在距离众筹结束还剩 29 天的时候，TinyCircuits 的 Thumby 拇指掌机项目就已经达成了 Kickstarter 筹款目标。 其外形尺寸为 1.2 0.7 0.3 英寸（约 30.5 17.8 7.6 毫米），处理器为树莓派 Pico 中的 RP2040 SoC，辅以 72 40 单色 OLED 屏、压电扬声器、2MB 存储空间，以及续航约 2 小时的 40 mAh 可充电锂电池。 （来自：Kickstarter） 与任天堂Switch、Steam Deck 掌机、甚至手机相比，Thumby 的体型可以说是相当微型，此外 TinyCircuits 为其预装了五款复古风格的 游戏 。 Thumby 另一个有趣的地方，就是允许铜鼓哦通过 MicroPython 编程语言 / Arduino 集成开发环境（IDE）来打造自己的小 游戏 。 无论是《贪吃蛇》、还是《小行星》，都可以用类似 Game Boy 的 4 向 D-pad 和两个按钮来体验。如需多人 游戏 ，你还可以通过双头 micro-USB 线与另一款 Thumby 对战。 此外 TinyCircuits 写道，他们提供了一款易于浏览器使用的 Web IDE，能够在单个标签页里完成图像绘制和 游戏 编程操作。 Thumby - The Tiny Playable Keychain（via） 截止发稿时，Thumby 已经拿到了 900+ 支持者的近 38000 美元筹款、远超其 15000 美元的预设目标。 感兴趣的朋友，可拿出 19 美元去支持一下（浅灰色版本），或以 24 美元选购其它配色（带有纪念钥匙扣）。 如果一切顺利，Thumby 将于 2021 年 12 月向早期支持者出货（早年优惠已截止），并于 2022 年 2 月向其他支持者发货。

更新1: Thank you for your prompt response. However the question asks us to find the current flowing through XY when S is closed but not the current flowing through the whole circuit. Would you help me again? 更新2: The wer is 1.5A 更新3: I don"t understand why : Current through upper-left 1-ohm resistor = 4.5 x (2/3) A = 3 A Current through upper-right 2-ohm resistor = 4.5 x (1/3) A = 1.5 A 更新4: and Current through lower-left 2-ohm resistor = 4.5 x (1/3) A = 1.5 A Current through lower-right 1-ohm resistor = 4.5 x (2/3) A = 3 A 4.5 is the main current right? Then what are (1/3) and (2/3) represent? After S is closed the left 1-ohm and 2-ohm resistors are in paeallel the equivalent resistance = 1x2/(1+2) ohms = 2/3 ohms Similarly the right 2-ohm and 1-ohm resistors are in parallel equivalent resistance = 2x1/(2+1) ohms = 2/3 ohms The total resistance = (2/3+2/3) ohms = 4/3 ohms hence main current = 6/(4/3) A = 4.5 A Current through upper-left 1-ohm resistor = 4.5 x (2/3) A = 3 A Current through upper-right 2-ohm resistor = 4.5 x (1/3) A = 1.5 A Thus a current of (3-1.5) A= 1.5 A is diverted away through XY Current through lower-left 2-ohm resistor = 4.5 x (1/3) A = 1.5 A Current through lower-right 1-ohm resistor = 4.5 x (2/3) A = 3 A Thus a current of (3-1.5) A = 1.5 A is gained from XY. Therefore a current of 1.5 A is flowing from X to Y. [Although you could get the wer in this way the question is badly set. There is contradiction anyway. Since X and Y are joined together after S is closed X and Y should be at the same potential. Hence it could hardly say that there is a current of 1.5A flowing without a potential difference along XY]. It"s a very interesting circuit 2008-10-29 18:16:09 补充： physics8801 is right in calculation. Main current is 4.5 and the 2 resistors form a current divider. (1/3) me 1/3 of the main current 4.5 goes thru the 2 ohm and 2/3 of the current goes thru the 1 ohm. You calculate all the currents flow thru each resistor and then you e up with the value of XY and flow direction. Right here nothing to do with ohm"s law. Sorry Dr.physics8801 I did all the talking for you. Hope u don"t mind. Besides There is no contradiction in the circuit set up after I thought about it during my toilet time. No p.d. no current flow is not wrong but misguided here. It"s like a child"s IQ quiz and teaser for experienced ohm"s law guys. Imagine the current flows from one resistor to another resistor in series connected thru a wire. The p.d. across the wire of course equals 0 but the current does flow thru the wire due to the p.d. across the 2 resistors in series. That"s why I said misguided because our heads are loaded with only V=IR and cannot see simple things logically. Simple logic is: there is always current flow in the WIRES in a loaded circuit. This is my new theory in electric circuits. ha ha ha :) Don"t even think about giving me any points as Dr physics8801 really deserve all the credits. 2008-10-29 18:22:20 补充： grammar correction: "deserve" in the last sentence should be deserves. Anybody cares to check grammar for me? For free credit points? I"m a stingy guy. Everybody knows. 参考: Modern hypothesis in circuit theory written by me
