I can almost guarantee my offsider here will be convulsing on the floor in the fetal position before the day is through. He's been dealing with a heap of stupid requests...
Customer starts their query with only:"What kind of memory card does my camera take?"
and
A discontinued line was reduced to $20 to clear it. It has no box or accessories. It is marked $20 'as is'. This normally retails for $89, even at this price it is below cost. A customer puts the unit on hold. Calls later. "Is there any chance of a further discount?"

Breaky. A Chicken Souvlaki Skewer and a Spring Roll. Life on the edge! Ah the TAFE days. Spring Rolls made up about 50% of my diet! Healthy! Mmmmmm. I like to keep my stomach strong by eating some Salmonella infested food on occasion. Oh! and there's only one way to eat the spring roll. Bite off the ends. Squeeze out the insides into your mouth then eat the yummy hollow pastry stuff!! Just don't tell my mum that I do that! I'm sure she would not be impressed

Work. Friday at last! Well, sorta. I have to work Saturday!
12:10 PM:
DAMN EXCEL!!!! Why does such a small bug mess up my spreadsheet so badly!!!! I'm talking about TRUNC() - a function that slices the fraction off without rounding the number.
TRUNC(1.25) = 1
Now the boggle:
I have $211.25 worth of money to take from the til in takings leaving the float... I have already taken from the til $211.20 in notes and coins starting from the largest denomination, now I need to calculate how many 5c pieces to take out. By the time the formulars have cascaded down from $100 notes to coins down to the 5cs that's the last one you will take out. So to check this we have a formula. I have $1.25 in 5c coins is the $1.25 of 5c less than what I have removed already? Nay, there is only 0.05. Cool. Divide the remainder by the money denominator ($0.05). To see how many will fit (1 in this case) we divide the remainder by the coin value and we get 1. So we need 1 5c piece. No probs. Answer x Denomination = Coin to remove. Swar. ONLY fscking TRUNC(1,0) seems to return 0.0000999998 == 0. SHIT!

Work.
Train was late, full when it arrived and the next one delayed too... Why am I not suprised? Cityrail will sweep that shit under the carpet now, everyone has gotten over the shiny new timetable and have resumed their routine of not paying attention to running times. Cityrail are going w00t! We got away with it again! Change the timetable, run it real tight for a few solid months then go back to how it was. Arseholes. I'm tired of the gorram trains!
Working at another store today. More stories of 'oh-by-the-way-your-working-here-now-don't-care-about-employees' type Big Business Acumen. <sarcasm> GG Bosses! Terrific in fact. Well done, I love you! </sarcasm>

Sunday...
Yummy chicken Kievs for lunch. Had to use them, defrosted them for another day but didn't eat them. Don't want to waste yummy kievs!
Watching some recorded Discovery Channel. Extreme Engineering! In this episode they are building a MASSIVE face shovel. MASSIVE! Very cool. I love mining gear. It's awesome! It takes 8 railway cards and 30 trucks to move it in pieces!
Oh! and the explosives! Muahahah! 190 holes. ~1ft in dia and 45 ft deep, blasting cap... 2 tonnes of amonium nitrate + fuel oil in each hole. Nasty.
Another documentry for me to watch! The top 10 tanks.

Friday off.
It appears that I have been strong-armed into a new position. Fscking terrific.
Today I made some more inventor parts for my new project: The CRO tool. It is going to have a Square + Sine wave generator with a frequency meter/display. This is the integration of two dick smith kits.

There we are P2220 and P704X. The knobs are almost-dayglow-green... The ones I have here are. I guess they mixed the plastic colours incorrectly. I will have to buy more SINCE TOMORROW IS MY LAST DAY...
The two kits are:

Crappy day at work for no particular reason...
Finished off (read made working) the video distribution amp. The chip was working but the image was just about white. I tested it on the DVD, you could only just see the screensaver logo bouncing around the white screen. No contrast at all, in addition only the first amp and last amp from four were working (this chip has 4 amps). I started checking for more shorts and found one! There was a short between the PCB pin and a ground plane. I fixed that up with a scribe and tried it again. No cure.
I read the datasheet about the chip (MAX497CPE) hopeing to find some troubleshooting info. Looking at the example circuit diagram it clicked. I decided to check if the chip was getting power - or at least power to the right places. I started by fitting a new battery to my multimeter. Something I should have got ages ago. After seeing which pins should be getting power I started checking traces starting at the regulators. The chip requires both +5V (pins 9 and 15) and -5V (pins 11 and 13). This is achieved using a 7805 (positive regulator) and a 7905 (negative regulator). BAM! no -5V on 11 and 13! I started checking for un-soldered pins. On this board there are no vias so connecting the top and bottom layers is depended on soldering both top and bottom pads of some components.
I ran into a dead end. I started manually checking the traces again. Whats this! A mistake on the board; NO! Immediately I was looking at ways of jumpering the -5V where I needed it. Looking closer at the middle of the board the -5V jumped straight off the regulator, through a filter cap and to an empty pad. Hrmmmmmm... There was nothing in this hole because I was making this as a Standalone unit. It has pads here to daisy chain +/-5V to other slave boards. Gee! Where do those traces lead on the other side of the board? Bloody pins 11 and 13! BUGGER! I stuck a PCB pin in there immediately and soldered it both sides. I didn't bother with the +5V because there are no traces on the top of the board taking +5V anywhere, just a pad surrounded by the ground plane.

Whoola! Workies. The finished product at last! Still lots more images in the gallery. I'm so proud

Saturday. Yay.
Started work on a video distribution amplifier for work. Should mean prudy pictures on all the screens. DVD players don't like having 10 TVs connected to them! TVs also don't like having a piss-weak signal. Some TVs just go dull, others roll vertically or flicker. Some display the blue screen of 'no signal'...
I used my new toy to take these photos. I couldn't be bothered dragging out my D60.

There is still work to be done on the power supply side of things. The IEC + Fuseholder needs to be wired to the switch and then to the transformer. An earth wire will also need to be run from the IECs earth terminal to the steel body of the transformer for safety. The leads on the transformer will be shortened and cable tied to make them look prudy.
I also need to grab a few metres of cable, some sidecutters, a DVD, a Drink and my wire stripppers. Why? So I can make the 12 coax flyleads I need to make to join the 8 RCA outputs to the amp and the 1 RCA input to the 4 inputs on the amp (while I have a drink and watch a dvd...)
I also discovered that one of my drill kits had some 'Spur Point' type bits in it. Excellent! Perfect actually. It meant that I didn't end up with the eliptical holes that you would get in thin plastic from a standard twist drill. Hence, all the holes that the RCA sockets poke through are beautiful and centred.

"Also known as a wood or dowel bit, they have a central point and two raised spurs that help keep the bit drilling straight. The bit cuts timber very fast when used in a power drill and leaves a clean sided hole. They are ideal for drilling holes for dowels as the sides of the holes are clean and parallel. Sizes range from 3 to 10mm. Spur point bits should only be used for drilling wood or some plastics."
I used a trick to drill the holes in the back panel. It involved printing a 1:1 drawing of the front panel holes, locating it on the panel with a rule to make sure that it was in the right place and then sticking it to the panel.

I am rather pleased with how neat and tidy the panels turned out! Naturally I knocked up a design in Inventor before I started. This helps immensly. It only took like 5 minutes to knock up a set of working drawings from the model. I love inventor!
