Task scheduler continued working for a month

You might upload Meas.txt, when you go out or make a short trip for some days. Task scheduler can fix working time. I have been set 96 for 6800 hours in the property of the task scheduling.

The task scheduler has been working for a month. The size of the Windows Page File stays at 333 MB. With more than 24 hours duration, Task scheduler seems to continue working for a long time.

Failed piles to arrange the tree

I failed to arrange the tree in my backyard before. I cut an old broom to 3 pieces.

The ground was too soft to support the load of the slanted tree.

The sun radiation effects outdoor air temperature

01Ar temperature changed like saw shape in the morning yesterday . My wireless sensors also have photo-cells. The varying temperature was caused by the sun radiation, I show the chart.

Deteriorated NiCd charging current recovery

I charged deteriorated NiCd batteries dissipated by GE digital camer A1455. 200mA flew in the both batteries.

They were 115 and 60mA each, I charged them on Oct 27 the last time. I found that the charger circuit might not work well then.

I show the charging currents this time. The initial currents were alternative. 

The CH1 wave form was 0 to 188mA, 188 to 324mA, and 0 to drop. The mean value is 200mA. The frequency was 22Hz. It lasted 10 minutes.

The CH2 was normal rectangular shape at 40Hz. The duty of on/off was 15/8.6ms.  It lasted 15 minutes.

Good charger can charge even deteriorating batteries, I think. One has to confirm that a charger can charge deteriorating batteries or not. But to confirm it, one has to prepare deteriorated sample at first.

GE A1455 camera dissipated NiMH Toshiba 2000mAh. I charged them by my charger. The initial charging current exceeded more than 200mA.

CH2(E4) flew in a rectangular shape at 34Hz. While CH1(E3) flew in strange steps, 0 to 280mA, down 100mA and to 0 at the same frequency 34Hz. I had better improve 2SK1290 gate drive circuit as CH2.

Deteriorated NiCd battery for wireless XBee power suppy

#03 BAT has also dropped. I measured the individual battery voltage by DMM PC510 at 21:02 Nov 23.
NiCd1: 1.253V
NiCd2: 0.049V

The dropping chart is shown as below.

The both batteries duration term is  16/10/26 16:15 through 16/11/23 21:00. The duration time was 28 days 4 hours 45 minutes. NiCd2 might be deteriorated, but the CH2 circuit of my charger was not improved then.

I tried charging these ones, and show the charging current chart.

The initial charging current of NiCd2 is 50mA only in spite of empty. I set NiCd1 in the CH2 battery holder after 0 am. And the charging current exceeded 70mA at instant, but stopped charging at once.

I will not use NiCd2 for wireless XBee power supply. I also confirmed that the charged pair of NiCd1 and NiCd2 did not start GE digital camera A1455.

#02 BAT work time and the charging current

As #02 BAT voltage gets down, I measured each voltage by DMM.

E21: 1.011V

E22: 1.039V

They worked #02 17:45 Aug28 through 10:30 Nov22 during 85 days 16 hours 45 minutes.

I am surprised that the charging currents were less 100mA, when I began charging them.

The CH1 charging current hardly flew. I had better improve the CH1 circuit as well as CH2.

I took off E22 from the CH2 BAT holder after the current was less than 50mA. The E21 charging time was one fourth of E22. It seems that this pair of E21 and E22 deteriorates harder than another pair of the same Eneloop E11 and E12.

Now I have changed #02 for #03, #03 is indoor. The sharp drop of 02Lq occurred, when changing the #02 batteries.

Air-cleaner on cabinet circulates low temperature air

I moved a small cabinet under the desk. The cabinet makes screen. I put air-cleaner on it.
