There is a great, yet very little known, feature built into latest Windows OS, it is called SMB 3.0 Multi-Channel and it was available since Windows 8. So what is SMB? It stands for Server Message Block, according to Wiki, it is mainly used for file, printer, and even serial ports sharing between nodes in a network. And most usages of it involves computers running Microsoft Windows.

Playing With DigiSpark
I was thinking about building a delay circuit quickly and effectively and with small footprint. The idea is to delay a signal either from a camera or from other camera triggering devices and then trigger a flash after the delay.
Beside my need to build such a circuit, it is also my goal to share it and make it DIYable. Therefore, using a small microchip came up to my mind. One such MCU is Attiny45 series by Atmel (now Microchip) as it is so popular and you can use an Arduino to program it. While searching for Attiny45, I came across something that I have forgotten — DigiSpark boards! Continue reading Playing With DigiSpark
Build A NAS Server Using Raspberry Pi 3B
I was bored with Raspberry Pi 3B because my AlexaPi project had to be on hold. Why? Well, it seems the credentials that Amazon issued to me as developer expire pretty fast, I was only able to play with it for about a week. It was fun and exciting to play with, so it really makes anything else boring. So I think . . .
Reading Digital Caliper From Arduino
I have just encountered the need to read a digital dial indicator for another personal project. However, most of these digital dial indicators are “expensive” (normally cost about 30 – 100 USD), so I figure to just get a cheap digital caliper costing about 3 USD to start with. I totally understand that a cheap digital caliper might have different data protocols, but from what I gathered on the internet, most of these Chinese digital measurement tools use similar format — a clock and a data.
Arduino output matches (closely) caliper reading. There are some discrepancy, but I think it the poor caliper that is displaying wrong data
Not able to find my USB logic analyzer and my oscilloscope is dead, I decided to use an Arduino as signal analyzer. read more
Making a Shoot From Below Water Drop Setup
As water drop photography grew popularity, there has been many innovations about making water collide and splash. One such technique is the so called “Shoot From Below” setup. Basically, this technique utilizes pressurized or compressed air to push water jet up and then collide with water drop falling from above, the result can be astonishing.
Here is one example of Shoot From Below technique — yellow jets are shot from below with pressurized air tank and collide with red drops from above
This might sounds very expensive to do, but in actuality, it is not and it is safe, too. more …
