IIUser ManUal v1.6
Running list of errata
You are currently reading version 1.6 of the tinyTesla User Manual. Before continuing, go to onetesla.com/downloads and check
that v1.6 is the most up-to-date version. If not, download the errata or the latest version of the manual. This page will be continuously
updated with corrections.
Early kits may have the following extra parts, which are erroneous and may be omitted:
n female molex connector
n one surplus large ring terminal
n one surplus 6mm screw
In v1.0 of the manual, on page 3, the color code for the 68Ω resistors R2 and R3 was
incorrect. The correct color code is blue gray black.
In Step 6-J, regarding the ber optic receiver, kit builders have noticed that soldering this
component at too high a temperature can damage it. We are not exactly sure of the
proper temperature range, but we recommend soldering at no higher than 400°C.
An extra IGBT testing procedure has been added to Step 15.
Some kits have stability issues with the USB interrupter. There are several xes for this
problem, which relates to the Zener diodes. The rst option is to use a USB 3.0 port and
omit the Zener diodes. The second option is to replace the 3.3V Zener diodes with 3.6V
Zener diodes. Contact us at nikola@onetesla.com if you need them sent to you.
If you receive extra parts outside of the kit in your shipping box, they are for use in place
of the parts in the kit. In particular, some shipments have replacement Zener diodes for
the interrupter.
Note added to glue down the bolt in the endcap during assembly.
In Step 15, multimeter check of IGBTs section, sentence changed from “Meter between
pins 1 and 3 of X1, the large 3-pin connector. You should read open.” to “You should not
read a dead short.“
Properly sized heat sink template added.
Removed references to the tinyTesla interrupter chassis as it is purely cosmetic and will
no longer be included in the kit.
References to heat shrink removed, please use eletrical tape instead.
The secondary should read approximately 450Ω, not 600.
15V should be on pin 6, not 8 of the UCC27425.
Primary wire is no longer Teflon.
Fuses are now 4A instead of 2A.
Please check IC5, the LM7815 15V voltage regulator. Some kits may have an LM7915
instead, which will not work. Please contact us for a replacement at nikola@onetesla.com.
