Decision on the Sensors
Log from Automated Rabbit Hutch Door
As mentioned in the last log, Thermopile matrix sensors sound like a very promising idea so did a short search wich ones would be available (see table below). But the would require at least some kind of image recognition which makes them complex to use....

PCB Bringup
Log from Battery powered LED pulse counter
I received the PCBs from JLCPCB which look great, however I have found some issues with the board: The TPS61023 boost converter IC I selected will operate down to 0.5V input, but I managed to overlook the point where it states that it requires 1.8V...

ROM disassembling
Log from HP437B power meter teardown
I installed this disassembler: https://github.com/Arakula/f9dasm and had a first go at disassembling.It is a pretty powerful tool.Much of the ROM seems to be arrays of words, making me wonder if there if they used some kind of FORTH interpreter to get...

log II
Log from home mri and fmri photo is AI production
version I what i made have 1X200 sensors. sensors have just stripes of metal Fe80Ni20 alloy sensors have contacted to that way ++/-- that makes magnetic waves make higher to high points and lower to low points of waves and noise just stay...

log I
Log from home mri and fmri photo is AI production
my first version of that log just get lost MRI first version have both max 0,5Tm two pairs coils i use Maxwell and Helmholtz coils what use to solve some problems to magnetic field Helmholtz and Maxwell coils have coil turns Helmholtz coils turns...

expansion log II
Log from home mri and fmri photo is AI production
I most time make log when I have less time I add some details what I don t say last time first thing sensor massive dont have one output there has 10 outputs new version must be 100 outputs new sensor I think made of film and have some micrometres layers...

Flashback : Prework
Log from TI-57 Programmable Calculator Hardware Retrofit
The more I read about the TI-57, the more I wanted to fix mine. Of course, these are easily found on a-large-well-known-online-auction-site for modest prices - typically $40 or less. Like most hobby projects, my goals were entirely devoid of practicality. ...

Blue Pill Emulation
Log from TI-57 Programmable Calculator Hardware Retrofit
Another key part of ensuring that replacing the TI-57's TMC1500 "brain" is possible is to ensure that the MCU has enough throughput to emulate it. My initial assumption was that a 64MHz 32-bit ARM MCU should be more than up to the task of emulating a...

Power Supply and Lid
Log from TI-57 Programmable Calculator Hardware Retrofit
Rcl57mcu wants a 3.5-5V supply. So, even if I could resurrect the dead BP-7 NiCd pack/lid, it won’t work for this upgrade. I will instead recycle the tried-and-true USB charged 3.7V LiPo supply that I’ve used for HP Classic, HP-28S, and TI-58/59 supply...

PSU #010, a PL320QMD
Log from Thurlby Thandar PSU repair
Fault label: "Numbers keep changing".2024-03-01Switched on, set dials to maximum. Leftt around 28.8V and drifiting, right around 32.88Dials set to minimum.Left side very slowly descends to 14.3 volts, terminals are at -0.424 volts.Right side slowly descends...

ESP32 to the Rescue
Log from SolarEdge Meter
On a whim I decided to put a LILYGO T-Display S3 into the mix and see if it didn't behave better. The code shouldn't require a change between hardware platforms thanks to the hardware abstraction layer in the Arduino development platform.I hit upload...

Monitor App
Log from Pocket Pad
Monitor App The Pocket Pad does not have any spare pins for peripherals, however, it does have bluetooth which can be used to connect to external devices and sensors. I had already made a Seeed Studio XIAO NRF52840 based environment monitoring station...

Black on Black or White on Black
Log from Pocket Pad
The display driver includes a command to invert the display and I have included a facility to choose an inverted display in the Settings app. I am still undecided as to which setting is more readable, however after implementing the analog clock app shown...

IVEE
Log from Calculators
IVEE, a FORTH-based Arduino calculator is a mostly completed project. It is based on IVEE by zooxo. Kudos to zooxo for designing this beauty and making it public. Please visit his repository, give it a star and watch his video explaining the features...

First quick test
Log from IR UART
Right after the assembly, a basic test confirms the modules work, though the pulse generator frequency is somewhat off. Replacing a 6.8 kΩ resistor with a 4.7 kΩ should fix this. When one module is fed with the 1 kHz signal (from the oscilloscope reference...
