|These trees are located in or near Hannover, Germany. The first two have grown around some metal planks.
|Made with an USB microscope. Usually I use it to check the soldering of SMD components on PCB's.
|This is a Walnut I found on christmas eve. It has a shell that is made out of three parts instead of two. This is far more seldom than a four leafed clover.
|These are pictures of food that I bought that had some things in the package that it shouldn't have. This makes me think about how many insects we eat every day without knowing.
Keyboard without keys
|I took an old normal keyboard and erased the charakters of the keys. The longer you use this keyboard, the faster the brain adapts to the location of the keys. With this method you can learn to type much faster but the layout is very helpful in the beginning. The two main problems with this keyboard are that guests have difficulties typing and that entering passwords is unsafe.
Logic analyzer oopsy
|When designing digital circuits a logic analyzer is essential for debugging. Saleae offers a very good and low cost one. I use it almost daily. These pictures show the device after it got some 230VAC by accident instead of max 5VDC.
|This is a modern one chip SD card. Older versions hold multiple ICs. Note that the switch (in most cards) does not do anything. There is no electrical signal telling the card if it is locked or not. Some SD readers have a little sensor to detect whether the switch is on lock or not. Some programms such as viruses can bypass this. Most readers I have seen do not support the lock feature. In order to prevent data loss the switch should not be relied on altogether.
