Yesterday before sleep I replace LD271 IR LED and this morning oficially started data gathering.On the pic you can see my morning glucosis test. Unfortunately the hour is wrong, need to fix it.What I found strange is the variation of measurements in...
Here's the tracking performance over 93 hours. The graphs demonstrate both the frequency drift over temperature and the much more gradual drift from aging. The enclosure appears to sufficiently blunt the cyclic temperature changes, and the...
It's been a while...Since the last post, I went ahead and had my gadget control the CH and DHW demands, replacing the room thermostat. This consisted of using the 'spare' optocouplers to drive a pair of 5V relays, and also using some DS18B20's to...
I have ordered the stepper motors, drivers and power supplies.X and Y axis motors:http://www.omc-stepperonline.com/dual-shaft-nema-23-cnc-stepper-motor-114mm-25nm-23hs453008d-p-163.htmlZ axis motor:http://www.omc-stepperonline.com/3d-printer-motor-nema-17-168a-45ncm64ozin-17hs191684s-p-17.htmlX,...
After my frustration with Vivado, I've done a discrete logic implementation of the "MVP".A hub with 4 connections, with 4 switches, so it's essentially 2 inputs and 2 outputs. Each input can be switched to any one output, no output, or both outputs....

For checking the MT9D111 two wire interface I started wiring the camera module to an Arduino Nano. Then, I programmed the Arduino based on the 16 Bit Register Read and Write Examples in page 9 to 11 of the Developer Guide. Wiring:MT9D111 ------ ArduinoGND...
I got stuck in trying to debug what went wrong in the Fuzix boot.To combat that frustration I've been working on learning Kicad 6 properly, while also trying to design a PZ1 PCB around the Raspberry Pi Pico instead of the Teensy.The Pico is really cheap...
So, after the last attempt (without acceleration) worked, I realized that the accelerations are hard to compute for two handles in parallel for an ATMEGA328 with the accelstepper library. The square root calculation takes a lot of time. So I have two...
In my other project, the Ai Wasp sentry gun, I successfully managed to deploy a model on the Raspberry Pi using MobileNet SSD, although the results were admittedly pretty poor. This time I thought I'd try YoloV3 as, theoretically, there is a complete...
My deflection pcb is all assembled. I am waiting for two 24V dc power supplies I ordered to come in. They should be here any day. I will use them to power the deflection pcb. Someone asked about the turns on the yoke. I used 92 turns per side...
