Front view: Rear view: Bottom view, feet; Two screws were hidden under the round calibration labels. Bottom view, two rear screws hidden under the feet: Side view, pull the sticky bits off: Complete top board: Ooh look, a 68B09E. The 63B40 is a programmable...
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...
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...
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...
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...
In the beginning of this year (Jan. 26), before building anything, I did a small experiment to confirm the most important idea of this project: hardening polymer clay with laser. Methods The materials are: Polymer clay: Fimo Soft (black)Laser: VoidMicro...
Kinematic systemRecently (early March 2024), I built the kinematic system to move the laser head and the print bed.The laser moves in X (left-right) axis, and the bed moves in Y (forward-backward) and Z (up-down) axis.All the axes are driven by cheap...
DHT22 Sensor: The ESP8266 in the diagram is mounted on a breadboard for easy connection and may be programmed to send the data it gathers from the DHT22 to the Raspberry Pi or directly to the cloud for monitoring.It is powered through a micro USB connection,...
In this image, we have outlined the setup for our temperature and humidity monitoring using the DHT11 sensor. The DHT11 is interfaced with the ESP8266 microcontroller, with the sensor’s data pin connected to the ESP8266's D1 pin. This allows the microcontroller...
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. ...
I carefully opened a TI-55 donor unit and inserted a 27ohm resistor in series with one of the digit cathodes. I captured the display sequence on my trusty LeCroy oscilloscope and dumped to the built-in thermal printer - TI-55 LED...
I like the STM32 ARM cortex MCU family. They are well documented, readily available, and cheap 'breakout boards' for them abound. The MCU retrofit must fit nicely in the space of a 28-pin 0.6" pitch DIP, so package size is key. The STM32F103 is...
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...
