Bad luck

robotics, toys for boys No Comments »

Bad news, everyone. All parts arrived, even the lost LCD was found in the post office. I came right on time before it got send back to Poland.

Taking the first steps with my Roboduino was real fun. I strated with the simple LED Demo and worked my way up till I got one RGB LED blinking through all the colors of the rainbow and even fading was easy. Next up was the LCD. I did all the soldering but before exposing it to the wrong current I wanted to messure the pins. Not a big thing, but I was a little too shaky that morning and made a short circuit.

My beautifully colorcycling LED went out, my Mac stated that the USB Device had been removed improperly and I was cursing. A quick reflash of the original demo that blinks the onboard LED showed, that flashing and some circuits still seemed to work. But neither could I get the LCD nor the RGB LED to work again properly. The absolute electronics noob got busted!

At first, I thought it would be the the regulator that went bust, but the more I test around it seems to be the processor itself that has some flaws with the PWM pins now. Pulsing works but my former setup and code just isn’t. Learning by burning is always a hard lesson.

I keep my fingers crossed that I am just too muddled to see the bug and so should you. If I will have to order another Roboduino from China, I will probably have no time when it arrives. Let’s just hope and enjoy the sun…

For your eyes only…

Omnibot ® 5402/TR5000Searching through ebay I found most of the parts I would need to get my Omnibot running again.

First off all I choose a roboduino board – found one on ebay, origin:China, so keep your fingers crossed that this will hit my doorstep.

Further I got a big 6v motorcycle battery that has the same size as the original from Tomy. Luckily it was already charged and ready to run, as I don’t have a charger right now.

LEDs, Multicolor-LEDs for the eyes – ebay was my friend again.

And a tiny LCD for the front to select programms and as debug screen.

During the last week the majority of the stuff arrived. I don’t know wether the LCD or the Roboduino got lost in our post office. I found the notice that the postman tried to deliver something and I was not at home. In the post office the guy searched for 30 minutes without luck. Now I am waiting for a call… and waiting… and waiting….

Meanwhile I spent some time on the new front panel that would sit in robots balley where the old tape deck and clock was placed. Björn provided me some old forex board (some kind of thin plasic board) that I cut and shaped till it now fits perfectly. I tried to stay close to the original look of the old panel – very 80s and so it fits the overall look.
all new frontpanel - tried to keep the look of the original alive
new panel made from forex board panel in place

Considering the eyes I wired up the LEDS . I choose to hook them up parallel and the non-electronic guy that I am, I just burned the first one because of a forgotten resistor. But as the saying goes “Learning by burning” I got it working now. Both eyes are lit up equally and look really great.
all wired up ooops something’s wrong… one eye darker than the other blue. all systems go and both eyes are lit up equally ahhh red…and all good green.

I tested the drivetrain and first I was shocked as nothing moved. At work we have a big power supply and in the end it showed up that every motor (Omnibot got two) sucks a full Ampere. No chance for my tiny power supply to comply those needs. The battery, I got now does have 4Ah and this works just fine.

Hopefully the missing parts pop up soon and I can go on.

Back to ebay searching for sensors.

Omnibot

robotics, toys for boys 4 Comments »

Omnibot ® 5402/TR5000Resurrection of this blog… or call it just a new project. Time has become a rare good and so I did not write much lately. Around xmas I finished my big Hellomat cab. Now it is powered with an old xbox, a special vertical version of Coin-Ops (thanks BB) and it is running perfectly. It took me two controllers till I finally managed the soldering, but no one is perfect and this is another story that I will pick up when adding a spinner to it.

Since I was a kid I wanted an Omnibot. When it first came out around 1980, I wanted it so badly that it was the only entry on my xmas wishlist and I remember taking part in a contest held by German cartoon mag “Fix & Foxi” – main price was a Tomy Omnibot in all its glory. Guess, that week I did not catch much sleep, thinking about me winning this robot. Off course I didn’t win, but thanks to ebay I found one, some 25 years later and I tell you what: I am still as exited as I was back than.

This emotion has got a slight setback, when I opened the package from ebay. On the auction picture the little bot was looking good and the text said it need some slight fixes and it would be a real collectible. The reality was something else: cracks, wrong screws, moved bodyparts, black color on the bottom, missing rubber band… the list goes on; in short a complete wreck that looked as if it was kicked down the stairs to the basement. I was about to send it back but Nadine saw it and told me that I could not throw out a little, helpless creature like that. Guess she was right. The lady who sold it got a negative feedback for robot abuse (and not seeing anything wrong about her description) and I started to take it apart in order to fix things.

poor omnibot. who can resist this look?  cleaning the bodyparts  

First off all some paint would be good to get rid of the yellowing parts. So this morning I took apart the arms and sprayed them with whit auto body paint. Now those look good and the complete body will be next up.

spray paint the whole body, arms and head new cloth for old robots - paintshop done!

