We use the METCAL PS-900 Soldering Station for soldering.
We use the AiXun H314 Hot Air Gun for heat shrink.
We use the Riden RD6006 Bench Power Supply to provide test voltages of 0.1 V through 10 V.
We use the EEVblog BM2257 Digital Multimeter to measure current.
We use the EEVblog BM036 Digital Multimeter to measure current.
We use the Fluke 17B+ Digital Multimeter to measure voltage.
We use the Brother P-Touch D210 Label Maker to make labels.
We use the WilliamKlein Music Stand to hold the text book.
We use the Carpenter Mechanical Pencil to make notes.
