 0v < 50v display. Long press M gets me to menu. Upon MENU exit it briefly flashes an empty monitor display for less than a single second (no data), and returns to 0v < 50v static display. (see pictures attached). I have not figured out any magic to bring up any monitor / measurement display.

D: The wiring diagrams depicted are ( plus) common. Is there any (-) common wiring configuration? To place meter voltage / current on a twin voltage supply (one meter for each output voltage / current) I'd prefer a (-) common configuration so the (-) negative outputs are common.

Danny Oh, I did n’t try to connect the dual power supply. I think this product may not be connected to the dual power supply.

Fits four 26650 batteries, as shown in the photo My 18650 batteries appear just too long to fit Comes missing the 2 mounting screws to hold the circuit board in place. Without them the circuit board will not hold position when USB connections are mated. 2 clicks turns on or off light When you draw off the black USB connector the display indicates 5V 1A When you draw off the orange USB connector the display indicates 5V 2A

D: Searched for a manual. Has anyone deciphered all the button functions beyond the simple double click to turn the light on & off? Specifically I could not find any control to activate the 5v current limit selection that are laid out on the display.

Geekcreit® 8x8x8 Cubo di Luce LED 3D Blu Kit Fai Da Te Elettronico LED
US$21.09 US$22.99

D: My STC12C5A60S2 came unprogrammed. I downloaded STC-ISP and successfully flashed the .hex file and the light cube worked. Over time the cube began to malfunction. I've diagnosed a timing problem in the C source compiled into the .hex file. The timer is preset to 0xc000, and reset to this value after every IRQ [interrupt 1{} in the C source]. Evidently this provides insufficient time to complete the interrupt, causing the P1 output driving the ULN2803 to often have to await the timer to come all the way around again. Like the problem with the unprogrammed CPU I downloaded free tools and got past that. The only free compiler I'm aware of,Keil uVision (C51) will not compile the lightcube C source, as it informs that it is beyond the size permitted in the free evaluation compiler. My choices are: how to speed up the hardware clock, or does anyone have a recompiled source that extends the interrupt timing, or is there a free C51 compiler that will recompile the light cube source?

This thing is simply adorable! Cute as can be. Upon it's arrival I downloaded the user manual and then spent the next hour simply playing with it. I do a lot of construction of USB 5v powered devices and often simply use a hand-held USB power bank to test. This really expands the capabilities of what I can now power and test with any handheld 5v power bank.

This thing is absolutely incredible! I first watched a 7 minute review, and then pulled it out of the box, downloaded & loaded drivers, and downloaded & ran application. Imitating the reviewer I printed my own logo instantly, and then repeated scaling it larger. Worked flawlessly, and as easy to use as in it's review. For the price of a toy this is a fully functional, and incredibly quick and easy to use laser engraver.

Very cute. Even without a sunny window (in Arizona houses tend to avoid south facing windows) I just point a flashlight at it and with it's magnetic levitation mount it spin for a long long time. Makes a fascinating entertaining demonstration just like a crookes radiometer..
