The chip in this watch has no conformal coating of any sort. If you wanted to, you could grab those little bonding wires.

I'm at the circulation desk in a mostly empty library today, so I brought this stuff with to work on.

Mixing electronics theory and knowledge of correct usage of electronic components, with their creative application

Circuit that I used to measure the flash duration of the microsecond flash. Saturation of the photodiode must be avoided, it helps to bounce the flash off of a closeby white wall.
Don't you just love my handwriting?
A BPX61 photodiode is used which does have the peak sensitivity well into the IR characteristic of silicon detectors. The 50ohm terminator is not required if the scope has a 50-ohm input impedance setting (mine does not). Also important to make sure that your choice of resistor is still primarily resistive at frequency so no wire wound resistors!
Yes, there's the MAC address. Yes, I know... But if you make it through my firewall into my house, your hacking my YBox is the least of my worries.
I bought a LAP-C-16032 some years ago and upgraded the hardware in the unit to have 32 channels. The h/w upgrade cost in the order of £5 total.
The memory device was capable of 128k samples per channel but was crippled by software to 32k only. There is software around that allows this to be edited but it never worked for me (wouldn't compile).
Being a h/w engineer I took a different approach. I constructed an interface using a small Arduino Nano circuit board (£1 off eBay) on a piece of scrap Veroboard and tacked some wires onto the onboard EEPROM (93LC46).
The Arduino is a 5V part and the EEPROM was running at 3.3V requiring a level shifter. This comprised of 4x resistive divider networks, 3x for the EEPROM and 1x for the GL660 USB interface device that talks to the EEPROM. The additional control to the GL660 was to allow it to be held in a reset state to allow the Arduino to talk without interference.
A simple Arduino script allows the EEPROM to be read and written. Decoding what to change is documented on the web.
The above has successfully allowed me to use the full 32 x 128k capability of the device, all for a very nominal cost. The change to the EEPROM allows the newest drivers and software to be run without modification.
