With the new harvest, I estimate that the perfect and maximal orbits under m=1M is around 100K. This starts to make quite a large .h file to include in the sieve generator. Not that it's such a concern but scalability, you know.... And embedding such...
This is an overview of the layout in which KGE works. Get User String (Round 0)Split String Into PairsIf Not Enough Then Add Specially Made Character Which Is Deleted During DecryptionUse Byte SubstitutionSwitch User Strings To IDs and Find Replacement...
With the wiring complete I wrote a small program in Python to test the lights, buttons, and switches on the front panel. To be clear this is NOT the KENBAK-2/5 emulator running a program (yet). As it turns out I did have to replace one of the LEDs...
July was a tough month, and August is no different. Due to some components arriving late, I've only been able to start my work on the Hackaday.io project with considerable delay. So I had to catch up with everything and squeeze the entire development...
Back to the workshop for the revenge of the return of the son of the Vintage Ring Oscillator ! This time with a new ally : the ceramic capacitor ! TL;DR : it's 60% faster ! But the V/F curve might look different from @Tim 's experiments... As usual,...
The amazon fairy dropped off a "NES Classic Controller" and a "Classic Pro"The classic pro comes up as a classic controller, The only difference is the analog R and L on the one I have are buttons and just return the max value when pushed. Although this...
So I want to make some notes because if I don't there will be less notes on the 3d 3 servo experiment, and I had a lot of trouble with the code so I want to get as much trouble into my notes. I struggled with the angle of the hiprotate servo in particular,...
I have continued debugging the hardware mock-up. The fundamental target was to program a simple RPN calculator UI with 6 operations plus a number of scientific functions. The integration with BASIC will come later, after all the hardware components are...
When you search google for FAT file format you get tons of pages on formatting disks. It's harder to pull out the detailed format of the SD card. Wikipedia to the rescue (Design of the FAT file system). A less technical FAT32 Wikipedia page is File...
lBefore I can get my hands on more numbers from the scan, let's go back to 147. C-ving. For the prime 1511 and higher, there is not enough data to get a complete histogram and there are histograms with 3 holes. We already know that the holes are symmetric...
The 5.21E ROM works file with the current board, but the 7.11A ROM uses a different pin for the vertical sync signal. This can be fixed, but then the 5.21E ROM results in no display. Rather than fixing the hardware (with a jumper to be changed when the...
I'd been pushing hard trying to get a demo of how you can break an AES-256 bootloader. This type of bootloader is often used in products for protecting firmware updates and a good demonstration of why you should care about side channel attacks as an...
I just had to follow the leads and trust my intuition. I had noticed that the last digits of the gPEAC moduli had a strange behaviour but I only dared to dig the matter these last days and oh boy was it worth it. I had already noticed that maximal...
The STM32 board was just a hair bigger than the PIC, but the biggest pieces are still the power switch, channel button, & battery. The plan is just to print an L enclosure which scotch tapes around the hot shoe & sticks up. The antenna will...
When entering a short test sequence on my remote this is what my receiver displays (a dot means an exact repetition of the previous packet):All on: 07 B0 F2 EA 35 90 01 B9 AC F9 .......................... 07 B0 F2 EA 35 90 00 B9 74 E0 .. Color red: 07...