The transparent dome on Omnibots head got scratches all over and fat crack in the center. Probably I will take it to caos place tonight as he has a lot of experience with scratched plastics. He already suggested to grind it with fine sandpaper and use some special paste that will softly abrogate the plastic and polish it with at the same time. If everything works fine all scratches should be gone. Considering the crack… well, I think I can’t make this disappear but was thinking about putting a band-aid over it, in order to show what he has been put through.

There are a ton more things that need to be done.. did I mention that he (from now on he is male) is constantly screaming when turned on? I am no electronics guy but maybe it has something to do with the shielding of my used powerplug (battery was missing – off course) or an old capacitor is defect. Well,  I guess I will swap the old internas with something new, like an Arduino board or roboduino. Pinter75 has done it already and the outcome looks really good. The hardest part to replace will be the missing rubber band on Omnibots foot. Maybe I can use t-molding or something similar. If you got an idea feel free to post a comment or contact me directly.

I am new to the Arduino stuff and will first up concentrate on getting him optically sane.

One link that no Omnibot owner should miss is The Old Robots.com - tons of information, manuals, schematics and and and.

So happy Robanukka…

going home

La Palma No Comments »

Packing up all the additional stuff we bought, was Nadines task and she mastered it. After checking out, we had a selfprepared small breakfast at the pier where Atlantic was throwing big breakers against the kaiwall, catapulting its spray five to six meter into the air and way above the wall. The sun was there and the whole scenery looked conciliable and friendly. A beer and an ice later, we went slowly back to our hotel, where we left our luggage. The nice lady at the reception called us a taxi to the airport and off we where. Good bye La Palma and let me say it with Arnies words: We’ll be back. Hasta la vista, baby!.

We climbed aboard our plane at dawn and we had plain view. During the flight we flew over several big cities, including Paris. I had a hard time using my pullover to keep the cabin light away from my lens but the plastic double glassed windows made a good shot impossible.

almost over

La Palma No Comments »

Almost our last day. We took the whole day and lingered through Santa Cruz. Basically we checked the supermercados for souvenirs. Later that day we went to a local tappas bar and had the best mojo of the whole holiday. Great, although it took some time to find it and realize, that it had places left in the back room.

Lo Divino  narrow street to our hotel old palmeros chatting all day long some more mojito backyard idyll making cigars is still a job on the Canaries night a the promonate clueless

above Santa Cruz

La Palma No Comments »

Hiking boots on – chcek! Map – check! Target locked: Virgen de las Nieves. The ancient church outside, above Santa Cruz is the place to not go on Sundays. Sundays, the palmeros visit their patron, the holy Maria that saved the city during a volcano eruption in an effort of letting it snow. Every five years the Bajada de la Virgen de las Nieves is held, where the statue weighting 2 tons is carried to the city center.

Climbing out the baranco, Santa Cruz is located it, we passed the houses on top and climbed down on the other side again. The whole way there I had the smell of a big steak in my nose. Right beside the curch is one of the better parillas (grill restaurant) known for their good meat.

We had no luck. It looked like the whole city had come up here and was waiting in order to get table inside. As it was a scene from a movie, rain set in. We had no chance but climb down to Santa Cruz again and to be honest: steep cobble stone pavement in rain is not better to walk on than on loose chippings, hence, it took some time. Back in town siesta was in full swing and I was so hungry.

We had some noodles in the hotel… not quite the meal I had on my mind, but hey, you can’t always get what you want, right?

altar in a small cove - you can spot them quite often up, up, above Santa Cruz the city streches till here and further banatruck Santuario de Nuestra Senora de las Nieves, seen from atop old palmero old lorrel tree inside the Santuario de Nuestra and the lady itsefl, in all its glory Hobbitingen? we couldn’t figure what this was, but it looks like an old church the ancient part of Santa Cruz no restauration needed

maos market and no bus

La Palma No Comments »

The first half of the day we wandered the streets of Santa Cruze. That afternoon the art and food market in Maso stood on our schedule. Maso was two towns away and we made first contact what it means to have no car on the island. No plan in sight and even the few shreds with information we found all said “about” and it was the first time that we really had to take a look at our watches – Las Tricias is timeless.

