## Speaky riser board

| categories:

I soldered the speaky raiser board for the 9 Band modules as I mentioned during an earlier post.

The following set of pictures may give you an Idea how I made it, and how it fits into the Tranceiver.

## Speaky 9 Band Extension

| categories:

Yesterday I did some work on my speaky. I soldered together all the remaining Band modules and put them on a raiser board which fits into the Box.

Seriously I do not know how this will work on the HF side, mechaninally this is not a problem because the Box is much bigger than needed due to the frequency counter.

You need to do some cleanups to bring all the modules in.

The plug for the freq dialer must be grinded down a little bit. The whole Mainboard must go 4 mm lower what you can do by grinding $45^\circ$ angles into the metal cubes what enables you to leave the spacers away.

Test will come in a few weeks.

## Found pictures of my sidecar build...

## Got another engine

| categories:

I got another engine. A friend gave it as a gift.

• Hatz E75
• 350cc
• 6 ps

There is also an old Ural frame available together with some parts for a cool bike! Estimated fuel consumption should be 1-1.5 Liters. I hope.

The engine is perfectly healthy even if it was lying around for several years.

## Just found MathJax

| categories:

during some web research I found which is basically a javascript which can format LaTeX Formulas on your website.

Let's test:

$$U=\sqrt{P \cdot R}$$

all right.

## Speaky Progress....

| categories:

The Speaky board is soldered and ready for testing.

## Working on my Speaky goes on...

| categories:

Unfortunately the VCO is still not working as it should be :-(

## TeXCalc a Calculator for uncertainties and LaTeX

| categories:

Hi there,

during the last year I developed a command line calculator in python which can calculate numbers with uncertainties.

The Tool is also capeable to interperate with LaTeX doing python calculations within a

\begin{calc}...\end{calc}

environment. Finally you can set your results rounded to two significant digits directly into your LaTeX formulas by using

$\val{foo}}\approx \val[1]{bar}$

You can find out more on the project website: http://www.nawi.at/~zem/texcalc

## GIT is cool

| categories:

Most of the time. ;-)
you can easily forward a remote git repo to github by using a send hook:

(
PATH=\$PATH:/usr/local/bin
LOG=/dev/null
unset GIT_DIR
cd /home/zem/devlocal/phunivie
git pull origin master
git push -u github master
)

The hook is placed in a bare repository which is then cloned to a local copy on the server which is then pushed to github
of course you need to add a github origin, first...
git remote add github git@github.com:zem/texcalc.git

## first kubota test run

| categories:

Here a video of the first testrun of my Kubota D950

Unfortunately it burns oil on two cylinders, the water pump does not work and the crankshaft bearing is gone after the run. So it will take a few weeks more to get my second diesel bike on the road.

## Easter horrorshow

| categories:

The first set of pictures shows one of the exclusive Ural dry-enddrives in good shape. Those drives are dry to prevent oil from dripping on the street. Even if you fill in Oil to them, it will last for 20000 km until the bolts of the cover getting lose and the oil will leak out. You can drive another 10000 km when that happens.

The next set shows another end drive which has some serious cracks in its cover, so it ist useless until I figured out a way to get that fixed.

After I found some slightly useable parts I failed to mount a new enddrive ratio, the cover is not closing, I will write more about that when I know whats going on with that transmission:

Finally on the investigation of the Kubota engine I want to show you a short video of the Injection pump:

## coming soon... the vertical antenna project

| categories:

One of my current projects is to build a proper antenna system for HF amateur radio bands on the top of my lorry...

After it is almost finished I must admit that this was more complex than I thought. So I will soon write down my Experiences into 3 threads:

• vertical antenna for 10m - 40m
• antenna tuner up to 100w
• DDRR Loop for 80m - 160m

I will also show you what can go wrong, because I constructed almost everything twice.

## Final-drive issues

| categories:

Last weekend I traveled to the 20. Ratbike Wintertreffen near Ulm. On the campsite I discovered that the final-drive was not transmitting full power to the wheel anymore...

Obviously there are some pieces not in their place. Fortunately they are not important, except if you want to drive.

| categories:

Update: This article takes the Mark kid's do not try this at home because there is a proper solution, from the Suzuki Workshop handbook, which I do not have! The solution is to build out the camshaft and the tappets and grind down the valve shaft.

This weekend I made a huge Inspection on my GS500E when I discovered that the Valve playing on my left exhaust valve was gone. Unfortunately this was the one with the 215er Shim which is the smallest available.

I think the cylinder head is dieing, since the valve is digging deeper and deeper into it. Which is the cause of a lack of
service a few years ago. But why not grind those shims down, drive another 20000 km?

This is how I did it. First I drilled a 2 mm hole with a forstner drill into a piece of wood:

Then I angle grinded one side of the shim down. Being careful not to overheat the shim. When I had the right distance, I finisched it with a sander. I put the grinded and sanded side to the bottom, so the cam can pusch on the original side.

I don't know how long this will last, but I hope it is better than doing nothing until the engine breaks down.

## Diskbrake project

| categories:

I must admit, that those Russian drum brakes are not as relieable as i want them to be. Every 2000 km you have to adjust the cable tunings, every 1000 km you have to exchange the cable and also the steal within the aluminium drums is going very thin through the years.

So the cheapest and most propper way to get a better front break on your iron cluster is, to get a hub with a disk and build on the bike. That is what people told me. So I startet a search on several online services and found this for 15 bugs on willhaben.at :

It is a 19" wheel. I think it is propably from a Honda CB550 or CB750. So the first part of the new diskbrake system is there.

When I am thinking about new constructions I fell over a picture on Flickr:

This is a ruggerini RD210 engine with a centrifugal clutch I can't see any gearbox on that conversation.

## 3000 km on the Dieselbike

| categories:

Since the International Diesel Ralley in Hamm came this year again, I finally assembled my Diesel Bike, did 10 km testride and then I rode to the Ralley.

There is a Gallery on Flickr since I forgot my camera on the sofa:

http://www.flickr.com/photos/13755101@N03/sets/72157627482397253/

after the ralley I traveled to my dads home for two weeks.

When I was back in Vienna the Spedo says about 3000 km. The Gas cable broke and a Light bulb. Also there are some small oil leaks on the Gearbox I have to investigate. I also need a new Airfilter to get the noise levels down.

## Some pictures of the clutch repair work

| categories:

Here is the gallery of my clutch repair work. The clutch take out bearing and the Pilot bearing was broken, so I had to move the gearbox 50 cm to the back, exchange the parts and build everything together again.

When you do that work, it will not be bad if you exchange the clutch and the crankshaft seal as well.
