On carpet tracks, the owners are very particular about what traction compound you’re allowed to use. Rightly so as the tire rubber and compound ultimately work their way into the (expensive) carpet.

On dirt and clay it’s not as regulated for club racing because it’s just dirt! This has unintended consequences… One popular “tire sauce” is liquid wrench. You can even find it listed on the pros setup sheets. While I admire the inventiveness, take a look at the Material Safety Data Sheet (MSDS). With warnings like Use only outdoors or in a well-ventilated area and Causes skin irritation, it makes you wonder if there’s a better way.

When using liquid wrench I would wear nitrite gloves to make sure it’s not soaking into my skin. Wearing gloves for tire chemical treatment is generally a good idea, but if I can also avoid irritating fumes, even better.

Super Simple Hard Cider

My wife got me this hard cider kit from Brooklyn BrewShop for Christmas:

Unfortunately apple cider was very out of season at the time. As we get back into the height of cider season, I want to tell you how easy it is to make hard cider with three (3!) ingredients and have it ready to drink in about a month.

2WD “Backslash” Wing

What’s a Backslash, besides this: “\”? It’s a nickname for a RC buggy made from the chassis of a Traxxas Slash. Some people call it a Backslash, some people call it a Sluggy (Slash + Buggy). Whatever you call it, the original 4WD variation is the most popular because it’s extremely simple to mount an […]

What’s a Backslash, besides this: “\”? It’s a nickname for a RC buggy made from the chassis of a Traxxas Slash. Some people call it a Backslash, some people call it a Sluggy (Slash + Buggy). Whatever you call it, the original 4WD variation is the most popular because it’s extremely simple to mount an 1/8 scale wing to the shock tower and change the body to a 1/8 scale buggy one.

I wanted to do one for my 2WD Slash. There are a couple of extra hurdles on the 2WD, like the gearbox being behind the shock tower, but it still seemed do-able. So here is what I did to mount an 1/8 scale wing to my 2WD Slash.

HobbyMate AIO FVP Camera on a LaTrax Prerunner

I picked up a HobbyMate HB298T AIO FPV Camera for my Tiny Whoop. It’s discontinued, which is a shame, but you might be able to find them on eBay. I got it because of this very specific feature most micro-FPV cameras don’t have: Built-in Microphone. BUT… I haven’t installed the addition to my FPV goggles […]

I picked up a HobbyMate HB298T AIO FPV Camera for my Tiny Whoop. It’s discontinued, which is a shame, but you might be able to find them on eBay. I got it because of this very specific feature most micro-FPV cameras don’t have: Built-in Microphone.

BUT… I haven’t installed the addition to my FPV goggles that will allow me to receive and record sound yet. Video however is working nicely and I look forward to adding audio to the mix.

Virtual KidsCamp MSP 2020

At home, we’ve created a parody on the Tim & Eric song/skit “All The Food is Poison”

Our version is called “All The Things Are Cancelled” and it goes like this:

All the things are cancelled, all the things are cancelled!

  • WGI – Cancelled!
  • Drum Corps – Cancelled!
  • Sportsball – Cancelled!
  • State Fair – Cancelled!
  • WordCamp – Cancelled?

WordCamp US 2020 was canceled, citing online event fatigue. But the organizers of WordCamp Minneapolis / St. Paul did not. Would we just be another notch in the bedpost of 2020 online event fatigue?

To be honest, the organizing team did contemplate canceling WordCamp Minneapolis / St. Paul as the Coronavirus pandemic continued to linger. But everyone agreed that pivoting to a single-day virtual event was a better idea – and we stayed the course.

Carrying stuff by bike: fishing rods

I am not a gun nut, but this build was inspired by this comic and conversation:

Looking at it made me think that a similar, but more useful application of vertical bike rack storage, would be for fishing rods. Moore Lake is just down the hill from where I live, and it’s stocked with Bluegills and Bass 🎣

I made this fishing rod holder that attaches to my bike rack for less than $20, mostly from scraps I had in the garage. It holds four rods, but you could adjust it for as many as you’d like, as long as your bike rack setup will accommodate them.

Flysky Noble NB4 – A great left handed transmitter

Disclaimer: I am not left handed, but this is a great transmitter whether you’re left or right handed…

During quarantine I played VRC at least once a week to get my racing fix since all of the tracks were closed. My daughter would often ask if she could try racing as she watched me play. But converting my Spektrum DX3R to left handed operation meant taking it apart to move all the components to the left.

I’d been eyeing a Flysky Noble NB4 because it’s a pro-level low latency transmitter, and it’s killer feature is that it can instantly switch from right to left-handed operation.

Since I wasn’t getting to the track anytime soon, I sold my DX3R and ordered a Noble NB4 with some extra receivers. This write-up will go through some of the features and how I set it up because there are a few things you’ll want to consider.

Duplicati setup tips for Linux, RaspberryPi & MacOS

Single-user vs service

Before you install Duplicati, there’s one question you need to ask:

Does this computer have multiple user logins (that you want to back-up), or is it primarily used by one user?

This is important because you can install Duplicati in one of two ways: to run as a single-user, or to run as a system service that is available to all users. By default Duplicati is installed for a single user, but if there is more than one user on the computer you want to be able to back-up, you’ll want to install it as a service.

If you don’t install it as a service, when Duplicati tries to read files that belong to the other users, it will get a permission denied error and won’t be able to back those files up. You don’t want to find out that your files weren’t backed up when it’s too late.
