VoltLog #7 – In The Mail

A list of the items I show on this InTheMail video:
2.4 inch 320 x 240 px TFT display module based on the ILI9341 lcd controller, complete with touchscreen, uSD card slot, 128Mbit flash, independent font chip and the required power circuitry. ESP8266 modules (3 different variations), a small solar panel, waterproof enclosure and Li-ion battery cells. uSD card holder thing. 13W LED 5050 E27 lightbulb. Breadboad + breadboard power supply + jumper cables. 0-30V 0-2A Adjustable lab power supply kit, unassembled. A bunch of components I ordered from Comet Electronics.

DSO nano - portable digital oscilloscope

I was really interested about it when Seeed Studio first announced the DSO nano on their blog, unfortunately I was not able to get one of the beta’s which they offered in a limited number at a lower price. The specs they released don’t advertise for too much power from this portable but it’s style and the fact that is portable together with the low price tag should compensate for the lack of power. And don’t get me wrong on the power issue, the 1 MHz bandwidth is still enough to cover your hobby needs. For me the only big disadvantage is the fact that it has only one channel, but it compensates with the ability of recording readings that you can later compare with the actual reading.

I would love to give you more details about this portable oscilloscope, but I have to wait until I can get my hands on the DSO nano. I’m currently waiting for Seeed to list it on their product page so i can place an order.