Finally we got on the bus and the next problem was when to get off again. No plan, no schedule, no signs at the station, nothing. Finally we found a young palmera that spoke english, but she wasn’t sure about our destination as well. Anyway, we got out the right place and found the market. A little smaller than the market in Puntagorda but again with great mojito. The local winegrower was giving away wine and roasted chestnuts – traditional for St. Martin on the Canaries. A little drunk, we climbed up that cliffy road to the bus stop. After an hour, we checked the schedule again just to find out that we had forgotten about the time shift. Canary Islands are 1 hour behind… so after a waiting for one and half hours in the cold and slight rain the bus arrived and we got home safely.

shop in the same street as hour hotel mainstreet, on the right the town hall square, oposite of the Inglesia El Salvador calling elvis… rain every now and than mascott of the area - so called enanos - some kind of dwarfes siesta real siesta… no one on in the streets mhhhhh… mochito with fresh sugar crane juice wine and chestnuts and music, off course and rain, in the end

we have to leave, but we’d rather stay

La Palma 1 Comment »

Karin started out to clean up our mess (we payed for it right when we booked) and we went down to Frohmuths Aloe Vera Cafe, had some fresh juice, said good bye to Ricardo and Amelie who where both working there. Than came the big goodbye. Luna was trailing along wherever we went. She seemed to know what was going on. For Nadine and me it was clear by now that this wasn’t the last trip to Karins little garden eden, but the next visitors were about to arrive and we had to return the rented car. In Santa Cruz we would have a room in a little hotel…. that was the deal.

After a small stop in Los Lanos – the secret capital of La Palma – we had to pass the three tunnels to get to the eastern side again. There dark clouds dropped from the mountaintops and we got another full rainbow, as if nature wanted to tell us that we are leaving the nice part of the island….. We arrived at dawn and parked the car. We considered Santa Cruz as a good bridge back to normal life, a quasi exit from the holiday to get accustomed to the city life again and it worked in every aspect.

Our room was smelling after mildew, a problem that all the other inhabitants seem to share. In effect everyone opened their windows, leading all to the same small backyard. In the morning, when the first alarm clock went off, everyone was awake. Welcome back to reality.

That evening we went to the nearby supermacdo and bought something to eat, went back to our fusty room and did not much exploring.

our kitchen for the last 10 days the old mill on the hill - here’s a close shot as we finally went to visit it on our last day Krains little garden eden, seen from the mill the way down to Frohmuths cafe luna didn’t want us to go - we din’t want to go eather goodby rainbow when we left Los Lanos - rain on the other side… and no sun the big tunnel that lead us back to citylife

Caldera de Taburiente

La Palma No Comments »

Caldera, here we come. This time we woke up the cocks, as we set our alarm clock really early. Small breakfast, check of equipment and off we drove. When we reached Barranco de las Angustias, where a shuttle taxi was waiting for us. We shared the costs with three other visitors and where off with 10 Euro. One hour later, we reached Mirador de los Brecitos where our journey started. From there on, the way was a constant descend with small upwards passages – take a look.

It is hard to pack all the details into text as there is so much to see. Every turn of the way you see different trees, rocks and formations. It is an absolute must for every visitor of the island and hikers alike. A really spectacular national park, with an constantly changing fauna and flora. Just take a look a the pictures.

The last half of the track we reached the riverbed and followed it with a short detour to the Colores, a colorful waterfall. We made it in 5 and a half hours and we took it slow, made lots of stops, took pictures or ate our boccadillos. It was by far the easiest trip of the holiday – long but really easy to walk and it was absolutely one, if not the most stunning part of the island. I have to say that those few hours where far too less time – we only got a slight impression of the great views and nature around.

That night Karin and Luca came over and we hat a nice dinner together – our goodbye dinner, so to say as the next visitors where about to come next day. We thought it would be a good idea to spend the last 4 days in Santa Cruze to get used to the life back home. Sad…. we would rather have stayed longer.

volcanos

La Palma No Comments »

Ok. Waking up because of the stupid alarm-roosters is not the worst and the sore muscles are normal now. Our confidence went back and so we decided to drive down south to explore the Teneguia and the San Antonio. Teneguia errupted back in 1971 and added some new beaches to the southern shore. Besides that, the whole pines around where burned. This summer big parts of the south stood aflame, but the vegetation is coming back. The canary pine is fireproof. It burns on the outside, and looses all its fir needles, but grows again.

This time we had our hiking boots and went on to explore the San Antonio and what should I say… we had about 1km to walk. Whatever we did in terms of gear and equipment, it seemed always wrong. Not quite, as the Tenequia was a little more challenging. You have a great view from atop the crater and stormy winds that try to blow you away. I really would like to witness an eruption. Back in 1971 Teneguia spit fire and melted rocks for a couple of weeks. After a funny oldschool movie about the volcanos and the island in general, in the nearby tourist center, we drove to Puerto Naos (new beach), the spot with the most beautiful beach on the island. Sure enough, the tourism is big there. Baywatch guys, towels and deck chairs all over the place. We enjoyed it anyway. Thanks to the Gulf stream, the atlantic is even warmer than Karins pool. Great.

big lava rocks that where cast around during the last erruption. Hiero, the neigbor island is to be seen at he horizon along the crater of San Antonio a not so easy passage on the way to top of Teneguia lava structures baywatching tools ;) the all new road to Puerto Naos - fresh planted palms for the touritst crater of San Antonio
