Design Challenge n.13: Android app
Log from Green BMS
At the beginning of the project, I was thinking of connecting a touchscreen display as a human-machine interface, which is a typical solution used by many. But immediately I asked myself: how many times does the user of a BMS need to look at the display...

Design challenge n.4: voltage measurement accuracy
Log from Green BMS
Attiny84 microcontroller consents to measure the supply voltage, avoiding the use of an analog pin. How is accurate this measurement? In this phase of the design I made a bad discovery: connecting several controllers to the same power supply, I had different...

Quick-n-Dirty Stock PSU Notes
Log from Monoprice Select Mini Electro-Mechanical Upgrades
The Big Ass Cap for input filtering is a Nippon Chemi-Con 400V 220 uF snap in cap. I wouldn't bother with pricing out a replacement...---------- more ----------The PSU has a small step down transformer to rectified DC voltage via a 4A, though unmarked...

feature creep vol. {n+=1}: doors
Log from Minamil 3dp: another minimal CNC mill
Another log mostly about already-dead stuff that I took pictures of before breaking it down to make it different again. I tried to make this vulnerable corner at least not super fragile. It turned out to be super not fragile. It will take a much harder...

Testing PWM with LED strips and N-FET construction
Log from RGB WIFI Dimmer
Today I tested the N-FET construction with small pieces of LED strips. With all four PWM channels, all of them have around 500Hz an can have any duty cycle. The main result of this test is, that I have to choose other values for the pull-up resistors....

Final testring and confirmation of MOD's THD-N at 1kHz
Log from Audio - Phono preamplifier boost
Final results of my Art DJPre-II MOD. As input I have used my handcrafted ultra low-distortion oscillator with almost immeasurable levels below 0.0004% THD+N, which had to be attenuated by -40dB. ART-DJPREII-mod2-THD_ for_1kHz(-40dB_Input_WBOscilator-LM4562-0.0004prcTHD).bmp...

Design challenge n.5: what type of balancing resistors?
Log from Green BMS
Most of the low cost passive smart bms that are on the market, in my opinion they all have one limit in common: low balancing currents, from 30mA to 100mA Anyone who has experience with lithium cells, especially with Lifepo4, knows that with use, the...

Death of Bicep n°2 on 12/01/2024
Log from Arm Day
It is with deep sadness and a heavy heart that we announce the tragic passing of Bicep Number 2. At 11:27 AM today, we lost a cherished and irreplaceable member of our community. Bicep Number 2 brought strength, support, and resilience to those who relied...

Design challenge n.1: system architecture and bus isolation
Log from Green BMS
The BMS I had in mind consisted of a cell module screwed directly to the poles. To make it smart I had to use a microcontroller. The best choice was to use an ATTiny Microcontroller ATTiny84A powered directly from the cell. For the control unit I immediately...

Design challenge n.9: Arduino IDE Software functions
Log from Green BMS
Every software designer has their own way of programming, there is no single method. My job is PLC (Programmable Logic Controller) programmer and therefore I developed my project on Arduino IDE using the methods and functions that I normally use in Ladder...

Design challenge n.15: Pull-up resistors on I2c bus
Log from Green BMS
The last difficulty I had to overcome came when the project was finished. While charging the battery, noises from the charger caused communication losses. The good news was that the system went into protection, blocking the charge, and that the system...

Design challenge n.7: the fuse voltage drop
Log from Green BMS
The cell module circuit includes a 3A fuse connected immediately to the module's positive power supply. The fuse has a very low internal resistance (about 50 mOhm) However, this resistance becomes a problem during balancing, because the balancing current...

Chris 'n Zach blab about NeuroTinker, SBIR, and other random crap
Log from NeuroBytes
If you're exceedingly bored, I had the distinct honor of being on @Chris Gammell's excellent radio show this week, The Amp Hour. Listen to the episode here--we cover a lot in a brief (hah!) 109 minutes, including quite a bit about the history and challenges...

Argentum objects got parent pointers and safe-n-fast object reattachments
Log from Argentum programming language
Each object can tell who is its parent.These parent pointer are maintained automatically at a very low cost (single move instruction).This ability simplifies the handling of document data models and can facilitate integrity checks if needed. sys_getParent(existingObject)...

Design challenge n.2: what is the best way to set the cell address?
Log from Green BMS
The address of each single cell is written in a variable within the sketch of the Attiny controller: TinyWireS.begin (address); Obviously I couldn't create a sketch for each cell, it would have been a terrible project and impossible to manage !!! Imagine...
