Quick question about my PowerBoost 1000c if anybody happens to know. It doesn't appear to run everything with just the USB connected (no battery). I only get 1.2V. When I disconnect the screen, it powers on and the voltage goes up. It appears to work fine with a battery connected. Anybody know why ...

I have tried starting my GBZ build and most of my components seem to be working great so far however I have not been able to fully fit these parts in the case because the wiring I ordered is way too thick and rigid and it is causing things to take up a lot more room in the case and it is a big issu...

More specifically, wouldn't it just be the LCD's backlight switching on and off at the PWM frequency? The higher the duty cycle, the longer it stays on. https://en.wikipedia.org/wiki/Pulse-width_modulation#Duty_cycle So, the backlight turns on 146 times per second, and the higher the brightness / d...

Heh.. someone asked me to record the PWM dimming in slow motion. It's kind of neat. A lot like when you tried recording old CRT televisions. https://i.imgur.com/ZIpzUxo.gifv Luckily, you don't notice the flickering in real life (at least I don't). Though it's at 146Hz, so there's a small possibilit...

Thanks for this link. Do you know if that would work with the V3 + add-on board ? My GB Shell took 1 month to be delivered, I don't want to mess it up :D that link is for the v2 board which has a component mounted in that spot, so, no, technically, you do not have to do that... really, there is no ...

while waiting on my tinkerboy items to arrive I decided to do a pocket adventures one also. Any wiring guides out there for the pieces below? IMG_0252.jpeg when connecting the pi, just make sure to solder all the circled connections on gpio (at least) as well as the other pads/holes for power, vide...

are you running the spi screen? that tends to have a bit of a stutter at first for me too. i'm pretty sure it's related to the GPU throttling that the Pi does when there isn't much load. i think what happens is that the core_freq dials down to ~250hz when there isn't anything going on on the screen...

if its so tinkerboy has to mentioned this on his sales website... mono output is out of date! (

i think most 8/16 bit systems are just mono anyway (except genesis, notably), and with the single speaker anyway, mono usually gets the job done ok.

ok, you missunderstood me: I want to know if the headphone Jack provides stereo sound. I can only see one low pass filter for one channel on the pcb.

as far as i can tell, the v2 and v3 board do just output mono sound (which is why he has those mix-down instructions, i would guess).

how did you get working the mintybatterymonitor together with tinkerboy´s pcb, which is arduino based controls...? The mintybattery monitor need gpio input with adafuit retrogame... the minty monitor wouldn't work with the v3 board, directly. i used Helder's Retro PSU and its built-in ADS-1015. to ...
