2014

  1. 旧ハードウェア & 旧 Slip21 / MCU/DSO のリモートセンサと XBee に搭載した温度センサを同時に記録
  2. Slip21 電池電極接触不良 / 電池電極の接触不良により,電流駆動による外付けセンサは出力低下を招く
  3. Slip21 西日による観賞魚水槽温への影響 / 短時間の日差しが曇り窓ガラスから差込み,光出力の急激な変化と軌を一にして水温も上昇している。水槽容量は 60L あり,意外だ。
  4. Slip21 MCU と XBee による同時測定記録 / Slie21 はワイヤレスモジュール XBee の温度センサと MCU の測定出力を同時に測定記録ができる。
  5. Slip21 MCU H8/3664F による2温度センサ2ホトセル測定例 / 気温の変化と異なり,日光の変化は急激である
  6. Slip21 Math 機能使用例 / 電圧の測定に DSO の出力を用いたが,MCU H8/3664,H8/3694 にも対応している
  7. XBee: 突発的に生じる温度上昇誤差の解消 / チャートをみると高インピーダンス回路ではサグが頻繁に観測されやはり,低インピーダンス回路の方が安定してよさそうだ。
  8. チャート幅拡大による効果およびサンプリング周期とピーク値の関係 / 周期が大きいと真の最大値最小値を見逃す可能性があり,公称精度を得られない可能性もある。
  9. Amplifier gain improves low ADC resolution by MCU / The smoothed measurement curve shows the fact that ADC resolution is very important to show a chart.
  10. Digital averaging decreases the sun light power measurement fluctuation
  11. Improved interface of semiconductor temperature sensor and App TDS298 / I found MCU averaging process is useful for suppressing the semiconductor noise.
  12. Road to Slip21 with realtime chart and TDS298 supports MCU / Slip21 is new version of Slip2.
  13. MCU board AKI-H8/3664F commnunicates with TDS298 / I have used old interlink cable to connect 3664F with PC
  14. Repair kerosen fan heater / I disassembled a fan heater and repaired.
  15. TDS298 1.01.10, Kiri198 1.00.33 sampled two Measurements at every minute, and Slip2 has recorded the Meas.dat for 25.1 hours. 13:39 Mar17 GMT+9
  16. I try charging Ni-MH, NiCd batteries for Xbox wireless controller and test used alkaline battery / Slip21 showed real time chart of the result of Tektronix DSO on Wiondows98.

RC or UAV related

I live near the Lake of Biwa (35° 20' N, 136° 10' E) in Japan. Target is to fly a UAV over the lake of Biwa. I hope to develop the UAV at considerably low cost, legacy technology.

  2. A Swiss solar plane flew by night
  3. Restriction to fly a UAV in Japan
  4. Design a UAV
