ALT A screen capture of a scanned document. There's a table with shortcuts for different operations like "Del Char", "Ins Char", "Reformat". At the top of the table, highlighted in yellow, it shows the information for "Oops!". The description reads: "This can be a real lifesaver. It recovers or backs up a function that you didn't mean to hit, as when you hit Delete Line instead of Insert Character, hitting Oops! will bring the line back."
ALT A poorly etched PCB with 4 big pads on each side. The left pads connect to traces that start very far from each other but come together in the center of the board. Then they go separate ways again to meet 4 output pads at the right side. Several clip connectors can be seen to the left, and two oscilloscope probes to the right, probing the output pads. A small Near field probe hovers over one of the output traces.
ALT An oscilloscope capture showing a very distorted and noisy sine wave. The scope can't even determine its frequency.
ALT A capture from the tinySA spectrum analyzer. Above the baseline noise two very clear peaks are present, and their frequency is shown up top: Peak 1: 6.996Mhz, Peak 2: 10.00 Mhz
ALT A small green FA-2 frequency counter sitting on top of a cardboard box. The screen reads 10000000.000 Hz. In the background, a Rigol function generator in frequency counter mode, measuring the same signal and showing 10.000,000,000,0 Mhz
ALT Closeup of a 4 Mhz crystal inserted on a single-row, 5 pin socket on a home-made PCB.
ALT The home-made Oscillator circuit held on a spring-loaded PCB vice with power connected and the output being monitored by a small handheld radio frequency counter. A Crystal is inserted in the black single row socket at the top, and the frequency counter screen reads 4.0033 Mhz
ALT Similar setup; home-made board held by a vice, but this time a 20 Mhz crystal is inserted in the socket. The frequency counter reads 19.993 Mhz
ALT The bottom side of the small PCB once etched, resting over a light blue towel
ALT Closeup of the claw mechanism. The body and both parts of the claw are 3D printed. The left side is driven by a DC motor with a reduction box, while the right side follows the right side movement (thanks to the geared claw rotation axis), turning a potentiometer as the claw opens or closes, providing positional feedback to the control board.
ALT A fully assembled Dygenguar robot placed on top the assembly guide, with some electronics repair equipment in the background. The spent runners from the gunpla kit are next to it.
ALT A figure of a powered-up Skeletor (from He-Man) is ready to attack Dygenguar, who assumes a fighting stance wielding his sword Zankantou in its expanded form.
ALT A close encounter between Skelegod (from He-Man) against Dygenguar, who is wielding his sword in its katana form.
ALT A 18650 battery holder connected to a small charger PCB, connected to a more complex module (a component tested) all roughly placed on top of a white 3D-printed plastic base.
ALT All modules mounted on the plastic base. A small metal tin transistor is placed in the component tester, that is displaying its main characteristics
ALT A rather big box on a black table. On the box there's a picture of Dygenguar, a very intricate robot in black, blue, red and white colors, holding a massive sword and ready to attack.
ALT With the lid removed, the box reveals its contents: A bunch of bags containing countless plastic pieces laid in sprue "sheets".
ALT Wooden keychain with the picture of a Final Fantasy moogle hugging a heart engraved, with the inscription "you are special" underneath
