On the 14th, I received my printed circuit boards for the Pixel Pusher. Yesterday, I got around to trying to build one of the three prototype boards I received. This is what a bare board looks like, component side up. My first task is to place...
Broadcom BCM4330 driver This one uses the Broadcom BCM4330. Be sure to use the correct firmware-file and NVRAM-file. These are the ones that worked for me: ubuntu@arm:~$ sha256sum /lib/firmware/brcm/brcmfmac4330-sdio.bin 004eb91ba7f1cd6eaf57b51f90d8004c5663c38175a8a9314a4e2f574cbfbd14...
I've been upgrading the case and PCB design into a new form factor, one that looks much more like a gun. Compared to the first prototypes, this has a number of advantages: Easier to aimEasier to see the OLED screen while aimingHas indicator LED's to...
I'm going to throw together something with (mostly) what I have. A lot of this pulls from the leftover debris that is the remains of the "SETEC Astronomy" project, and incorporates a few of the lesser goals of that project. I have an HP multimedia...
Hi all, welcome to Hack Chat. I'm Dan, I'll be moderating today for Leo Fernekes as we talk about "Harnessing Your Creativity." I know it's late -- or early -- where you are Leo. Are you online yet? Leo Fernekes12:00 PMYes - here and live Good morning!...
Annotated boards V1: buzzed out and hooked up. Note, I have no schematics, this is what I assume as I haven't tested yet. Just self notes. DOCK: Pioneer chassis has a self charging dock on the underside. Power board has a port J2 to control a solenoid...
This is the "classic" MK-52 speed test adapted from Dr.Shelest book.On the actual ESP32 hardware, it executes about 175 times faster. Actually, the processor speed is even faster, but the Resurrect updates the screen and checks for the STOP button 3...
Finally I got around to "verify" the stated operational temperature range. "Verify" in quote marks because my setup the bare minimum possible:A small test PCB (from a yet unreleased project) is the DUT and contains an ATTINY13A, the reference resistor,...
The current prototype of the MicroGrid Connection Unit uses a regular 5V Arduino Nano, and an ACS712 current sensor to measure the current flow to or from the grid. Unfortunately, the Nano33 IoT is running at 3.3V instead of 5V, but the ACS712 doesn't...
Now that I knew that the throughput to the PC could match the ADC’s rated sample rate of 1 GS/s, I had to make a circuit that clocked the ADC at that rate as well. This circuit needed to output at 1 GHz with very low jitter, as any jitter on the ADC...
Alternating pattern on the LEDsInitialization code is 837 instructions long. Hard coded to put alternating pattern on LEDs. ... MIF File -- File: C:\Users\HPz420\Documents\GitHub\Doug Gilliland\MultiComp\MultiComp_On_RETRO-EP4CE15\FrontPanel01\IOP16_ASSEMBLER\FP01_HLL\FP01_HLL_out.mif...
In this episode, we are making the drum computer 3-channel polyphonic! This requires some major rewrite and additional op-code side effect extensions. The 2x 16 registers obviously aren't enough for a 3-channel polyphonic 16 step sequencer, so we added...
Bill S12:25 PM@primetimber Ture, Then when everything goes to hell, the board gets a new CEO who says that last guy was the worst and continues to do nothing. Think VW Chris Ryding12:25 PMWhere do you tend to see more security vulnerabilities - insecure...
