pyspice uses ngspice and xyce as backend, capable of simulating MOS, JFET, diode and more

everytime the fucking machine restarts, it fails devastatingly.

#!/usr/bin/expect
spawn pwmconfig
#expect "Giving the fans some time to reach full speed..."
expect "If you do not want to do this hit control-C now!!!"
send "\03"
expect eof

hope this shit works?

echo 255 | sudo tee /sys/class/hwmon/hwmon6/pwm3
echo 255 | sudo tee /sys/class/hwmon/hwmon6/pwm1

i have install something other than that. like i8kctl, some thermal controllers by intel (thermald)? but still gpu fan not spinning till now.

already have cpu frequency under control by running temp_throttle.sh

Found the following PWM controls:
hwmon6/pwm1           current value: 255
hwmon6/pwm3           current value: 255

cpufrequtils

throttling cpu frequencies by temperature incrementally

the desired temperature is 60.

usually when one throttles the CPU temperature, the GPU cannot be overheated.

it is turning my core i7 into a pentium 3! but not entirely cumbersome.

利用淘宝铜片焊接的WiFi天线 安装在开源机械臂上 利用固定点抵达算法 扫描算法 自动探测WiFi源与方向的对应关系 机械手臂应当安装在比较高的支撑点上 周围不要挡着WiFi天线 有比较长的延长线 扫描算法不得超过线材的限制（旋转角度控制）必须得知初始态的绝对位置

智能手表防水 泡温泉 外壳

智能手表都不能泡温泉 洗澡

可以考虑做智能手表的时候添加耐温耐水蒸汽的胶水 也可以考虑做防水汽的外壳 塑料透明保护壳 胶圈要和塑料壳之间用耐温耐水汽的胶水粘连 胶圈之间添加波纹 纹路 增加密封强度 耐压 用铰链链接 卡扣扣住 或者双卡扣

如果外壳需要留空间给按钮 用橡胶按钮加耐压防水胶 或者粘贴实体按钮 硬质按钮加橡胶密封层 注意连接处面积要大

旋转的按钮就不要旋转了 因为无法密封 比如苹果iwatch 只能点按

外壳一般有配套的表带 不用原来的连接装置
