The resistive touchscreen
Log from Portable environmental monitor
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...

More 2369, with more caps !
Log from Hackaday TTLers
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,...

More Peripherals and some tablet bytes.
Log from WiiChuck
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...

Success!
Log from Voyage 200 Upgrades
So, the results are different than expected, but that is just fine. I'm running my V200 at 2x the speed it came from TI. For those who are TL:DR with my logs, you need a 1.21 kOhm resistor and an 18 pF capacitor. I never ran the MD5 checksums as I didn't...

Log 5 - 1 3d 3 servo leg experiment (incomplete)
Log from Quadruped learning project
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,...

So how far can you go? The 240km challenge.
Log from Smart BLDC controller for eBikes with BLE
The question The most asked question is always: "How far can you go with the battery?". And the answer is: "It depends!". The challenge The highest point that the Tour de France has ever passed is the Col de la Bonette at 2802 m (9192 ft). The distance...

BQ25504 Working Like It Should
Log from Ultra-Low Power LiPo Charger via Energy Harvesting
15 July 2018 First a word about packaging. I designed the BQ25504 breakout board to be as small as possible because I had in mind the idea that it would become part of an integrated (hybrid) power source. That is, the LiPo battery, solar cell, and BQ25504...

Z80 Pins and Debugging
Log from 3-Chip Z80 Design
There are two ways to get to the Z80 bus for external operations. RESET* - Clears PC and sets address/data bus to Hi-ZBUSREQ* - input - Address, Data, MREQ*, IORQ*, RD*, WR* to HiZBUSACK* - output indicates that BUSREQ* signal was performed (Hi-Z busses)...

Version 1 Testing
Log from Ultra Low Power Feather Development Board
Version 1 of the hardware arrived, and I have been testing it. Almost immediately, I discovered I had made a connection mistake on the 3.3V regulator, and the system would not run normally from battery power. I desoldered that part, and by providing...

FAT32 File Format
Log from OSI SD Card Operating System (OSISDOS)
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...

Tighter C-ving
Log from PEAC Pisano with End-Around Carry algorithm
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...

ROM checksum code
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
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...

AES-256 Is Not Enough: Breaking a Bootloader
Log from ChipWhisperer®: Security Research
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...

Heuristic breakthrough
Log from PEAC Pisano with End-Around Carry algorithm
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...

ETTL protocol with the EOS RP & 580 EX II
Log from Wireless ETTL flash conversion
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...
